Questions
What are the horizontal and vertical fields of view for these Motion Sensors?
What is the detection range?
Where should I locate the sensors for the best detection?
Answer
Shown below is the range of detection for our home automation motion sensors:
|
||
| Sensor's fields of view and detection range |
| Horizontal Field of View: | +/- 45 degrees relative to the center (90 degrees total) |
| Vertical Field of View: | +/- 15 degrees relative to the center (30 degrees total) |
| Detection Range: | approximately 20 feet |
Sensor Detection vs. Motion Direction
For best results, mount the motion sensor so that someone entering the area cuts across its field of view. Try not to place a motion sensor near heating or cooling sources (heat vents, air conditioners, direct or reflected sunlight). These can trip them inadvertently.
