I purchased a few of these Hikvision PoE cameras and, unlike my other Hikvision PoE cameras, all of these cameras report Network Disconnected Exceptions in their logs every 1-3 minutes. My managed PoE switch reports the ports the cameras are using going off-line every 1-3 minutes and coming back online a few seconds later, even though there are no errors reported for these ports. I’ve tried different switch ports, different network cabling, mounting the cameras in different physical locations, connecting the cameras to an unmanaged switch, using the provided AC adapter and updating to the latest firmware, but the issue persists. HOWEVER, if I run a constant ping or ping the camera every minute, the issue is solved. It appears others have had this issue as well per https://ipcamtalk.com/threads/periodic-network-disconnected-exceptions-hikvision-ds-2cd2542fwd-iws-firmware-v5-4-1-build-160525.15645/ and https://ipcamtalk.com/threads/ds-2cd2112-domecam-network-disconnected-errors.12562/, but, since those are old threads, I thought I’d start a new one. What gives, and how do I resolve (without pings!)? Cheers.
