AV200 Ethernet over Twisted-Pair Transmitter (EoT) For Elevator Monitoring

Model: 7HT120 EOT Transmitter Device For Audio And Video

Audio & Video Transmission/High-Speed Data Communication

Designed for high-speed Ethernet signal transmission. It can transmit network signals over long distances through two-core wires. It is suitable for places where network cable transmission is inconvenient, such as elevators, ships, firefighting, mines, etc.

Allow Various transmission media

Supports any two-core cables ,including coaxial cables, twisted pairs, telephone lines, power cords (lower than DC 48V), ordinary wires, etc.

strong anti-interference, Simple To Use

It adopts OFDM carrier transmission principle,  ideal  for long-distance, high-reliability audio and video transmission and high-speed data communication.

Zero-Configuration Required, Easy-install

Replaces the network cable for transparent transmission, plug and play, does not require any settings, no impact on the original system either.

EoT Transmitter Overview


7HT120 is an Ethernet over Twisted-Pair (UTP) Extender/Transmitter, transmits HD videos and high-speed data signals, transfers IP HD network signals over all kinds of twisted-pair cables. (UTP/STP/2-Wire/Ethernet cable)

The EoT transmitter has advantages as long transmission range, AV200 fast communication rate, multimedia service support and flexible networking, widely applied to the transformation and upgrading of original analog system into such projects as network HD, web camera video long-range extension and elevator monitoring transmission, etc.

7HT120 EoT extender integrates twisted-pair interface and RJ45 connector, completely plug & play, doesn’t need IP address or any special installation requirement. It is very suitable for the alteration and extension projects in which cable cannot be newly added or cable is hard to be newly added.

In the elevator system usage scenario, 7HT120 EoT Transmitter can use the idle or lower than DC 48V two-core cable in the elevator accompanying cable to transmit audio and video data. The system can be used as soon as it is powered on as required, directly replacing the network cable to transmit data without any settings or changes to the original hardware or software system.
