The H.264 compression process is widely regarded as the most efficient video process for compressing moving images, because, with suitable computer resources, it can generate the lowest band widths for a given image resolution and quality.  However, most H.264 standard compression processes ignore the fact that large amounts of bandwidth and storage capacity could also be saved by avoiding the generation, transmission or storage of images (or extra resolution) which are not going to be required by the user.  This is a pity because it means that considerable wastage and unnecessary infrastructure costs are incorporated into video security systems. To appreciate the extent of this you only have to look at how many workstation monitors out there are being sent four Full-HD resolution data streams when they can actually only display four D1 or one Full-HD feed.  Geutebruck decided to do better. Going back to basics, but remaining within the H.264 standard, it produced H264CCTV, a process much better adapted to video security systems, their routine functions and the needs of their users. So, when H264CCTV is employed in a control centre, H264CCTV-supporting cameras send the four images for the workstation monitor in D1 resolution until such time as the operator asks for full screen display. Then the selected camera switches its data stream to full-HD and the others cease transmitting to the viewer. This eliminates unwanted images and unusable resolution, and slashes bandwidth and processing loads. The unusual way H264CCTV’s video frames are linked together helps it avoid many typical H.264 problems.  It doesn’t produce artefacts if an individual data package is lost in the network.  It doesn’t over-burden the display processor and hang up the system when cameras are switched. - Instead, its fast and easy decoding ensures that switching at 25fps is well within the processor’s comfort zone. - It doesn’t make viewing and investigation difficult with jumps or jerks, but always replays video with smooth motion, even fast forward, backwards and frame by frame. And, with H264CCTV, event searches don’t just offer you the nearest frame with metadata attached, but always deliver precisely the frame you asked for. Then there’s the costly compromise many H.264 system users have to make between recording more frames per second than they really need, or viewing fewer frames per second than they’d really like, or both.  This frustrating situation arises because the chained frame formations in most H.264 implementations make it impossible to discard individual frames to create streams with different picture rates for different purposes. On the other hand, the independent control of recording and live video qualities was a basic requirement in the design of the H264CCTV structure so it ensures that users can have dual streams with exactly the quality of service they require.

Topping the bill at the Geutebruck Security booth was the TopLine range of high spec network cameras. Eight box cameras and a fixed dome camera offer various Megapixel resolutions, sensor types, standard colour and true day/night options. Designed for licence-free integration with its video security systems, these multi-standard cameras include support for the specialist security format H264CCTV which, unlike most H264 implementations, plays back fluid motion video, forwards and backwards, even frame by frame without any gaps. For easy installation, TopLine cameras can be powered either from a local supply or centrally by PoE. Sharing the limelight this year is Argus, a high speed, high precision, pan and tilt head which sports a thermal imaging camera.  With IP66/V4A weather and corrosion-proof housings, a dirt and water repellent window, a completely maintenance-free drive system as well as an optional air blast cleaner system, Argus ensures reliable, cost-effective operation even in inhospitable and inaccessible locations such as tunnels or marine and industrial environments. Other key roles at this year’s display were taken by the high end GeViScope+ video platform whose transcoding function enables dual channel streaming and dynamic live streaming for storage and network savings, and which supports all current compression standards – H.264, H264CCTV, MPEG4CCTV, M-JPEG and ONVIF compliance – as well as audio recording, for analog and IP cameras. Operated via Pilot, the flexible three-part management console with the latest computer technology and a whole new level of individual operator comfort, convenience and performance, the GeViScope+ is demonstrating Geutebruck’s highly reliable video analytics.

There are now four more high end models in Geutebruck’s TopLine range of progressive scan IP cameras.  Designed and made in Germany to ensure top quality and reliability, they all come with specific features to complement Geutebruck video security systems and boost overall system performance.  Besides the MJPEG and MPEG-4 compression formats, these dual-streaming cameras also support Geutebruck’s H264CCTV specialist security process, which unlike most H264 implementations, plays back fluid motion video, forwards and backwards, even frame by frame, without any gaps.  Two of the new models are fixed view, day/night, dome cameras with 1/3” CMOS sensors and integral 2.8 mm to 10 mm zoom lenses which offer full HD+ resolution (2.7MP / 1920 x 1440 pixels).  These also deliver video in full HD resolution at up to 30 fps.  The TopFD-2125 model comes in a standard housing, and the TopFD-2228 has an IP 66 vandal-resistant housing.   The other pair are 5-megapixel box cameras with 1/2.5” CMOS sensors - the TopBC-1123 being a colour camera and the TopBC-2123 a day/night camera.  These both provide full resolution (5MP / 2560 x 1920 pixels) video at up to 9 fps. Standard automatic camera features shared by all four newcomers include: white balance, exposure, electronic shutter, back light compensation, flicker reduction (flickerless) and AGC.  As well as electronic PTZ functions, they all support text insertion, motion detection, privacy masking and mirror functions.  Designed for seamless, licence-free integration into Geutebruck video surveillance systems, all TopLine cameras can be powered either from a local low voltage supply or centrally by PoE.
