Product Roadmap: What's Coming Next
How ColorX Technology Turn Night into Day
Reolink App v4.41 Released
Hello,I have a camera set (RLK16-820D8-A) with 8 cameras (RLC-820A).The setting is: 4K and 25fpsI am dissatisfied with the visibility of details. In daylight and at a distance of 16m, a license plate is hardly recognizable. Other details such as faces are also difficult or impossible to see.I looked for a compression setting, but couldn't find anything.What can I do?Greetings from Germany,Robert
@robert_5420 You can also adjust the bitrate in the Stream setting. When you view the video, do you view it in clear mode?You can right-click the mouse on the LiveView screen and then choose the clear mode.Here is the guide, https://support.reolink.com/hc/en-us/articles/900000662483-How-to-Playback-Recordings-Smoothly-in-Clear-Mode.
@reolink-fiona Hello!Thank you for your reply and questions.Resolution: 3840x2160Bit rate: 8MB/s (full)FPS: 25The license plate is only 16 meters away from the camera and is a sunny day. The license plate is not clearly legible.People and faces are also difficult to identify.The picture quality on the other cameras is also bad. I tested it over several days with many cars and people on multiple cameras and positions.What good is 4K resolution if the sensor blurs out all the details in the image? I am dissatisfied with the image quality of the cameras.I bought it two weeks ago from Amazon. (NVR+8Cams, ca. 1000 Euro).Attached are five photos. The last photo is the original resolution photo (3840x2160).
@robert_5420 : I have an 523WA and the same problem.This car is about 15 meters away and i can't read the license plate.
Do you have your example photo in full resolution (4K)?
@robert_5420 : The picture is taken with 5MP. That is the highest I believe.
I agree, something seems wrong. I wonder how Reolink’s software (app, client) handles h265 video and making a snapshot from it. I’m sure there’s potential problems on which computer/browser/phones Reolink’s software is running on and how it handles h265 video. It could be a problem on the hardware’s side where the Reolink’s software is running on. I’m not sure what the problem could be if you’re taking your image from the highest resolution video from the camera and making sure there’s no resolution loss.

I've tried multiple ways (Live View, PC, Mobile, USB over NVR, etc.). It doesn't matter, the same problem everywhere.

I asked a surveillance engineering pro.He told me that in his estimation the problem is that the image sensor is too small for 4K. The sensor cannot capture a clear image in 4K at all due to its small size.That would mean that a software update cannot solve the problem. The camera would be technical sc**p.

That better not be true since Reolink's stated spec is for 3840X2160 (8.0 Megapixels) at 25 frames/sec. I bought a RLC-820a camera that's going to be delivered this weekend.
Hello,i have the same problem with RLC-810Ai have set to 2k and to 4k (both max quality 8000kb encoding) there is absolute no change in quality. (i used the direct stream and encoded with VLC/ffmepg and also used the software with snapshot) even if i zoom out the picture, it result in absolute same details.there is may a bug in software or the sensor cmos has only 3MP and is scaled up by software.i also see that the stream run on 29 FPS ?? how could this possible in 4k?i hope we can clearify this issue, i do not want to have bought (on amazon) a fake 4k.
