X-Stream encoders

Aimed at the professional CCTV and surveillance market, X-Stream encoders compress analogue video signals to the highly efficient H.264 Main Profile standard to provide highest quality, low latency IP video for transmission over Ethernet. By choosing the H.264 Main Profile standard for encoding, image and video quality is noticeably better when transmitted via X-Stream video encoders (also referred to as video servers), on benchmark comparisons against competitor products utilising H.264 Baseline encoding. When testing against MPEG4 video, COE’s X-Stream range performed at a vastly superior quality, rendering faces, number plates and other key quality indicators with much more clarity than MPEG4 counterparts. In fact, a video demonstrating the difference in quality between MPEG4 and H.264 can be viewed at COE’s website: www.coe.co.uk

Advanced features
X-Stream includes advanced features such as onboard video analytics, electronic image stabilisation and dual streaming. These features enhance functionality of X-Stream encoders beyond their core function of compressing and converting analogue video to transmit over a digital network. Rather, they introduce real business value by enhancing the operational functionality of the video surveillance network, and improving efficiency of CCTV operators.

The X-Stream range includes a single channel boxed encoder, and two and four channel encoders, which may be box housed or rack mounted. The X-Stream range also includes a dual channel decoder, the X-Stream 200D, capable of decoding H.264 streaming Ethernet video for use with analogue devices. By rack mounting X-Stream encoders in a standard X-Net® rack, as many as 56 channels of analogue video may be encoded and transmitted across an IP Ethernet network from each rack chassis.

X-Stream video encoders have already been provided for an 8,000+ camera COE project at Seoul’s metropolitan subway network. The video encoders are used by Seoul Metro not only for video transmission, but for intelligent video analytics enhancement, utilising the embedded analytical capabilities of the product.

The onboard analytics engine of X-Stream encoders is powered by COE’s intelligent video analytics package. Analytics uses complex algorithms to identify and alert surveillance operators to a wide variety of rules. These rules include detection of abandoned objects, unauthorised access, vehicle tracking and more. The addition of COE’s I-Command® SmartDetect intelligent analytical processing to the feature set of X-Stream video encoders, enhances the function of analogue cameras and improving effectiveness of CCTV operators.

COE’s I-Command SmartDetect has already been deployed at the Port of Singapore, for logistical and security enhancement purposes. At the port, vehicle movements around the port are tracked by SmartDetect, with alarms raised when the movement of freight is held up for too long at any particular area across the 10km2 site.

The X-Stream range also features the ‘World’s first direct-to-fibre video encoder’. This product, the X-Stream 400 FX-VL offers the additional functionality of encoding and compressing video for fibre optic transmission across extended distances. With COE’s fibre modules, transmission of distances of up to 180km is possible, suiting the medium for transmission from remotely based sites.

The fibre port on X-Stream 400 FX-VL is also Coarse Wave Division Multiplexing (CWDM) enabled. By utilising COE’s X-Net CWDM card in association with multiple X-Stream 400 FX-VL units, up to 36 channels of H.264 encoded IP video can be transmitted across a single optical fibre simultaneously.

Exciting development
Ian Jefferson, CEO of COE Ltd comments: “The X-Stream range is an exciting development in the video transmission market. Enabling analogue cameras to stream low-latency, low-bandwidth video across an Ethernet network is of huge benefit to sites looking to provide an incremental upgrade path from analogue to IP. The addition of video analytics and other key features such as ‘Direct-to-fibre’ IP encoding offers the user a sophisticated and flexible package for the modern surveillance system.

“Providing highest quality video has been the focus of COE Limited for over 20 years, and X-Stream has been designed and manufactured with this same focus. This range of encoders and decoders are game changers in the field of video surveillance, combining superior video quality with lowest latency to deliver astonishing results.”
