P1-78 ongoing problem

Floodlight cam wired plus Hi, had this installed less than a month ago and am having to regularly turn it off and on again. I'm given the P1-78 error. This was in stalled by a professional electrictian. There is power and WiFi connect despite this error message. It won't allow me to go into live view or to remotely turn it off. I have to manually reboot this which defeats the object of it being a remote system. I know there is power getting to it and a WiFi connection as the notifications around persons and movements come through and I can watch these in good quality with sound. Please let me know if I need to return this and claim on the warranty. It is currently not working properly.
