Ajax MotionProtect Plus

Motion detector with microwave sensor

Ajax MotionProtect Plus detects the first step of an intruder on the premises, but ignores pets, drafts and noise from an air conditioner. Radio frequency scanning filters complex interference created by thermal radiation combined with curtain movement, trembling blinds or a strong sun glare.

  • Works up to 2,000 meters from Ajax Hub in open space or across several floors of a business center
  • Avoids false alarms even in rooms or warehouses with active air conditioners and fireplaces
  • Detects motion up to 12 meters away
  • Detects the first step of an intruder
  • Processes signals digitally
  • Uses authentication to protect against fraud
  • Tamper-resistant body
  • Response from detectors can be checked every 12-300 seconds (adjustable)
  • Jamming detection, frequency-hopping
  • Uses an encrypted connection
  • 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 pirosensor
  • Filters complex interference with radio frequency scanning
  • Works under most conditions due to digital temperature compensation
  • Two-way communication with Ajax Hub allows for periodic testing and customization
  • Has a battery life of up to 5 years
  • No need to disassemble the body when installing using SmartBracket mounts
  • The quality of the connection and detection area can be tested remotely
  • Connects to Ajax Hub with a single click
  • Can be used with third-party security systems using the uartBridge and ocBridge Plus modules
