8 Channel Digital Video Multiplexer
Features
HM-C8V 8 Channel Digital Video Multiplexer is a fiber optic digital multiplexer for transmitting 8 channel high quality, uncompressed digital video, 8 channels of bi-directional data and audio, 4 E1 and one 100M Ethernet over a single fiber cable.
Applications for this product include CCTV, video surveillance, homeland security, ITS and etc.
Technology Characteristics
-> Each interface use the routine or conventional habits of customers physical interface, such as the use of diameter 3.5mm audio socket, data (RS485, RS422, RS232) and the use of common terminal block for key.
-> Perfect lightning protection design. Lightning injuries can be effectively reduced.
-> Use the internal power supply, more reliable and easier to install.
-> Single fiber transmission, core fiber optional
-> PAL / NTSC / SECAM compatible, studio-level transmission quality.
-> Asynchronous data transmission rate up to 128Kbps or more.
