Review: Great camera for the price but with caveats - Get it for $109 and the price is right. You have to understand that while reolink makes a solid product they are different than your other security camera offerings. Imo reolink offers a reliable and quality product that is aimed to simplify the user experience. You're not going to find a ton of settings to tweak you're going to get the basics and the camera is going to do what it's advertised to do. It will run 4k and good bitrate with low latency and if optimized correctly , no dropped frames. If you only need a clear image with low light this is a great bang for buck offering. My other cameras that do this (and have multiple high resolutions across multiple sub streams and more options cost twice as much as least. But again for the price and the use case this is a great camera just know the limitations). For example shutter, exposure , gain etc you won't get that fine granular control you might expect from cameras like dahua/empiretech, amcrest, hikvision etc. If you're running an nvr such as frigate like I am you're going to be limited compared to other offerings. That's not to say this camera isn't good, it's good for what it is aimed to provide, a low light color image at an affordable price. So for me this particular camera was purchased for a section of the home to monitor an 84 year old with a hip and c1 fracture in the neck. I purchased this camera because I needed best bang for the buck for day and night clarity without creepy infrared glow during the night and this camera delivers a crystal clear pic during the day albeit some hard to tune white light balance (lack of control) and a reasonably clear nightine image with only a tiny nightlight on in the room (pretty phenomenal) and since reolink only offers 640x360 I had to manage my expectations in regard to face recognition for my automations and thus I have utilized the main stream for live view and detect (1600x900) In the frigate config and the sub stream for recording (I don't need hi res recordings from this particular camera) so for my use case this worked out. I did tinker a bit with the cameras onboard ai/detect features and compared to frigate they are laughable. Home assistant is also a great pairing with this camera due to great Intergration support which at the least when combined with frigate will give you control over fully off led lamp Motion automations to fire like they should unlike the app which does provide this but with the exception of the led always being on. Not good if you don't like bugs. So, if you need a great color low light camera without infrared, with minimal control but easy to setup and without multiple or higher res sub streams then 100% this is a great but for the price but if you need more control and features there are much better options out there empiretech t54ir is a fantastic camera and their full color model is excellent but be prepared to pay twice as much as this easy to setup low light 4k camera. The cx820 is a solid buy as long as you know what you are getting and what you won't get.
Review: Overall works bout flawless - From previous models that I purchased, or the same brand this does have a talk to option. And works solidly well from video to audio. No known issues with this for its specifications. Reolink has very good security cameras bout the best overall. And this being poe it does auto updates now connected with the nvr also on the reolink app through phones and tablets.

### ⭐⭐⭐⭐⭐ Love the CX line of Reolink Cameras
*by R***Y on December 2, 2025*

I originally purchased two of Reolink's RLC810 cameras, connected to a Reolink NVR via ethernet cables. Great daytime video, but the IR video at night was obviously not in color, not all that bright, and they attracted flying insects. I ended up replacing those two cameras with CX810 bullet style cameras, and the difference was amazing. Nighttime pretty much changes to daytime because ambient lighting provides enough light that the spotlights can be turned off and the color video is still excellent. I just purchased the CX820 camera for my garage, and it works great. Same lens, etc. as the CX810, just a different style of camera. Because the garage is very dark at night, I set up the spotlights to come on at night if the camera detects motion. 93 degree horizontal coverage. If you're shopping for relatively inexpensive security cameras that work great, you won't be disappointed with any of Reolink's CX line of cameras.
