Product Description
The high-definition image mobile vehicle terminal transmitter is a powerful and stable mobile image transmission system newly developed by our company. This system has the functions of image transmission and data return. Both the image signal and the sound signal have the function of AES encryption. Only the corresponding decryption receiver can receive and demodulate the signal sent by the transmitter. Even if the receiving frequency of other receivers is the same as the transmitting frequency of the transmitter, the signal transmitted by this transmitter cannot be demodulated. Effective Prevent illegal reception of signals.
The transmitter supports multiple input modes, supports H.265 encoding and 1080P high-definition digital video signals.
The transmitter has a data transmission function and can be equipped with other equipment, such as climate collection, temperature monitoring and other equipment. It can be input through the data communication port of the transmitter, transmitted through radio frequency signals, and demodulated its data content through the receiver in the command center.
