Almost all freely available drones use radio signals. On the one hand, they receive commands from the remote control, on the other hand they send data such as video images or telemetry, e.g. position or remaining battery power, to the remote control.
Dedrone's market-leading radio frequency (RF) sensors receive and analyze these signals and are able not only to reliably detect drones, but also to classify them - i.e. identify the manufacturer and/or model - and locate them. This applies to almost all commercial, hobby and home-made drones and the entire DJI product line.
The RF-160 forms the basis of the sensor network and is also ideal for an initial risk analysis. In combination with several RF-300s, drones are not only detected, but also located and tracked.
The RF-160 with increased range and integrated LTE has been available since January 2020. You can still purchase the predecessor model, the RF-100.
