ST-6000TKMD Buckle plate COFDM

Introduction:This product is a new kind of broadband wireless video equipment that adopts the latest technologies of COFDM modulation and MPEG-2 video compression that can complete video transmission in high-speed motion and NLOS (non line-of-sight) conditions. The diversity receiving technology greatly improves the receiving quality in all conditions. This transmitter is specially designed to meet all necessary transmission requirements of broadcasting standard .It has been widely used in many fields such as: Police Forces, First Responders, Security Services, Fire Services, Port Security, Homeland Security, Traffic Management, Police Technical Support Units, Special Forces, Military Command and Control Posts, Airport, Border Control, Major Incident Support etc.

Main Features:*Lithium battery for power supply*Convenient to be carried and installed*COFDM modulation and MPEG-2 video compression*Firm enclosure with built-in cooling fans, waterproof and shockproof*Great security by encryption of AES 128 bit/ALLTECH Basic Scrambling*Modular design and highly integrated*Good transmission with high definition image and stereo audio*Adjustable working frequency, LCD board displays the working frequency*Stable transmission in NLOS(non line-of-sight)and high speed mobile conditions. *The transmission range is more than 50km in LOS (line-of-sight) environment

 

Product Application:

This equipment can realize the wireless transmission with high definition video and stereo audio in NLOS (Non line-of-sight) condition. The first responder can carry the equipment to enter accident ground and then the transmitter send the camera's digital, compressed signals to the commanding center.
