Service and Maintenance for CCTV

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.

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.
