  • Plug and Deploy – Ready for installation affordable kits.
  • Attached directly to wall to detect breaking or cutting of the wall.
  • No training or special tools needed, comes with installation manual.
  • No calibration – The system self-calibrates.
  • Maintenance free – 2 years warranty on the sensor cable.
  • 22 Levels of sensitivity per zone easily adjusted with dip switches.
  • Dry contact relay outputs (NO or NC), can be connected to any alarm system/DVR.


Detect Intruders In Real Time At Your Wall

The MICALERT Sensor cable is an ideal system for brick wall and drywall to detecting mechanical vibration transmitted along the wall as an intruder attempts to break through the wall.

The MICALERT Wall Intrusion Detection System is a passive electronic intrusion detector system. The system is ideal for outdoor protection and can be easily installed on residential or high security Steel Fence, Palisade and Ornamental fences. The MICALERT Wall Break Detection System is based on sensing types of frequencies associated with intrusion attempts while filtering ones related to weather conditions.


The MICALERT Wall Intrusion Detection System offers a solution for intrusion detection by the analysis of typical noise patterns made by a forced entry attempt. The system can recognize motion caused by an attempt to pass through the fence and disregard signals caused by weather conditions, preventing nuisance alarms.
The sensor is designed to be installed directly on rigid fences without any conduit.
The Micalert has a UV rated coating for outdoor installation and protection against all weather conditions.

The Micalert Wall Intrusion Detection System Is the ideal solution for protecting:

  • Warehouses
  • Data Centers
  • Storage Areas


Sensor Layout of the Wall Alarm System Is:

1. Sensor Cable is pre-cut in 500ft/152m and 1000ft/305m

2. Each Processor (Analyzer) can monitor up to 2 zones (spools)

3. Maximum length per Processor is 2000ft/600m of sensor cable,
2 zones of 1000ft/305m

4. Each kit also includes: A processor in a weatherproof enclosure
and sensor cable in chosen length.

5. To cover larger perimeters there is an option to combine
as many kits as needed.
