A house is the biggest purchase that most people will make in their lifetime, so keeping it safe is of paramount concern. There are two elements to consider when looking at home security, the interior and the exterior.

The interiors are made secure primarily by the installation of a house alarm. The alarm will detect intruders and make a loud noise; some will even notify a call centre of the intrusion so that the police can be called.

The exterior of houses can be protected by CCTV cameras; this is becoming a more regular occurrence. This is due to the price of CCTV installations falling, as well as home insurance prices being slashed due to the occupants taking extra security measures.
