Be more secure at home or away, with the ever watchful eye of CCTV

Be reassured of your home security with the appropriate security systems for your needs

CCTV is a deterrent and a means of capturing evidence of criminal activity e.g. intruders outside and inside your home.

There are many different domestic camera system solutions designed for different applications e.g. varying light levels, infrared, wide angled, high and medium definition etc.

The sophistication of your camera system including security of image storage, retrieval and remote monitoring and even Police response, depends on your precise needs. 

Your NSI approved installer can explain the choices available to meet your exact requirements on your property and quote accordingly. 

You can find an approved CCTV installer via the NSI Company Finder.

NSI approved CCTV installers

NSI companies approved to design, install, commission and maintain CCTV surveillance systems must comply with NSI’s Code of Practice NCP 104. By choosing an independently approved company working to the rigorous requirements of NCP 104 you can be assured of an expert assessment of security risks and operational needs along with a detailed design proposal to ensure your exacting individual needs can be met. 

NSI approved companies will always adopt a systematic and comprehensive approach to addressing CCTV Security needs and associated Network Security threats. If the proposed system is linked to a local area network, then a security protocol should be designed into the solution to protect the CCTV system and your image data from cyber-attacks.

To enable you to manage your system and retrieve and export any images, and use Apps if any, the security company should provide you with training on the system when it is handed over and also provide all the user documentation necessary to ensure you can continue to operate and maintain the system effectively.

Care does need to be taken that the privacy of your neighbours or the general public is not invaded. Your NSI approved company will be able to advise you how to meet all of the recommended guidelines. You can also check the data protection legislation at the Information Commissioner's Office website. 

CCTV maintenance contract

Once commissioned and a maintenance contract is agreed, NSI approved companies installing CCTV systems will operate Service Level Arrangements (SLAs) and respond to a fault with your system within a specified period – typically 24 hours. 

As part of any CCTV maintenance plan your installer will be able to advise on when software and firmware updates are available and also if there are any security tasks that you should carry out to ensure the system remains reliable and secure. 

Remember that wireless devices require battery power to function and any maintenance contract needs to make clear where responsibility and cost lies for preventive maintenance, battery replacement, as well as secure storage for images.

You will also need to consider maintenance of lighting in areas covered by CCTV.
