Trigger speed determines how quickly, after detection by the main central/shooting sensor, will the
Trigger speed is always going to be faster when capturing images/photos than it is for recording
video due to it taking the camera a little longer to "wake up" and prepare for video recording than it
So if you want to make sure you don't miss anything then it's recommended to either set the camera
to take images or use the camera+video setting to take a photo first and then start recording the
Trail Camera Triggering & Placement - Best Practice & Information:
Your trail camera records when triggered, the trigger occurs when the camera senses heat change
within the image that is different to the ambient air temperature. This increased heat signature
within the image is usually (but not always) caused by something new entering the camera view
In most cases optimal camera placement is at 45-90 degrees from the area you expect the subject to
enter the image from. This way you are most likely to get the best picture/video possible of the
When a subject moves across the camera's field of view at 45-90 degrees to the lens axis the camera
will be much more sensitive to this movement than if the subject is moving directly towards or
The reason for the lack of sensitivity in the latter is because the size of the subject will only change
slowly as the cameras view of the subject expands or contracts against the background.
Whereas, if the camera is positioned at a 45 or 90 degree angle from where the subject enters the
view, the entire subject will appear as "new" heat change from the cameras' point of view.
As you can imagine trail camera placement is not an exact science as we cannot always rely on any
subject to enter the camera trigger area from where we want/expect them to! Trial and error is often
A recording will only be triggered when the subject is within the 35 degrees central "shooting"
sensor area. With the side PIRs the total sensing range is 100 degrees but the side PIRs will only
prepare the camera to record, it will not actually start recording until the subject enters the 35
If the air temperature is 20C and a human with a body temperature of 37C moves in front of the
camera then the camera will be sensitive to the change because of the 17C difference between the
two. If the air temperature is 30C then the camera will be less sensitive because the difference is
only 7C. With a small temperature difference between the air and subject temperatures it can be
advantageous to set the cameras sensitivity to HIGH although this could also lead to some false
triggers in some circumstances, such as a tree branch warming in the sun and then moving in the
Conversely, if a 37C object moves across a subzero air temperature of say -10C the camera will be
very sensitive to this because the temperature difference of 47C is much greater. In these
circumstances it may be advantageous to set the camera sensitivity to LOW.
