•Product Brief

The SanYan's hardware  Encoder server SL521-S1/521-F2/521-S4/521-F4 and hardware Decoder server SL511-V1/511-V2/511-V4 
system products are designed for video monitoring and surveillance over IP networks with NDVR (Networking Digital Video Recorders). 
The SL521-S1/521-F2/521-S4/ 521-F4/511-V1/511-V2/511-V4 delivers high-quality  MPEG-4 based video over 10/100 Base-T networks
using cat5, wireless media.These Ethernt encoder/decoder servers are built on open standards that enables  you to simultaneously
view,store, and capture high-resolution video, voice,  and data.
                               
Built on a distributed client-server architecture, the SL521 series offer virtually unlimited  scalability, with support for thousands of 
cameras and audio feeds. The SL521  encoder servers come in 4 versions: SL521-S1 with one analog video input at 30  fps and one 
analog audio input SL521-F2 with two analog video input at 30 fps  and  two analog audio input; SL521-S4 with QUAD 4 analog video input 
at 30 fps  and one analog audio input; SL521-F4 with four analog video input at 30 fps and  four analog audio input; The SL511 decoder
servers come in 3 versions: SL511-V1  (match SL521-S1/S4)with one analog video output at 30 fps and one analog audio output;  SL511-
V2 (match SL521-F2)with two analog video outputs at 30 fps and two analog  audio outputs; SL511-V4(match SL521-F4) with 1 QUAD
analog video output at 30  fps and one analog audio output.
The SL521 series has powerful I/O capabilities. There is optional Digital I/O and  Relay Output via a Printer port for manual or automated 
remote control of  external devices, such as lights, gates and other alarm devices, etc.

The client site can use either PC/NoteBook with SL511-VS  Software Decoder or SL511-V1/511-V2/511-V4 hardware decoder Server for 
view  purpose. SL521/511 series products can lower the overall cost of ownership of  your video surveillance system by enabling you to
leverage your enterprise server platform and use the same maintenance programs for both CCTV and IT  equipment. This integration 
also facilitates system updates for long-term  protection of your investment in video surveillance technology
