Perimeter Alarm Systems (Early Warning)

Detect intrusion before entry. Beam sensors, outdoor PIR and perimeter detection designed for your site conditions and escalation needs.

Detect intrusion before doors and windows

Perimeter alarms provide earlier warning than internal-only detection. They’re ideal for yards, warehouses, rural properties and sites where you want deterrence and time to respond.

We design and install quote-based perimeter alarm systems across Perth and WA, as a standalone install or bundled into a complete security system (alarms + CCTV + monitoring).

Perimeter detection options

Beam sensors

Boundary detection for defined lines of travel and entry points.

Outdoor PIR sensors

Zone-based detection around buildings and assets.

Gate & entry monitoring

Contacts and detection for gates and controlled access points.

Camera-verified alarms

Integrate alarms with CCTV so events can be verified quickly.

Multi-zone layering

Reduce reliance on one sensor by layering boundary and zone detection.

Site-tuned setup

Technology and placement chosen to suit wind, animals, lighting and layout.

Where perimeter alarms work best

Commercial + industrial

  • Warehouses, workshops and industrial yards.
  • Storage yards with high-value assets.
  • Sites with multiple access points and after-hours risk.

Residential + rural

  • Large blocks and rural properties needing early warning.
  • Outbuildings, sheds and perimeter lines.
  • High-value areas where deterrence matters.

How it works

  1. Scope the perimeter risk: boundaries, access points, site activity and after-hours exposure.
  2. Design detection zones: what triggers an alert, and what should be ignored.
  3. Install + test: calibration and testing in real site conditions.
  4. Set escalation: contact pathways, monitoring options and response preferences.

Quote-based pricing factors (no fixed price list)

Perimeter systems vary widely by site. Quotes depend on:

  • Perimeter size and number of detection zones
  • Sensor type (beam, outdoor PIR, mixed solutions)
  • Site environment and nuisance-trigger risk
  • Integration requirements (CCTV, monitoring, access control)
  • Power/cabling constraints and installation complexity
  • Escalation workflow requirements

FAQs

Do perimeter alarms reduce break-ins?

They provide early detection and deterrence by identifying intrusion before entry points are reached, improving decision-making and response.

Will pets or animals cause false alarms?

They can if the system isn’t designed for the environment. We choose technology and placement to suit site conditions and reduce nuisance triggers.

Can perimeter alarms integrate with CCTV and monitoring?

Yes. Integration can support event verification and after-hours escalation depending on your setup and requirements.

Can you install perimeter alarms as a standalone service?

Yes. Perimeter detection can be installed standalone, or bundled into a complete system with alarms, CCTV and monitoring.
