Similar issue here, but different.
Recently installed hardwired floodlight camera pro. The light is on low brightness all night. When it detects motion, it turns on high. It is set for 30 seconds, stays on high for 30 seconds, then back to low. Never off. If I force it to turn off, it’s off for maybe 3 seconds then back on low.
I’ve been through the settings multiple times, it’s not any motion settings.
