Luminosity Threshold Dial - Camtraptions PIR V3 Manual

Luminosity Threshold Dial
Turn the dial clockwise to increase the luminosity threshold.
Turn the dial anticlockwise to decrease the luminosity threshold.
The Camtraptions PIR sensor is able to vary its behaviour based on the
ambient light level. For example, the PIR can be configured to work only
during daylight, only during darkness or all of the time.
It is also possible to configure the PIR with no luminosity cut-off so that it will
work all of the time. In this situation, the Luminosity Threshold Dial is used to
set a Secondary Time Variable. Refer to the Program documentation below
for further details.
For Day and Night Programs, turn the dial to set the threshold between day
and night operation. For example, with the dial set somewhere in the middle,
and a Night Program selected, the camera will only be triggered in gloomy
and dark conditions. As the dial is turned anticlockwise the threshold is
lowered so the camera would only get triggered in darkness. If the dial were
turned fully clockwise, the camera would fire in all light conditions.
This behaviour is reversed in a Day Program; with the dial in the middle, the
camera would only fire in gloomy light and full daylight, with the dial turned
clockwise, it would only fire in bright sunlight and with the dial turned fully
anticlockwise, the camera would fire in all light conditions.
Please note that if you want the camera to fire in all conditions then it is
advisable to select a program without a luminosity cut-off to avoid the risk of
accidentally setting the luminosity threshold incorrectly and the camera not
operating for part of the day.
