Project
A capital city in Africa is experiencing growth and with it, increasing vehicle traffic. To help manage the burgeoning flow of vehicles, a network of local video surveillance systems covers more than 350 intersections. This network, in conjunction with Advantech’s ARK-VH200 embedded IPC computer, simultaneously manages over 1,000 high quality real-time video streams, which will be viewed by authorities monitoring the key intersections of the city. Recording and video management are fully supported, as well as an effective data traffic management system that prioritizes data flow and prevents network overbooking. In addition to the traffic control system, urban surveillance, and the all-important public safety, the system can also provide video streaming to the Internet. Ultimately, the transportation authority of the capital city plans to build a nationwide, H.264 real time video network infrastructure.

Requirements
H.264 hardware compression and decompression
Simultaneous 4 channel preview, encoding
Anti-vibration to ensure maximum reliability
Fanless and fully sealed mechanical design
Cooled by thermal fins, heat pipes, and a heat diffuser
Easy integration, easy maintenance, and few parts
Rugged and easily mounted

System
Integrating an H.264 encoder, the ARK-VH200 captures image data from the camera, compresses the image, and sends the data to the server. The capital city’s transportation authority’s networked video and distributed recording system provides: encoding (H.264) and digital recording for video streaming; management and control of video streams and serial data across the network (30fps NTSC and 25fps PAL on each channel); integration with the Ethernet backbone for multicasting and quality of service; decoding of video streams and still pictures for viewing via the internet gateway; and system control via remote real-time monitoring for diagnostics and maintenance. Cameras are connected by BNC cables, the eSATA port connects to the HDD for plentiful image data storage space, and the LAN connects to the server -- all work together to make travel in the capital city safe and efficient, no matter what your means of transportation.

Conclusion
ARK-VH200 features an embedded H.264 H/W compression video encoder, which provides the best video frames and supports dual streaming. The lockable USB connector ensures that USB devices are well secured, even in harsh, high-vibration environments. The four BNC ports are easily connected and integrated by operators. An additional port offers PoE (Power over Ethernet), and supports an IP camera for real time IP surveillance. With SDK service that supports Windows® XP and Linux with VB, VC++, and .NET, the ARK-VH200 more than satisfies the needs of this capital city’s transportation authority.
