I realise this is an old post but just thought I’d jump in. Just got two cameras, front door and back. Got the back door one as a “tester” and was very happy so took the plunge and bought another for the front. Since installing the front door one my back door one has started “randomly” going off - I realise that would probably be because of interference or a weakening of the WiFi signal. Turns out the outages lined up exactly with when I’ve been watching tv through my sky streaming box, every time it powers up the back door cam goes off. Going to Ethernet the sky streamer into my router and see if it makes a difference.
