The TouchPoint security motion sensor uses extremely low energy microwaves to detect motion and works by using time intervals between transmissions noting and comparing the location of objects it detects .
Considering the very low energy levels used by the TouchPoint , the high frequency and short wavelength of the microwave transmission allows the sensor beam penetrate walls. Occasionally, under optimal conditions, the sensor can detect motion in or behind walls. For that reason false detections are rare, but when they occur, they are dependent on several factors.
- The materials used in the construction and design of the monitored area .
- Presence of windows and metal doors.
- Motion (vibrations) from occupants, motorized devices, audio/visual equipment sound levels, vehicular traffic, aircraft, HVAC and seismic activity.
The critical element here is the orientation and distance from the TouchPoint to the wall with the door and windows ,vents and objects in the room and the type of activity on the other side of the wall/window/ door .
The diagram that shows the detection ranges and angles for the Touchpoint security system in red. The center axis is distance in feet, the divisions are degrees relative to the Touchpoint mounting point.
Look at the diagram, and compare it with the location of the Touchpoint and the room(s) you are monitoring with these facts in mind:
- HVAC activity can cause false detection's if there is a large temperature difference between the outward air flow and the surrounding air. If practical, try shutting or reorienting the flow from vents away from the Touchpoint in the monitored space.
- Metal objects, particularly with flat surfaces, reflect microwaves. If the object moves due to vibrations from the operation of motorized devices in the home, airflow from HVAC activity or other sources it could trigger a false alarm. Try reorienting those objects if possible, so the reflective surfaces point away from the TouchPoint. (If the blinds and doors are metal, reorientation may not be possible, please refer to the final paragraph).
- Level of pedestrian or vehicular traffic outside or spaces near the monitored area. If that could be a problem there is a firmware update that may help. (see below)
- Pets. Many of our false detection issues are pets, particularly cats. Look for tables and flat surfaces that attract pets that are in the detection area.
Since November 2016 two firmware updates applied an improved security algorithm that will reduce false alarms. This should eliminate many of the false alarms experienced by Touchpoint users.
