The LASER-3000 monitoring system has to be used when access to a room is otherwise impossible. The laser transmitter, with its beam being in the invisible infrared waveband, has to be directed to a window of the room to be monitored. A portion of the laser beam will be reflected by the window pane. The receiving part of the LASER-3000 picks up the reflected laser and converts it into electric signals which, after filtering, are amplified and fed into headphones and/or recording devices.

The laser transmitter and receiver are built in a special splash-proof aluminum housing, allowing the system to be operated in inclement weather conditions. The state-of-the-art semiconductor laser is extremely mechanically robust and, due to its low power consumption, a running time of approximately 50 hours can be achieved by each battery set.

  • Laser transmitter and a corresponding (shared in single housing)
