As we’ve looked at in past articles the move to High Definition CCTV brings with it a great number of advantages over analogue. Aside from greater versatility and better methods of storing and recording footage there is also the fact that HD delivers considerably more clarity, capturing sharper and significantly better images than its analogue predecessors; a factor which, quite naturally, enhances the equipment’s effectiveness as a security measure.

However, upgrading to this superior quality technology will inevitably come at something of a cost. As in other forms of media and electronic devices (such as TV, cinema, laptops, tablets or smartphones) getting the best HD quality on your CCTV unit can be expensive – the higher the spec, the more you are going to be paying out.

For many, of course, the need to have a fully digital and high spec system is crucial for the surveillance and security of their site. For others who may need to upgrade but are limited by budget constraints then there are alternative options available which allow for HD, or near HD quality CCTV without having to completely change every aspect of your current system.

Introducing HDCVI

A relatively new innovation in the world of CCTV is the elaborately named High Definition Composite Video Interface (or HDCVI).

Basically HDCVI provides HD standard video via use of a more traditional coaxial analogue cable.  The obvious advantage of such a system of course is that if you already have standard analogue CCTV in place, then you don’t require a full overhaul of your cabling to get a high resolution recording.

HDCVI cameras can be hooked up to the pre-installed coaxial cables, providing up to 1080 HD pictures, a significant improvement on traditional CCTV units whilst saving both time and  money on installation costs you’d incur on a complete change over to HD Digital CCTV.

Additional Features

Long Distance Transmission

Depending on the quality and durability of the cables being used, it’s entirely possible for HDVCI to transmit over long distances, in some cases upwards of 500m. Whilst the resolution quality remains higher than from standard analogue cameras there is, however, the potential for interference from the cabling and fixings over longer distances which may cause some distortion.

Real Time Footage

Fully digital HD-IP systems operate over a network, processing the images within the camera itself. This can result in short time-lags (no more than a couple of seconds for the most part). However, with HDCVI the image is processed at the DVR which allows for the footage from the camera to be viewed in ‘real-time’.

No Network Issues

Whilst there are some considerable and noteworthy benefits to IP CCTV systems, which we’ve explored before, there can be occasions where problems on the network can cause issues with the CCTV. Generally this can be overcome with a thorough maintenance programme but, of course, this adds to the cost of the system. With an HDCVI based system, you are not operating on a network and as such are not married to any network issues that may arise.

HDCVI may not have the full quality, capacity or technological advances that a fully digital HD CCTV system can provide, but it does, nevertheless, deliver a versatile and high resolution upgrade on standard analogue units at a considerably lower cost.

If you are upgrading or thinking of moving to a new CCTV system at your work or home then HDCVI can be the ideal solution, depending on budget and requirements.
