ZKMANET2421UM Customized Data Link IP OFDM Video Transmitter for Drone UAV VTOL

ZKManet2421UM is a compact and portable unmanned carrier device with high definition and stable image quality developed by our company. Adopting the current leading OFDM modulation technology, it can realize shooting and real-time transmission of high-quality images in non-line-of-sight (non-visual), high-speed movement, encrypting images and data during transmission, and supporting frequency hopping at 800MHz, 1.4GHz, 2.4GHz, transmission rate of 30Mbps and 5-15KM air-to-ground transmission, which is very suitable for long-time and high-dataflow wireless transmission applications.

1. IP data transparent transmission;
2. Support webcam access;
3. Long transmission distance, line-of-sight 5-15km;
4. Supports transmission at 800MHz, 1.4GHz, 2.4GHz frequency hopping;
5. Small and portable design, aluminum alloy with good thermal conductivity, impact resistant;
6. Supports unicast, multicast, and broadcast propagation methods, and any node can communicate with each other using these three methods.
 

Compact Size

The transmitter is compact and lightweight, with a total weight of 124g, effectively reducing the drone's payload and enhancing its wind resistance in the air.

High Reliability

The system employs advanced Orthogonal Frequency Division Multiplexing (OFDM) modulation technology, which has strong anti-interference capabilities. It also uses AES encryption technology to effectively prevent interference and eavesdropping.

Strong Usability

Quick deployment without configuration is possible, and the system operates stably and reliably with simple maintenance.

Long Transmission Distance

Utilizing the drone's flight altitude and servo antenna tracking directional antenna technology, the transmission distance can be guaranteed at 15, 30, or longer kilometers, while the system also possesses strong diffraction and penetration capabilities.

Clear Image Transmission

The system uses H.264/MPEG-2/4 compression methods, allowing transmitted video to achieve 1080P quality, clearly presenting images captured by the drone to the user.

• 1. Power Cables - power supply input line, red is VDD, black is GND
