These security devices are physical barriers installed on a vehicle’s glazing to deter unauthorized entry. They typically consist of metal rods or grilles affixed to the interior of the window frame, restricting access to the vehicle’s interior. An example includes a reinforced steel frame welded within the window recess of a fleet vehicle operating in a high-crime area.
The principal purpose of these installations is to enhance vehicle security and prevent theft. They offer a visual and physical deterrent to potential intruders, making it more difficult and time-consuming to gain entry. Historically, such measures have been employed in vehicles transporting valuables or operating in environments with elevated risk of vandalism or larceny. The benefit is a reduction in vehicle break-ins and associated property loss or damage.
