CCTV Installation in Crymych

The number of sensors you need will depend on the size of your home. Most alarm systems feature 2-4 passive infrared sensors (PIRs) for motion detection, and 2-4 magnetic contact sensors on doors and windows. An alarm company will advise you of how many your property will need upon an inspecton.

Visible alarm systems can deter burglars. There are a range of options for what happens when an alarm is triggered. For example, there are bells only, alarm receiving centre, and homeowner monitored alarms. These are all effective as deterrence methods, and which you choose will depend on your specific needs.

Various studies have suggested that CCTV is an effective deterrent against home burglaries. In the event that a crime is committed on your property, well placed CCTV means you’ll have the evidence to help the police. It has been recorded consistantly that since CCTV systems have been installed, localised crime has fallen and has lead to more arrests.

Most cameras have a night mode to capture video in the dark. They use an infrared sensor to detect infrared light. These pictures are black and white, but still retain plenty of detail. Cameras are also able to see and record in adverse conditions such as fog, dust and smoke.
