Tunnel observation system overview (Hebrew): IR camera inside a tunnel, the compact field kit, eight system components, the operating scenario and advantages

Tunnel under the fence? Watch inside it.

The Tunnel Observation System is a compact field kit for continuous observation and control inside tunnels and underground spaces. IR cameras that see up to 300 m are placed by hand or lowered through a borehole.

01

Eyes inside the tunnel

IR cameras see up to 300 m in total darkness, placed by hand or through a borehole.

02

Runs on its own

Solar panels and an 11 kWh battery system power the kit from outside the tunnel, 24/7.

03

Watch from a safe distance

A secure cellular or radio link feeds a rugged control case for live view, PTZ control and recording.

A solar energy and control unit stays outside the tunnel. Video travels over a secure cellular or radio link to a rugged control case, where operators watch, steer the PTZ camera and record, around the clock. The kit is designed around the operational needs of the IDF.

From the first touch to the right response.

  1. Insert

    Place the IR camera in the tunnel by hand or through a borehole.

  2. Power

    The solar energy and control unit runs outside the tunnel.

  3. Transmit

    Data travels over a secure cellular or radio link.

  4. Control

    Watch, steer and record from the rugged control case.
