Hi all, New to CCTV and wondered if anyone knows of any way to convert the electrical wiring to all my motion sensors for my alarm system to something like USB? Even if it's just power I can get from it, I was wondering if I could make use of it for a cheap Chinese IP camera with wireless IP comms but just using the wiring for the power at least? Just wondering if I can use the wiring for the sensors for anything before I rip it all down really. Thank you all!
