Cameras crashing/losing connection

[surveillancelot]

Hi!

System is ds-7608n-e2/8p with 6 hikvsion cameras and one onvif camera. Every once in a while (about once/week) one or two Hikvision cameras lose connection. Those are always the same 2 cameras (both ds-2cd2132F-is). Rebooting system wakes them up. Bandwith is pretty tigh, since I have many cameras, I don't know if it might be the cause.

Easiest solution should be rebooting the system every few days, but I didn't find any option so that this would be done automatically. Is there? Or if I could make just the camera to reboot itself, it would be even better.

Any ideas what might cause it? I guess if the reason was bad wiring, they wouldn't work every time when I reboot. And if there is some occasional lost of connection due to wiring, shouldn't the camera reconnect immediately when the connection is back.

Those are always the same 2 cameras (both ds-2cd2132F-is)

For that type of problem, and especially if it's the same 2 cameras, I'd wonder about the wiring.
Whilst it's not a comprehensive indication, checking the interface counters in those cameras (assuming they have old enough firmware that telnet / SSH is available and can be enabled) might yield some useful info.
Any non-zero error counts (not dropped packets - small numbers of these are not a problem) would indicate that there are connection issues.
Conversely, zero error counts doesn't necessarily indicate zero problems.
Example :

alastair@PC-I5 ~ $ telnet 192.168.1.105
