Physical protection systems
Magnetometric detecting device

Multigard (UPDS) is a magnetometric detecting device

Magnetometric detecting device Multigard is designed to control the area with a width of up to 3 m and a length of 2800 m and to detect offenders having iron and other ferromagnetic parts of equipment. The system built on the basis of Multigard is suitable for a wide range of facilities such as refineries, satellite stations, military bases, airports, ports, covert facilities, prisons, border, etc.

Multigard annunciator consists of three main parts:

Distinctive features

  • It can be used for installation into the water, for the defense against swimmers and boats
  • Fully passive system that cannot be detected by the analysis equipment
  • Connection to any control and indicating equipment

Operating principle

The principle of operation of magnetometric annunciator is based on registration of changes in the Earth’s magnetic field. The Earth’s magnetic field allows the Multigard system to distinguish the real violators from strays, birds, wind, heavy rain, fog, snow, ice, sand winds and other bad weather conditions, whereon usually the other protection systems react.


  • Full masking and inactivity;
  • Firm reinforced sensor cable;
  • Field mounted device meets all the requirements of underground and underwater installations;
  • Effective work under any type of soil, concrete, asphalt roads, runways, farmland, rocks, between trees and even under water;
  • Microprocessor-based signal processing;
  • Opportunity to create a pre-emptive border;
  • Independence from weather conditions (snow, rain, etc.);
  • Determination of the offender’s movement direction.
