Product Info

The Fotokite Sigma is a professional, tethered drone system built for fire, police, and emergency response teams who need constant, reliable aerial visibility. Operating on a secure power + data tether, the Sigma can fly continuously for 24 hours without battery swaps, crew load, or piloting.
The system launches and lands at one button press, allowing responders to maintain full focus on the mission. Choose between Thermal 320p for standard situational awareness or Thermal 640p for enhanced detail and search work. Available in Transport Case, Rooftop Box, and Tray Mount vehicle-integrated configurations to fit any deployment workflow.

Key Features

1. Continuous 24-Hour Operation – Powered via the tether from vehicle or shore supply, enabling uninterrupted aerial overwatch during long-duration incidents without battery changes or pilot fatigue.

2. Autonomous Launch & Flight – Deploys at the push of a button with no piloting required, allowing responders to stay focused on the situation, not flying a drone.

3. 45m Secure Tethered Elevation – Always aviation-compliant with guaranteed airspace control and encrypted data transmission back to ground teams.

4. All-Weather Resilience – IP55-rated to perform reliably in rain, dust, snow, heat, and challenging emergency environments.
