Drone Detector, with its ability to use radio frequency detection, can currently spot a drone at up to a one kilometer distance. This is GPS-based, and it allows the user to not only detect a drone but also to find its operator, which is very important to law enforcement.
The only detector on the market with “friend or foe” identification, Drone Detector is designed for ease of installation, and it keeps detailed intrusion logs. Drone Labs plans to add video, thermal, and radar capabilities.
