LA-A6800CZ-S SD Car-mounted Two-way Voice Wireless Video Transmission System

Main Products: wireless monitoring, wireless monitoring equipment, wireless video transmission, wireless monitoring system, wireless video monitoring

          无线视频传输系统采用 COFDM coded orthogonal frequency division multiplexing :编码 正交频分复用)调制 / 解调技术,具有传输频带窄( 2/2.5/4/8MHz )和很强的抗多径干扰能力等特性,能够实现非视距( NOLS ),高速运动情况下拍摄并实时传输高质量图像。 The LA-A6800CZ-S wireless video transmission system uses COFDM ( coded orthogonal frequency division multiplexing ) modulation / demodulation technology, with a narrow transmission band ( 2 / 2.5 / 4 / 8MHz ) and strong resistance. Multi-path interference ability and other characteristics, can achieve non-line-of-sight ( NOLS ), high-speed motion shooting and real-time transmission of high-quality images. Equipped with a two-way voice call function, greatly enhancing the flexibility of field command.

The system adopts H.264 / MPEG-2 audio and video compression standards, the resolution reaches DVD resolution (720 * 576 @ PAL / 720 * 480 @ NTSC), and the image is clear and smooth.

Can be used in public security, fire protection, traffic police, civil air defense emergency, urban management law enforcement, environmental protection monitoring, three defense emergency, water conservancy flood prevention, power rescue, railway rescue, maritime law enforcement, sea surveillance inspection, customs border control, terminal monitoring, forest fire prevention, oil field anti-theft, Military reconnaissance, TV broadcasting, etc.

Can be used to direct the command vehicle to the command center or relay to expand the monitoring radius and other applications.



■ Synchronous input of audio and video signals, omnidirectional antenna transmission

■ Non-line-of-sight (NLOS) \ High-speed motion transmission

■ Built-in air-cooled heat dissipation device to solve the heating problem of high-power equipment

■ Using OFDM modulation technology and MPEG-2 image compression technology

■ The straight line transmission distance is not less than 100km under the sight condition, and 3-50 km under the non-sight condition
