NLOS LOS Narrow Bandwidth 2-8Mhz HD Wireless Transmitter for government video surveillance


COFDM Wireless Video Transmitter Specification:

The C321 transmitter is a body-worn COFDM video transmitter from wireless LinkAV, designed specifically for government video surveillance, Police law enforcement, border control, internal security, critical infrastructure protection, military command video transmission applications.


With the leading COFDM technology and H.264 encoder technology, the C321 transmitter enables viewers high definition images ideal for establishing rugged wireless video links in all environments including mobile and urban environments.


The integrate design makes the C321 transmitter ideal for applications requiring long term battery power deployments, it employs low latency High Profile H.264 (MPEG-4 ) encoding for excellent image quality retention over the wireless link. it is very well suited to all mission types. Security is ensured with AES256 Encryption. C321 transmitter can transmit video data in a non-line of sight environment up to 2-5km, depending on mode and frequency.


Using the leading COFDM modulation technology to overcome the analog technology and conventional modulation technology's limit of multipath reflection and occlusion, it can be achieved in the non-line of sight (NLOS), high-speed moving and real-time Transmission with high-quality images, especially suitable for complex environments.


The transmitter is with clear and stable image,intergrated design,double battery,perfect for NLOS transmission and mobile applications.

SD & HD compatible.
C321 with H.264/MPEG-2 video compression.
