Stability Monitor Sentry B1 Suitcase
  • Firefighter and USAR applications
    Leader SENTRY laser allows to monitor the distance of the structure to be monitored during a fire, as well as during a rescue-clearance operation.
  • Wireless connection
    The Single laser can be paired with an optional remote control allowing easy management of all settings at 100m distance. This option avoids going back and forth to the laser.
  • Accurate for optimal safety
    Leader SENTRY detects a movement of 5 mm at a distance of 30 m. A telescopic sight can point accurately the unstable structure targeted.
  • Versatility
    Multiple maximum movement thresholds (from 5 to 100 mm)
    can be selected. When a movement is sensed that exceeds the selected threshold, the sound alarm is triggered (98 dB).
    It continuously monitors detected movements and displays changes on its screen for real-time awareness.

Leader SENTRY is a stability monitor that detects the structural movements of an unstable building. Its laser continuously monitors detected movements and displays
changes on its screen for real-time awareness.

Leader SENTRY can detect a 5 mm structure movement at a distance of 30 m! A telescopic sight helps to point the laser accurately at the targeted unstable structure.

It allows firefighters and USAR teams to be alerted by a visual and audio alarm (98dB) when a structure movement, however small, is detected.

Data Sheet


PRIMARY FUNCTION Monitors movements of unstabilised and stabilised structures at distance (50m) = far safer
CONFIGURATIONS Sentry Single (1 laser head)
RISK DURING IMPLEMENTATION None as it is done in a chosen safe area and before any risk is taken, monitoring larger structurers and larger areas of work, thus protecting larger numbers of people
TECHNOLOGY Telemeter laser beam
MONITORING METHOD Monitors and detects movements from 2 mm to 100 mm.
Several thresholds (2, 5, 10, 20, 40, 70, 100 mm)
LIVE MONITORING Sentry displays distance to target(s) in real time for movement evaluation allowing to choose relevant threshold
ALARM 1 audible alarm level at 105 dB ensures alarm to be heard or OFF or Mute
ALARM OPTION Sentry proposes an out put source to plug a remote loud speaker
FLASH LIGHT 3 powerful LEDs for an about 360° visibility that give working signal or visual alarm
FILTERS Short-duration interruptions of the beam passing through it (e.g. people, birds etc.) are filtered.
ENVIRONNEMENT Designed for external positioning during fire and rescue responses
SPECIALTIES An optional wireless remote control can be paired allowing easy management from the rubble pile at a distance of 100m.
