Maintenance CCTV

Maintenance CCTV


Effective and regular maintenance of a CCTV surveillance system is essential to ensure that the system remains reliable at all times. Regular maintenance by the maintenance company and effective failure reporting by the user will enable potential problems to be identified at an early stage so that appropriate action can be taken.
Maintaining a CCTV system is preceded by proper planning, design and installation of such systems. See BSIA Form 109 for further information. Whilst maintenance of CCTV systems in the main may be voluntary, there are some legislative requirements recently introduced by Government that may impact on the ongoing maintenance or indeed need for a CCTV system.CCTV Maintenance


  1. Cleaning, using a dry cloth for cleaning is sufficient but a moist, fluff-free cloth or leather shammy may also be used. Do not use liquid cleaners or aerosol cleaners.
  2. Heat Sources, do not install the unit near any heat sources such as radiators, heaters, stoves, or other equipment (including amplifiers) that produce heat.
  3. Water, never spill liquid of any kind on the unit.
  4. Controls adjustment, adjust only those controls specified in the operating instructions. Improper adjustment of other controls may cause damage to the unit.
  5. Power sources, operate the unit only from the type of power source indicated on the label.
  6. Servicing, unless qualified, do not attempt to service this unit yourself. Refer all servicing to qualified service personnel.
  7. Attachments, changes or modifications, only use attachments/accessories specified by the manufacturer. Any change or modification of the equipment, not expressly approved by Bosch, could void the warranty or, in the case of an authorization agreement, authority to operate the equipment.
