Unable to setup v3 cam on floodlight

Can anyone help me, I am unable to set up my v3 cam on the floodlight, it worked fine before but was not able to connect so I deleted it and tried to reset it up, but was unable to. The sound on the cam was very glitchy and it was unable to scan the qr code. Kinda stupid that this cam is hardwired, would be nice if I can just take it off and out a new cam in its place. Does anyone know a solution to this problem? I am heading out of town tomorrow so this is some bad timing.

The cam is not hardwired, it is plugged into the PIR module. You will need to remove the waterproof boot on the end of the replacement camera’s cord to plug it into the PIR module.
