    COFDM rf 2W 300-900MHz DVB-T Digital wireless police security video transmitter

    COFDM rf 2W 300-900MHz DVB-T Digital wireless police security video transmitter

    C321 wireless video transmitter,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.

    Our main products are COFDM, TDD and 4G wireless video transmitter & receiver, which are widely used in city security, forest fire prevention surveillance, harbor wharf video surveillance, construction sites surveillance, tunnel, oil field, UAV, automobile surveillance, etc.


    The C321 wireless video transmitters series are based on MPEG-II and H.264 encoding technology, the HD digital wireless video transmission equipment was first developed in 2011. The system uses 300-900MHz frequency, advanced COFDM, QPSK, QAM modulation technology, highly improves the transmission, disturbance and the combination of the image quality , the high transmission specifically comes to more than 5KM .


    • Low latency
    • Working frequency and RF bandwidth self-adapted within specified range
    • Separately workable and also compatible with external power amplifier
    • Low power consumption, small size and portable usage
    • IP camera compatible
    • Reliable Military Components
    • External lithium battery, easy operation and battery replacement
    • Mostly applied to Surveillance Systems for Security Departments

    C321 wireless video transmitter 's Product Features:

    The system is suitable for HD on live of sporting events, cultural activities, important events as well as aerial photography and so on.

    H.264 encoder makes a very fruitful refinement and improvement in the efficiency of encoding, reducing coding delay, algorithm optimization, anti-error rate and further improvement of the picture quality. Achieve the best video compression by the lowest Bit rate. Use the advanced video pre-processing technology and efficient video coding algorithm to provide high-quality, low-rate broadcast audio and video signals for digital television broadcasting system, mobile TV systems, IPTV system. Large output power (0.5W-- 2W), adjustable on site, long distance of transmission, good diffraction ability. The video is clear and stable, can be converted to seamless HD, has no mosaic or drag phenomenon.
