HDF-OPTICAL Alarm Module
SENSOR MODULE FOR CONTACTLESS PROTECTION OF PAINTINGS
 |
HDF-OPTICAL secures:
|
The ultra-compact HDF-OPTICAL sensor module can be easily installed behind paintings and pictures. It is fixed to the wall behind the object. A low-energy IR signal is emitted twice per second. The reflection is monitored. If any changes occur, an alarm is triggered. This enables detection, in case the picture is removed. The low energy, the very short pulse time and the large-area distribution of the IR rays prevent damage to the back of the painting to be monitored.
HDF-OPTICAL can be used both for pictures hanging on gallery rails and for wall-mounted pictures. The integrated 868 Mhz transmitter module achieves a high range even in solid buildings such as castles and palaces. The Human Detector Flex sensor HDF-OPTICAL can be combined with all alarm and voice output devices (such as HDF-BUZZER and HDF-SPEECH) and the alarm monitoring unit HDF-AMD.
