ZKManet2421UM is a compact and portable airborne device with HD and stable image quality. It adopts the current leading OFDM modulation technology, allowing for capturing high-quality images in high-speed motion and real-time transmission over non-line-of-sight (NLOS) conditions. During transmission, encryption is applied to the images and data, supporting frequency hopping at 800MHz, 1.4GHz, and 2.4GHz, with a transmission rate of 30Mbps and a range of 5-15KM for air-to-ground transmission. It is well-suited for long-term and high-data-flow wireless transmission applications.

* Range up to 5~15km(LOS)
* Supports 3 bands (800MHz/1.4GHz/2.4GHz)
* Supports FHSS
* IP transparent data transmission
* Compact size and light weight
* Rugged aluminum alloy housing
* Low power consumption
