Note: In this video I converted the 1/2.8" sensor to 9mm because.. well 1/2.8" = 9mm. Turns out that isn't true and the sensor is 5.89mm, because back in the day digital camera makers realized it would be hard to market such small sensors. To overcome this they adopted a system used for Vidicon tubes that is approximately 1.5x larger than the actual size of the sensor. If you're a camera nerd here is a paper about how all of this works: dougkerr.net/RDP/RDP_S08_Sensor_Size_V01.pdf

That was a fascinating read. I’ve been taking an interest in digital photography recently and hadn’t seen any satisfactory explanation of the naming of sensor sizes before this read! Thanks for sharing!!!
Thanks for this update - this hits my nerve a little as MKBHD did the same mistake. LOL
Also a full frame sensor isn't 35mm across. It's just called 35mm because on a 135 film roll the film is 35mm film wide (due to the perforations). Full frame is actually 36mm x 24mm (about 43mm diagonally)
How does this compare to a Logitech Brio 4K. Afaik it's the only similar webcam
Wait, it says in the abstract: "We often find the size of sensors of “compact” digital cameras described with a notation such as 1/2.8” (which refers to a sensor size of about 0.19” × 0.14”)."
0.19 * 25,4 mm (1 inch) = 4,826 mm as width
0,14 * 25,4 mm (1 inch) = 3,556 mm as height
sqrt(width^2+height^2) = 5,9946… as diagonal
Where did you get 5,89mm from? Did my maths skills leave me again? 😦
*Edit*: Going down the rabbit hole of these 1/…" sensor sizes I found out that … … It's complete and utter BS, and every manufacturer just says whatever the f- they want, and it makes no sense whatsoever. Nice 🙄
LTT should do a massive review of webcams, like best ones you can buy for any budget, and a guide for getting best performance.
Here! Here!
Yes yes they should
Just watch EposVox. You'll find each and every webcam there is
Great idea!
@@camtono I have a decent cam, just feel this is become an increasingly important part of everyone's lives, and LTT would be smart to share their input with a focus on webcams only.
Was definitely expecting this to be better considering the price and size
@@anilkumawat4121 I did, and i agree, quite underwhelming for the price and size. My smartphone can do better with a much smaller camera.
@@anilkumawat4121 i did, the resolution bump was nice but the dynamic range isn’t great
@@TheGokki can't argue woth that one 😅
@@CalmConcept yes you are right, i thought you left rhw video in between that's why i commented that. 😅
Agreed. I barely see an upgrade here.
It should be compared to the Logitech Brio, not a laptop webcam.
The Logitech Bro cam? Is it the number one cam for bros?
@@CasepbX Read again.
@@Z3t487 original comment says edited, they clearly fixed it after they replied smartass
It was always Brio, I edited the "to" because I accidentally made it "top".
@@Slembilbong No man, it said Brio...
I'll be honest, this doesn't really look good for $200
is it me or was it really jittery when he switched to 4k? like someone just suddenly took off the stabilisation or something, made my head hurt.
Yeah especially when you can get a random phone and use its camera. Or even go the DSLR route.
dont forget guys that youtube compresses the video during upload so the quality of the cam should be higher in the actual stream. esspecially if they used a capture software to get the footage off the laptop this isnt accuate to the quality.
@@kalanivalentine yeah the video is at 480p
@@kalanivalentine exactly, but i m still kind of underwhelmed by the camera
Oh boy, this is going to look AMAZING once it's downscaled to 3.5 Mbps by Teams and displayed in 1/16th the size of my monitor.
Everyone will be so impressed.
the "explosure priority" kinda made me giggle :))
2:27 "...the *more bigger* the better" Alex Clark, 2021.
😏😏
Yeah...that one hurt.
Considering that Alex is into mechanical engineering I'm guessing that's an AvE reference.
it's also a jab at a poorly worded Apple presentation from years ago where they stated "Bigger Pixels = Better image" without going into WHY... which instantly threw off a lot of uninformed press.
Thats what he said
Moral of the story
Just get a used old DSLR
i've been looking into this and from what I can tell most if not all DSLR makers have an application they make for windows where you can use it to turn your DSLR into a webcam.
@@TjPhysicist just get a cheap hdmi capture card :D
Better yet get an Action Camera like the Insta360 or an older Mirrorless Panasonic or Sony and set it up for 1000x better look for not that much more money
Or use a medium range android phone. That webcam is not even close, in terms of quality image, of a 200 usd pocket camera from 8 years ago (thinkin in my canon g16).
Not all of them have clean HDMI out, or video out over USB (My old Canon 600D doesn't). But I have been using my GoPro with an HDMI capture dongle, works quite well, but battery life is a pain, and it likes getting hot.
shouldn’t it be „Exposure priority“? Explosure for sure would be interesting too though…
was about to react to it too :p
What does explosure mean? is a joke? non native speaker.
@@Z3t487 yeah its a joke ;)
(Insert Jay's iFixit EXPLOSION)
@@Z3t487 basically a freudian slip between 'exposure' and 'explosion', creating 'explosure' ;)
Webcam manufacturers will never learn how to make good looking cams. I'm fully convinced
The only one that I really like is the ancient iSight camera Apple did years ago. It’s 480p but it looks amazing. This one is quite the copy of that Webcam btw. Same form but with a different finish
try the Razer Kiyo Pro Ultra...
thats a literal CCTV camera my guy, it shouldnt be a webcam
The Starvis sensor is now being used in dashcams and it makes a *big* difference both in readability and esp low-light. I wonder if you could use the dashcams as webcams?? They're half the price. No "following" features, tho.
@@TheJohn8765 you can just use Nvidia Broadcast for that sort of thing, it works way better anyways
I thought it was the Razer Nommo in the thumbnail
@@TheJohn8765 Yes you can. Usually most cheap action cams and dashcam can transmit video over usb to be used as a webcam.
1/2.8" sensor ain't that big. A Galaxy S6 from 2015 has a bigger sensor than that. Considering the body size, I'd expect a 1/1.7" sensor or bigger to fit in there.
lol, when i saw cmos i thought it would be way over an inch size. That is hugely disappointing
6:52, Sony sensor magenta shift. Classic.
Looks like an old Apple FireWire iSight camera 😉
I had the same thought, I actually have one of those webcams. The image quality was absolutely crap though, especially for a premium product with Firewire.
@@anlumo1 For the times it was actually not so bad, compared to todays standarts it's a joke though. On the other hand, one twist on the Iris ring and your inner nerd smiles and everything about the picture quality is not an issue anymore 😉
i have 2 BRIO's i use for livestreaming, comparing the Dell one to those would have made a lot more sense for me. I don't see why they would compare it to something like a laptop webcam that's integrated. It has different purposes.
Because it's not an LTT review, but a shortcircuit video
Alex has no idea about anything computer related. if you have basic knowledge of laptops or cameras his reviews are really hard to watch.
This isn't a review. It's on Short Circuit.
@@Alexei_Drekker doesn't matter where it is posted. The dude is reviewing the product from his point of view.
@@PO0YA He clearly isn't. Watch the video. A review will always be marked as such. Watch the other short circuit videos.
1/2.8" sensor is still the same sensor size as most mobile phone cameras.
I think I should just buy a phone and use it's rear camera as a webcam
@@kientrungmai5598 yeah, I do exactly that. Works just fine.
Droidcam pro coasts only 5$
I think most smartphone sensors nowadays range from 1/1.12" (mi 11 ultra) to 1/2.0" (typical cheapo ones), and Leica and Sharp are also gonna release the 1" one
@@kientrungmai5598 I do that, but sometimes you may also need your smartphones ready while in zoom
@@RamkrishanYT Exactly. I retired my Oneplus 6T when i got my s20, now I use the 6T as a webcam, works great
I've totally done an entire review of a 4K meeting room camera and realised in post, that I only had it set to 1080...
The webcam looks like it has fixed focus (or it just has horrible autofocus), since Alex looked mildly out of focus for the entire test.
I dislike that most webcams these days don't have manual focus lenses. 99% of the time a person is sitting a fixed distance from the camera - or showing something up close in macro shots
Don't forget the optical quality of the glass tends to be bad in webcams, even high end ones
@@christopherjc54 What's even more infuriating is that the fact that the Dell webcam CAN be fixed focus implies that its depth of field is actually quite deep, a.k.a. its light gathering abilities are actually not that good. (It may have a large sensor, but if the lens has a narrow aperture, you cancel out the benefits of a a large sensor.)
"Explosure priority"? At last, a webcam I can use for filming myself in front of explosions!
They really REALLY REALLY need to have their camera expert handle these things and upload at 60fps so we can actually see the difference.
All webcams are terrible at 60fps. The sensors are too small to allow enough light in at 60fps. I've never found the benefit of 60fps to exceed the loss in image quality. 60fps should be reserves for dslr or mirrorless.
linus said (in a wan show) they would probably never upload/shoot in 60fps bc a lot of the camera crew would quit
Everytime he called it a dslr sensor, I died inside
Yeah, not a dslr sensor for sure.
If you google the sensor, Sony themselves redirect you to their CCTV line of sensors.
It's literally a security camera chip (sure a higher end one) inside a metal tube.
@@annekedebruyn7797 For sure, IMX274 points towards a variety of security devices and in some cases digital microsopes; the price point sure lines up too!
@@chaozbanditx Another comment said that it's the same as in a dashcam. And the dashcam was cheaper lol
But without some of the features.
probably the most excited i've ever seen anyone be over a webcam
'Dell Ultrasharp Webcam' is probably the best naming scheme in their lineup(not the monitors)
As a person with a darker complexion, I would love to see the exposure performance when framing someone with a darker complexion. Most cameras tend to underexpose for my face. Though the HDR performance of this camera seems promising.
I thought they were the Razer Nomo speakers until I read the title
ShortCircuit, I love your channel so much, I just had to subscribe!
Its design really reminds me ancient Apple external firewire iSight camera (which was a beauty, but 640x480).
So is all of the stuff happening with the dell software ? It would have been good if you showed how it would work where no software is installed (which is how most work laptops would work), and also how does this compare to the Logitech Brio
“A bit out of the budget for most people”, Understatement of 2021.
That lens cover is so clean! I’ll have to see if I can turn a magnet into a cover on my current camera
Looks cool but, I don't need 4K. What Apple iSight Cam style options are out there in white or silver to magnetic ontop of Apple Cinema Display?
What's up with all the recent Dell spotlights? LMG taking what they can get is fine, but I'm surprised Dell is still sending out garbage to them after being called out for borderline scamming them.
All business not personal
they were scamming them lol, should be thankful for the free undercover consumer action. that being said, different business units, marketing contacts, etc plus the subs...if it was a small channel maybe blackballed, not ltt
But they just scammed them with their personal computer selling department. Like one thing is bad so we boycott them completely? They can still review the products because that's different Dell right??
@@xvsun thats... not what he said
1/2.8 Inch sensor isn't equivalent to the metric system and is actually it's equivalences to old Vidicon tv camera tube (Which goes by 2/3 ratios)
1 inch type sensor is actually 16mm and not 25.4mm. And different Camera manufactures have different diagonals.
How does it compare to the Logitech brio 4K webcam? I bought that one about a month ago and I’m wondering if I probably should’ve held off until now.
I'm interested just for face tracking for animation like Vtube Studio. Do you know if this works exactly like the iphone camera with tongue and that stuff?
Would love to see a comparison between the avermedia PW513
I agree. This thing should be compared to cameras in the same class: pw513, kiyo pro, and brio.
I guess that digital zoom was made with the 4k in mind.
Do you have to install software? If I buy it for my work laptop where I can't install stuff is it worth doing?
I have a question, what will the web cam look like with an elgato camcorder usb drive thingy
I wondered why the Dell looked so much like the built in aside from color. Bitrate, resolution and framerate are the only things that ever matter in my experience, much less exposure, at least with actual webcams. I just use a 1080p Logitech I got for under 30 bucks used from Goodwill. Great way to get better than most for super cheap. Then just get a ring light or a lamp with a grocery bag over it like me (safely lol)
I believe BSI has been in wide use since at least the iPhone 4 times. 1/2.8" sensor is nothing to write home about either relative to what modern phones have today.
I've done a ton of research into deciding which webcam to get. I landed on the Nexigo N660P. It does a solid job, is 1080p 60fps. Lucked out and got it for $22 off Amazon renewed (because it's white, but a bit of paint fixes that.) A more budget contender is the Aukey webcam. It's like $27 on their site or Walmart. The only issue is the FOV is huge so you'll need to use OBS to zoom in a bit (which does lose a bit of image quality but it's fine.)
I'm convinced that anything beyond that $55 model of webcam is a complete waste of money. It gives solid performance with a reasonable footprint and it always just works. If you want to go higher end then get a cheap DSLR and deal with setting that up. The $200 webcams are complete nonsense.
One thing to note is that you need lighting. Every webcam will look garbage if you are using it in a dungeon. A monitor mounted light bar works great for this and is a very useful addition to any desk.
My 6 y/o $50 webcam can do the automatic zoom and tracking as good as this brand new one.
I'm impressed by the low-light performance of this one, but I don't know if it is $200 worth. Do they do face detect to set the exposure?
Yes. I want a surveillance camera on my desk!
I has a magnetic cover?!
This is the best picture quality you'll ever get without buying a DSLR camera and a capture card. Bravo, Dell, you've made something incredible.
Yes, I need that for my online classes
(First parts of the video)
Me on my 4K monitor: Are you sure you're shooting with the webcam in 4K mode?
(Andy checking Alex's settings)
Me: LOL thanks Andy!
Why would I want anyone to see me in 4K though?
How else you gonna please your onlyfans tho?
@@AndreiTache nobody wanna see my onlyfans even if i pay them
the Sony Starvis sensor is actually an outdated sensor technology cut to a different dimension, so although nice it is not _that_ impressive.
But still it has the potential of giving a better and more consistent image than most webcams out there.
Thumbnail had me fooled there for a second, thought the camera was huge af
Damn, this just shows how awesome are the cameras you use for filming.
Dell doesn't even say it's a DSLR sensor, why the hell would you say that.
At the very least learn some body language, thats why your stuck watching LTT videos by yourself
Found it weird too. Like he is quoting "DSLR" but didn't see them saying it. Also that's not how DSLR works.
All I want is a HD/FHD high framerate webcam.
Use your phone
@@jo_naash this. Or an used DSLR
get a gopro and a camlink
That segue to sponsor was great
Can someone tell me what his "main camera" is for this shoot? The difference is massive.
from when you started recording on the web cam I thought it looked kind of crappy for 4k. lol
6:35 im guessing you were typing explosion or something
do you know who to change the mirror image?...
So it's an up to date iSight camera. Construction, form factor and magnets and all. Nice
I'm sad that my phone costs about the same, has a bigger sensor and an entire phone attached to it...
Lol I guess at least the webcam has Windows hello
Look up "Iriun Webcam" ;)
You can easily use your phone as a webcam :)
Edit: Typo
@@kuhantilope8970 oh I know. There are many solutions for this. I'm just kind of shocked that this product exists... Not amazing value unless you want that face recognition.
@@Jackofafewtrades Yea it's shit :D
The "face recognition" is bad too. You can get a way better functioning one in the Nvidia Broadcast App :D
@@kuhantilope8970 does that one work with any webcam? could i do windows recognition with it?
@@litapd311 Windows recognition?
Yea, it works with any webcam.
But it could be that you need an NVidia graphics card, but I'm not sure 🤷♂
I must be getting old...the XPS webcam looked fine to me lol
Compared to this dedicated webcam it looked totally fine
I don't understand LTT and their reviews of webcams/mics on laptops. Whenever they say something is good or bad, it's a complete 180 of what's going on.
Washed out, blurry picture, and sounds like you're talking into a shoe "100% 5 stars best webcam/mic ever"
Nice contrast, sharp picture, sounds like you're nearly talking to a person IRL "0% 0 stars complete shite, laptop from above example is way better"
Ok, so its not just me...thought I'd have to go get my eyes checked or something...
To play devils advocate, I think Alex was still thinking of the older XPS 15 with the webcam under the screen, which are attrocious, and then didn't actually look at the quality of this newer XPS with a considerably better webcam while using it. I suspect that when presenting at LMG, your mind is completely occupied with doing a professional presentation, and not so much with what's actually in front of you
cant wait to test out that "expLosure priority"!
gotta use a couple a these for robot eyes
Seeing the new shirt on Alex made me think. Honestly the LTT shirt I want the most is the old classic Linus Tech Tips shirt that was in the geek squad style. My brother supposedly got it for me for my birthday back when it was available but he either never confirmed the order or it got majorly lost in shipping.
Now all I need is a _4K_ internet connection,
and a job
"The more bigger, the better," indeed.
Would like to see a proper comparison of this vs other webcams on the main LTT channel. This seems like the webcam so many of us have been waiting so long for.
Idk. I don't see anything compelling over Avermedia PW513 or Kiyo Pro. However, this review was pretty high-level.
It would be a great thing for short circuit for sure.
Not sure a whole ltt vid would be a thing unless it was a big roundup.
Maybe premier a few top rated webcams here and do a top ten on ltt?
It would be a nice guide for folks that need an upgrade and aren’t sure where to look
Can I get a 240p webcam so I can actually look good?
Buy makeup even if you are a boy.
You can just set your webcam to only stream 240p if that is your forte.
What's the point of 4k Webcam if most people stream at 1080p?
streaming i think
With the follow function it makes sense. So you crop the image to where the person sits.but I must say it looks crap.
@Isaaq If you want to future proof for high quality streams you don't use a webcam.
it's not 4K. It crops 1080p out of 4K to have that tracking
what's the point of a 4k webcam which looks worse than my 3 year old phones 1080p camera?
I currently have a 4K Hudly webcam and that seems comparable but it definitely struggles with exposure but this thing seems great at that
Short and sweet. You guys rock
Actually the 1080p looks like more a 720p, and that 4k like 1080p.
Me who is watching at 240p: They are all the same
For these webcam reviews, it would be good if you also did a quick segment with a typical home office lighting scenario.
you should show this in a real-world scenario since a movie set will always look good :)
4K that looks like 1080p .... yea good job Dell .....
More like 360p. No joke I thought TH-cam was using 360p or 480p but no. I was watching in 4K. (I was just listening before they showed the actual image)
how about i use a $100 android phone with 4k camera as my webcam?
I just bought a Sony camcorder (300$ new, i got it used for 80$) and a cheapo 20$ hdmi capture stick and it's amazing compared to my Logitech C920 (which is still around 80$).
As you mentioned, a phone is a great webcam, too.
Tl;Dr: if you need a good webcam, don't buy a webcam
@@WiboN I've got a spare galaxy s7. How would I go about using it as a webcam? It would probably be better than my 720p $10 Logitech webcam lol
@@jamesdillonmccracken easiest way is to use droid cam on the phone and computer. Slightly more complicated but more flexible way is to us ipcam eith an ip cam grabber program on the computer.
Remember to charge the phone. Streaming the camera feed empties the battery fast af.
Cool the phone if necessary.
how would this camera do with a green screen on obs?
I wish you could have tested the walk away feature and Windows Hello
2002 Apple called they want their iSight design back.
If a girl has a 4k webcam in a zoom class I'd be a little sus ngl👀.
took me a second but i got it XD XD
gotta make those 200$ worth it i guess...
Edit: if your teacher has a 4k webcam, that is wayyyy more sus
how much would it cost to get a second a 1080p dslr/camcorder and use that as a webcam?
How does it compare with avermedia's webcam?
I bet that once the resolution stepped up to 4k, the fancy follow and zoom function breaks. Standard practice is shoot in 4k, then zoom in post since it's pushed out in 1080p. That fancy setting does the same with it's 4k sensor when you are using it in 1080p.
What was teh microphone like? Did we test that? Windows Hello is a nice bonus. A lot of cameras with it seem to be around £200 (or are potatoes for £50)
but what's the point if it will look like crap on teams/zoom anyways because of compression?
Right on time looking for my Webcam. Currently using my phone as a webcam
You won't find a better webcam unless you use a DSLR or point and shoot with clean HDMI output
Would be nice to have a webcam roundup on the LTT channel.
In case of DELL Ultra 4k webcam: I have noticed that in HDR mode the picture quality goes down in comparison with HDR off (gets more cubics and looks low quality). I have noticed it on video here and personally testing it. Any explanation for it. Can it be improved?
40 seconds of 4K footage, Alex being Alex.. i guess it makes him feel wierd..
How does the Windows Hello functionality stack up against the Brio?
windows hello in laptop doesnt have two sensors, there an IR emitter that will turn on.The IR light will light up our face just like the iphone video which showed their face id.
Sorry if im wrong. This is what i know from my experience with a windows hello laptop that i own.
man this is gonna be great for apps that downscale all video to 720p or facecams that take a small corner of game streams
How does this webcam compare to the Opal C1?
Does this webcam offer 60fps in 1080p? The Dell website only talks about how it is 4k@60, I would really like to use it, but I´d rather have 1080p@60 if possible
Great Review. What I expect for tech tests.
Someone intelligent please tell which is better among this and logitech c922 pro?
I'm using my phone on a mount as a webcam look pretty smooth and happy with the results.
Interesting form factor, I'm sure we're going to see these quite often in hospital emergency rooms
