This is a quick check-list:
  1. Keep the sensors between 20-50 ft apart. FastSensor recommends 40 ft.
  2. A general rule of thumb is to have 3 sensors that are within line of sight of each other.
  3. Install sensor at heights between 9-16 ft above the floor.
  4. Don't install the sensors inside enclosures or walls; do not mount on large glass, metal, or moving surfaces; do not mount above the ceiling tiles.
