Constant Surveillance Tethered Drone
Kapri Corp has emerged as a highly reliable manufacturer and supplier of Constant SurvilanceTethered Drone. A tethered drone is a type of unmanned aerial vehicle (UAV) that remains connected to a ground station via a physical tether, usually a cable. This tether provides power and sometimes data communication, enabling the drone to remain in flight for extended periods, much longer than battery-powered drones.
This drone is commonly used in applications where continuous, real-time surveillance, communication relay, or monitoring is required, such as in security operations, disaster response, and event management. The tether also ensures a more secure and stable flight, as it limits the drone’s range and altitude, and reduces risks like signal interference or battery depletion.

Technology of Constant Surveillance Tethered Drone
Tethered drones use a combination of advanced technologies to maintain stable, long-duration operations:
- Power Transmission Technology: The tether cable supplies continuous power from a ground station to the drone, allowing it to fly for extended periods without relying on batteries. The tether often uses lightweight, high-voltage cables to reduce weight and power loss.
- Data Communication: The tether can also serve as a communication link, transmitting high-bandwidth data such as video feeds or sensor data in real-time. This ensures secure and stable data transfer, free from wireless interference.
- Autonomous Flight Systems: Tethered drones often incorporate autopilot systems with GPS, inertial measurement units (IMUs), and other sensors for stable hover and automatic altitude adjustment, especially in windy conditions.
- Tether Management: Tether deployment and retraction systems, motorized, ensure the cable remains untangled and allows for controlled takeoff, flight, and landing.
- Durable Materials: Tether cables are designed with lightweight, flexible yet durable materials to withstand environmental stress and prevent breakage, built with strong weather-resistant frames to handle prolonged use in varying conditions.
