Ultra targeted motion detection from the Motion Sensor 360 - Pinhole

Our Motion Sensor 360 - Pinhole is proving to be a very popular sensor for custom installation applications. The rear mounted sensor provides an extremely discreet option where large, ugly PIR sensors would be unacceptable. 


We sometimes get asked if the detection range on the Pinhole sensor can be reduced to make it have more of a targeted, pinpoint detection area. An example for this might be the sensor installed in shelving with LED lighting. The lights should be dimmed up as the homeowners hands reach in to the shelving, but they want to make sure the motion sensor doesn't detect every time someone is simply walking past the cabinetry. 

To do this, we can recess the sensor in a thicker surface than the maximum 5mm depth as stated on our datasheet. This acts to provide a barrel through which the PIR sensor will detect any movement across its detection beams.

In the two diagrams below we first see the sensor installed flush to the surface and the PIR detection beams spreading to their full dimension.

Next, see the recessed installation where the outer PIR beams are blocked by the recessed installation meaning a more targeted detection range.

The barrel will limit the detection angle of the sensor meaning a far smaller area will be detected, when installed in the correct location this means the detection range will not ‘leak’ any wider than intended and provide a highly targeted detection area as planned. 

The cone shaped detection range means that once ‘zoomed out’ the detection range at floor level will be drastically reduced on the recessed installation. The exact reduction will depend on the orientation of the sensor in the hole and distance from the sensor, so we advise testing the installation before committing. 

As you can see, the Pinhole motion sensor offers integrators some powerful automation options especially when installed in creative and inventive ways. Recessing the sensor and using a ‘barrelled’ installation can provide a more pinpoint detection area for specialist installations.

This can be particularly powerful when installed vertically at the top of, and the bottom of a staircase so the narrow beam fires across the stairs and detects as people enter the stair case. This can then be used to trigger targeted lighting on the stairs.
