I wanted to hook up power supply box for my DVR camera system BNC type cable setup. I have a old alarm system Radionics D7212 system in a box in my garage. I wanted to know if is possible to turn it into a power supply for my camera system. Or am I just a idiot for even thinking such nonsense. I would appreciate any Help/Info someone might be able to share with me. Thank You for your time. Sean W
