An image recognition-based intelligent alarm lamp includes a lighting device, a rotating mechanism, a high-definition camera, a DC motor, an LED alarm lamp and an embedded processing device. The lighting device is mounted onto the rotating mechanism and rotated with the rotating mechanism to illuminate an object from different directions; the DC motor is coupled to the rotating mechanism for driving the rotation of the rotating mechanism; the high-definition camera is provided for capturing a video stream around a police car; the embedded processing device is provided for receiving an image around the police car, determining whether or not to send a rotation drive signal to the DC motor based on the image around the police car, and determining a flashing method of the LED alarm lamp based on the image around the police car. This invention improves the level of recognizing a criminal around the police car.
