What is an Active Perimeter Intrusion Alarm?
Unlike passive recording cameras that simply record video during a burglary, active perimeter alarms create an immediate defensive barrier. They detect boundary wall crossing, trigger piercing sirens, and dial your smartphone in real-time:
Dual Laser Boundary Trip Beams
Photo-electric infrared beams creating an invisible perimeter line along compound walls. Triggers when an intruder attempts to scale the wall.
110dB High-Decibel Siren & Strobe
Piercing outdoor siren and flashing strobe light that shocks and panics intruders, compelling immediate retreat before reaching doors or windows.
GSM Cellular Auto-Dialer Panel
Standalone cellular dialer that automatically calls up to 5 family mobile numbers within seconds of an unauthorized perimeter breach.
24-Hour Battery Backup Operation
High-capacity internal battery backup ensuring active perimeter protection even if burglars cut main electrical power lines.
Who Needs Perimeter Alarms?
Discover which property types require instantaneous perimeter breach shock deterrence:
Independent Villas with Compound Walls

Piercing dual-tone sounder with high-intensity flashing LED strobe light in a weatherproof polycarbonate enclosure.
Heavy-Duty Rolling Shutter Sensor
Cast-aluminum magnetic sensor engineered to withstand vehicular traffic and heavy shop shutter impacts.
Pet-Immune Digital PIR Motion Sensor
Passive infrared motion detector utilizing fuzzy logic signal processing to ignore pets under 25kg while detecting humans.
Heavy-Duty Conduit Wiring & Bracket
Tamper-proof conduit cabling along compound wall parapets with anti-rust mounting brackets and surge protection.
Why Cameras Alone Are Not Enough: The Power of Active Alarms
While CCTV gives you recordings of what happened, perimeter alarms actively stop intruders before they ever touch your windows or doors:
Deterrence at the Boundary Wall
Dual infrared laser beams create an invisible tripwire across compound walls. The instant an intruder scales the wall, sirens blare before they reach the building.
110dB Siren Shocks Intruders
Burglars rely on silence and darkness. A sudden 110-decibel piercing siren and strobe light panic intruders, causing them to flee immediately.
Instant Mobile Phone Auto-Dial
Even if you are asleep or hundreds of kilometers away, the built-in cellular dialer calls your phone instantly, bypassing silenced app notifications.
Zero False Alarms with Pet Immunity
Engineered with dual-optics and digital signal processing so that birds, squirrels, and cats never trigger sirens by mistake.
24-Hour Battery Backup Operation
Burglars often cut exterior power lines first. Broadnet alarm panels continue operating silently on emergency internal batteries.
CCTV Camera Cross-Integration
When a perimeter sensor trips, our integration prompts your CCTV cameras to immediately pan, zoom, and record the exact intrusion coordinates.

Perimeter Intrusion Alarms FAQ
Will cats, birds, or wind trigger false alarms on motion sensors?
No. We utilize advanced pet-immune digital PIR sensors and dual-beam laser technology. Small animals weighing under 25kg or falling leaves will not break both beams simultaneously, completely eliminating false triggers.
How does the GSM auto-dialer contact me if the power or home Wi-Fi fails?
The alarm panel has an internal rechargeable battery backup that lasts over 24 hours during blackouts. Because it uses a dedicated cellular GSM SIM card, it does not rely on home Wi-Fi or electricity to call your smartphone.
Can the alarm system integrate with our CCTV cameras?
Yes! In commercial and luxury villa installations, our alarm triggers can send an input relay to the Hikvision/CP PLUS NVR, causing PTZ cameras to instantly zoom and rotate directly toward the breached perimeter zone.
