Prevent the loss of assets and belongings with 24-hour alarm monitoring

Alarm monitoring helps back up your security with a service that ensures the correct procedures are followed and either the authorities or a dedicated keyholder is alerted to any activation.

When an alarm is triggered, it is important to ensure that the trigger is correctly verified. With an ARC (alarm receiving centre), your system can be used or even an intruder challenge system within the system itself. This will allow the operatives at the monitoring station to challenge the intruder and state that they are being watched.


A quick, reliable and wireless method of protecting your property

A wireless alarm system is a trusted and viable option for both new properties and older period properties.

With older properties, you’re unable to make significant changes to the property. As each component of a wireless alarm connects to each other wirelessly, you don’t have to make any alternations to the property.

Furthermore, wireless alarms can be installed in less time which means less disruption to your work schedule. If you would like to know more about this, please get in touch.
