AN-DV-E1 series E1 video coder & decoder, mainly used in long-distance video monitoring, have function of E1 single directional transmitting video signal.

It is ensured that any device with E1 interface, such as PBX, Mobile base station, SS7 signaling device and voice post system, can seamlessly connect to E1 video coder & decoder. Also, E1 video coder & decoder can be applied in E1 based communication system, such as: LAN, WAN. MAN and wireless network.

• Video over E1 transparent transmission;
