About Us

Perimeter Security Ltd is a leading provider of home alarms systems, CCTV and security systems in Oxfordshire and the Southeast. Our state of the art security systems include wireless house alarms, large network intruder alarms, security cameras and perimeter intrusion detection systems (PIDS).

We are an NSI (National Security Inspectorate) approved installer. This means all our staff and engineers have been fully vetted and cleared by the Police authority and the company is audited every twelve months to ensure we continue to work to the very latest standards and correct working practices.

We have selected a whole range of equipment taking into account its quality, reliability, style and price. Our decisions are made on years of experience within the industry therefore, once we have surveyed premises and discussed the customer’s requirements, we will select the best suited equipment for the job.

what we do


We believe that your security system should be designed for the way you live. This means taking in to account any pets and setting up the detection in to groups to make it easy for you to use. For example, you may have a “full set” a “night set” a “perimeter only set” and a “pets in set”


Our installation engineers have years of experience so you can rest asured that the installation will be neat and tidy. We often use wireless detectors so there is no need to take up floor boards etc.


We recomend an annual maintenance inspection be carried out on your security system. This makes sure that any defects are found in a timely manor and any modifications to your home or business dont affect the operation of the system. For example a piece of furniture blocking a detector.
