WHY CHOOSE THIS PRODUCT?

• The ATZ HDMI4K-EM120TX is designed for AV installations that need long-distance video distribution alongside remote device control. Its combination of HDMI transmission, USB KVM, RS232 and IR extension can reduce the need to position source equipment next to every display or operator station.
• Support for IP networking and compatible fiber infrastructure offers flexibility when designing installations across control rooms, corporate buildings, monitoring facilities and large display environments. USB KVM is useful when operators need to interact with a remote computer, while serial and infrared control support compatible AV and control equipment.
• For procurement teams, the transmitter is worth considering when the deployment requires 4K video distribution and integrated control signals. Before ordering, confirm the compatible receiver, video resolution and refresh-rate requirements, fiber transceivers or optical interfaces, network switch configuration and the distance required for the actual installation.
