Camera not detecting?

My front and occasionally back camera keeps showing events every 10 minutes or so even though nothing has happened but says no video available when clicking on it. My front is near my Wi-Fi box so has good signal strength. I’ve rebooted the devices but nothing. It doesn’t pick me up when I’ve walked in front of the house yet there will be multiple events before and after. I’m scared it could potentially miss something when needed. Plus it’s draining my battery.
