Product Description

Camera Mount COFDM Broadcast Video Transmitter Low Delay H.264 Encoding 300-2700MHz



The LKAV-C323H is a camera mount COFDM wireless video transmitter featuring high quality and low latency, ideally suits live video cameras. With COFDM and H.264 technologies at its core, it can support FHD video transmission up to 1-2km NLOS. The C323H camera-back transmitter from LinkAV is a COFDM digital video transmitter specifically designed to mount on professional camcoders and steadicam rigs.


Utilising class-leading RF technology and high profile H.264 encoding, the transmitter offers low delay, low power consumption, exceptional range and 40% lower bit-rates compared to legacy MPEG2 systems. This allows true HD transmission in a single 4MHz channel whilst using robust, lower order modulation.



■ Advanced COFDM modulation

■ High efficient H.264 encoding

■ Transmission range up to 1-2km NLOS

■ 60-100ms low latency

■ SDI+CVBS or HDMI+CVBS video inputs

■ AES256 encryption
