ZAR 904.98

Wireless motion detector that notifies the owner of the first signs of home or office intrusion. The detector is fastened to the wall in front of the doors and other places likely of intruder entry.
  • Authentication to prevent forgery
  • Jamming detection and communication channels encryption
  • Tampering alarm
  • Operates up to 5 years without battery replacement
  • Ignores cats and dogs with weight of up to 20 kg and height up to 50 cm
  • Accurately detects motion in heat conditions, even at a temperature of +40°С

Maximum Performance

  • Works up to 1,700 meters from Ajax Hub in open space or across several floors of a business center
  • Detects motion up to 12 meters away
  • Processes signals digitally

Principle of operation

The device detects human presence by IR level using a passive IR sensor. The data received is digitally processed in order to prevent false alarms.

Effortless Operation
  • Adjustable to three different sensitivity levels
  • Uses our SmartMotion algorithm to avoid false alarms from animals weighing less than 20kg
  • Eliminates false alarms from gear and electromagnetic interference using a FresnelTech optical component, made from POLY IR4 material and an Excelitas PIR sensor
  • Works under most conditions due to digital temperature compensation
  • Two-way communication with Ajax Hub allows for periodic testing and customization


The device automatically increases or decreases the sensor sensitivity in order to accurately detect motion during hot and cold weather.

Bulletproof Protection
  • Authentication to prevent forgery
  • Jamming detection and communication channels encryption
  • Tampering alarm
