Welcome
Perimeter Security Ltd are an Oxford based security company with over 12 years experience in the industry. We specialise in scaffolding and construction site alarms as well as other "difficult to secure" sites such as remote or vacant buildings where mains electricity and telephone lines may not be available. We also install conventional residential and commercial systems to the latest standard PD6662.
Site Guard - external alarm system with mobile phone control
Our site guard system is an external alarm system that uses the mobile phone network to communicate with our central station. The system uses wireless movement sensors that can be deployed up to 1 km from the control panel and is set / unset via your mobile phone or land line. In the event of an alarm activation you can choose either to have our alarm receiving centre call your key holders or you can have the system send text messages direct to your key holders mobile phones. Activations can also be sent via email so that you can keep a log of any events. For large sites repeaters can be used increasing the rage to several kilometers. Further information here or view /
