Lack of motion detection

[Jcapache41]

I live on a busy street. Where in the past I had to silence my motion alerts every 24 hours. However lately with the ultra that is not the case I hardly get motion alerts now.. I have a couple of other ultras in other spots and the same thing. I have motion detection sensitivity on 100. I have power management on best video. But two of my ultras the last time I got a motion video in my feed was 9pm last night my other ultra 8pm Friday night. This is impossible because I live in a busy street. What can’t these cameras just work properly.

Have you rebooted the hub and maybe reinserted the camera batteries to get back to a known state?
