Lot of 6 previously-used SurveillanceShop branded CCTV/surveillance cameras. They were removed from service after security system was upgraded. They worked at the time of decommissioning. These cameras require 12V DC or 24V AC power source that is commonly used in security installations. I have no such power supply so I cannot demo them working thus I'm selling the cameras as is. 4x ES-6008SHDVM23712 Colour, 540TVL, varifocal, vandal-proof, dome camera 1x ES-6002SH236 Colour, Super Hi-Res, dome camera w/3.6mm lens 1x ES-6008SHDVM2922 Colour, Super Hi-Res, varifocal, vandal-proof, dome camera These were several hundred dollars each when new.
