SSAIB approved · Police response capable

Intrusion detection that earns a police response.

SSAIB approved intruder alarms with police response capability. Wireless or hardwired, with intelligent motion sensors that filter false alarms — monitored 24/7 from our UK control room.

Graded to your risk

Systems designed to the security grade your insurer requires — Grade 2 for most commercial premises, Grade 3 where higher risk demands it.

False alarms filtered

Intelligent dual-technology sensors and sequential confirmation mean wind, wildlife and stray balloons don't trigger a 3am call-out.

Verified before escalation

Our control room confirms genuine activations with audio and video verification before keyholders or police are dispatched.

Police response capable

As an SSAIB approved installer, our monitored systems qualify for police URN response — most DIY systems don't.

App control included

Set, unset and check status from your phone. Full event history, user management and instant notifications.

Wireless or hardwired

Ajax approved wireless for speed and flexibility, hardwired for large estates. We specify what suits the building.

Intruder Alarms

An alarm is only as good as the response behind it

An unmonitored bell box deters nobody after the first minute. Our systems connect to a 24/7 UK alarm receiving centre, where trained operators verify activations and escalate to keyholders or police with a URN — in minutes, not hours.

  • 24/7 monitoring from a UK alarm receiving centre
  • Audio and visual verification of every activation
  • Police URN response for confirmed intrusions
  • Keyholder management and escalation procedures
  • Engineer call-out and maintenance included in contracts

Common questions

Intruder Alarms, answered.

Yes — we install to the grade your policy specifies and provide an SSAIB certificate of conformity, which insurers recognise. Many clients see premium reductions.

The signal reaches our control room in seconds. Operators verify it — by video, audio or sensor sequence — then notify your keyholders and, for confirmed intrusions on URN systems, the police.

Both, in the right place. Wireless (we're Ajax approved installers) installs fast with minimal disruption; hardwired suits large sites and new builds. We recommend based on your building, not our stock room.

Usually, yes. We survey the system, bring it up to standard if needed, and connect it to our monitoring — often cheaper than you'd expect.
