Wired outdoor camera / spotlight not working and reboot not working

I have two outdoor spotlight cams. They have been out for a while because I needed to get a big ladder to reset them as the lights weren’t flashing. I pressed and held the reset button on both devices multiple times and the flashing light will not come on. I tried for up to a minute. I know I have power as it was wired by an electrician and there are red lights on the front of both devices. How to fix??!
