New D.I.S. cells: Innovation for greater reliability

Innovation in the service of reliability

(Dual interlaced scanning)

With D.I.S. technology(*) 100Hz (Double Interlaced Scanning 100Hz), each cell integrates the dual functions of transmitter and receiver. The infrared beams that are created are multiplexed and synchronized at a frequency of 100Hz.

Thanks to this technology, all columns are identical. The idea of separate transmission and reception modules has been surpassed.

The D.I.S.^(*) TECHNOLOGY 100HZ IS INNOVATION THAT SORHEA HAS DEVELOPED IN THE QUEST FOR RELIABILITY !

Dual function cells (transmission/reception)
Identical quadri-beam columns

Dual digital AGC enables compensation for variations in the incoming signal to ensure uninterrupted operation of the barrier. This digital processing of the signal is performed based on a time curve that differentiates exterior phenomena (meteorological or others) from intrusion attempts and thereby significantly reduces the number of false alarms.

The incoming signal level (blue) corresponds to the reference level (red).

1 Certain exterior phenomena (fog) can lower the strength of the incoming signal received by the receiver’s cells.

2 The AGC increases the amplification of the signal to the reference level according to the time curve.

The incoming signal level is greater than the reference level.
The AGC lowers the amplification of the signal to the reference level according to the time curve.

Détection bi-faisceaux adjacents

Detection is carried out by 2 adjacent beams, avoiding the gap of non-detection of traditional barriers.

Mono-détection temporisée sur le faisceau bas

The lower beam can be configured in time-delayed mono-detection mode in order to detect possible intrusions by climbing (advanced configuration by computer).

These particular functions provide COLIRIS II with a very high capacity for detection.

COLIRIS II has output switches for each column.

This feature permits maximum limitation of wiring constraints.

You choose, with respect to your needs and constraints, where to wire alarm switches, at one end or the other of the infrared barrier.

There are multiple possibilities for wiring and output switches !

Selectable channels allow installation of up to 4 adjacent barriers while preventing risk of interference among them.
