Infrared barriers provide the most reliable perimeter protection. Until now, it required expensive cabling installation, but the latest technological developments allow to avoid them.
Active infrared barriers are a method of protecting highly reliable perimeters. The use of 2 or even 4 beams prevents false alarms by animals, and the latest technology ensures good immunity to false alarms. For SmartLine Optex employs aspheric lenses 4 beams with high quality ensure correct optical focus of the beams, while the use of dual beam modulation provides excellent immunity to sunlight and other sources external light. In some models of the range also it is incorporated an optical return channel that allows the transmitter to meet the power received at the receiver, and increase the power if necessary, as in the case of presence of fog, thereby increasing system robustness and continuity in adverse weather conditions.
For these reasons, the barriers are suitable for connection to alarm systems, due to their high reliability compared to other peripheral systems that have higher rates of false alarms and that require visual verification of alarms. They are also suitable for combination with CCTV, and that by dividing a perimeter in different segments of barriers (up to 30, 60, 100, or 200 meters, depending on the barriers used), you can schedule automatic presets PTZ domes installation to orient them towards the area where the intrusion has occurred.
However, installation of barriers traditionally requires digging ditches to bring them to power wiring and connecting their alarm outputs and tamper, which expands installation time and increases costs. In some facilities also not viable lead wire to the location of the barriers, making it impossible to use traditional barriers.
To avoid these limitations, and bring the benefits of barriers in installations where the use of wired barriers would be too complex or expensive for the civil works necessary for this, Optex has developed a new concept of infrared barriers: it is wireless barriers. These barriers are based on the same principles as the outside wireless detectors Optex: its electronic, has adapted to significantly reduce their consumption by feeding feasible using lithium batteries.. In addition, the teams have space to accommodate the necessary wireless transmitters (which the alarm outputs are connected), which provides compatibility with any alarm panel or wireless transmission system which you want to use in the installation.
Optex has 4 models of wireless barriers:
-AX-100TFR: Infrared Barrier 2 beams and 4 channel, 30 meters range.
-AX-200TFR: Infrared Barrier 2 beams and 4 channel, 60 meters range.
-SL-350QNR: Infrared Barrier 4 beams and single-channel, 100-meters range.
– SL-350QFR: Infrared Barrier 4 beams and 4 channels, 100 meters range.
All are used in conjunction with LSH20 SAFT lithium batteries, 13Ah 3.6V, which are designed to work continuously and in a wide temperature range, ensuring continuity and reliability of detection. Depending on the type of barrier and the amount of installed batteries, the autonomy of the barrier varies between 3 and 8 years. Moreover, as active elements (they are emitting infrared light continuously), its energy consumption is not subject to variations, so that times of autonomy specified in the product sheets do not depend on the number of detections (unlike, example, what happens in the case of infrared detectors).
It is, in fact, an excellent solution for leveraging the inherent benefits of perimeter detection through barriers, without the need for wiring any, certainly revolutionizes the world of Edge Detection As in his day revolutionized the market external wireless detectors.
