A system for detecting and extinguishing fires occurring within a predetermined observation area in response to commands received from a monitoring center. The system includes a source of fire retardant liquid and a monitor for selectively directing liquid to the observation area. A valve is disposed in fluid communication between the source and the monitor and is selectively movable between a closed position wherein liquid is prevented from flowing through the valve, and an open position wherein liquid can flow through the valve. An infrared camera generates a signal in response to temperature changes occurring in the observation area. A network switch is provided for communicating with the monitoring center. A control unit in communication with the valve, the camera, and the network switch relays the signal to the monitoring center and moves the valve between the positions in response to commands received from the monitoring center.

A secure enclave may be used to satisfy privacy requirements and audit requirements. Code may be loaded into the secure enclave. The code may generate a predefined report based on data and added noise. The pre-defined report may be subject to audit requirements. The data may be subject to the privacy requirements. The secure enclave may generate an encryption key and a decryption key based on the code. Only the secure enclave may have access to the decryption key. And the secure enclave may allow only a verified copy of the code to access the decryption key. With the added noise, the report may satisfy a pre-defined differential privacy guarantee. Encrypting the code and ensuring that the report satisfies the differential privacy guarantee may satisfy the privacy requirements. Retaining the report, the code, the secure enclave, and the encrypted data may satisfy the audit requirements.

A fire extinguishing device is configured to, in response to a location signal from a fire detector: move to a first reference location; detect a fire and generate a thermal image, and calculate a target direction based on a line of sight and the thermal image; rotate such that the line of sight is aligned with the target direction, and detect the fire and generate a first reference image; move in the target direction to a second reference location, and detect the fire and generate a second reference image; calculate a distance to fire and a height of the fire; move to a location within a predetermined range from the fire, move a tube to a spraying position based on the height of the fire, and discharge an extinguishing agent.
