- In this video we are reviewing the Reolink Duo, a Dual Lens camera that has two 4 megapixel image sensors in one camera body, giving you an incredibly wide field of view, as well as spot lights for colour night mode, local person and object detection and so many other nice features, but have their been any compromises made in order to make the Reolink Duo happen?

Were my expectations too high!? 😬
If your expectations where to high so where mine... I actually choose not to get this camera but 2 seperate camera's because that gives me more flexibility. If there would have been 1 camera feed/stream I would have gone for the Duo.
Absolutely not. I do not understand what is this product for. _Thanks for sharing your opinion, I agree 100% with you.
My expectations were EXACTLY the same. I even initially though they were going to use the sensors from the 810.
I was REALLY disappointed when I found out it reuses the surplus crap sensors from their, older, no longer really selling, cameras.
If those images were advertised from that camera: then no, failure to deliver
You could easily get 2 4k cams and fit them side to side and line up the images. This way would be much better if you are seeing 2 separate feeds on the dua. But if you can't get another cable through for whatever reason then maybe this duo has a place.
As far as I know Reolink solved the 2 separate image issue by software and now you can see only one image (stitched)
Solid review! The TH-camr in me is just geeking out over that sequence of starting with one image then panning out as you threw the ball. I should have done that. Lol.
Haha thanks Jeff, I could have spent all day trying to perfectly line up the image correctly with the correct distortion etc...had to call it a day at some point!
Great review! More of these please !
You got it 🙌
I think I would still prefer my separate views/cameras, especially with using the Birdseye view from Frigate where it displays the camera where motion was detected. And the fact that i get better resolution and probably more "focused" or increased IR/light per cam
Expected one large, great review.
Thanks friend!
Your dogs are very beautiful!!! 😊
I have the 810s as well, great camera.
One large combined image is much better, at least if the software could stitch it while displaying in the app would have been great.
I agree, way better!
I luv my Eufy S40 Solo cams definitely worth the money! Has a Built-in Solar panel an Everything works Flawlessly ' Battery percentage is Always 99-100%
Any chance you do an update to the DUO 2 which has a wider field of view, upgraded to 4K, and has 1 wide image like you where expecting.
Wall-E look-alike... Wall Eyed! I like it though, pretty cool.
Are you going to do a review of the duo 2?
Kinda expected 1 image as well. but as i had a case of 2 fhd cam's side by side looking at the same 21meter object left side to right, its OK. 1 cam, 1 less failure point.
Came for the camera, stayed for the dogs. 7/5, would recommend.
I expected a 'single image' at first, but thinking about it, playback would be a nightmare. Screens just aren't set up for that ratio. You'd end up with it being encoded as a 'normal' res with huge black bars top and bottom (and killing the resolution, and defeating the entire point) or encoding it at 5120x1440 and it being a pain to view. You'd either need a dualscreen setup (not useful for phones) or the player would need to handle panning (would probably be bespoke then and a pain to share the video).
A good compromise might have been 2 4:3 streams stitched into a single 8:3 video, that would fit fairly well into a 16:9 ratio (smaller bands at least?)
Hahaha thanks!
Sure but most clients and apps have the ability to zoom and pan around so shouldn't be much of an issue
I don’t think your expectations were too high. There are really good use cases for options to do both a stitched view and split.
The 2 separate lens are fine. But the motion sensor is my main focus as i use battery wifi cam's
I've just installed the Camera, and now on the app both cameras create one picture that you can zoom and pan around, and the downloaded video is one picture also. So everything that was being critiqued and criticized in this video has now been fixed
Did you have both lenses set to the highest resolution and frame rate please?
That mount really doesn't look solid - probably a lot of shaking and vibrations in the wind. That's a shame...
Yep it's really not, no idea why they changed it, the old one was almost perfect 🤷♂️
Expected one picture also. Guessing the old style mount isn't strong enough to hold the additional weight of the much larger camera. Wondering if the night image issue was caused by different background levels of light between the left and right cameras.
The old style mount handled more weight IMO, some of the optically zoom cameras were pretty heavy and it could hold those, this thing is really light
So basically, just buy 2 x 810's if you want that much coverage? This was a really helpful video in demonstrating the weaknesses/ limitations of the Duo, and that's without considering the fact that the output for the two sides don't match in terms of colours/ contrast.
I would say yes! And thanks, appreciate it!
To me, it solves a hardware issue. I'm sure people feel weird about putting multiple cameras side by side, pointing in different directions. Multiple cameras in one enclosure sounds OK to me. From your description I first was wondering if the two lenses pointed at the same spot (so you somehow get 'zoom' for a portion of the image)
This is exactly what I was thinking. It's two cameras in one, for one price! :-D
Well…. Looks like a swing and a miss…. I would have expected combined images. I think your right, looks like a software fix should be possible. I would like to see how long the battery last on that version.
Same here, I though was gonna be just 1 large panoramic image. This is just 2 cameras in a case.
Thanks for the video... I almost bought it thinking that it was one massive field of view but 2 independent cameras is a deal breaker. Thanks for this video
You're not alone. I completely agree with everything you've said. The build quality is very poor considering their other POE cameras are of a metal conduction. This camera wouldn't stand a chance if someone tried to vandalise it. The fact that you're not getting one panoramic camera feed is a huge disappointment and actually pretty misleading. You're much better off just installing two regular POE cameras next to each other than using this device at the moment.
The ability to have one giant image would be great. But it shouldn't be a deal breaker. this camera solves an issue with hardware where you need to have two cameras side by side to cover a large area. Also, this camera would best be used in detection zones with night time color turned on so that you can get physical descriptions, like color of clothes, hats, skin, etc., and then combining it with hi res 8-12MP low angle cameras in recognition & identification zones for facial and license plate identification.
no one camera is going to do it all. this is a great wide coverage detection camera. and the lack of being a singular image is only a minor inconvenience that has already been around. So at least the hardware side is solved.
Would have bought it right away if the two lenses were treated as one motion picture!
And I would be able to give it a strong recommendation!
Great review!
Just 2 questions. The right image seems much more detailed than the left one. Is it just my imagination or is there really such a noticeable difference between them?
And I noticed the left one is has "dual" in it's name where the right one carries "duel" in it. Who made that happy accident? 😄
Thanks! Do you mean on the large image? There may be a difference in the colour balance between images since they are independent sensors.
Haha happy accident!! 😅
@@EverythingSmartHome for example at 9:27, where you stiched the 2 images together, it seems as if the right image is much more detailed. I was wondering if it were actually more detailed or just a sort of optical illusion because of color differences.
I think I'll stick to my Dahua cameras that are two lenses in a small dome.
You say the wifi is limited to 15 FPS, but from my understanding, this is just the default. You can change it to run at 25 FPS just like the POE version. True or false?
TRUE.. 15 is the default on the WIFI but it can be changed in the settings.
On the left camera, it says "Dual Lens" and on the right camera, it says "Duel Lens". LOL
😂😂
How would you deal with such a wide, non standard, image? One feed would display with thick black bars.... They made the right choice here, i think.
With reolink duo 2 u can choose it to be stitched right?
No, it’s set that way by default. One large picture
I was about to pull the trigger on this but two separate images blew it for me. I wonder how Blue Iris would have handled this?
Check out the Duo 2 4K
After watching this, basically the device is the same as having 2 x 4MP cameras set up. Looks like the night vision issues are still not resolved either. It seems to be an issue with all Reolink cameras.
Thumbs up for the R32
two feeds? thats a fkn dealbreaker for me, i thougth they would process the video in this giant case to become one feed. well, maybe in a year or two...
FYI, this camera is just a fancy case that reuses the surplus internals from their older and no longer profitable 2K cameras.
The 810A dropped down to about 100 Euro. My recommendation is to just buy two and take the time to position them side by side.
Purchase the camera poe only and make sure you hook it to the Reolink nvr only and with the correct hardware. The wireless one is not worth it.
I understand your concern but I didn't actually needed one big feed. The two separate camera views are just fine for my needs. I basically just wanted two cameras mounted to one spot so this is just fine. I don't need to feed another ethernet cable which will be a nightmare in the location I have the cameras. Thanks for pointing out the motion of the mount, I'll have to be very careful before permanently mounting it, otherwise I'll see more of the neighbor more than our house!
Fair enough, your use case sounds good!
Exactly! And glad to see someone who can think for themselves rather then use someone else's thoughts entirely.
Don't get me wrong I absolutely enjoy the video and his point of view, but at the end of it it's just that, HIS point of view, HIS opinion, you must think about what it is YOU need. This works great in a large property, to cover a larger area and instead of having to place 4 cameras in different points 2 will do or even in a scenario where you have a bit larger area and you need two cameras to view the full area space from one end to the other, this will save you the trouble of having to run two separate cameras, cables, installation. You mention 15 fps is the max but that's just not true is it? That's just the standard, you can go in and change it your self correct? So much more I could get into but never mind.
As I stated never mind my disagreement, it's just that difference of opinion, I ver much enjoyed your great video! Thank you kindly for your hard work, it does not to go unappreciated from any of us, the viewers and subscribers of your channel 😊.
I agree with Island Capture. My house is in a large cul-de-sac and I like to keep an eye on things across the whole cul-de-sac. For the longest time I had two cameras with two feeds that I painstakingly angled apart from the other to make it look like one wide view. It took up two squares on my screen, but that was fine because the cul-de-sac was where all the action was. This double camera from Reolink is innovative and they are thinking outside the box. 🙂
That's a shame about how it works, it would cost dual licenses on synology surveillance station
I was expecting one stream
I understand Synology only requires one license since both cameras us the same IP address
i really don't see the benefit of this camera compared to 2 well placed normal ones after watching this and well you get a lot less flexibility with it ,the mic is impressive imo though although i have nothing to compare it to myself :)
I think it had a lot of potential
The camera should stitch the images together by default using firmware, it's ridiculous that you have to download separate images. Who thought that was a good idea?
Thinking about it more - wouldn't a single image break nearly everything in a workflow after you have a clip you want to deal with? You couldn't share the clips easily (you'd have to use a video editor) - a simple action like sharing a clip to someone's phone, putting on youtube/FB would be cumbersome. And then, Reolink would have to rewrite all their software. Any 3rd party stuff that isn't expecting such a weird resolution would break. Reolink's software team is already pretty lazy most of the time - I can't imagine them supporting it well. Camera outputs need to roughly match monitors/viewports, otherwise you're going to letterbox when you view it.
Most clients have the ability to "digitally" zoom and pan around, so wouldn't be too difficult
@@EverythingSmartHome what about the ones that don't? You really have it out for this camera lol.
15 fps on the wifi version isnt that good at all
How many calories did you expend running side-to-side for an entire 15' review?
I use my cameras with a synology surveillance station. If it is viewed as 2 separate cameras then I would have to pay for 2 camera license for 1 camera. That is a no go from the start. SAD
i think i would have expected a single image from the dual lense.. otherwise.. just buy 2 cameras.. and at least if 1 fails you can see from the other one.. (and pivot it around to cover the main area
Agreed!!
The idea in this camera is can effectively get two cameras with one connection and power source. Everyone is in a tizzy about not having the two images stitched together as one. I am assuming that capability will be coming. You certainly wont resolve that if you buy two separate cameras.
Boy please take a break and don't forget to breathe.
It’s a good concept that failed in execution. It needs better image sensors, more compact packaging, and a calibrated & stitched output that operates seamlessly across the FoV. If it had that, it would be worth almost twice their asking price of this unit.
Don’t like the vast amount of exposed cable . . . . Looks untidy and perfect for an intruder to cut and render camera useless
Yep agree, that is what was also better about the previous mount!
I cannot help myself but It looks hideous.
Can't wait for TH-camrs to stop making stupid faces on their thumbnails. Why do you guys do it????
Why do you think?
