1. Power supply of IPC is not stable, for example, IPC will consume more power at night with IR Led enabled, which may cause electricity insufficient.
2. Network bandwidth issue, the switcher performance is insufficient
3. Camera issue:
If only the specified camera or channel has this issue, we recommend you replace with a normal camera to check
If offline issue happens randomly with all channel, we suggest checking reason 1 and 2
If offline happens to all channel at same time, please check if the camera is powered by centralized supply, please check the power status
