NexVision announced the first IP video security camera prototype based on Texas Instruments' (TI) DaVinci technology. The Nexdome Dragonfly leverages the dual-core TMS320DM644x architecture based on DaVinci technology to create a versatile, plug-and-play video security solution that can be tailored to meet specific customer demands. The company also integrated TI's differentiated analog companion products in the design of the Dragonfly, such as video decoders, amplifiers, power LDOs, power DC/DC switches, USB switch and more.

The Nexdome Dragonfly features a 360 degree X180 immersive lens on a high resolution 5MP CMOS 1/1.8 inch sensor, allowing the user to view a full scene or zoom in through a virtual pan/tilt/zoom display without diminishing image quality. Depending on the video image size, Dragonfly provides different video codecs ranging from MJPEG to MPEG4 Part 10 (H.264) from 6 frames per second (fps) in high definition up to 30 fps in VGA and D1. It also supports streaming and standard network protocols such as RTP/RTCP, PPP, HTTP, FTP, SMTP, Telnet, DNS and DHCP, as well as offering a large choice of wired and wireless IP links such as Ethernet, WIFI, Power line, xDSL and GPRS/EDGE.

The Dragonfly provides an open camera platform that is suited to large area surveillance applications such as public transportation, utility plants and medical centers, the company said. These large areas need to rely on cameras that enable monitoring centers to deal more easily with the increase in the number of surveillance cameras with advanced features, such as object detection and tracking, traffic surveillance and automatic license plate recognition. In addition, its compact size of 13-by-13cm makes installation fast and simple.

"The success of video surveillance has created a big challenge in terms of manageability," said M. Lange, business development manager for Nexvision. "TI's DaVinci technology-based processor is the only embedded media controller on the market that integrates onto one chip the image processing power and peripherals needed for high-end video analysis and H.264 D1 real-time compression for streaming video over xDSL lines."
