So I recently moved into a new house which had CCTV already installed, all the cameras were connected to a power supply, so I bought a DVR and got them connected up they seem to be working fine. The issue is I don't know the brand or model of the cameras in order to set up the PTZ functions. It's along shot as all cameras look the same to me (never dealt with cctv before), but could anyone tell me what these are? http://i.imgur.com/TSOlI.jpg http://i.imgur.com/m63dq.jpg Thank you!
