Detailed Product Description
Product Name: 100 Km Long Range Wireless Video Audio Transmitter Receiver Modulate: COFDM
Frequency: 300-900Mhz Or Other Frequency Customized Video Input: HDMI/SDI; CVBS
Encryption: AES 128 Bits Video Resolution: 1920*1080P/I@60fps; 1280*720P/I@60fps

DS-HDT20W is a new arrival digital wireless video audio transmitter which adopts the latest technologies of COFDM modulation and H.264 image compression that enables good NLOS (Non line-of -sight) transmission with DVD quality video. The transmitter is compact size with strong power amplifier for longer-range transmission. Good heat resistant with two cooling fans. Be safety with AES128 bits. It works well in fast-moving transmission.

COFDM series long-distance high-definition image transmission radio is very suitable for reconnaissance, public security/firefighting/traffic/emergency rescue, customs border defense/maritime surveillance inspection, real-time broadcast/on-site monitoring, power line inspection/pipeline inspection, plant protection and other drones and unmanned aerial vehicles. Human-machine, industrial and commercial drones, and high-end consumer drones are suitable for high-quality real-time mobile video transmission in various complex environments such as cities, sea areas, and oceans.

Subway through-the-ground wireless communication
In view of the special underground environment of the subway, in the subway station, a wireless multi-hop network is quickly deployed and constructed through a network topology that combines chain relays and mesh, and relay relay transmission effectively solves wireless signal obstruction and realizes the connection between the ground and the underground. Penetrating wireless communication provides reliable, stable, and high-speed communication guarantee for station staff.

In the subway application scenario, traditional network laying and maintenance costs are high and the mobility and scalability are poor. The wireless MESH network is easy to deploy, flexible to use, and simple to operate. It can not only effectively reduce network construction and operation and maintenance costs, but also meet the needs of workers to move freely according to work tasks. It can also flexibly adjust and deploy video surveillance nodes to avoid monitoring blind spots.

The centerless, all-IP MESH broadband system is self-organizing and self-healing. The network is highly robust and invulnerable. It can still work normally without any nodes. It can be used as a coverage extension of the existing wireless communication private network in the subway to achieve integrated communications. , and can also be used as an emergency backup transmission guarantee when a partial failure occurs in the operator's public network in the subway.
