WallAlert Wall-Mounted Shock Intrusion Detection Sensor

The WallAlert Shock Detector protects walls and drywall against impacts caused by intrusion attempts.

The WallAlert Seismic Vibration Sensors were designed to protect high-value and high-risk assets


  • Ideal for installation on brick wall and drywall.
  • Detects attacks caused by:
    • Heavy strokes or attacks from sledgehammers or explosives.
    • Repeated knocks from hammers and chisels.
    • Drilling, mechanical cutting, water jet cutting tools, hydraulic jacks.
  • Plug and Deploy – Ready for installation affordable kits.
  • Attached with a conduit to the wall.
  • No training or special tools needed comes with an installation manual.
  • No calibration – The system self-calibrates.
  • Maintenance-free – 2 years warranty on the sensor cable.
  • Dry contact relay outputs, connects to any alarm system/DVR.

Detect Intruders In Real Time At Your Wall

The WallAlert detects vibrations caused by attempts to disturb solid structures including fixed warehouses, bank vaults, safes and perimeter walls. The WallAlert can be installed in new or existing security systems and offer a higher level of protection and false alarm immunity than traditional shock sensors, which often lack the ability to discriminate between ambient vibration and real attacks.
The WallAlert Sensor cable is an ideal system for a brick wall and drywall to detecting mechanical vibration transmitted along the wall as an intruder attempts to break through the wall.
It is designed to detect impacts on walls, by analyzing vibrations created during an intrusion attempt. The WallAlert is suitable for monitoring large building structures such as storage warehouses, retail sites and transportation and logistics building facades.


The WallAlert wall mounted intrusion detection system is a passive electronic intrusion detector system. The WallAlert Wall intrusion detection system is based on sensing types of frequencies associated with intrusion attempts while filtering ones related to non-conditions.


The WallAlert 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 WallAlert 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.

The WallAlert is Available at These Distributors.
