1W COFDM HD One Way Mini Wireless Transmitter , Video Wireless Transmitter
COFDM Transmitter Introduction:
1. Small, light, use H.264 encoding scheme and COFDM digital modulation mode, provide 720 * 576 high-definition video, great diffraction ability, support non-line of sight transmission, can be put in brief case, can transmit the live image to the rear people when secretly visit or obtain evidence. It is mainly used in public security, procurator, law, security bureau, other departments, etc.COFDM Transmitter.
2. Based on standard COFDM modulation technology, high-quality digital video
processing and H.264 video coding and decoding, very low delay of coding, support
high-speed mobile transmission, support the non-line of sight (NLOS) transmission,
support adjustable frequency (the frequent segment can choose UHF, 1.9 G~2.4GHz
etc.), small size and light weight (as cell phone size), the transmission distance is over500M under the non-line of sight environment. The video is clear and
stable,has no mosaic or drag phenomenon. All the frequency segment of receiver can be modulated continuously, and can also be modulated at customers’ location.
