4K PoE Security Camera RLC-840A, Color Night Vision Spotlights

Very good camera, relatively easy to install, and it automatically adds to a reolink NVR. It would be nice if it had a similar mounting system to the 820A models. It has a nice wide field of view and good night vision range, especially indoors. The biggest consideration is making sure the dome is very clean inside and out to keep from having really bad IR glare at night.

Excellent cameras with very clear pictures.

Easy to install, set up to the NVR with no issues. The light and Motion detection work great. Field of view is perfect for our front door. The light goes on as designed at night and there’s two way communication through the Reolink app on my phone .

Great camera with a very clear picture. It was easy to connect and configure using the Reolink app. I only wish the screws that came with it to mount were 3 inches long.

Cameras are working good, easy setup on synology. Happy with purchase

My 2nd 4k reolink product. It's great. Have it vertically mounted. The spiders and geckos love it too. The viewing angle is really nice and wide. The night vision and the security dome are the only downsides. Any smudge or dirt on the dome causes extreme IR clouding. But I mean it's nothing a wipe down can't solve. I'll probably replace my other RLC 540s with this.

I installed more than 20 of these cameras for a client and they are very easy to configure. - Zoom feature is digital. Usable and useful - Works out of the box with minimal configuration and when used with a compatible NVR - Picture quality is great - I love the low light quality. "Turns night into day" and better than the IR assisted video. It's got IR as well but I prefer using the color mode . - Time tested and works outdoors without any issues in -10F temperatures of NY - Great camera for the price.

Reolink must really study their market carefully. This camera looks nice, and eventually functions "good enough," but it's not a great camera package - just, "OK." Whoever you buy your Reolink products from plan on updating the firmware before you get up on the ladder. They seem to ship the hardware first and ship the "fixes" later via software updates. And, don't drill all the holes until you get used to what your "product" can actually do. We had many surprises by how "just by a little bit" Reolink products don't do all they "should." They do look good once installed, and they work "OK," but they sure don't do anything extra in any sense. Having gotten used to them we've learned to trust nothing and to count on "figuring it out" - while being quick to return things that can't be made to work. (That return window closes fast when you hit a snag...) "OK" camera, silly mounting issues, limited adjustment options once in place, and "almost good" performance - nearly every time - after you work for it. Expect no help from any manuals with the product and almost nothing from "Support." Neither exists in sufficient quantity with Reolink. Too bad too, because if they knew their own products better and supported them better Reolink could have a much better reputation. So close, so often... So, "so-so."

Great camera, easy to set up and very clear picture.

This camera is wonderful! The picture is clear right out of the box (Even though I always update the firmware just to make sure there are no complications). I installed it about 8 feet off the ground on my smaller garage (under the soffit) where it would be exposed where someone could break it. It is rugged and feels great quality! It took me longer to fish the cable up inside the soffit and down to our outlet where I would inject POE than it did to screw into the soffit... Because of how I set up my network, it was instantly detected on the NVR and added! Total installation, less than 5 minutes! (although your mileage may vary depending on how your network is setup!)

Easy setup and works well. While software is much better than my previous cams, it sometimes thinks a bug flying by is a person or the shadow from the sun will trigger the motion detection... so I think it could use some improvement in that regard

Great camera, sets up in very little time. I was able to install without NVR or on board sd card, utilizing Frigate. Some of the functions like lights are not available through frigate currently. Great image quality, very stable, have not had to reboot it in months.

Pretty good so far on wall mount. I have a second unit horizontal mount under soffit boards. Not so go…… 1. On single story building the lens adjustment maximum travel still makes the view point too much to the ground. I had to make a slight wedge to go under the base in order to get the view I wanted. 2. When at maximum lens adjustment as above the night vision mode is terrible. The IR lights just reflect too much off the inside of the dome making the image unusable. Daytime mode is fine. Overall if you don’t need vandal proof then the CX820 is a much better camera.
