Everything you need 24 hr relay, vcr for recording 2 monitors and one camera. My boses say sell, the tenants have gotton to use of the system being their judge and jury. We had one outside camera stolen so only have one left (see picture) everything is a little dusty but works. I do not know how everything works or the techinical side I know that I have to change the video tape every 48 hours or it will just copy over previous days footage. We stoped using it about a year ago. Your welcome to come by and take a look at the system. Everything is still hooked up just not the camera sure it could be easy enough to do. I am located downtown.
