Work with COFDM Video Transmitter

 

The C328 transmitter is a mini COFDM video transmitter from Wireless LinkAV, designed specifically for covert video installation applications. With proven LinkAV COFDM technology at its core, the small size and low power consumption of the C328 Transmitter make it the product of choice for covert video hides, or applications requiring long term battery power deployments, small unmanned aerial vehicles, and body-worn use. The C328 Transmitter employs low latency High Profile H.264 (MPEG-4 ) encoding for excellent image quality retention over the wireless link. Equipped with integral COFDM modulation, it is ideal for establishing rugged wireless video links in numerous environments, including mobile and urban. Offering several user-selectable modes that trade off image quality against range, it is very well suited to all mission types. Security is ensured with optional AES128/256 Encryption. C328 transmitter will transmit images in a non-line of sight environment up to 1km, depending on mode and frequency.
