[SOLVED] Frequent Pixelated (blocky, blotchy, green or pink squares or dropped frame) Images in QVR but not Reolink

Post by RobHyde » Fri Apr 23, 2021 4:05 am

Does anyone have any comments or suggestions on how to fix this issue. When I view the camera image in the Reolink App in both live view and playback it's a clear image. When I view the image in QVR Pro (Live or Playback) I see huge blocks or pixelation (partial dropped frame?). I get one of these pretty much every other second. Viewing both in Live view over the same network and device etc. I have even gone so far as to remove QVR Pro and reformat it's dedicated drive and started over.

This happens with all three cameras I have (Reolink POE RLC-820A with the latest firmware version v3.0.0.177_21012101 streaming at 3840x2160 at 25 frames per second and 8192 Kbps). The POE router has 3 Cameras each using around 15w and can handle a max of 126w. I am using CAT-8 Cables for all three and they are at a distance of less than 100ft each. Normally I would think the problem would be related to line noise, distance, power etc except for the fact that the reolink live view (over the network) does NOT have the blocks but the QVR Pro live view does.

Left is playback over Reolink App Right is Playback with QVR Pro (I see this on Live View for both as well).

Thanks in advance for the help.

It's most likely due to how Reolink have adulterated the i-frame implementation against the accepted standard.
Their firmware is well known for it's proprietary flavour causing problems with 3rd party solutions.
TS-431+ for storage and media and a bunch of IP cams under Surveillance Station. TVS-473 as files backup and QVR Pro.

So sounds like no solution unless Reolink fixes with a firmware?

I have been going back and forth with Reolink. They had me run the cameras over RTSP (https://support.reolink.com/hc/en-us/ar ... rce=search). Since the image was clear they said the problem is not with the cameras but with QNAP QVR Pro. So I guess I am back to square one.

[SOLUTION]
Ok in my devastation regarding Reolinks answer I found another solution (from their website).

When I originally added the cameras I used QNAP QVR Pro >> Camera Settings >> Add Camera >> Add Manually >> Brand=Reolink; Model=RLC-820A; IP Address=<camera ip>; port=80; RTSP Port=554; .....
I had tried Generic Model and ONVIF as well to no avail. After some digging today I found why ONVIF didn't work. When you select ONVIF the port will default to 80. For ONVIF the reolink default is 8000 (see it's configuration). So set something like this.
Brand=ONVIF >> ONVIF ProfileS Cameras >> IP >> 8000 (this will most likely need to be changed) >> 554 >> 443 >> user >> Password
Then under Stream & Recording change Transport to UDP

The only downside to this method is I am no longer able to use H.265 it only allows me to choose H264.
Once I made the change above I no longer saw the pink or green pixilation / blocky / blotchy / squares.
