Backpack Wireless COFDM Video Transmitter
Introduction:
The product is developed with COFDM technology and designed specially for the transmission of audio and video data. The COFDM modulation and MPEG-2 video compression guarantee the stability and quality of the transmission. The AES 128 bit encryption and ALLTECH Basic Scrambling ensure the transmission security. In addition, the feature of voice intercommunication strengthens the function and utility of the system. By voice intercommunication, the first responder can get dictation from the commanding center. This product is the ideal solution for NLOS (non line-of-sight) transmission and widely applied 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.
Product Application and Features:
Voice intercommunication
Inset high-performace power amplifier
Stable transmission with omni-directional antenna
Great security by encryption of AES 128 bit/ ALLTECH Basic Scrambling
Mobile and NLOS(Non line-of-sight) transmission
Aluminium casing with built-in cooling plates, waterproof and shockproof
