system. The greater the expenditure, in terms of time and in other ways, the more likely it
becomes, as a rule, that the perpetrator will be discovered.

5.3.2 Saving Time

Three periods of time are important as part of an effective perimeter security system:
Time until the alarm
Time needed to overcome perimeter security
Time from the alarm to intervention, either on the protected object, or directly at the
scene of the crime
Clearly, having an alarm at an outer boundary, rather than at the protected object itself,
saves a lot of time. When a detector has as high a detection rate as possible, whilst at the
same time avoiding false alarms, it enables the alarm to be swiftly verified, and confers an
advantage in terms of time. The time between the alarm, and the alarm sounding or 'alert',
becomes short. 'Intervention time' is the time it takes for assistance to reach the protected
object from the alarm. The intervention time can vary according to place, time, or other
circumstances. High levels of traffic, an increase in the frequency of extreme weather
conditions, and so on, can lead to a significant increase in intervention time. This time must
be taken into account when planning perimeter security. Precise local information about
points of entry leads to more efficient and effective intervention.

5.3.3 Advantages of PRO PIR Detectors over other Technology

ADPRO PRO PIR detectors are a versatile solution for a variety of terrains and surfaces –
whether asphalt, plaster, gravel, grass, flower beds or even roofs. PIR detectors also offer a
very good price-performance ratio in relation to monitored areas.
Volumetric ADPRO PRO PIR detectors cover large spaces.
Long distance detectors, on the other hand, cover a narrow range, and can also detect
objects at great distances.
The most common uses for PIR detectors are in perimeter and exterior protection.
However, the detectors can also be used for interior monitoring, for instance in large
factories.
The preparations that have to be made on the property itself are small in relation to
the area to be protected, as in most cases foundations for fences already there can be
used to put up masts.
