Planning and Commissioning Manual
ADPRO Passive-Infrared (PIR) PRO Series by Xtralis
In this case a PRO-100H was chosen, on the one hand for a homogenous, seamless curtain,
and on the other, because the division into zones (near, middle, far) enables precise
detection of the location of a crime.
NOTE!
In regions with the climatic conditions of thick fog or snow is to be
expected, it is very important that the distance between the detectors is
at a maximum of 45-50 m.
If a video monitoring system with image analysis is used for verification
purposes, objective lenses with fixed focal lengths are usually required.
For a high quality of evaluation, it will be seen that this distance is also
desirable.
If an attempt at intrusion is only likely from one side, choosing a type of
detector with directional detection will lead to a reduction in false
alarms.

Monitoring of a Building with Dedicated Camera Surveillance
5.4.5.1 Requirements
An absolutely seamless and very secure monitoring of the exterior front of a building. The
highest possible detection rate will be assumed.
5.4.5.2 Planning
Because of the almost totally unfenced boundary of the property, only curtain detectors with
a narrow angle of aperture can be used. Depending on the length of the building the
following detectors are recommended:
PRO-45,
PRO-45H
PRO-45D,
PRO-45DH

)
PRO-100,
PRO-100H
PRO-250H
In this case a PRO-45DH was chosen.
