LA-A6800DB SD two-way voice wireless image transmission system

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

The LA-A6800DB two-way voice 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 capability and other features can realize non-line-of-sight (NLOS) and transmit high-quality images in real time under high-speed motion. Two-way intercom function makes live command more flexible.

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

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 for individual launch ~ command vehicle or individual launch ~ command monitoring center and other applications.
