Analogue CCTV cameras have been the mainstay of CCTV systems for many years, and whilst newer and more technologically advanced digital and IP cameras are increasingly becoming the camera of choice; analogue CCTV cameras still play a major role across many sites, both as legacy system components and as a preferred option to suit some site and client’s requirements.

 

In addition to being well proven; tried and tested technology; ‘Analogue only’ CCTV systems still have genuine advantages over their modern IP based counterparts – one of which comes from the use of traditional coaxial cables, which inherently creates a stand alone (closed circuit) security camera ‘network’. This not only removes any direct data security risks from a cyber attack, but also means that there is no impact on the available bandwidth to the rest of the building or network’s IT infrastructure (as there can be with some IP CCTV systems).

 

As well as remaining an effective deterrent and efficient part of your security system, analogue CCTV cameras can also benefit from the addition of some of the very latest video analytics capabilities – adding advanced functionality for the lowest cost; whilst advanced integration means that your analogue cameras can also be configured for remote monitoring by an external Alarm Receiving Centre (ARC).

 

If you are looking for the additional capabilities which are only available from some of the modern digital CCTV or IP CCTV cameras; but only need these in one or two areas across your site, you do not have to go to the expense of a completely new system. The Thompson Group Engineering team can create a ‘hybrid’ system‘, combining some of the benefits of your analogue CCTV cameras with additional network capabilities whilst minimising the associated cost – so although analogue cameras have been around for many years, they still have an important role to play in modern security systems.

 

Some of the key benefits of analogue CCTV systems include:

  • the ability to create a stand alone ‘closed circuit’ CCTV system – minimising any cyber security risks
  • the video image being transmitted to the DVR in an uncompressed state, meaning that it can be viewed live with no latency pre-compression
  • excellent performance in many different lighting conditions
  • usually being a more cost effective solution due to less complexity within the camera
  • compression of the video in the DVR, which results in a greater choice of hardware and software resources being available allowing opportunities to provide increased video quality and frame rates
  • as an analogue CCTV system does not sit on a computer network there are virtually no limits to the bandwidth that can be used and the system performance is not affected by any external system problems.
