Even the smallest movement of the reflector is sensed, and intelligent analysis of the movement eliminates false triggers.

VISION sensor technology is a cut above the rest. Competing shock sensors most often use piezo or suspended magnet detectors that are often confused by jackhammers, loud trucks, motorcycles, and muffler-modified cars. The IP40-certified VISION 318-052 eliminates false triggers without sacrificing sensitivity by using a much more sophisticated IR impact detector.

The 318-052's sensitivity is user-adjustable, with adequate coverage of any vehicle from sub-compact cars to oversized vans and 4x4's.

• This shock sensor comes standard, in-the-box, with all VISION Security Systems.

• As you may expect, this shock sensor (or any other sensor) does not "guarantee" complete protection against theft or vandalism.
• For the vast majority of vehicles, even large vans or SUVs, the ideal sensitivity setting for the 318-052 shock sensor is 50% or less. If the Warning Chirps are going off more than you like, it means you simply need to reduce the sensitivity setting on the sensor.
