I've recently installed a GW Security 16 HD-CVI 12 volt camera system at my work facility in the shop. I have a couple storage buildings that will require cable lengths of 250 to 300 feet to tie the cameras to the dvr. From what I've read this will require RG-59 cable. I've also read that I shouldn't exceed 200 feet for the 12 volt power to the cameras. Could I install a remote power supply in one of the storage buildings to power those cameras? Where can I find the cable, connectors and tools to install the connectors? Feel free to correct anything that I'm off track with. Thanks!
