• Do not install cameras facing at trees or plants, which may move in the wind or drop leaves
(tree shadows may also move in the wind). In many circumstances this is unavoidable, but
should be limited as far as possible. Use the Presidium detection area selection
functionality to mask out areas with foliage.
• Do not install cameras facing into areas where there is likelihood of vehicle headlights at
night. The presence of roads near sites is unavoidable, and the positioning of cameras must
account for this. The placement of opaque material on fences near roads can alleviate most
nuisance alarms from lighting.
• Take into consideration the position of sunrise and sunset, as well as reflections from
objects in the FOV to limit any 'blinding' of the camera due to bright light.
• Do not install cameras facing into bright lights or IR illuminators.
7. Cable Selection
Typically RG59 standard (75 ohm) cable should be used as a minimum requirement:
• In a monochrome system, the cable length should be restricted to 250m (800ft) before
cable compensators are installed.
• Signal degradation due to cable length has a far greater effect on colour video, where the
coaxial cable should be restricted to 150m (500ft) before cable compensators are installed.
Other Detectors Selection and Location
The rationale behind using an additional detection technology is to provide a system that is not
susceptible to any one possible cause for nuisance or false alarms, i.e. using complementary
technologies to limit false and nuisance alarms whilst maintaining the highest detection
probability. ADPRO recommends using either long-range (for perimeter protection) or wide-angle
(for area protection) Passive Infra-Red (PIR) technology in conjunction with Presidium.
In many instances using other detection technologies with Presidium is extremely beneficial to
provide a 'double-knock' scenario. 'Double-knock' installations using a different technology can
reduce nuisance and false alarm rates to minimal levels, dramatically increasing the overall
effectiveness of the system. The benefit of verifying the nature of the intrusion through video
images is paramount, with the additional technology providing an extra level of security.
The use of PIR detectors is a well-established and field-hardened method of providing security.
The ADPRO range of PIR detectors feature long range and wide angle detectors suitable for
perimeter protection and for area protection respectively. The operable range of the detectors
varies from 18m (60ft) for the wide angle, up to 150m (500ft) for the longest range PIR. Prevailing
site conditions determine the effective range. The recommended maximum is 100m (330ft).
