Digital night vision is the future, but it comes with some liabilities that traditional analog night vision does not - one of these issues is latency.
In this video we do a direct comparison by driving in low light between a PVS7 Gen 3 analog unit and the @SIONYXnightvision Opsin. The older Sionyx unit, the Aurora, had some known issues with latency, is that still an issue with the Opsin?
What was the moon 🌙 faze?
It was half.
@@InrangeTv Sorry if I missed it - were you using an IR illuminator with the Sionyx?
@@dannydubya1 I doubt it. It would be like shining a flashlight on the wind shield.
No, there was no IR illumination used with either device.
PBS of guntubers (complimentary)
Government funded propaganda?
Function over form.
Quality over quantity.
In a sea of meme filled silly channels, this is an island of sanity.
Big up Karl!
I found this highly illuminating.
I'm glad you mentioned lights inside vehicles. Years ago in A'Stan my job involved driving civilian vehicles, usually up armored Landcruisers or soft skin Hiluxes. We'd make flaps our of cardboard/garbage bags/duct tape to fold down over the dash board so we wouldn't blast out our NODs. We'd even make flaps to cover the lights around the gear shift. Some folks added extra switches to the electrical system so they could just flip a switch and go completely black. It was also pretty common to add IR lights to the outside of the vehicle so we'd have IR headlights whilst driving under NODs.
The last time I used night vision was as a tank platoon leader in 1979. I don’t remember what NVG we were using, but the advances since then are significant. At the time I was blown away by the technology. Interestingly, I can get better results then we achieved using my iPhone camera.
The digital night vision is crazy crisp compared to the analog nvg, and you can actually see color which is cool.
The image you can see on the tube is better irl though, much of the blurr is just from recording through an optic made for an eye. Also the tube is not showing any noise, so its far from being really dark in this video, its pretty low gain so the ccd shines.
What i really do like is the better depth of focus you can see on the spar tire, thats an issue with the optics of older iit devices, you cant see your own hands when the thing is focussed to infinity.
I just saw a Task and Purpose video that touched on the difference between digital and analogue nvgs, but that was in reference to the capabilities of the PLA. Also, it was more focused on the theoretical and doctrinal side of things vs this video's practical focus. This made for a nice counterpoint/investigation of the topic in context.
I saw that video as well.
Great video and I totally agree that digital NVG’s might be the future. Especially since the lowered cost makes them more accessible for other countries’ armies as well, further driving development.
I’d be very interested to see the Opsin in some “target identification” scenarios as well. Like have Russell walk around the desert, Sasquatch style, and compare how easy it is to spot him.
I'm concerned that someone might panic and shoot Karl outside of a closed range.
Love it! Russellsquatch tracking comparison.
One thing you didn't remark on but which I was impressed by is the capability of the digital NVGs to filter out (or at least mitigate the effect of) bloom from point light sources. I noticed that the PVS7 has stars that twinkled much brighter, but when you rounded the corner to observe the lamps around the building, there is a much more pronounced effect on the PVS7 too. Not so with the digital NVGs.
Great video!
Karl's neighbors: "Oh great. Kasarda is out driving without lights tonight. Again" "Call the sheriff?" "Na, when he crashes, we'll just go out and help him pickup the pieces."
Never crashed. :)
Nice to see your VW again 🚙
Just bought the Opsin. Very happy. As a novice, not having to worry about burning your multi thousand dollar unit is a huge bonus.
This was a better comparison than the first video. Thanks for sharing. I hope you keep up the night vision videos
The Opsin's footage genuinely reminds me of the scene in Generation Kill where they're driving to their objective at night with NODs, seeing it from the perspective of the camera and not Ray or Colbert. It's crazy crisp by comparison, and I'm not really amazed you could drive considering you also ran Midnight Brutality with it, and quite well I might add. That being said, the Opsin looks pretty good for digital but for me it comes down to cost; at the price it is, I could probably pick up at Gen 2+ WP, or Gen 3 PVS-14 for around the same amount of money, or at least a little bit more, but it'll definitely get there technology-wise, and as far as digital NV goes the Opsin seems like THE piece of kit to use.
Definitely interested, especially if these monoculars come down in price over time like most technology tends to do, versus analog NV tech which is cost-limited due to how the tubes are manufactured/"grown." Cool stuff, Karl!
Don't forget, CPUs are "grown" as well.
@@transtubular They're also not sold en-masse to the military and priced ludicrously high for civilians afaik
Stuff like this is why I gladly/full heartedly support this channel.
I love the 4 minutes of PVS-7 cope that takes place before any "testing."
Great video, as always very entertaining and informative!
6:48 I could smell the aged Volkswagon plastic as soon as you got into the car. Now I have a headache. 🤔😄
As someone who has definitely not violated any vehicle code and has only operated NV as a passenger, yeah the dash really fucks with nods. On some you can't even just pull fuses as the ECU thinks there are issues and either throws codes or in one case refused to start. Ended up taping over a lot of stuff just to make it more useful. On the plus side it does make it very easy to spot wildlife on forest roads way before you normally would. A lot of people go right to having IR lights on the vehicle and that is a good thing, but imo a lot of people will remember that active IR use may advertising your position to other NV users while in the shooting context and then immediately forget that in a transport one.
One difference that I see is that the percieved smoothness is better in the analog NVGs compared to the digital, as if watching 60fps compared to 30fps. Might be just due to the recording and IRL they may be identical, I don't know, but through the video it seems that way.
the night time desert looks downright beautiful through the opsin
Awesome video, loving the nightvision content :D
Glad you enjoy it!
Impressed with the digital quality
keep up good work man. Advancement in digital NVG gives me hope for relatively competitive and low price devices in the near future
Already have duals but i can see upgrading to this in the future. Very promising stuff.
Really well-done. Kind of shocked that digital NV isn't further along. Not that it doesn't seem perfectly capable for every application I can think of. Thanks for keeping it real. 👍👍👍
🙏🙏😎👍👍🍻 thank you very much! I couldn't tell whether there was latency or not. The purple trees are super cool.
Yeah, we really can’t, but Karl would have said if it was an issue for him.
Based on my lived NVG experience with PVS-14s, I’m sure the lack of depth perception is a bigger issue than a tiny bit of image “lag”.
I initially wondered if it because of the small screen on my tablet, but others seem to have also noticed - the digital image seems to have a deeper depth of field ( more of it is in sharp focus). Because of that, it seems like the drive with the digital unit was faster.
Small sensor means that depth of field for a given aperture will be greater. The same is true for cameras - "APS-C" sensors on cheaper cameras give greater DoF than on cameras with larger "full frame" sensors using the same lens. The sensor on the Opsin will be smaller than the photoreceptor on the II tube. The downside is greater noise due to smaller pixels.
This is interesting...and will be improved in years to come !
A decent experiment, but latency is measured in milliseconds; how many milliseconds does this unit take? It seems like without too much trouble one could rig up a measurement: set up the night vision goggles in daylight, except covered with something to block out most of the light (like welding glass, perhaps in multiple layers). Then film with a normal camera. Turn on a flashlight where both the normal camera and the NVGs can see it, and where the normal camera can see the NVG's screen. Then count frames between when the light turns on and when the NVGs show it turning on. (Set the normal camera to its highest frame rate for best time resolution.)
The virtual reality guys like their "motion-to-photon latency" to be 20 milliseconds or below; longer latency gives people a motion-sickness effect. NVGs might not have to do quite that well, but it is a similar environment.
Thats awesome your using a brainexploder mount, I used to watch and airsoft with Ivan all the time and love his 3d work
As a night-blind poor, i find this video intriguing. Especially if digital is at a more attainable cost
Super helpful. Digital looks great!
Glad it was helpful!
That digital image is pretty damn good
My pixel smartphone does the same thing as the Opsin, but to a MUCH smaller degree and with seconds of latency when I move the camera. However, it does amaze me when I point it at an area that looks almost pitch black to me, and I see a pretty decent image with color. It wasn't meant to be a night observation device, but I've actually used it as such in a pinch once when I forgot my flashlight. I wonder if it would be easy to fuse thermal with this in one dedicated unit. Best of both worlds. That, and swappable 18650s (or whatever battery tech is "the thing" right now) would be nice as well vs a proprietary pack.
Side by side footage 👍
A Thing! those are so cool!
I believe in this technology and want to see it mature.
This is a very practical test but it does have some issues.
Whats being recorded on the PVS-7 is a capture of the output. Whats being captured on the Opsin is what the camera sees, as opposed to what you the user see. (Directly writing to what i assume is an SD card as opposed to seeing it visualized on the screen)
I think a good alternative test to put all qualms aside would be a rabbit moving across quickly recorded with a high speed camera as your eye would see.
Love your content. It is enlightening as usual.
Interesting bit of knowledge for you and everyone here. The lag you're experiencing with the Opsin is likely measurably _less_ than the lag between the light hitting the back of your eye and your consciously recognizing it. See, the image from the eyes isn't sent to the "thinking" part of your brain. They are processed and washed a bit based on prior experience. These are then written to your short-term memory. At that point, the thinking part of your brain retrieves those memories and does its own processing. Which is one of the reasons a young child has trouble catching things. They haven't yet learned how to "see into the future." And also why two other identical people can watch the same event and see two different things.
Eh. Average gross visual reaction time is on the order of 250ms. Athletes and gamers who train/are selected for reaction times will creep down towards 150ms or below.
A 60hz refresh rate means a 16.6ms frame time, a 90hz refresh rate (which Sionyx advertises) is 11 ms. That stacks on top of whatever your reaction time is, if you're particularly quick that could be making you more than 10% slower. And only really refined video pipelines actually achieve zero overhead latency, even the sharpest gaming monitor setup will have another millisecond or two on top of the refresh rate, and bad systems (like the old Aurora) might have 20ms or more. If you have 40ms of latency between frame time and overhead that's a handicap on the order of 20% for someone with completely average reactions, which is huge.
Operator Drewski made a really good video about night/thermal vision.
Would love a deep dive video on your car- driving a 50 year ol VW must have a solid reasoning and some cool experiences behind it.
Vin wiki has a story about a cannonball run which people used night vision scopes on their car. Good info in that story. And how they used it. It would be nice to have an automated scope that could identify hazards for extreme distance.
vinwiki Here's how we made our car invisible to cops
Digital Night Vision will get a lot better from where it's at now. Current iteration products are simply using sensitive sensors with tuned ISO gain circuits not much different than existing mirror less cameras. Tesla's adventures into cameras for self driving showed that while color accuracy goes away in very low light situations, a useful image can be reconstructed for navigation purposes. To take advantage of very low light performance though, any DNV manufacturers are going to need to have their own signal processing.
Would have been nice to have a third video showing how dark it actually was when driving...
I tried. The regular camera was just darkness.
For me, footage from Opsin looks very much alike "night" scenes from old movies, recorded during the day through the filters.
Based on that comparison, i think that, the fact of having coloured image instead of monochrome, is way to much overlooked. I had way easier time to distinguish where the road goes at distance, because vegetation and road had different colours. Footage was also more crisp, like there is wider margin of focus, that camera can provide over the intensifier tube.
My thoughts are, the digital nvg can be much easier unified with thermal vision. Both system are based on digital cameras, so goggles can have bulit in nvg and thermal cams in front, displays at the back, in one slick housing. The computer unit can be moved to the back of the helmet (more powerful, to fight the latency problem, worsend by adding longer connection with cameras and displays), and the battery could be moved from helmet to the pouch on the plate carrier. I have feeling, that this setup could be more practical and modular.
The digital tech is getting better and better
The first time I drove with PVS-14s, they weren't working properly, and I could barely see. It was a miracle i didn't crash
I like the green phosphoric for what they do, but, the digital's, for me, are a better choice. The digital units seem to allow the batteries to last much longer. The PVS's units I have, maybe I can get 4 to 6 hours out of them of continuous on time. Now, In my opinion, the amount of "ON-TIME" or rather "ON-TIME/SHELF-LIFE" is a huge deal on the green phosphoric coating or whatever that coating is called.. The older they are, they less the sharpness is and intensity is. Granted, you can send them in, to have'em rebuilt or refurbished or recoated. and isn't that costly. Which is still way cheaper then buying a new set.. It is also important, WHEN NOT IN USE, install the lens covers, on both ends, the reticle ad objective sides. Even is the units are not powered to the on position, if the caps on the INTAKE side or objective side, light is still getting in, and using some of that shelf life of the coating, of course, not very quickly, as compared to being powered on, especially with sun light...
Please note, I am not an expert in this field. I am just following the instructions from the manufacturer upon paper instructions, and phone calls for service refurbishment. Those are the folks who know what they are talking about, and when you have spent some loot on their product, they gladly inform you on proper care for their product lines..
The digital units, lack the range compared to the green meanies, but, anything out past 500 to 750 yards, is solid for me, that means I have a change to get a head start at running away... lol... Price is another issue. the digital's are much cheaper.. It is also important that I note, I am not telling anybody which one to get or not get... There is Pro's and Con's of both. I will say this though, not having a set vs, having any brand or type is better then none at all.
For what it is worth, I kinda wish I had saved my money and just got the digital CMOS or DSLR chip set units instead of the green phosphor retired / used units from the Military Surplus...As that would have allowed me to afford more digital units, one for the bathroom, each bed room, each vehicle, etc...lol..
Lastly.. There is a newer set out there that only the US military is allowed to have at this time. I forget what they are called and all the fancy bells and whistle is has, but, a set of those can delineate the a thermal scale and mark a line around it if that feature is activated. Rumor has it, that this feature chews up the battery power, but, highlighting the critters you are hunting, while not blowing your eyes out, just cool as heck... I believe those newer units also have built in record and send feature, I do not know if it is a Wi-Fi thing or Networked to a Sincgar system? or on its own proprietary comm's system.. I don't know. I just know, I want to play with a set, but, something tells me, these units will exceed the last units in cost of well over the MSRP of $40K $5K to $10K used and will be WAY OVER THAT price scale...lol... NVG's with thermal constrasting, $$$$$$$$. Does anybody really need NODS or NVG's of any format? YES. because we can.... Because.... AMERICA ! ! ! ! ! !
One more lastly.. For you Californian's Pay close attention to your corrupted gun laws, or rather, anti-2 laws... Your rifle system, is not allowed to have night vision AND magnification mounted on the rifle at the same time. You can have one of the other, but not both mounted on the rail at the same time.. You can have your NV helmet mounted and a reticle or scope or red-dot and magnifier mounted on the rifle rail or 1913 PIC rail.
I mention that, as I have seen some cheaper night vision monocle PVS's out there, that comes with a mounting bracket of sorts, that would allow for such to a rifle's PIC rail... Don't do it, or at least educate yourself first. I do not know if there is any other state that has that restriction like that, I heard Connecticut also has that restriction too, but I have not taken the time to look it up to verify the validity of such. I am sorry. lazy I guess. Plus, I don't live there..Please feel free to correct any of my info, so I know better or the better way or correct info. You will not offend me, as I prefer being educated and not always the dumba$$ that I typically am. Plus, your correct info, can and often times helps others that didn't know to ask the oddity of questions CHEERS...
I just love Sionyx picture! I bet the color is ever better in real life. But in the video it looks like it's snowy white. But yet you can distinguish color and objects way better against classic green hue.
Definitely the future is for the digital.
Have you tried shooting at moving targets with the Opsin? would be an interesting comparison
He's done a spinner in the first video, if I recall.
Having the reduced glare and better color is a huge advantage in actually identifying what you're looking at, that alone makes digital NVGs an attractive option to me.
While the ospin may not be as good as a PVS-14 for SF door-kicking, combined with thermal optics, they would probably be excellent for night sentry duty.
Wow that opsin has a super crisp image. Thanks for the vid. My only little nitpick is that we, as viewers, will not be able to get the most true-to-life comparison here. Because TH-cam only can run 60fps max videos, and I think the opsin also runs at 60fps, so that image is, most likely, fairly accurate. But the practically infinite "framerate" of the analog tubes just can't be truly showcased on video. Now, 60fps is, generally, good enough. You can do things like play racing games, or first-person-shooters at 60fps no problem, so I would say that in 95% of situations the average user would be in, the quality modern digital would be up to the task. But, in a highly dynamic environment like combat, the fast-flicker of digital, rather than the real-time of analog, is going to be a liability. As digital gets better and better, that liability is shrinking, but I feel it's not entirely inconsequential..
But hey, that's just my two cents on the matter. I appreciate you putting out the content you do that gives your accurate and honest thoughts on various subject matter. You're incredibly informative and that is a benefit to all your viewers. Keep it up brother. Semper Fi
The 7 obviously has better amplification because you can see wary more stars. However, the opsin has the advantage in color and, it appears in this video, better focus on both up close and far away objects.
That's because the analog detector runs an avalanche detector, it's all or nothing. The digital has deeper/finer resolution and like you say better focus.
The footage from the Syonix Opsin certainly looks very nice from the comfort of my computer chair, compared to your PVS-7, but I can't help wondering if extended use might cause "simulator sickness" (or motion sickness) from the slight lag (which, of course, is impossible for watchers of the video to really feel) between movement and the screen updating.
I suspect that with digital night vision at least some of the latency is caused by the manufacturer trying to put too many "features" which are "hard-wired" into it and always using processing power, even when turned "off", such as various recording modes and image modes (making the image "look pretty" and/or imitating a microchannel plate style image) and also the support circuitry for the LCD eyepiece could be part of it, presuming at least some parts are COTS and not possible to manufacture in-house.
This might not seem connected, but apparently the early development of the Oculus (no suffix) HMD was mainly concerned with stripping-out processing done in the mini LCD monitors used in the eyepieces which caused noticeable lag between head movement and display update, so being able to manufacture an entire digital night vision device from video sensor chip to LCD display and integrate them as closely as possible (without having to "demanufacture" cameras and LCD screens into parts and then rebuilding them), with as little processing between each stage as possible seems like the big hurdle, but that would have to be assessed as to whether it's worth the cost of squeezing out that little bit more performance and if the market would bear the cost of doing that R&D in the final product, compared to microchannel plate based devices.
Nice
A better test would be to play catch at night.
I own a Opsin, and I have driven with it, with cars and with bicycles, for me it does not really make a difference. What I am thinking is that the Opsin is more sensitive to IR illuminators that analog ones, so far it was hard for me to find ones that are weak enough not to cause problems
Think digital NV for sure is the way to go especially considering it'll only keep improving. I'd be curious tho too if/how the potential latency/refresh rates might be perrcieved by someone prone to motion sickness? Like with how some people will get really nauseous while using a VR headset. Since from an usability perspective those don't seem to be an issue but I would be curious about the accessability aspects.
Ngl seeing the digital video alone made me uncomfortable. It looks unnatural compared to the analog counterpart, as if something isn’t right with the movement. Couldn’t imagine using it for more than a few minutes.
as a VR enthusiast, i can say, motion sickness is directly tied to the intensity of the experience, how well the experience is built, the hardware running it, and the amount of time you have in a headset. admittedly my tolerance is pretty high, but after an hour or so, i got to the point where i could do backflips in game, with my feet on the floor, while engaging targets, and barring serious hardware issues, 'normal' VR usage basically doesn't bother me.
I'm sure I'm not the only one who kinda wants a video just on the car.
th-cam.com/video/C37OAHao9AA/w-d-xo.html
Digital can also benefit from post processing, think your smart phone and the ability to enhance or create other effects to sharpen / image correct etc. I also think there is room for a dual nod setup that interlaces frames so you can get 120hz refresh rate with 2x 60hz units which would eliminate any arguments about latency.
In the demo I do see some of the "framiness" especially in the more bumpy parts but unless it gave me motion sickness I would be perfectly happy using them to drive and the clarity and detail was so much better than the analog.
Rolling shutter is going to be a thing that differentiates DNV quality. Some of the blur displayed is as a result of the time it takes for the sensor to be read between displayed frames.
I wonder if it would be possible to use mirrors for a periscope effect. Like the mirrors would exist in front of your eyes whike the actual machine sits up top. Theoretically that would mean you could have a shorter length from eye to the front. It might mean being able to get a cheek weld and using existing sights.
I think digital vision enhancement will not be a problem when they get actually large scale implemented because my money is that it wouldn't be a self-contained little monocular device. I see such devices being distributed along with other devices. So the helmet contains sensors and screens but all the other bits that are used for image processing are distributed around the helmet or if implemented with other things like communications, you might actually want to move most of the tech out of the helmet to somewhere else off the helmet to keep it light. I picture it as a sort of armored collar around the neck, so doubling as protection to some extent. That also moves heat generation out of a small enclosed piece on your face to a larger, easier to cool place AND gives more space for more powerful computing units that if not able to directly reduce the latency would be able to use the added processing power to basically DLSS predict what the next few frames would be.
Imagine a souped up smartphone being imbedded in your armoured collar that does image processing for not only night vision by augmented reality and additional communications. Add in swappable rechargable batteries with some hardline I/O ports for quick on-site data transfer and you got a winner. Right out of Ghost in the Shell just minus the net-jack to the cyberbrain.
And honestly, I think that little bit of latency really doesn't mater because the weakest link in that whole system is the bowl of tapioca pudding running a meat-mech that's using the kit.
So basically a digital gorget.
huh. foliage appears as a brighter white in the Opsin. so it sees near-infrared and is color-balanced around that. it should be very interesting to take a look at various clothing materials and colors through it.
Ahh beans, I saw this and thought to myself "Man, I should maybe see what it costs to get an Opsin" but then found that in Australia due to manufacturers policy changes they'll only sell it to government agencies now.... Lame
I noticed that too. There's always "rolling the dice" on an AliExpress knock-off😉
Is there problems with eye strain on the digital unit? Interesting video!
If i have a 3 fireteams to equip im running these hands down. The more youncan aqire the better.
Thumbs up.
The Opsin is really impressive. What's really frustrating is that you can't actually buy them here unless you're a government/law enforcement employee due to ITAR, like Gen3 tubes. 😑
I don't know where here is, but you can buy them in the US directly:
www.sionyx.com/products/opsin
@@InrangeTv UK. But it looks like it's the same in the rest of Europe, according to the official dealer list - they all state government/military/LEO only. I'm looking at the Aurora which is meant to be pretty good too, and is not restricted.
I talked to one of the Sionyx representatives at ENFORCE TAC earlier this year and they specifically mentioned that there are no ITAR (or other export restrictions) on the Opsin, since this is essentially just a digital camera. It might be a case of local laws (some countries restrict access to NVGs for civilians) or internal policies of the local distribution partners (like some companies only sell ballistic plates to GOV/LEO, although there are absolutely no laws restricting civilians from having them). If there are no local laws in the UK regulating civilian ownership, I'd suggest directly contacting the various European resellers and asking them. If there are no legal restrictions and this isn't a mandate from Sionyx themselves (which is possible, ENFORCE TAC is aimed at government organizations after all, so it's possible he was referring to "there wouldn't be any issues from the US side to sell this to your orgs here in Europe") there is a good chance one of them might sell you one.
Just buy direct. It's literally a photography device.
As long as your not known to your local intel office and you don't do stupid things with a device typically countries don't care.
I think the next step for digital night vision is stoping to be tubular layout.
The camera and screen part of digital night vision doesn't need to be inline.
I imagine a vr setup with two big sensors in the front that feed an image to the screen inside the visor.
Karl, thank you for that explanation and comparison to analogue and digital night vision. Two questions. 1. How do Graboids appear on either platform? 2. The Opsin appeared to be operating with the Fallout New Vegas filter. Is that an enhancement that can be purchased, or does it come with the standard setup? Cheers!
Cheers
I would think the limiting factor for the digital one would be the amount of power it can draw vs battery discharge, which will only get better as chips get more efficient.
Hi
Would be cool to know the light conditions in the night. Full moon, half or no moonlight at all etc
I have 7's and 14's and i always play with my 7's more i think its just the nostalgia and that green phosphor image
I've always wondered how much of an improvement could be had by making covers for your headlight that only allow IR light to pass. Yes, they would be visible but far less than white light and how much of an improvement in near 100% dark nights (eg. new moon, complete overcast and why not tree cover to boot).
I wonder how hard it would be to reconfigure the digital so that it output to a lighter eyepiece but with the optic mounted elsewhere, or even in a different angle to mitigate the cantilever issues with weight...
What dovetail adapter is that on your pvs7?
My question is does it work as an nvg device even if it needs an illuminator for walking or moving on foot if I need an illuminator like a gen 2 device is super bad conditions that's fine and battery life
Were the pvs7's out of focus or are they just that blurry? Only experience I have is with pvs5's and starlight scopes and I thought they were clearer than that.
Filming through analog night vision, at least with this brain exploder, isn't optimal.
If it had built in thermal with an overlay it would be near perfect.
Is there a minimum hz/fps? I have an aurora black unit and it tops out at 60fps
I really don't have $2500 for an opsin. I plant to augment my aurora black with a flir breach and that is also 60fps, but I don't have the $2500 to drop on a single unit atm
Opsin can do 30, 60, or 90 fps that you can change on the fly. Really comes down to what's your battery capacity, and what do you need to accomplish with the unit?
Or maybe I'm just wrong and a Sionyx shill, who knows.
This kinda reminds me of the LTT video comparing performance of esports player with different display framerates. Like, sure infinite FPS is better and zero latency is better, but you don't suddenly become disabled with 5ms or even 10ms latency.
Karl do you know if in the case of the Opsin the latency comes mostly from the display, the computer, the camera, all three ? I'm fully expecting and Oled 240fps whatever version to come out in a few years.
I think things become mostly usable once you are at 60hz (16ms refresh) with no overhead latency, and things really feel great once you get beyond 90hz (10ms refresh). Sionyx advertises a 90hz mode for the Opsin, but I don't know if there's more latency on top of that.
Was the latency noticeable and if so was there any cognitive correcting? I like digital, but I feel like I'm stuck where both current digital and analog are going to be outdated soon
The very first thought I had when I saw all the IR cameras on the exterior of the Apple Vision Pro was "this looks like the lowest latency highest resolution digital nightvison on the market"
Digital night vision is really cool, and as someone who has invested in analog tubes, I wonder how long before my investment will be an antique
Presumably you can kill the WiFi and such right? Could the unit’s gps or even digital signature be used to locate or track it? If so that be kind an uncool drawback if someone was searching for its electronic signature/fingerprint.
Gps reception is passive. Wifi is able to be turned on or off.
👍👍👍
I thought the digital was actually better in this situation, mostly because of how it dealt with light sources in the background.
It would've been better if you had a control (no NV view) next to the 2 you were testing. It's kind of hard to tell what the natural light state was in the comparison. Other than that, very interesting.
The regular camera was just a black screen.
Dumb question, but why didn't you hook up both NVGs attached to your head at the same time? You can't really see lag from the video without a reference to what is actually happening!
sionyx wins - image is soo much clearer, sharper and the color really adds a lot.
Was this on the fastest 90hz refresh mode that Sionyx advertises?
👍
I'm very colorblind but the digital one did look better.
Thank you Karl, I thought the digital image was more realistic and that the brain would better to be able to process the image.
Ive been dreaming of riding in the dark with some nvgs on my electric dirt bike
That lag is kinda concerning but isnt bad at slower speed
