Perimeter Protection
Stop Threats Before They Reach Your Door.
Perimeter protection creates a security barrier around the boundary of your property — detecting intruders the moment they attempt to enter, not after they're already inside. We design and install layered outdoor security solutions for residential, commercial, and industrial sites across South-East Queensland.
About Our Perimeter Protection Systems
Effective security starts at the boundary. By the time an intruder has bypassed your locks and triggered an internal alarm, the damage is often already done. Perimeter protection shifts the detection point to the outer edge of your property — giving you maximum warning time and the best possible chance of deterring or intercepting a threat before it escalates.
Our team will assess your site, identify your most vulnerable boundary points, and design a layered detection solution that suits your property type, budget, and risk profile. We work with leading outdoor security manufacturers and carry out all installations to the highest standard — with full commissioning, testing, and documentation. At On Security, we offer an extensive selection of Gallagher monitored pulsed fences, ranging from 11 string topper fences to 51 string electric fences. Our premium solutions guarantee comprehensive coverage, regardless of your perimeter’s length. With boundary alerts, we equip you with the capability to respond immediately and prevent incidents before they occur.
Whether you need a simple beam detector on a residential driveway or a fully integrated perimeter detection network across a multi-hectare industrial site, OnSecurity has the experience and equipment to deliver. With 30+ years in the industry and a Gold Coast-based team servicing all of South-East Queensland, we back every installation with full commissioning, documentation, and ongoing support.

Everything You Need,
Nothing You Don't
Beam & Infrared Detection
Active infrared beam detectors create invisible detection lines across driveways, gates, and open boundaries — triggering alerts the instant the beam is broken.
Fence & Vibration Detection
Fence-mounted sensors detect cutting, climbing, or impact on perimeter fencing, providing early warning before an intruder clears the boundary.
Outdoor Motion Detectors
Weatherproof PIR and microwave motion detectors designed for outdoor environments — with pet immunity and anti-masking features to reduce false alarms.
Perimeter CCTV
Strategically positioned outdoor cameras with wide-angle coverage, night vision, and AI-based motion analytics to monitor your entire boundary 24/7.
Lighting Integration
Automatic security lighting triggered by perimeter detection — illuminating intruders and acting as a powerful deterrent before any alarm is raised.
Alarm & Monitoring Integration
Perimeter detection zones feed directly into your alarm panel and monitoring centre, enabling graded responses from alerts through to emergency dispatch.

Common Questions
Q.What is the difference between perimeter protection and a standard alarm system?
A standard alarm system detects intruders once they are already inside your building. Perimeter protection detects them at the boundary of your property — giving you earlier warning, more response time, and a stronger deterrent effect.
Q.Will outdoor detectors cause a lot of false alarms?
Modern outdoor detectors use dual-technology sensing (PIR + microwave), pet immunity, and anti-masking features to significantly reduce false alarms. Proper placement and calibration by our technicians further minimises nuisance triggers.
Q.Can perimeter protection work with my existing alarm system?
In most cases, yes. Perimeter detection zones can be added to most existing alarm panels as additional zones, or integrated via a separate controller that feeds into your current system.
Q.Is perimeter protection suitable for residential properties?
Absolutely. While commonly used on commercial and industrial sites, perimeter protection is increasingly popular for larger residential properties, acreage, and homes where early detection is a priority.
