Intruder Detection Systems protect prisons, power stations and public services throughout the UK.

For sensitive buildings or installations that are unoccupied or located in isolated areas, an intruder detection system is often the first line of defence in asset protection. Regardless of sector, setting or scale, QSG has developed and delivered a wide range of intruder detection systems designed to make sure that line of defence holds firm.

Recognised for our technical and quality management processes under the National Security Inspectorate’s (NSI) Gold Standard, our design, installation and support teams are entrusted by some of the UK’s biggest organisations – including the National Probation Service – to develop and implement solutions that span their entire, often multi-site, estates.

The intruder detection systems we deploy, whether overt or covert, are typically networked to provide remote, centralised and cost-effective monitoring/alarm notification, using data inputs from any number of integrated systems – triggered by sound, sight, vibration, movement, light or process control parameters.
