Abstract: A built-in explosion-proof net vehicle-mounted loudspeaker includes a safety protection device, a loudspeaker main body, an explosion-proof net container, a release device, and an embedded processing device. The embedded processing device is connected with the safety protection device, the loudspeaker main body, the explosion-proof net container and the release device, respectively. The explosion-proof net container is configured to accommodate an explosion-proof net. The release device is disposed at a rear end of the explosion-proof net container. When receiving a transmission control signal, the release device releases the explosion-proof net in the explosion-proof net container based on the transmission control signal. The safety protection device includes a vibration sensor connected to the loudspeaker main body for detecting a vibration value of the loudspeaker main body.

Abstract: A face detection-based bulb type alarm lamp includes a folding mounting base, an explosion-proof net container, a releasing device, a red bulb, a blue bulb, and a DSP chip. The folding mounting base is used for fixing the red bulb (4) and the blue bulb (5); the explosion-proof net container is used for containing an explosion-proof net; the releasing device is disposed at the rear end of the explosion-proof net container for use of release, when receiving an emission control signal, the explosion-proof net in the explosion-proof net container based on the emission control signal. The function of the bulb type alarm lamp is extended, thereby facilitating use by the police.

Abstract: A universal police speaker includes an inner cavity, a voice coil, a magnet, a support plate, a diaphragm and a protecting cover to form a dome speaker structure. The inner cavity is filled with a sound absorbing material; the voice coil is installed around the inner cavity; the magnet is installed around the voice coil; the support plate is installed between the voice coil and the magnet; the diaphragm is installed at the top of the inner cavity; and the protecting cover is installed at the diaphragm. The speaker further includes a level bracket for placing the inner cavity, the voice coil, the magnet, the support plate, the diaphragm and the protecting cover, and the level bracket is disposed at the top of a car body of a police car. The invention can improve the anti-violence capability of the police speaker.

Abstract: 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.

Abstract: A multifunctional automobile alarm lamp includes an LED lighting device, a lamp housing, a rod mounting base and a lighting control device. The LED lighting device is installed in the lamp housing; the rod mounting base includes a connecting rod, a connecting board and a fixing bracket; the connecting board is for connecting the lamp housing; the connecting rod is for connecting the connecting board; the connecting rod is connected to the fixing bracket by a sliding sleeve method; the fixing bracket is installed to the top of the police car at where the alarm lamp is situated; the lighting control device is connected to the LED lighting device for controlling the lighting method of the LED lighting device. The present invention can expand the application functions of the LED alarm lamp.

Abstract: Embodiments described herein may provide an intelligent warning lamp that provides image recognition features using an image capture device and a target analysis device offering high-precision results. The target analysis device may perform facial recognition on a detected human in a surrounding image to obtain a facial feature, and match the obtained facial feature with features of a known target. For example, in a law enforcement application, the intelligent warning lamp may match facial features of people nearby a police car with a known criminal. If the match is found, a successful identification signal may be issued with information about the target. The intelligent warning lamp may include an automated deterrent system. The intelligent warning lamp may operate to determine a relative position of the target based on the image data, and may eject a deterrent in the direction of the target using the ejection driving device.
