The NDVR system is designed for distributed Ethernet-based CCTV networks, typically in industrial settings. Specific applications include traffic video monitoring and unmanned location or SCADA (Supervisory Control And Data Acquisition) applications for process control and environmental monitoring systems, says the company.
The NDVR system comprises:SL521-S1/S4 Encoder
SL511-V1 Decoder Both systems can process MPEG4 video in real-time at 30fps and 704 x 480 NTSC resolution, says Taiwan-based Sanyan. Using MPEG-4 compression, the maximum required bandwidth is claimed to be 2Mbps for video, and 384Kbps for audio.

The SL521 encoder X86 system board is built around a 300MHz AMD Geode with 128MB of RAM. The SL521 offers a 10/100 Ethernet port, two serial ports, and a parallel port, as well as audio I/O and video I/O connections, says Sanyan. The S1 model supplies a single composite video input, and the quad-channel S4 version offers four video inputs for D1 resolution, says the company.

The fanless SL521 encoder runs on a 12VDC @18W power supply, and is equipped with DIN-rail mounting, as well as optional wall mounting. The encoder comes with a 40-60GB hard drive, as well as a 64MB server kernel DOM (Disk-on-Module) that stores a Linux 2.4.20 implementation.

The separately sold SL511 decoder, meanwhile, is a larger, but simpler box. It offers single RCA audio and composite video outputs, an Ethernet connection, and the 64MB DOM for the Linux install.
The SL521 encoder system, which fits into a single box, includes the following components:AMD Geode system board clocked to 300MHz, with 128MB RAM
MPEG4 coprocessor board based on VWeb's VW2010 codec chip with 16MB RAM (quad-processor board for S4 model)
MIC audio amplify input module for encoder
64MB server kernel DOM (Disk on Module) with embedded Linux 2.4.20
2.5-inch, 40-60GB removable IDE hard drive
Optional 8 Sensor/8 Alarm Digital Input/Output (DIO) module
Longeye surveillance application software (also runs on SL511 decoder)

Sanyan's Linux-based Longeye software decoder and surveillance application is said to provide the following features:UDP streaming
LAN/intranet multicast or unicast streaming protocol
CCD camera preview, recording, and motion detection
RS485 PTZ camera control
DVR storage file download/playback
IP network management features
Longeye surveillance application
Availability
The SL521-S1/S4 SL511-V1 are available now, says Taiwan-based Sanyan, but pricing was not disclosed. More information may be available here.
