COFDM Vehicle Mobile Modulater AV sender

Description:  

ST-6000TJ20F COFDM Modulator is the ideal solution for establishing rugged wireless video links in all environments including high-speed motion and urban environments. Especially, the latest technologies of COFDM modulation and MPEG-2/MPEG-4 video compression ensure high quality of NLOS (non line-of-sight) transmission. This system is high-powered and can realize longer transmission range with stable, real-time and high definition images. This product can be mounted in a car or helicopter to transmit real-time audio and video to the commanding center. 

Product Application and Features:

* Inset high-powered amplifier and cooling fans* Stable transmission with omni-directional antenna* COFDM modulation and MPEG-2 video compression* Adjustable working frequency, LCD board displays the working frequency * Great security by encryption of AES 128 bit/ALLTECH Basic Scrambling* Rack mountable design, can be installed in a car or helicopter* Good transmission with high definition image and stereo audio* Stable transmission in NLOS(non line-of-sight)and high speed mobile condition.* The transmission range is 3-50km in NLOS(non line-of-sight)condition and more than 50km in LOS(line-of-sight)condition

 

In the urban and mountainous environments, the vehicle mountable wireless video transmitter is suitable equipment that can realize the NLOS (non line-of-sight) transmission and can work well in high-speed mobile condition. Furthermore, this system is high-powered and can meet the requirement of longer-range transmission (3-50 km in NLOS condition).
