iSP901 New real-time hardware HD/SD encoder with web based management


iSP901 is a standalone HD/SD H.264/AAC encoding device ideal  for applications requiring fine detail and high-resolution images and operational reliability. The iSP901 encoding solution is designed for delivering the new level of high quality streaming in HD or SD resolutions. Based on the embedded design, iSP901 consistently performs audio and video encoding and streaming 24/7. iSP901 is implemented by selectable streaming H.264/AAC over RTSP (UDP, TCP) or MP2TS (UDP) transports thus providing the compatibility with most of retransmitting servers (Wowsa, Darim Vision RTSP retransmitter, etc.) and set-top boxes. The effective video compression and increased adaptability to existing networks allow transmitting video data of high resolution even with a lower bandwidth.

iSP901 captures and processes data from analog (CVBS, YCbCr) and digital (SDI, HDMI) audio and video sources, thus providing users with superior quality encoding streaming. It has СVBS video output and analog output for monitoring purposes.

iSP901 has a built-in web server, enabling viewing, access and control via local or wide-area networks as well as any internet connection. This robustness enables local viewing of HD video, while simultaneous streaming for remote viewing from a mobile phone, Apple® iPhone® and iPod® touch or slow internet connection.

Other iSP901 benefits are low cost, low power, small size, and noiseless operation. The two-way audio is available as an option.

Access to the iSP901 encoder can be offered though a simple web interface, or for multiple units management is supported through the Darim Vision VideoSpider™ VMS.  The VideoSpider management system offers connectivity to an unlimited number of cameras, video servers, storage servers, and control rooms. Connections between system components are organized over IP LANs, WANs and the Internet, allowing the system to be distributed worldwide.

PSIA standard conformance allows the unit to be compatible with leading industry VMS, like Milestone XProtect™, etc.
