I have 4 cameras, one doorbell and 2 battery spotlight cameras and one indoor stickup. Every single one has been doing this for weeks. So… I bought a WiFi extender a few days ago and it’s literally just feet away from the cameras (my house is tiny) - they’re all fixed except the one the extender is closest to. It’s maybe 10-12 feet away, except inside. The missing footage is always about 15 minutes long at random times.
