False Triggers & How to Avoid Them
The PIR sensor is not infallible. It has been designed to use the absolute minimum
amount of power possible, which does lead to false triggers occurring in some
locations. False triggers occur whenever the PIR sensor "thinks" it detects motion
when, in fact, there is no motion to be detected (or, at least, no movement you want
to be detected).
Even the "occasional" false trigger can be extremely annoying. For example: say
you setup the OutbackCam to take three photos per motion event, and place it in a
position which, for only one hour a day, receives one false trigger per minute. At the
end of a month, this will add up to more than 5000 photos of nothing!
• Avoid placing the OutbackCam facing areas with a large and/or dynamic
temperature range. For example, an area consisting of both sunny and shady
areas will, on a clear day, create some hot areas and some cool ones. As a result,
any routine movement (such as wind in trees or a passing shadow and so on) will
trigger the PIR sensor.
• Do not aim the OutbackCam directly at an object less than 16ft/5m away. In
fact, the farther anything is from the sensor, the better. If there's nothing within
the sensor range except the people/animals you want to detect, then there's
nothing that will cause a false trigger.
• Test your setup. Configure and place the camera and leave for at least an hour.
If the area you're monitoring has a large temperature difference between day
and night, then a full day test is recommended. Multiply the number of false
triggers you get by the amount of time you plan to leave the OutbackCam in that
location to get a feel for how many false triggers you'll be dealing with over the
course of the camera's deployment.
• Don't use the OutbackCam with low batteries - under-powering the unit
will increase the frequency of false triggers, and may cause data corruption.
Remember to replace all batteries at once, and do not mix battery types.
• If all else fails, try altering the Record Delay timing. A longer Record Delay will
reduce the number of false triggers you experience, though it is unlikely to
prevent them completely.
If the AA batteries in the OutbackCam are running low, the indicator light on the front
of the OutbackCam (the one buried in the infrared LED bank) will blink three times
when the unit powered on. This is an indication that you should change the batteries
immediately.
