Intruder Alarms

Intruder alarm systems use a variety of detection methods to identify unauthorised access. Motion detector systems are among the most common, detecting movement within a building and triggering an alarm when activity is identified outside of normal operating hours.

Glass-break sensors provide an earlier warning by detecting the sound or vibration of breaking glass, helping to deter intruders before entry is gained. Perimeter alarm systems extend protection beyond the building itself, using a combination of sensors and cameras to monitor the outer boundaries of a site.

Each system offers different levels of protection, and in many cases, a combination of these technologies is used to provide a more comprehensive security solution.

Intruder alarm systems use sensors to detect potential unauthorised activity and send signals to a central control panel, which processes the information and triggers an appropriate alert.

Different detection technologies serve different purposes. Passive infrared (PIR) sensors detect changes in infrared radiation associated with movement, while glass-break detectors identify sounds or vibrations associated with breaking glass.

Perimeter detection systems may use infrared beams, pressure-sensitive sensors or video analytics to identify potential intrusions around a property's boundaries.

Depending on the system configuration, an activation may trigger an audible alarm, send notifications to designated personnel or transmit a signal to an Alarm Receiving Centre (ARC).

Effective protection depends on appropriate system design, detector positioning, configuration and maintenance, alongside integration with other security measures where required.

Intruder alarm systems are available in wireless, hardwired and hybrid configurations, each offering different benefits.

Wireless systems can be quicker to install and offer flexibility, particularly where running cables is difficult. Hardwired systems provide stable connections and may be well suited to larger premises or more complex installations.

Hybrid systems combine wired and wireless components, offering greater flexibility when adapting or expanding an existing security system.

The most suitable solution depends on factors such as building layout, security risks, operational requirements and future expansion needs.

Working with an experienced security provider can help ensure the system is appropriately designed, installed and maintained to provide reliable, effective protection.
