Security and Intruder Alarm Supply and Maintenance, London

Intruder Alarms

Tottenham Hotspur Stadium June 2019, view from East

We supply and maintain Security and Intruder Alarm systems across London and the Home Counties

All properties are different and need an experienced specialist to recommend and install a system that delivers the right amount of protection, utilises the latest in technology and provides that much needed peace of mind.

Depending on the site requirements, we can install wired and wire-free systems, using insurance approved, latest technology equipment. The alarm specified will depend on the level of security required, as well as the risks associated with the location of the premises to be protected. We will always recommend the products most suited to your individual security challenges. This can include CCTV integration, smart phone app control or perimeter protection.

Following installation PSS strongly believe a system is not complete without being supported by excellent customer service.  This is why we offer a 12-month warranty on all labour and extensive maintenance packages to ensure your system is performing optimally all year round.

If required, we offer monitoring packages providing 24/7 observation of your premises operated via our independent monitoring station EMCS. Clients have the ability to select the level of response from key-holder, security providers or the emergency services.
