Introduction
This
article is part of the "Understanding
CCTV Series" and is an abstract from
STAM InSight - The Complete CCTV Program
on CD-ROM for Staff Training and Productivity
Enhancement.
There
is always some confusion during the hand
over of the CCTV system to the client
because the process is rarely formalized.
The installers feel they have handed over
the system, while the end user thinks
that all the problems in the system have
not been rectified. This confusion can
often cause bad blood and there is also
no clear-cut start date for the guarantee
period.
To
avoid this pitfall it is very important
to formalize the handover /takeover process.
A detailed hand over document should be
prepared which should facilitate the transfer
process. Both the installer and the end
user should tick off the items that have
been reviewed and make a note of all the
pending problems in the security system.
When these issues are resolved then the
formal transfer of the system can be completed.
A typical hand over process should cover
the following steps
- System
Audit
- System
manuals
- Operator
Instructions
- Staff
training
System
Audit
Before
testing the CCTV equipment it is important
for the installer and end user to go around
the site to each camera
point.
The end user should stand below each camera
and check out the view they expect to
see from each camera. After completion
they return to the control room to test
the CCTV system to ensure the manufacturer's
specifications and also the requirements
in the tender document are met. If you
are an installer, you should demonstrate
the following to the end user and if you
are an end user make sure you check the
following:
Cameras
Show/check
the camera performance in all the light
levels available. If the cameras are outdoors
ensure the performance is checked both
during day and night time.
Show/check
the lens coverage for each location. If
proper identification is required at a
scene, then make sure the lens being used
fulfils this condition
Demonstrate/check
that all pan tilt cameras give the required
coverage
For zoom lenses demonstrate/check they
have been back focused properly. This
means that the object of interest always
remains in focus during the zooming in
and out of the lens.

Demonstrate/check
that all cameras have been properly synchronized.
This means there should be no picture
jumping or rolling while switching. The
lack of synchronization can lead to lots
of problems. First of all it is irritating
for the operator to watch jumping pictures
on a continuous basis and it secondly
is possible this could also lead to poor
quality recording such as to skipping
of picture frames, picture tearing and
color disorientation.
Top
Switcher
Show/check
that the switchers and/or multiplexers
have been programmed properly. This means:
- Making
sure that proper addresses and camera
numbers are given to all cameras.
- Ensuring
that the keyboard functions are operating
well.
- Simulate
and show/check all the alarm functions
are working as per required.
Recording
System
- Demonstrate/check
the picture quality both during the
day and night time.
General
Demonstrate/check
the quality of the cable runs in the
site.
- Show/check
that there are no exposed cables at
the camera points.
- Show/check
the quality of BNC connections made
- Show/check
the equipment rack.
At
the time of hand over the above functions
should be effectively demonstrated and
checked.
Installation
Manual
Preparation of the installation manual
is a key part of the transfer process.
These manuals should be supplied during
hand over. They are important as a reference
during maintenance and/ or future expansion
of the security system. Each manual should
contain the following items.
- All
"as installed" drawings with
all details of equipment used
-
Description of the system: The general
description of the functions and locations
of each component of the CCTV system.
-
Manufacturer data: The following data
should be provided.
- Product
catalogue
- Installation
manual
- Users
manual with basic faultfinding
- Maintenance:
Full instructions regarding routine
maintenance should be provided
Operator
Instructions
The CCTV system will have new operators
on a regular basis. To make them operational
quickly it is a good idea to prepare instructions
on all day-to-day and other frequently
used operations, Operators instructions
should be given in simple and easy to
understand language. These instructions
could be engraved and installed near the
system keyboard.
Training
During the hand over process it is important
to train the operator and the people associated
with the management of the system. It
is a good idea to incorporate this into
the contract. The following areas should
be covered in the training
- Explanation
of the overall system and the different
components used.
- Operation
of the switcher
- Operation
of the recording system
After
all above steps have been completed and
the all-minor and major issues have been
rectified, it is advisable to exchange
formal letters that will indicate that
the handing over process has been completed.
This date will also indicate the start
of any warranty period that has been committed
by the installer.
