Wireless remote Surveillance System

Vistelli Wireless Remote Surveillance System uses latest wireless transmission and multiplexing technology COFDM 2K QPSK (multi-carrier transmission technology) combining with digital video compression encoding-decoding processing (MPEG-2, MPEG-4 format) technologies to achieve real-time, synchronous mobile transmission of broadband multimedia services such as audio, video and data in high-speed mobile environment.COFDM is the most advanced modulation-demodulation technology today. It is resistant to multipath interference effects because it uses multiple carriers (1704 sub- carriers) to transmit the same signal. It has high penetration and diffraction abilities ( the bending of waves around obstacles and the spreading out of waves passing through small openings) , making it a good choice for wireless transmission under the non line-of-sight environment with barriers. COFDM is able to achieve wireless real- time transmission of high bit-rate, high quality audio and video signals under high speed motion environment. Hence, it can easily realise the audio & video transmission from stationary to mobile and mobile to mobile stations.
