Installation
Installing alarms and CCTV on your property will serve as added protection and a deterrent to possible thieves. You can install a detection system that uses:
- sensors fitted to doors, windows or gates
- passive or active infrared to protect internal spaces and dual sensors incorporating PIR and microwave
- vibration and audio detectors
More sophisticated systems might use detection systems in the ground or on perimeter fencing and can combine CCTV with video motion-detection software.
The detection system should be reliable, fit for purpose and linked to an alarm system that will alert the site operators or the police (through an approved alarm-receiving centre).
Should a CCTV system need installing read the advice in the ‘Protecting your assets’ guidance.
Alarm systems
Alarm systems fall under two types:
- monitored alarm
- audible-only
Monitored alarm
A monitored alarm will, in addition to sounding an audible alarm (if required), send a signal to an alarm-receiving company who will notify the police or key-holders.
Systems should conform to:
- BS EN 50131;2006+1:2009 (refers to standard of system)
- BS 8243:2010 (standard of installation)
- BS EN 50518 (standards for the alarm-receiving centre)
If a police response is required, the alarm should also comply with the NPCC policy on security systems.
Audible-only alarm
An audible-only alarm will sound upon activation, serving to deter an intruder and attract attention.
Systems should conform to:
- BS 4737-3.0:1998 or
- BS EN 50131-1:1997 (which relates to wireless alarm systems)
The police will not attend an activation of an audible-only alarm, unless there are other factors that support it as a genuine alarm (such as the sound of breaking glass is reported).
Any alarm system should have at least two key-holders
They must be:
- familiar with the alarm controls
- able to grant access to the protected area
- contactable by phone
- available to attend within 20 minutes
