REOLINK CX810 ColorX PoE Camera, 4K UHD, True Color Night Vision, F1.0 Super Aperture, 1/1.8'' Image Sensor, HDR Technology, Person/Animal Detection, Spotlight & Siren Alarm, 2-Way Talk

I have used many security different cameras including Reolink and non-Reolink. Of all the cameras I have used to date I would rate the Reolink CX810 as the best one. In this review I am going to explain why. In addition, I am also going to explain a couple things that you should know to understand exactly the performance you can expect. I am not going to discuss the technical specifications of this camera. Instead I am going to use a number of different usage scenarios to show you the images the camera will produce. The first point I want to discuss is that this camera has low light technology. What I mean by this is that it will deliver true color even at night IN VERY LOW LIGHT SITUATIONS (no IR or light). All of the pictures/video in this review have the CX810 set up for 3840x2160 resolution using the H.265 protocol (lower bandwidth). The CX810 has 3000K lights (not UV) that will turn on when it detects motion to illuminate the area. In all the the pictures/video in this review I have disabled these lights. Because my camera is part of a security system I don't want the people to know they are being filmed so I have disabled them. The point being that whatever you see is based on whatever light is coming from somewhere else (more on this later). I am using Synology Surveillance Station which has both the CX410 and CX810 cameras in its compatible list (otherwise you have to use generic ONVIF). PIC1 (I have labeled each picture in the upper right corner because they don't always appear in the order I add them to the review) shows a daytime picture of my driveway/yard during the day during the summer. I think the color and clarity of this image is good. PIC2 and PIC3 are pictures taken at night when it is getting dark (although not completely) and dark. Pic2 was taken in the summer and the grass is very green in color. Note that this picture was taken at 8:14pm and it was starting to get dark (although not as dark as it is going to get a bit later). The proof that it is somewhat dark is that my solar light turned on (next to driveway and garage) and the neighbors lights on their garage are on. Because the camera is very sensitive these lights will "wash out" the areas around them. Compare PIC2 to PIC1 looking specifically at the neighbors garage and you will see what I am talking about. PIC3 was taken at 12:09AM (midnight) and it is as dark as it is going to get. One thing you need to understand is that this picture was taken during the winter so the yard is not as green as it was in the summer pictures. As I have shown in PIC2 and PIC3 the camera does a real good job as long as there is some light. PIC4 is a second CX810 I have showing my back porch. Note that you cannot see anything on the porch. Note that the lights in my neighbors yard appear to be very bright resulting in my back deck showing no detail. I wanted to be able to see my back deck. What I ended up with after some experimentation was to add a dusk to dawn light for my back porch. Because a bright light will "wash out" details (like I showed in PIC2) I put a piece of aluminum foil in the side of the light facing the camera (so the camera would not see it). PIC5 shows the results of adding the dusk to dawn light (note you can see the silvery aluminum foil blocking the direct light toward the camera). The light bulb in this light is a 40W equivalent LED bulb (it was the lowest wattage I could find). The 40W bulb completely lights up my back porch which is about 45 feet long and some of my back yard . I consider the image quality in this picture as good. I have also attached a video to this review. Since you can only add a single video this is actually a compilation of 3 different videos. The video was taken by the driveway camera which uses the available light from my neighbors. The reason I have added this video is to illustrate what I will call "ghosting". The first part of the video shows a fox moving across an area of flowers (this is winter so they are dormant) and then moves onto the driveway and stops. Thile the fox is moving across the flower area it appears to be somewhat transparent. The second part of the video shows a fox moving up toward the camera then across the driveway into the flower area. The ghosting occurs as the fox moves more quickly across the driveway. The third part of the video shows a cat that starts out on my stepping stones and walks across the driveway. In this segment the ghosting occurs as the cat walks across the driveway. If I had a light on (like on my back porch) then this ghosting would not appear. The ghosting only seems to appear in very low light situations and you have movement (remember I have no lighting in these images except for what the neighbors generate). I was able to generate these videos because the CX810 recognized not only movement (like a light moving across the yard due to a car driving by) but as an animal. I have videos of deer, coyote, fox, cat, rabbit, squirrel and birds which were detected as animals by the camera. I doubt that it detects them all but it does the best job of any camera I have owned up to this point. I chose not to use the lights on the camera which would eliminate the ghosting and generate better image quality. All of the other cameras I own have IR lights (not visible by human vision). I don't like the IR lights because they attract bugs which fly around the lights (are attracted by the IR) and then generate false motion detection. The CX810 low light technology allows me to not need the IR lights and eliminates this problem and gives me true color even in low light. If you are looking for a camera that will generate true color images even in very low light situations you should consider the Reolink CX810 (there is also a CX410 lower resolution). It will get the job done!

I have a couple of these for driveway and yard coverage. They're good, a little better than the 410 but overall similar and my review will reflect that. Pros: -Daytime image quality is excellent -Night vision is very clear with a bit of ambient light from driveway wall sconces for example -Mounts nicely and holds position when you tighten it down Cons: -Audio is overboosted or something and clips/distorts easily -While the image quality is great, the metering/dynamic range isn't, it overexposes light areas in direct sunlight when my darker cars are in frame. I've adjusted the image in the NVR to deliberately underexpose a bit during daytime to compensate for this. As with the 410, it would be nice if there was a mic gain setting in the NVR or app and there must not be a foam insert around the microphone or something because it is very susceptible to wind noise. It does seem to be better tuned for detection than the 410, though it is also in a different area so it might just be situational.

I’ve been using this color night vision camera for about six months now, and I’m genuinely impressed with the clarity it offers at night. Unlike the standard black-and-white infrared cameras, this one gives full-color footage even in low-light conditions, which makes it much easier to identify details like clothing colors or vehicles. Setup was straightforward — the app walked me through the process, and the camera synced with my system without much hassle. During the day, the image is sharp and clear, and even at night, the colors remain surprisingly vivid as long as there's some ambient light (like a porch light or street lamp). It’s not perfect in total darkness, Motion detection is responsive, and I haven’t had any false alerts so far. All in all, it’s a solid camera for the price, and the color night vision really does make a difference in home security footage. I’m happy with the purchase and would consider adding more to cover other areas.

La qualité d’image est correcte, elle fait bien le travail. Après un an d’utilisation régulière, je n’ai jamais eu de problème avec, elle est fiable. Son gros point fort, c’est clairement son grand capteur : la vision de nuit est vraiment meilleure que sur mes autres caméras. Elle capte beaucoup plus de lumière, donc on voit plus de détails quand il fait sombre. Très bon choix si la performance de nuit est importante pour vous.

Excellent night time colour camera which is my go-to camera for my reolink NVR because I can identify colours of clothes and cars easily at a 20m distance with minimal external light. Great build quality and easy to install over POE

The difference between this camera and my original standard grayed out night vision is night and day litterly. The night time picture is bright and colourful! I have ordered two more with a plan to replace my old reolink cameras.

The CX810 is confirmed as working with my older and now unsupported by Reolink RLN8-410-E NVR (hardware version # H3MB16) with the latest NVR firmware from 2021 and latest CX810 firmware (v3.1.0.4666) installed. My old NVR had trouble previewing this camera in split screen mode. To remedy, you need to click on another (older model) camera in your system and put it in full screen mode, and then unplug and replug the PoE cable of the CX810 in the back of the NVR. Then you wait for the CX810 to boot up (about 2 minutes). Finally, once the CX810 is booted up and running, you can switch to multi-cam split screen preview mode again and the CX810 will be displayed properly and working solid. The color image on this camera is amazing during the day and especially at night, much better than their other 4k cameras that I've had to date. I needed to crank down the contrast and saturation of the CX810 in my old NVR's settings to 90 (from 128 originally), as both of these were way too high and the image looked weird. After the adjustments, the image is now perfect. I'm so impressed with this camera that I will be buying another, especially since it is now 30% off. I will also invest in the latest model NVR as well in the near future, in order to be able to use the new features of the CX810 such as AI detection, HDR and spotlight control. My current (old) Reolink NVR does not have these options and all it does is display an image from the CX810 and record it to the HDD, which is "good enough" for now.
