Which type of sensor has a range up to approximately 660 feet?

The photo beam sensor is designed to operate over long distances, making it effective for securing large areas or perimeters. These sensors utilize a light beam that is transmitted from a sender to a receiver; when the beam is interrupted, an alarm is triggered. The range of approximately 660 feet allows for coverage of extensive outdoor spaces, which is particularly beneficial in settings like warehouses, parking lots, or large outdoor residential properties. This long-range capability distinguishes photo beam sensors from other types of sensors, which typically have shorter operational ranges and different mechanisms of detecting motion or breaches. Understanding the strengths and limitations of different sensor types is essential for effective security planning.
