SEB1 Ethernet UDP COFDM Transmitter Module

    -- One-way Ethernet UDP data COFDM wireless transmission
    -- Support uart data too
    -- Embedded RTSP video client to get video from IP camera via Ethernet connection
    -- Wireless transmission delay less than 10ms

SEB1 Ethernet COFDM module accepts data from Ethernet port and transmits out. It can pair with SHD1&DR2C (or SHD4&DR2C, SEB1&DR2C) to implement one-way Ethernet/uart UDP data COFDM wireless transmission.

Features:

• COFDM modulation
• Stable signal transfer in NLOS and high speed moving;
• Adjustable working frequency, band width, transmission power, etc;
• Ethernet/uart connection for IP data/uart data UDP broadcast transmission;
• Maximum 31.67Mbps wireless transmitting bitrates;
• Embedded RTSP video client to get video from IP camera via Ethernet connection;
• Wireless transmission delay less than 10ms;
• Great security by AES256 encryption.

One-way Ethernet UDP transmission paired with COFDM receiver module

IP camera video Transmission: SEB1 can get video from IP camera via Ethernet connection with built-in RTSP client and transmit out, on the COFDM receiving side, our COFDM module has built-in RTSP Server to enable video streaming over Ethernet for remote software or hardware decoders.
