The new 'Eyetec' motion detector from Siemens is a dual-principle motion detector that combines infrared and optical sensor technology that not only senses the body heat of suspicious individuals, but can also see them, as the system is equipped with an infrared detector that is complemented by an optical sensor capable of recognising motion patterns up to 15 metres away.
Sophisticated algorithms are used to evaluate these patterns and determine their relative plausibility. If an alarm is triggered, the detector archives the images so that they can be used later to trace the cause of an incident.
The IRO Com Tool software allows users to set the conditions for triggering an alarm, either directly at the detector or at a PC, making it possible to prevent animals from triggering the alarm, because their size does not correspond to that of human beings.
The detector can also be set to trigger an alarm if it senses people walking in a particular direction. This means, for example, that museum staff can monitor if visitors actually leave the exhibition rooms after it is announced that the museum is closing for the day. In addition, the user can freely define specific surveillance zones. By marking certain areas on a live image of a monitored room, for example, the user can allow people to enter these zones without triggering the alarm. This would allow museum visitors to walk freely around exhibits positioned at various points in a room.
The detector also notices if anyone attempts to block or cover the sensor monitoring the room. Thanks to its anti-blocking function, the detector immediately triggers the alarm if its field of vision is blocked in any way.
