Specifications

Product information:
This series E1 video coder & decoder, use H.264, low code flow and high legible, real time video single transmit. The device based on long-distance video monitor design, assure any device with physics E1 interface can be seamless connected, ex: PBX, radix stage, SS7 order signal device and voice mail system.
 
This device can choose interface such as:
1 reverse data channel of RS485/422/232/Manchester
1 positive data channel of RS485/422/232/Manchester
1 reverse audio channel
1 positive audio channel
 
Characteristic:
  • E1 single transmit signal(N*64K), accord with G.703;
  • High efficiency, low time-lapse;
  • E1 interface have BNC (75Ω) and RJ45 (120Ω), needn’t setting;
  • Users can set the E1 channel speed according to any fact situation;
  • Video support PAL/NTSC;
  • Audio, data interface optional;
  • Have self-contained link, data and alarm direction;
  • Provide Console connector, support Console setting.
