Selection Tips

An alarm is activated when a receiver does not detect an infrared beam from a transmitter for a certain length of time. As the infrared beams are designed not to spread into a wide angle, and the two units (transmitter and receiver) can be installed with a long distance apart, the units are ideal for long-distance surveillance on a perimeter around plants, buildings and facilities, and also appropriate for surveillance in a specific narrow area. With the ability to minimize the influence of external light and electromagnetic interference, stable operation is ensured.
