Security Systems in Surrey and London Intruder alarms

Intruder Alarms

Thieves and criminals know that commercial properties often hold and store valuable machinery, equipment and products. The best way to protect your commercial property is with a robust security system and an intruder alarm is an important part of that.

At CFI Systems we offer a comprehensive range of intruder alarm systems individually designed in partnership with each client by our specialist team, following a detailed security assessment.

Intruder alarms are an excellent deterrent and will ensure that any intrusion will be detected immediately and the alarm sounded, alerting passers-by to the trespass and notifying nominated key-holders by text message. Clients taking subscription to our partnership alarm monitoring station can also be confident that the police will be promptly on their way. 



Our Solutions

Our solutions range from individual units through to fully monitored multiple site systems all of which can be accessed via the internet and integrated with access control, fire alarms, security lighting, CCTV and audio visual systems.






Entrusting CFI Systems to design and install your intruder system guarantees your system will be expertly installed and maintained with precision and skill. It will meet all current British and European Standards and NSI regulations whilst also incorporating your specific requirements.

All our intruder alarms can be set up for 24 hour monitoring, with police response.
