COFDM-912T adopts advanced COFDM (multi-carrier modulation technology), which integrates transmitting antenna, digital modulation, and audio and video digital compression. It has a small size and long transmission distance. Modular combined design can be used with secret shooting clothes and small cameras, can realize hidden on-site high-definition image collection and transmission. It is a highly integrated mobile non-line-of-sight digital mobile video wireless image transmission equipment that can transmit real-time and stable audio and video in high-speed movement and under the condition of urban buildings.
The transmission system can reach a transmission distance of more than 500 ಮೀಟರ್ and a line of sight of more than 10 kilometers under general blocking conditions. Using high-gain directional antennas or omnidirectional antennas can further increase the transmission distance. If you need a longer transmission distance, you can use the existing wired network, mobile communication (satellite), and use our company’s portable relay transmission equipment or vehicle-mounted wireless video transmission system for relay transmission. The transmission distance of the system can be Reach more than 20 kilometers.
There are 2 different powers for the secret shot type equipment (0.5W and 1W@average power PA). The greater the power, the stronger the signal penetration and the longer the transmission distance.
ಸಂವಹನ ಅಂತರವನ್ನು: visual environment ≥ 2km. Blocking environment: ≥500m (different depending on the environment)
ವೈಶಿಷ್ಟ್ಯ
- Highly integrated, modular design
