Taking analogue to HD

CCTV Handbook 2019 CCTV, Surveillance & Remote Monitoring

High-definition (HD) analogue technology is nothing new as companies have been bringing analogue technology into the HD world for a number of years. But are customers biting when they are continually being told that IP is the right way to go and when there is such constant growth in the IP world?

Hi-Tech Security Solutions spoke to two companies that are driving the two primary HD analogue technologies (we were not able to get comment on AHD, which is the third main player in the HD analogue market).

Dahua Technology drives HDCVI (High Definition Composite Video Interface) technology, offering a fast and easy upgrade to high-definition video while still using conventional coax cabling, says Janis Le Roux, Africa marketing manager at Dahua Technology South Africa.

Designed by Dahua, Le Roux adds that HDCVI enables customers to transmit HD video over coax cables, at longer distances and at a lower cost. Some of the benefits of HDCVI include the following:

• Easy upgrade: HDCVI technology renders 720p to 4K HD video with the same installation and deployment processes as conventional analogue equipment.

• Long-distance transmission: HDCVI can transmit video over 500 metres with a low signal distortion rate using 75-3 coax cables.

• No latency: HDCVI is more reliable as it adopts P2P transmission with no latency and it requires no compression, which maintains the original quality of the video.

• Four signals over one cable: The Dahua technology can include video, audio, control and power signals in one cable.

Hikvision is also in the HD analogue game with HD-TVI technology (High Definition Transport Video Interface). Andrew Mu, Hikvision South Africa’s product marketing manager, says the company offers 2 MP and 5 MP HD analogue cameras along with DVRs, and it includes a number of value-added features to enhance the products’ performance.

Intelligence for analogue

Hikvision’s ColorVu is used for low-light performance and allows customers to use these cameras in almost every lighting condition. AcuSense, which runs on Hikvision DVRs, is able to offer intelligent analytics, differentiating between animals and humans and so on when using behavioural analytics (intrusion detection, line crossing, etc.).

Le Roux adds that Dahua’s HDCVI also provides intelligent functions, including facial recognition, perimeter protection, data structuring and SMD (Smart Motion Detection).

As noted above, HDCVI technology supports transmission distances of 500 metres using 75-3 cables, however it also supports power-over-coax at distances of up to 400 metres. From the HD-TVI perspective, users can transmit video up to 800 metres, but if you need power-over-coax the distance is restricted to 200 metres.

A future for HD analogue?

Despite the impressive technology available for those who prefer to stick with analogue surveillance, the question is whether the market will continue to support these systems as the capabilities and intelligence in the IP world continue to grow at a rapid rate.

Both Hikvision and Dahua are positive about the future. Mu says development on its technology is continuing and we could see facial recognition solutions for the TVI systems in the near future. Le Roux adds that Dahua is also continuing its development and we will see new functionality on the CVI platform soon, including AI features, two-way audio and more.
