Detailed Site Plan
The production of a detailed site plan annotated with key information (refer to Appendix C for an
example) is the key element in completing a successful site survey. As a minimum, the following
information must be included:
1. Location and type of existing illumination, including coverage, to determine its suitability. If
necessary specify additional illumination.
2. The location for the installation of the Presidium system, to confirm cable run lengths for
cameras.
3. If remote monitoring is to be used, confirm the location and type of any existing
communications infrastructure.
4. Location of trees, and other vegetation that may affect detection performance, camera
positioning and field of view.
5. Type and height of fences or barriers to check where intrusion is likely to occur. Also
determine if any concealment of intruders may occur, and what is visible through fences.
6. Any other permanent or semi-permanent structures not already marked on the site plan,
e.g. semi-permanent location of large cable drums, which may obscure camera views.
7. Location of any nearby roads, to determine whether street lighting or car lights from any
roads nearby may present a lighting problem.
8. Location and description of nearby buildings or structures to understand whether lighting
may spill from adjacent properties, or shadows from industrial equipment may affect
performance, e.g. a shadow from a moving crane cast across the FOV of a camera may
cause nuisance alarms.
9. Location of any existing CCTV cameras or other detectors and their suitability with the
Presidium system, or incorporation as a third party detector.
10. Special requirements within protected areas, i.e. high security critical areas within the site,
or special requirements due to dangerous chemicals and/or service reliability.
11. If audio is considered for offsite response, identify the location of any noisy equipment, e.g.
generators, to ensure that any microphones to be installed will not be affected by the noise.
This also relates to onsite audio broadcast equipment, i.e. speakers and horns should be
appropriately located and specified with appropriate power.
Site Images
Collect a detailed set of site images covering all protected areas. The site images provide a
visual reminder when assessing the site plan offsite. These also provide a reference point during
installation and commissioning. Ideally the digital images should be taken under a variety of
lighting conditions, i.e. dawn, daylight, dusk and night. The most challenging lighting conditions
for CCTV systems can occur at dawn and/or dusk. It is vitally important to be aware of the
variable lighting conditions under different circumstances and in different seasons.
The detailed site survey must consider the likely occurrence of seasonal variations. Shedding or
sprouting of new leaves on nearby trees may affect lighting conditions and camera views. Ideally
there should be no trees in any camera views, however this is not always possible. Lighting and
views change as foliage grows or drops, affecting nuisance alarm rates or detection probability.

scenarios for a Presidium system.
