Detect Intruders In Real Time At Your Fence Line with Fence Sensors

The MICALERT Microphonic fence sensor 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 microphonic fence-mounted sensor system is based on sensing types of frequencies associated with intrusion attempts while filtering ones related to weather conditions.


The MICALERT Microphonic Cable Fence Disturbance Sensor offers a solution for intrusion detection by analyzing 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.

How Do the IRONCLAD Perimeter Sensors Detect Intruders and Not Wind?

The system utilizes three layers of false alarm filtration. 

1. The detection algorithm is designed to detect only sharp frequency vibrations associated with intrusion attempts while filtering the low frequencies from the weather conditions.

2. Automatic real-time alarm threshold adjustment with wind rejection.

3. 500 sensitivity levels are easily adjusted to adapt the sensor sensitivity to the fence condition.

The Micalert Palisade Steel Fence Sensor Is the ideal solution for protecting:

  • Commercial and Industrial areas.
  • Gated Communities
  • Data Centers
  • Water, Electrical and Utility substations.
  • Car, RV, Boat or Equipment storage areas.
  • Solar farms and Photovoltaic power plants.
  • Self Storage facilities.
  • Radio, Cellular, and Communication antennas.
  • Any fenced location.

Sensor Layout of the Fence 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 a sensor cable in chosen length.

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