WallAlert Wall-Mounted Shock Intrusion Detection Sensor

WallAlert Shock Detector – Linear Electronic Vibration Detector

No Gaps in Detection – Protects any type of wall and drywall against impacts and vibrations caused by intrusion attempts.

Protects brick, concrete, sheet metal, and dry walls against impacts caused by intrusion attempts.

Detects drilling and breaking with a sledgehammer or jackhammer.


  • Fits: Brick, Concrete, Drywall, Sheetrock, Sheet metal wall panels, and corrugated metal panels.
  • Linear detection with no gaps. The whole cable is one long sensor.
  • Detects attacks caused by:
    • Heavy strokes or attacks from sledgehammers or explosives.
    • Repeated knocks from hammers, jackhammers, and chisels.
    • Drilling, mechanical cutting, water jet cutting tools, hydraulic jacks.
  • Plug and Deploy – Ready for installation of affordable kits.
  • Connects to the wall with multiple types of conduits/pipes.
  • No training or special tools are needed.
  • No calibration – The system self-calibrates.
  • Maintenance-free – 2 years warranty on the sensor cable.
  • Dry contact relay alarm outputs connect to any alarm system/DVR.

The Wall Break Detector Is Capable of Catching them In Real Time.

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 offers a higher level of protection and false alarm immunity than traditional shock sensors, which cannot often discriminate between ambient vibration and actual attacks.

The WallAlert Sensor cable is ideal for all types of walls and drywall to detect 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 structures such as storage warehouses, retail sites, and transportation and logistics building facades.


The WallAlert wall-mounted intrusion detection system is a passive electronic vibration 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 analyzing typical noise patterns made by a forced entry attempt. The system can recognize motion caused by an effort 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
  • Datacenters
  • Prisons
  • Secure storage areas
  • Perimeter walls
  • Roofs and floors
  • Bank vaults and safes
  • Special Access Program Facilities (SAPF)
  • Sensitive Compartmented Information Facility (SCIF)
  • Closed Areas (NISPOM)
  • Shielded Enclosure

Linear Electronic Vibration Detector Sensor Layout

1. Sensor cable attached to the wall in a conduit/pipe.

2. Each processor (analyzer) can monitor up to 2 zones (spools)

3. Maximum length per processor is 2000ft/600m of sensor cable, 1000ft/305m per zone

4. Each kit includes a processor in a weatherproof enclosure, sensor cable in the chosen length, and end of line termination unit

5. To cover longer walls there is an option to combine as many kits as needed

High Security 3m/10ft or Higher
