REOLINK CX820 ColorX PoE Security Camera, 4K UHD, True Color Night Vision, F1.0 Super Aperture, 1/1.8'' Image Sensor, HDR Technology, Person/Vehicle/Animal Detection, Spotlight & Siren Alarm

Quality of the video at night is amazing. I have starlight cameras also and color x beats them easily. Build quality is great. The form factor is great to use it on the corners of the house under the soffit. No more filming spiders and mosquitos as it does not use ir and i dont even have to use spotlight. Also have the cx410 that i think has arguably better performance but is a bullet and is only 2k. I will love a duo or trackmix with this color x tech , will buy them on a instant. I think that would be the logical upgrade. Ideal world camera A 16 mp trackmix with colorx and a 6x optical zoom.

This is a great little camera. I wish Reolink would make all of their cameras color CX, especially the TracMix pan cameras! This camera picks up color very well at night, especially if you have subtle, low light, landscape lighting. This is a solid camera.I was so sick of my Wi-Fi Wyze cameras never connecting or missing activity. It doesn't do a person any good if they hear something outside and the camera will not connect. Not the case with these cameras because they are directly connected to the router and NVR system. It's almost an instant connection with the phone app!Having a solid connection via POE and a NVR is fantastic. No problems with connection and no problems with missing event recordings. The phone app is great (could use some improvement in functionality such as a setting to temporarily turn off notifications for 30, 60, or 90 minutes.)I am so glad I switched over to Reolink.

The image quality day and night is amazing! Their best single non-ptz camera to date! Highly recommend.

This camera has excellent picture quality, color accuracy, motion detection, easy setup,

Excelente cámara

(Note: my first rating of this particular camera was one star since it didn't work, but due to Reolink's excellent customer service regarding the problem, i changed the rating to FIVE stars). As can be expected, I was disappointed with the camera not working and I had to return it....BUT....with my faith in Reolink, after the camera was returned (with no problems..), I immediately purchased a more expensive "Wired Trackmix Wifi" camera and it is absolutely PHENOMINAL! I'm LOVING the Reolink Android app, too! The customer service response is MOST EXCELLENT compared to SV3C customer assistance taking 5-6 days or longer for replies! I have already left an exemplary review of the trackmix camera on Amazon and intend on building my future security system with Reolink and junking my SV3C garbage. THANK YOU Reolink!!! ❤️❤️❤️

So this review is perhaps a bit premature because I have not been able to mount the camera in the intended location as of yet, but I have been testing it for a week to make sure it works and meets my needs. Which I'm happy to report, it does. But it's not perfect.First of all, the image quality is very good, and the low light performance is excellent. It's been running in a dimly-lit room with a red LED at the lowest power the only illumination, and yet the image remains very clear and well lit; as one would expect, though, there are some artifacts as a necessary result of the very high ISO, like some ghosting with moving objects from the lower framerate. It's only a minor complaint though, as I said the image is great. Although if you're going to install the camera in a location that really has no illumination at night, or indoors with no light, I would still recommend getting a camera with IR illuminators. The white light LEDs on this camera are quite bright at maximum setting but still pretty bright at the lowest setting, that may not be something you want. In daytime or well-lit scenes it's outstanding. Setup was pretty easy, the web-based UI and the Android app are simple to use while still offering most (but seemingly not all) of the features you get with the desktop software.The camera has quite a few server options, both HTTP and SSL-enabled HTTPS web UIs (self-signed or you can import a key), RTMP, RTSP and ONVIF, UPnP; it also supports DDNS and NTP for time sync.Integrating the camera into my existing setup using Home Assistant and Frigate was very easy indeed, as there is a Reolink integration for Home Assistant that lets you change some settings and take actions right from Home Assistant, like turning the white light illuminators on, activating two way audio, activating the siren, changing sensitivities and so on. Adding the camera to Frigate was a cinch, the RTSP URLs are `rtsp://admin:password@ip_address:554/Preview_01_main`for the main stream and `/Preview_01_sub` for the lower quality substream. I would recommend setting up restreaming with Frigate and go2rtc to minimize the number of concurrent connections to the camera, as it is only 100MBps ethernet. This can be accomplished by adding the following to your frigate configuration yaml:```go2rtc:streams:reolink_camera_name: rtsp://admin:password@ip_address:554/Preview_01_mainreolink_camera_name_sub: rtsp://admin:password@ip_address:554/Preview_01_sub...cameras:reolink_camera_name:ffmpeg:output_args:record: preset-record-generic-audio-copyinputs:- path: rtsp://127.0.0.1:8554/reolink_camera_nameinput_args: preset-rtsp-restreamroles:- record- path: rtsp://127.0.0.1:8554/reolink_camera_name_subinput_args: preset-rtsp-restreamroles:- detect- audiodetect:enabled: truewidth: 640height: 360audio:enabled: truelisten:- bark- fire_alarm- scream- speech- yell- whatever else, see docs for list...```This will use the substream for audio detection and object detection; I'd recommend increasing the substream resolution and bitrate to the maximum 640x360 for this purpose, as there's no reason to use the main stream for object detection. Running the AI object detection models on a 4K stream will stress your GPU or even Coral AI accelerator. And using the substream works just as well in terms of detecting objects.As for the object detection built in to the camera itself, that seems to work pretty well too though I will definitely be relying on Frigate rather than the built-in stuff. Reviewing footage in the web UI is fairly easy and fast although I have to gripe that there's only a scrubber bar and apparently no list of detections and types of objects detected. There are more features like selecting only motion, people, cars, and animals, in the Reolink desktop software, but when I've tried to review footage saved on the camera's SD card, it has crashed or timed out more than half the time. After a minute or two I can reconnect to the camera and the saved footage is available to be played. I'm using a PNY 64GB SD card at the moment but I'll be swapping that out for a larger one before I mount the camera permanently. Even though I'll be saving footage to a server with Frigate, I want the onboard storage as a backup. You can, of course, format the SD card through the camera's UI.Another problem I've had is with the Timelapse function. Setting it up and activating the timelapse works, but if I try to view a created timelapse in the web UI *or* the Android app, the camera crashes and drops off the network. It does restart itself and reappears but it takes several minutes. I've been able to view timelapses using the desktop Reolink software. This is clearly not intended behavior and can probably be fixed with a firmware update.Speaking of firmware, the camera is so new that it does not appear on the Reolink support site at all, there are no downloads available for it, not a manual PDF or firmware. I think there's a stats PDF available on the main sales website but that's it. The firmware that shipped with my camera is v3.2.0.4500_2501037854. I figure a firmware update is probably in the works and will appear soon enough, I'm hoping that improves on some of the bugs.As I said I haven't yet mounted the camera where I intend, because I don't have a spare PoE injector, so I'm powering the camera off a 12V power supply. Note that this camera does *not* come with a power supply, this is one I had laying around from an older camera installation; if you don't have either a PoE switch/injector or a 12V power supply, you won't be able to use this camera right away! Also the included Ethernet cable is very short, I'm not sure it's even a meter long; I'm not really sure why it was even included. It seems like it'll be easy to mount the camera, with a base ring that you can screw in with included hardware, into which the camera will lock. I should be installing it permanently outside in the next week or so, if I have any problems I'll update the review.All in all I'm happy with the camera and I think it's a good value; especially if you have an existing Reolink setup it should be a breeze to set up; it was auto detected by the app, the desktop software, and Home Assistant, so no need to mess about with scanning the network.

Good camera. Super easy to mount and basically plug and play with a Reo NVR
