Hikvision DS-6308DI High-definition Network Video/Audio Decoder
Hikvision DS-6308DI High-definition Network Video/Audio Decoder

There is an increasing need for high-definition video surveillance, coupled with limited solutions for simultaneous multi-channel high-quality megapixel video display. Hikvision's new 8-channel network decoder DS-6308DI is designed to meet this need by adopting H.264/MPEG4 video codec and TI's high performance DM648 platform that delivers 4ch 720P or 8ch 4CIF or 16ch CIF decoding at full frame rate (NTSC/PAL). SVGA, VGA, 2CIF, DCIF and QCIF decoding resolutions are supported as well. The DS-6308DI decoder can convert high-definition digital image data to analogue video signals -- video and audio from Hikvision DVRs, network cameras and encoders can then be displayed on the monitor via network transmission. The DS-6308DI decoder supports both VGA and BNC video output simultaneously. Decoding features include cyclic decoding, dynamic decoding and passive decoding. The product features alarm relay and alarm buzzer should a malfunction such as network disconnection, IP address conflict or illegal access occur. Network protocols such as TCP/IP, UDP, RTP, DHCP, DDNS and multicast are supported for multiple video transmission and efficient network usage. Up to 32 users can be created with multi-user management, including 1 administrator and 31 users. Voice talk, PTZ control and high speed Ethernet interface (1000/100/10Mbps) are among the many features provided. The DS-6308DI decoder offers an ideal solution for large-scale surveillance requirements, such as financial institutions, airports, transportation systems, prisons and more.

Hanwha Techwin America introduces ONVIF compliant encoder series
Hanwha Techwin America introduces ONVIF compliant encoder series

Samsung has added two new ONVIF compliant encoders to its fast growing iPOLiS portfolio of network friendly products. The four channel SPE-400 and sixteen channel rack-mounted SPE-1600R, which houses up to 4x SPE-400B four channel encoder blades, join the SPE-100 single channel encoder in providing a cost effective and easy to implement method of adding analogue cameras to an IP/network based video surveillance system. All three encoders enable images captured by an analogue camera to be transmitted in real-time across a network at 4-CIF resolution. A multi-streaming feature provides the option of utilising H.264, MPEG-4 or MJPEG compression to minimise bandwidth consumption by simultaneously transmitting images at various frame rates and resolutions to different locations on a network. "Our encoder series provide a very installer friendly method of converting an analogue CCTV system into a network based surveillance solution," said John Fisk, European IP Product Manager for Samsung Techwin Europe Limited. "Our design engineers have used their knowledge of IP and network technology to include features, which can bring operational and cost saving benefits to customers. For example, of particular importance to customers who want to add analogue speed domes onto a network, is that all three encoders support both the Samsung and Pelco D/P telemetry protocols." In the event of an alarm, the encoders can be programmed to trigger a dome to move to a preset position and, in the case of the SPE-100 and SPE-400, images relating to the alarm can be recorded onto an SD card and an e-mail notification sent. Samsung's NET-I Viewer software, which is supplied free of charge, provides customers with an easy to use graphical user interface. The SPE-100 has an additional feature in the form of a video loop through which allows captured images to be shared with other devices, such as a display monitor or locally based DVR, prior to being encoded for transmission over a network. The SPE-100 and SPE-400 offer bi-directional audio, allowing interactive communication between a camera's location and a control room, whilst both models also allow authorised users to gain access to live images, or images recorded onto a memory card inserted in the encoders' SD slots, via a web browser. Available from Samsung distributors, the three models in the Samsung encoder series are offered with full support services from Samsung Techwin Europe Ltd., including free system design, free technical support and a full three-year warranty.
