Wireless CCTV systems have really benefited from other areas of technological advance. Primarily the same computer hardware and software which allows you to chat with your aunt in Sydney has been adapted to keep an eye on a property without the need for miles of cabling.
Essentially a camera is connected to the system using the wireless technology which is becoming standard to connect your laptop to the internet at home. With cutting edge lithium based batteries there isn't even the need for power cables as the camera can run for up to five years off these super-long-life batteries. This is sent to a central receiver which records the data to DVD or transmits it over the internet.
Flexible and simple as this system is, it is primarily commercial properties which would benefit from a CCTV system, it is after all often a requirement of a business insurance policy to have a security camera system installed. For the average home owner the cost of CCTV is still prohibitive and often a wasted expense.
