Site-Guard Alarm
The Site-Guard Alarm is a 100% wireless security system designed for construction sites, vacant buildings, and utilities sites. It operates without mains electricity, using twin PIR sensors to eliminate false alarms. The system communicates via GSM for 24/7 monitoring, triggering high-output sirens and alerting key holders or response teams. Its battery lasts up to five years, making it ideal for remote or temporary locations.
Fence Alarms
Fence alarm systems protect perimeters using taut wire sensors, fibre optic cables, or microphonic technology. These systems detect climb-over, cut-through, or tampering attempts with minimal false alarms. They integrate with secondary systems like CCTV and offer adjustable sensitivity for different fence types. Wireless models are available for easy installation on chain-link, welded mesh, or wall structures.
CCTV Hire
Wireless CCTV systems provide video-confirmed alarms for construction sites and temporary locations. Up to 23 cameras with integral PIR sensors transmit 10-second video clips via mobile networks to monitoring stations. Systems can be purchased outright or hired from 120 per week for 4-camera setups. No mains electricity or telephone lines are required for deployment.
Church Roof Protection
Specialist systems prevent lead and copper theft from church roofs using wireless PIR sensors and GSM communication. Systems can be temporarily bypassed for maintenance and automatically reactivate. Intrusion triggers immediate alerts to key holders and rapid response teams, minimising damage and replacement costs for heritage sites.
Taut Wire Systems
Taut wire sensors detect fence breaches by monitoring tension changes in wire spans up to 200 feet. Available in high-security models with tilt-switches, these systems prevent climb-over or cut-through attempts. They integrate with alarm panels and offer adjustable sensitivity, suitable for chain-link fences or wall-mounted installations requiring minimal false alarms.
