Aiming Your Camera 
PIR Motion Detector 
The Passive Infrared Motion Detector on your UltraFire™ camera is precisely 
aligned with the camera lens to give you the best chance of capturing subjects 
that come into the field of view of the camera, while not capturing pictures of 
anything that is not in the view of the camera.  
The motion detector can detect movement up to 100 feet (30.5m) away. 
However, the detection range is dependent on the temperature of the source in 
relation to the ambient air temperature.  
The UltraFire™ Motion Detector consists of two horizontal detection bands, as 
well as six different zones within each detection band. 
For the camera to take a picture two things need to happen: 
1)  An object (typically an animal) with a temperature different from the 
background temperature must be present within one of the detection bands. 
(i.e. something warmer or colder than the ambient temperature). 
2)  That object (i.e. something with a different temperature) must be moving into 
or out of at least one of the six motion detection zones. 
NOTE:  In the photo above the deer to the far right and the deer in the middle 
would each trigger the camera. The deer to the far left would not trigger 
the camera since it is above the top detection band.
