CCTV
Site Survey
Environment
Is the environment metro, rural,
residential, urban, suburban,
marine, industrial etc...?
Are you close to the sea or any
other natural or unnatural
environment or conditions that
require special equipment?
Is there an existing
infrastructure to support cable
installations or does it have to
be created?
Cameras Amount of cameras to be
mounted now and possibly into
the future?
Where will the cameras be
mounted, for example hallways,
parking lots, perimeter?
Are any extreme light conditions
present, for example door
entrance areas or backlight from
a large window etc...?
Are both day and night recording
and viewing a requirement?
Are lights present, and if so,
do they use neon gas, halogen,
etc?
Will cameras be color or
monochrome?
What are the angles of view
required per camera?
Will camera housings need to be
temperature controlled, vandal
proof, or what type of material
will it be made from?
Will cameras be indoor or
outdoor?
Will cameras be wired or
wireless?
For wireless
cameras, consider the following:
-
Line of sight
-
Maximum distance from point
to point.
-
Cell towers, wireless
networks, OR power lines
present?
-
Are there other structures
that could obstruct a
signal?
-
How many PTZ cameras will be
present on the site?
-
Will it be wired or
wireless?
-
What is the data protocol to
be used?
-
What is the manufacturer's
protocol to be used?
-
What control device will be
used for the PTZ?
Power
source
Is electrical power available?
If so, what type of power, i.e.,
110, 220, 24VOLT or 12VDC?
Are any of the following
available or required?
Surge suppression.
Voltage regulator.
Lightning suppressor.
Cable
What is the maximum cable run
distance?
Will we use conventional RG-type
cable or perhaps CAT5 data type?
Should additional shielded cable
be used for some runs?
Base equipment
Will a DVR, NVR or hybrid
recording system be used?
How long does the user want
footage to be kept on the
recording system?
Does a need exist for archiving
of footage for future retrieval?
Will any form of matrix be used?
Is there a need for special
video transmission equipment?
Is there a need for
multiplexers?
Will users require remote logon
capability?
Will any form of text overlay be
required?
The
trick is then to match the
client requirement to the client
budget and ensure when
commissioning of the system is
complete that a transfer of
knowledge in the form of
physical training on the system
is performed. This ensures that
the hidden overhead associated
with callbacks due to not
getting the proper training is
reduced.
