Spotlight Cam Pro not working when wired

Hello,I purchase 2 “wired” spotlight cam and like all of you revived the one with the battery and also the wired kit. I installed the wired kit, confirmed power is going to the unit however the camera will only work on battery power and not wired. I connected a second wired unit to another hardwire to test the units and still nothing when it comes to power. It will only rub on battery power and will not use the hardwire. Kinda fed up with this as all of my other hardwired cameras work but this.
