What you need. Fitting and setup.
You need a compatible Ajax hub with current software. No mains or Ethernet cable is required at the detector: it uses the two supplied batteries and Jeweller/Wings radio. Mount it indoors at the recommended 2.4 metres, facing across the likely path of movement rather than straight along it. Avoid heaters, direct sunlight, strong draughts and views through glass. Run the radio and detection-zone tests before final fixing. Pet immunity up to 20 kg and 50 cm depends on correct mounting, room layout and sensitivity. If you are unsure about coverage, seek advice before final fixing.
