Introduction of long range cofdm army wireless video transmitter and receiver:
Long range cofdm army wireless video transmitter and receiver is a new design ultra-low latency COFDM digital video transmitter from Shenzhen Safe Guard. Designed with 3 video ports, HDMI, SDI, and BNC on the transmitter, which is perfect for analogue or digital cameras.
With 4th generation COFDM, narrow-band, and H.264 encoder technology as its code, long range cofdm army wireless video transmitter and receiver sends high definition images ideal for establishing rugged wireless video links in different environments, like mobile and urban environments. The compact design and low consumption make this HD transmitter enable true long range HD video transmission.
Special features of long range cofdm army wireless video transmitter and receiver:
* support 3 video input formats (interfaces): HDMI, SDI, BNC
* strong safety with AES user-defined passwords
* compact design, low consumption and low latency
* support NLOS and fast moving environments but stable signals transmission
* easy operation by digital panel configuration, and LCD display
* designed in military-grade level
