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!

Suggested solutions:

• 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. Congure and place the camera and leave for at least an hour.

If the area you’re monitoring has a large temperature dierence 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.

Low Battery Warning

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.
