The FS121H PIR motion Detector picks up persons body movement within an assigned area and activates the alarm when an intruder enters or crosses its' designated detection area.

By adopting low power consumption technologies battery life is extended. By using a COMS microprocessor IC and low noise sensor, the FS121H PIR transmits a very stable alarm signal without Radio & and Electro Magnetic wave noise interference.
