Service and Maintenance for
CCTV
1. General:
Effective and regular maintenance
of a CCTV surveillance system is essential to ensure that the system remains
reliable at all times. It is advisable that maintenance of the CCTV system
should be carried out by the company which installed the system. However, the
maintenance company should have the means, including necessary spare parts and
documentation, to meet the recommendations given here.
Note:
This recommendation does not place an obligation upon customers who purchase their
systems to have them maintained by the installing company. Maintenance is a matter
of agreement between the customer and the installing company or a separate
maintenance company. Maintenance comes under BS EN 62676-4 Clause 17 & SC
CoP Guiding Principle 10.
The preservation of security
within the maintenance company is of paramount importance and steps should be
taken to ensure the safe keeping of all customers’ equipment and documentation relating
to a particular installation/contract.
Note:
BS EN 50132-7 states that “CCTV systems should be maintained in accordance with
the schedule supplied by the system designer or supplier”, but does not detail
any specific maintenance requirements. These guidelines give specific advice
for the maintenance of CCTV surveillance systems, and provide examples of the
type of documentation required to be used by the service company.
A maintenance company should
ensure that adequate vetting of all employees is carried out. All employees,
who visit a customer’s premises, shall carry identification cards which should include
a photograph and signature of the bearer, the company’s name, contact details
and a date of expiry (maximum of 3 years).
Each service technician employed
by the maintenance company should carry a range of tools, test equipment and
other equipment to enable them to perform their functions satisfactorily. Specialist
tools, test equipment and plant should be available for deeper investigation if
necessary.
Note: Disconnections, for whatever reason, should be recorded on a
maintenance record and authorised by the client or his representative.
The maintenance company’s
organisation should be so staffed as to ensure that the recommendations of this
Code of Practice can be met at all times. The following factors should be taken
into consideration:
- . the number of installations to be serviced
- the complexity of the installations;
- . the geographical spread of the installations
in relation to the location of the maintenance company, its branches and its
service personnel
- . the
method of calling out service personnel outside normal office hours, where
applicable.
- Service personnel should be
adequately trained and training should be updated whenever appropriate.

visit record.

supervised premises should be made by a representative of the company at
intervals of not less than once a year (as per SLA). Should the company, the
customer or his insurer, require more frequent maintenance, this should be clearly
stated in the maintenance record and in the contract documents.
