Commercial fire and security systems, designed, installed and maintainedProtecting commercial premises across Cambridgeshire and East Anglia since 2002.
Fire alarms, CCTV, intruder alarms, access control and perimeter protection, installed and maintained under a single contract. A 24-hour service line and emergency call-out, 365 days a year.






We protect commercial premises across Cambridgeshire and East Anglia, from single offices and industrial units to pharmaceutical, healthcare and technology sites with more demanding requirements.
Every system is designed, installed and maintained by the same team, under SSAIB certification for security and Fire Industry Association membership for fire. Maintenance contracts include a full system check twice a year, with a service line and emergency call-out running 24 hours a day, 365 days a year.
Before we quote, we look at the premises and identify where the risk sits, then recommend systems for those areas. That applies whether you are upgrading existing equipment, fitting out new premises, or looking for someone to maintain a system already in place.

CCTV Systems >>
HD and IP camera systems with remote viewing, and monitored options where verified response matters.

Intruder Alarms >>
Commercial intruder detection with remote signalling and monitored response, designed around how your site is used.

Access Control >>
Door entry, card and mobile credentials and multi-site systems, so you manage access without handing out keys.

Fire Alarms >>
Design, installation, commissioning and maintenance of commercial fire detection and alarm systems.

Perimeter Protection >>
Fence-line detection, external sounders and beam systems that pick up an intrusion before it reaches the building.

ANPR Cameras >>
Number plate recognition for car parks, gated sites and yards, with whitelists and automatic barrier control.

Barriers and Bollards >>
Automatic barriers, rising bollards, gates and turnstiles to control vehicle and pedestrian access.

Maintenance >>
Planned servicing and 24-hour emergency call-out on fire and security systems, including ones we did not install.

Competitive prices on installation, servicing and maintenance, and one supplier to deal with instead of three
Installed and commissioned by our own engineers, so there is no subcontractor to chase
