I have a number of Hikvision cameras both outside and inside our western Canadian home, connected hardwired POE and accessed by Synology Surveillance Station. It historically has been a pretty reliable system over the years. In recent months I am finding that the DS-2CD2032F-I cameras which are a few years old are starting to get flaky (intermittently repeatedly lose connection for 15-30 mins and then reconnect) when the temperature drops below about -16 deg C (0 deg F). I have checked out the cabling, connectors, swapped things around to the network switch ports, etc, and have ruled all those causes out. I am very confident that the issue is in the camera, and associated with temperature. Things are well-sealed and I see no sign of moisture infiltration being an issue.
I have several newer larger sensor higher res DS-2CD2T85F-I5 and DS-2CD2087G2-L cameras also mounted outside on the same network, and they have been rock solid in the same temperature environment, which has been down to around -35 deg C (-30 deg F) at times. The now flaky DS-2CD2032F-I cameras have been in service for a number of years without previous issue, and through what I seem to recall being similar cold spells. So perhaps some components capacitors etc are aged and now marginal to specs – don’t know. When the cameras disconnect from SS, I also cannot access them via web browser either until they resume connection in 15-30 mins. As long as the temperature is warmer than -16 deg C, the cameras are solid, until the next temperature dip when the disconnects start occurring again.
I haven’t come across much commentary about temperature issues for the Hikvision cameras, so just wanted to share this experience for the possible benefit of others in cold climates. I don’t see any solution other than just replacing these cameras with the newer higher res cameras similar to others that I have on the network, and which don’t seem to have a problem (at least so far) with low temperature.
