Hi nutter. I priced one today from a number of different suppliers who will sell you the gear directly. The equipment including a good hard drive recorder, 4 colour internal cameras and a monitor will cost you about 2,800 including vat. The cabling would be fairly reasonable. depending on the cameras actually picked about € 100 per camera at the outside. If you are not into DIY shop around a lot, there are a lot of wafflers in the CCTV business and do not buy unless you are very happy with the system.
