High power Vehicle-mounted COFDM the remote wireless video transmission
Introduction:
The vehicle mountable wireless video transmitter 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 80km 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).
