Not sure where in the country you are but 1 have a 4 way 80Gb DVR (recon) £50, would'nt bother with Maplins stuff but whatever camera's you want get them from a Security System supplier...ADI Global, Enterprise Security etc, you would get good varifocal, antivandal Dome cameras with 25M IR for around £50 plus vat each...I could guide you through your own installation.
