USB connecters are often used by power supplies/chargers these days so that some electrical devices can be powered or charged from USB ports on PCs too so it might not have been the wrong lead.
Also USB can be used to supply a video signal and a power supply simultaneously so indeed could be used for a CCTV system for both the video signal and power.
