I'm running ZM v1.30.0 with 3 IP cameras. (All different models)

On one of the cameras I have an issue where every 1 to 2 weeks the picture goes blue.
(The camera works if I connect to it via a browser)

To get it working again on ZM I just have to change any of the settings for the camera on ZM and then change back to the original setting and it start working.

Server: Ubuntu 14.04.5 LTS (GNU/Linux 4.2.0-42-generic i686)

Camera:
Wansview 1080P WiFi W2 (Black)
System Firmware 00.01.01.0042

ZM Settings:
Source Type: ffmpeg
Source Path: rtsp://admin:xxxxxxxr@192.168.1.154/live/ch0
Remote method: RTP/RTSP
32 bit colour
640x480
Orientation: Normal
Deinterlacing: Disabled

When it stops working if I change source server to local, save, and then change it back to ffmpeg and save, it works again for 1-2 weeks. Then same issue.

Not sure where to start looking at how to fix this? Any ideas? Could be it a problem with my settings?

Update: Actually see my Ubuntu version is quite old. Will upgrade and see if there are any improvements.

By default RTSP uses UDP. Try to force TCP.

add ?tcp to the end of your source string

Source Path: rtsp://admin:xxxxxxxr@192.168.1.154/live/ch0?tcp

UDP is connectionless and can sometimes go flaky. TCP acknowledges reciept of data and if it thinks something, a packet, is missing it will ask the sender to send it again.
