LA-HA6800DB High List Bing Two-way Voice Wireless Video Transmission System

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

  LA-HA6800DB High-listing bidirectional voice wireless video transmission system adopts COFDM (Coded Orthogonal Frequency Division Multiplexing) modulation technology. It has a narrow transmission band and strong anti-multipath interference capability, which can realize Non-line-of-sight (NLOS), shooting at high speed and transmitting high-quality images in real time Two-way intercom function makes live command more flexible.

The system adopts the H.264 digital video coding standard, and outputs high-definition HD1080P image quality with a resolution of 1920 * 1080 (backward compatible with 1080I, 720P, 480P and standard definition).

Widely used in military reconnaissance, border defense patrol, public security (including fire protection, forest fire protection, traffic police), civil air defense emergency, water conservancy and flood prevention, environmental protection monitoring, power inspection, railway rescue, maritime law enforcement, urban management law enforcement, construction site / wharf / oil field monitoring, television broadcast , Health and epidemic prevention or emergency command. It is suitable for real-time mobile video transmission in urban, sea, mountain and other complex geographical environments.

Applicable to individual soldiers ~ mobile command vehicles, individual soldiers ~ command monitoring center.
