4K video resolution from analogue HD

by Mark Rowe

Users of analogue CCTV can now enjoy 5MP HDTVI and 4K video resolution while using their existing cabling, says Hikvision on the launch of its third-generation analogue HD solution.

According to the Chinese manufacturers, Turbo HD 3.0 not only ensures up to 5MP HDTVI input and 4K video output but also supports latency-free 1080p HD video up to 800m and HD720p transmission up to 1200m over coaxial cable.

The makers say that their Turbo HD 3.0 products retain the ease of use of an analogue system while offering up to 5MP video and makes high-definition surveillance possible without replacing cabling or switching to IP cameras. Turbo HD 3.0 uses HDTVI technology, to do away with compatibility issues when mixing old technology with new products, the firm adds.

Hikvision says that its H.264+ compression improves encoding efficiency by up to 50pc compared to standard H.264, reducing bitrates while maintaining transmission quality without it’s claimed losing forensic details. The company adds that its H.264+ reduces memory demands in digital or network recorders and reduces data storage costs.

The Turbo HD 3.0 offers up to 1200 metres of HD720p transmission and up to 800m of HD1080p video via coaxial cable, distances bneyond HD-SDI or conventional analogue, the company adds.

A Power-over-Coax (PoC) feature means one coaxial cable carries both the video signal and the power supply. This brings reduced installation time. Turbo HD 3.0 supports UTC for remote set-up and configuration and enables control of the OSD menu and PTZ control via coaxial cable, for faster camera installation.

Hikvision offers a range of 1080p and 720p cameras including bullet, turret, and dome types – including PTZ – for indoor and outdoor use. The EXIR series comes with 2MP and 3MP resolution, for low light use. Most of the cameras feature digital noise reduction, low-light illumination, Smart infrared (IR), motorized varifocal lenses, IP66 rating, and vandal-proof housings. A 5MP fisheye model will be available in the summer, the firm adds.

The Turbo HD 3.0 DVR products are available in 1/1.5/2U sizes, supporting camera input with up to 5MP resolution. The makers add that the units could fit various applications from small to large scale with ONVIF-compliant IP cameras supported.
