Currently, the use of Beam Photoelectric Detectors in anti-intrusion alarm systems for large areas with high security requirements such as industrial parks, factories, military areas and airports. , harbor, ... increasingly popular. The fence sensor allows for quick alerting to the security center when objects pass through infrared rays acting as virtual fences. One of the problems with using fences is the false alarms from the surrounding environment such as animals, trees, sunlight as well as artificial lighting. Understanding this issue, OPTEX, a research and manufacturing company for sensors for alarm systems, has introduced the new Smart Line fence line with a number of advantages to minimize alarms. Counterfeiting like the previous product. The product range offers a wide range of installation options to suit every requirement: 60m / 100m / 200m.

Some key features:

1. Dual Pulse Technology

The SL-QDM and SL-QDP series in the Smart Line series incorporate dual pulse technology to enhance the sending and receiving signals between the two ends to counteract ambient noise sources such as the sun, artificial light . Combined with OPTEX's three-layer sun photolithography to ensure the highest reliability in outdoor security environments.

2. 4 independent infrared rays

Using four independent infrared rays to minimize the possibility of interference from flying birds or fallen leaves, as well as conventional two-beam types.

3. IP65 outdoor protection against water and dust
The detectors are designed and manufactured to IP65 standards for efficient outdoor operation in all weather conditions. The seams between the cap and the body are covered with a rubber seal to prevent the entry of water, dust, and insects.

Three-Tier Sunlight Technology (SL-QDM / SL-QDP)
This is a technology used to improve the performance of the sensor in different lighting and environmental conditions. Technology consists of 3 parts:
(1) The cover is covered with special filter material to remove light through.
(2) Photodiode devices with IR bandpass filters only allow beam IRs to share wavelengths.
(3) Additional light modules to distinguish IR light from other light sources.

Increases the intensity of Beam Beam
The intensity of the beam can be adjusted to suit a variety of locations and environmental conditions to minimize noise from the outside environment.

Easy to install
One of the most common problems encountered when installing a fence is that the receiver and transmitter need to be mounted parallel to each other over long distances. By integrating the magnifying lens x2 on each sensor. The Smart Line series allows the installer to determine the correct installation position for each transmitter.
