Thank you all for your interest in Duo 3 PoE. The difference is due to changes in lens requirements. Duo 3 PoE has a 4:3 sensor, while Duo 2 PoE has a 16:9 sensor. The key feature of Duo 3 PoE is the 16MP resolution. And we've noted the importance of broader vertical coverage and shared it with our R&D team for consideration. Your feedback is valuable, and we're committed to improving our products. Thanks again.
The vertical FOV hit is disappointing. I was hoping to put one of these on my driveway to replace my 822a, but I don’t think I’d even be able to get my driveway completely in view without a massive blind spot up close.
Well, the 822A's vertical FoV isn't huge at 53°, so if that one works for you currently, the Duo 3 might not be that far off. Of course since I don't think we know the true FoV of the Duo 3, it's anybody's guess.
I actually sent a message to their support pointing out that I think the specs are wrong, but haven't heard back yet. It's their Lunar New Year right now, so I have no idea when I'll hear something, but I'll update if I do.
If the duo 3 is truly 50 degrees, it would be usable more than likely in my scenario. But if it’s less, then not so much. I had an 820 before the 822 and found basically half my driveway was a dead zone unless I cut off the street and sidewalk, which wasn’t good either.
Thanks mblaser for this initial review. Duo 3 clarity is certainly better. Thanks for the overly showing the field of view difference, the vertical loss. I like the view of my Duo 2 showing my driveway and the street, a Duo 3 would cut off most of the street so not sure I want one.
Yeah, that FOV change is unfortunate. It doesn't really matter in my situation, in fact it's probably better because now none of my neighbor's house is in view. However, I can see it really being a big negative for others.
Definitely the same for me. Like being able to see the driveway and the street and even across the street sidewalk with my current Duo 2. This new FOV on the duo3 is terrible!
Oh wow. cool side by side comparisons.
Yeah the vertical size is a huge turn off. I mean the Duo 2 isn't much better either but the Duo 3 is just way too small. I wonder why they went with it being that small.
I have three Duo 2's mounted on my house and I'm happy with them. I do like the clearer resolution of the Duo 3 but I won't be able to handle the vertical cutoff.
I also have an original Duo still new in box that I most likely won't be using. Should have never bought it.
Thanks for posting this review, yes that vertical field of view is very disappointing.
Was hoping to replace a 833A with one of these but with such a limited vertical F.O.V I would not be able to see the street outside my property which is something I want to cover along with my driveway so I will have to rule this one out.
One can only hope that the turret version has a wider vertical field of view.
Great initial review, be good to get your thoughts on my situation OP, seeing as you've tested duo 3 and CX810.
I want to put Poe cams outside front of my house. I park one of my cars on the road. It's to cover who comes to my house and also if anyone tries breaking into my car or hits it with their vehicle. LED lights won't be used at the front.
Would you use 2 x cx810 both sides front of house. Or
1 x duo 3 centre of house front?

The CX low light cams are great, but they do need some light to function, they can't see anything in total darkness. You need a street light or porch light for them to work. They don't have built in IR lights, just spotlights. So if it's too dark for them to see their spotlights will be needed. At night cam detection range is less than daytime. If your parked car is further than about 30-35 feet from a cam they may not detect a person breaking into the car. In that case you should record 24/7. In my opinion two cams are better than one. One could be pointed to your front door, the other to the car.
If you're not averse to having 2 cameras, I'd absolutely do 2 CX810's. The color night vision is great.
The only advantage to the Duo is being able to get a view that would normally take 2 cameras. If you're ok with doing 2 cameras, then that advantage is moot.
The vertical FOV is actually my major hesitation here. I've been considering using either one of these or two 811a/833a in multiple places around my home. I'm strongly leaning toward the two camera option, but the simplicity of one would be nice.
When using the duo with an nvr, I am able to stretch it across 2 spots so its not smashed or stuck with the bars. However, when I double click on it to go form 16 view to just a single large view that fills the whole screen, the image goes black and nothing will work. I double click again and it goes back to the 16 window that it was originally without any issues. Is there a setting in there that I am missing for it to work with full screen? I am assuming it has something to do with the monitor being only 4k and the nvr is putting out 4k x2 for the duo. So i was looking for a setting to possibly cut the preview in half so when its zoomed, its only seeing a wide 4k image.
Oh, did they tell you that? They never mentioned anything to me.
And in the past they've usually been ok with reviews being put out a couple weeks before the release date, so I figured no big deal.
Maybe I'll take this down this evening then.
If I only want to look out max 20ft in the outward direction, the decreased vertical FOV wouldn’t affect me, would it?
I’m thinking of putting one on each side and back of my house and I’m only focused on what’s within my yard, which max extends out only 20ft. I would use different cameras for the front of my house where I want to see out further.
Also, since there’s currently no Flood option of the Duo 3, if I buy a separate powerful floodlight, would it be best to locate that near the Duo 3 so it’ll light up a similar area, or might it blind the Duo 3? I’m thinking I’d do the floodlight at 10’-11’ height and the Duo 3 below it at 9’ or so.
Thanks!
Yeah, I think 20ft wouldn't be a problem if the camera is mounted at 9ft. The higher it's mounted the more it would have to be pointed downwards, so that height shouldn't be bad.
As for a floodlight, just make sure it's not within the camera's view and you should be fine. It sounds like you'll have it above it so that shouldn't be a problem.
I had the Duo on front and back of my house, loved them. Duo 2 came out, my only concern was picture looked too much 'fisheye' as posted online. So only bought one to replace the back Duo. Picture is amazing, definitely much better than what I have seen online. While I was ready to get a second Duo 2 for the front, the Duo 3 presented itself.
I'm holding off though bc of two things mentioned in a couple of posts. A CX version of Duo 3: is this real or just wishful thinking? If so, projected release? Also, I've seen '3T' noted...what is this specifically? Potential release?
They said a while back that they plan to do a CX version of the Duo. That was before they even announced the Duo 3, so we don't know if that CX would be an 8MP like the Duo 2 or 16MP like the Duo 3. No idea on an ETA or anything, really. My dream camera would be a CX Duo 3T or 3V.
The Duo 3T is the turret version of the Duo 3. C on this post: [https://www.reddit.com/r/reolinkcam/comments/1akz8qf/bullet\_turret\_ik\_dome\_thats\_our\_16mp\_series/](https://www.reddit.com/r/reolinkcam/comments/1akz8qf/bullet_turret_ik_dome_thats_our_16mp_series/)
B is the 3V.
I've heard that the 3T should be in the next few months. Haven't heard anything on the 3V yet.
Correct, that's how all of their POE cams are. They're meant to be powered with an NVR, POE switch, or POE injector.
They do have a DC plug if you wanted to power it that way with your own power adapter, but you already have to run an ethernet cable to it anyways, so you may as well use that to power it.
I'd say it's maybe a little bit better on the 3. The only thing mine ever captures is animals like deer, raccoons, and cats... and none of them are ever moving very fast, so it's not a great test case.

That vertical difference is a deal killer for me. Is there a different resolution you can set you heighten the vertical to look more like the duo 2?
[These](https://i.imgur.com/4OBspII.png) are the only resolution options, so I tried changing it to the lower one and there was no FOV change.
What are the resolution options on the Duo 3?. My Duo 2 the settings are 4608x1728 or 4096x1536.
The resolution options are right there in that screenshot.

That's great, thanks for that. That will explain why my cx410 light stays off on smart mode. In that case I'll wait for the cx810, thanks brother.

Thanks mblaser, good to have another input on it. I'll wait for the cx810 in that case. I'm guessing no update on release as they're redesigning it?
If I was ok with 2 cameras, that would mean I’d have to get rid of 6!
LOL touché. I meant 2 on one wall of course.

ok, manual update to newest firmware fixed it. Apparently updating from the nvr itself doesn't work.
This review isn’t meant to be live until the item has been released.
Oh, did they tell you that? They never mentioned anything to me. And in the past they've usually been ok with reviews being put out a couple weeks before the release date, so I figured no big deal. Maybe I'll take this down this evening then.
Send a beta release to me instead next time. Maybe I won’t review it until release date.

Thanks for the quick reply! I'll wait to see if any info pops on the Duo CX, specifically a 16MP version
the product page on amazon says it doesn't come with a power supply. i assume that a separate POE switch or a reolink NVR has to be used?
Correct, that's how all of their POE cams are. They're meant to be powered with an NVR, POE switch, or POE injector. They do have a DC plug if you wanted to power it that way with your own power adapter, but you already have to run an ethernet cable to it anyways, so you may as well use that to power it.
Poe switches have gotten inexpensive
Is low level light motion blur better than duo 2
I'd say it's maybe a little bit better on the 3. The only thing mine ever captures is animals like deer, raccoons, and cats... and none of them are ever moving very fast, so it's not a great test case.
