The present application relates to the field of security and protection, and provides a pan-tilt control method, device and system. The method comprises: detecting whether there is a signal source within a monitored region of a pan-tilt camera, the pan-tilt camera comprising a pan-tilt and a camera attached to the pan-tilt; judging, when there is a signal source within the monitored region, whether signals emitted from the signal source are position adjusting signals for indicating a position adjustment on the pan-tilt; and adjusting a position of the pan-tilt according to a position of the signal source when the signals emitted from the signal source are position adjusting signals. In the present application, the trigger delay of the control operation on the pan-tilt camera is reduced.

Techniques are described for using an integrated lightbulb camera system for monitoring a property. The integrated lightbulb camera system can have a housing that includes one or more cameras, a power-line communication (PLC) chip, and one or more processors. The PLC chip can be configured to enable communications between the lightbulb camera system and one or more external devices. The one or more processors can be configured to control the one or more cameras to capture one or more images and control the PLC chip to transmit at least one of the one or more captured images over a power-line to at least one of the one or more external devices. The integrated lightbulb camera can also have a lightbulb compatible screw base that is configured to mount the housing to a lightbulb socket and accept electrical current that is provided to the housing.

A closed circuit television (CCTV) system includes a camera, a recorder, and a power supply circuit. The camera is arranged to capture an image. The recorder is arranged to receive the image from the camera and store the image. The power supply circuit includes a transforming circuit, a first output port coupled to the camera, a second output port coupled to the recorder, and a voltage source. The transforming circuit is arranged to generate a direct current (DC) voltage by converting an alternating current (AC) voltage. The voltage source is arranged to be selectively charged by the DC voltage, and selectively provide a first DC current to the camera via the first output port and a second DC current to the recorder via the second output port.

An image processing system includes a dual lens module and a processor. The dual lens module captures a pair of images. The processor generates a depth map of the pair of images. The processor generates a pixel depth distribution histogram according to the depth map. The processor calculates a pixel depth mean and a pixel depth variance according to the pixel depth distribution histogram. The processor determines whether the pixel depth mean is within a distance range and determines whether the pixel depth variance is smaller than a first threshold or larger than a second threshold, so as to determine that the dual lens module is situated in a normal state or an abnormal state.

Provided are a camera assembly and a method of installing the camera assembly. The camera assembly includes: a base portion; a guide rail mounted on a surface of the base portion; a magnet arranged to face the guide rail; a camera lens units arranged to be moveable on or along the guide rail; and a cover configured to fix positions of the camera lens units to the guide rail by pushing at least one of the plurality of camera lens units.

A polygon monitoring camera with multi-functional mounting structure has a housing, a first assembling surface and a second assembling surface. A camera module is provided within the inside of the housing. The first assembling surface formed on either side of the housing is configured to fix an mounting module thereon; while the second assembling surface formed on another surface of the housing is configured to install additionally a fixing unit configured to fix another mounting module or a second polygon monitoring camera that is identical in appearance and contains a depth camera module. In this manner, manufacturers can customize the mounting modules required for different user according to their actual needs, and solve the problem that the conventional multi-functional cameras cannot meet the requirements of customized design due to different specifications of the camera, and present disclosure can achieve increased functions of a single camera in flexible manner.
