Key Specifications
It’s a new powerful HD COFDM video transmitter, can up to 15-25W RF power which supports transmitting over a long distance. With 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 a strong power amplifier for long range transmission. Good heat resistant with two cooling fans. Be safety with AES128 bits. Can work well in fast-moving transmission.

Suitable for vehicles - cars, boat - boats, cars - a building, ship – a base station, aircraft –a building/vehicle and etc. high-definition moving video signal transmission, the carrier velocity greater than 450 km / h. Widely used in public security, armed police, fire, field armies, other military departments and broadcasting, urban management, civil defense, transportation, customs, oil, mining, water, electricity, geology, finance and other relevant state departments.
