Quad HDMI Video Receiver with two-way data voice transceiver
Table of Contents
Introduction
- This quad HDMI output Wireless COFDM Video receiver is a wireless HD receiver that supports two-way data communication(one-way video transmission and two-way data transmission).
- With two-way data transmission, two-way audio transmission, and network output video stream, it employs COFDM multi-carrier broadband demodulation and narrow-band GFSK modulation and demodulation technology.
- Its advantages include strong anti-interference and signal confidentiality.
Feature
- HDMI and network video image output are supported, as is HDMI audio output.
- Video can be previewed in four ways at the same time, or in one way only.
- Data transmission in both directions. The RS232/RS485 interface can be modified.
- Analog audio acquisition and playback functions are included.
- After powering on, the bandwidth can be automatically adjusted, and the best frequency point in the current wireless environment can be found automatically.
-
Work frequency is adjustable.
-
Adopting COFDM and GFSK modulation technology, with strong anti-interference, making it suitable for use in complex environments.
-
Built-in web interface for easy device parameter configuration
