I'm not sure if they have acknowledged the issue, even though it is a major issue to have

@Wayne62 I hope they roll out a fix for this, the system is actually very good but because of this issue I halted installing it for clients.

@Dmadma At night time the camera using IR - which draws more power, so at night if there is an issue with power you will know about it. Can you try power the camera using a 48v POE injector or 48v...

Can you confirm if all cameras are using the same firmware?

Is onvif enabled on the hikvision nvr?

@peterxbaker The notications are now hit and miss for me, they sometimes work and I had to give up on trying to fix it. I had to drive 6 times to clients home to change settings to get them to work...
