Mounting your Alert Sensor
1.  Attach the mounting bracket for the Alert Sensor to a wall 
using the supplied screws. You may need to use wall plugs 
depending on the surface.
2.  Fit the tab on the mounting bracket into the groove on the 
back of the Alert Sensor. Slide the Alert Sensor down until 
it locks into place.
3.  Adjust the angle of the Alert Sensor accordingly.
Tips
 Ideally, the Alert Sensor should only see the entry/exit 
point (e.g., your front entrance), and the only moving 
objects in front of the sensor should be the cars or people 
you want to detect (i.e., no obstructions in the field of view).
 Avoid placing the Alert Sensor in an area where it will face 
direct or reflected sunlight, or where the environmental 
temperature may change suddenly (for example, near 
heat or cold producing devices such as heaters, air 
conditioners, or lamps).
 Any moving heat source can trigger the Alert Sensor. For 
example, a moving shadow on a sunny day may trigger the 
Alert Sensor, or the sun coming out from behind clouds. 
False triggers should be rare, but will occasionally occur.
 Wandering small animals (such as a cat or similar) can, 
under some circumstances, trigger the Alert Sensor. 
Therefore, we suggest that the Alert Sensor is not suited to 
areas where pets are routinely kept. 
For best coverage and to maximize detection, place the sensor 
approximately 2m/6ft off the ground, pointing on a slightly 
downwards angle.
