Wireless Digital PIR Motion Detector

  • New technology is for Digital PIR Motion Detector that has digital filter and software A/D Converter chip output digital data.
  • With smart software to analyze the triggered signal lever, speed, and timing of people moving, so that digital PIR will not allow other noise signals to trigger a false alarm.
  • With 3 kinds of model FS122 normal type, FS122P PET type, and FS122L long range.
  • With a blue LED for displaying transmitter signal and low battery condition
  • Wide-angle lens for up to 100 degrees, in 3 layers, which covers a distance up to 12m.
  • Trimmer potentiometer for PIR sensitivity adjusts the detector range from 6M to12M.
  • Dual element PIR sensor and radio filter to detect signal without radio and white light noise interference.
  • Double pulse count detector function by jumper to control CPU working.
  • Built-in a red LED for displaying the walking test and zone switch which can set-up sensor zone.
  • The detector has a low battery detector function which can report to console
  • Built-in Tamper Switch, Swivel mounting bracket
  • Built-in metal shield case can bypass high power radio noise interference


The PIR motion detector can detect people's body movements within an assigned area and activate the alarm when an intruder enters or crosses its' designated detection area.

New technology is for Digital PIR Motion Detector that has a digital filter and A/D Converter CPU chip output digital data. The CPU software can detect the digital data of body weight, moving speed, and moving distance within duration to confirm that there's a real person moved and trigged alarm. Therefore, it can bypass all not people moving alarm signals. No false alarm of FS122 digital PIR Motion Detector.

The FS122L is a kind of long-range type that can transmit more power signals up to 250M distance between the PIR sensor and security. (in free space)

The FS122P is a bypass pet detector function that can bypass the signal from under 110cm and 20kg small animal. The lens is a special design for bypass pet detector function.
