Embodiment Construction

[0054] figure 1 Shown is a schematic structural diagram of the first embodiment of the camera device of the present invention, the camera device includes a camera module 11 and a PLC camera adapter module 12 . Wherein, the camera module 11 is used to shoot audio / video information including audio, video, images, etc., and the PLC camera adaptation module 12 is used to receive the audio / video information taken by the camera module 11, that is, the audio / video information taken by the camera module 11 Modulate the information, load it into the power line and send it to the control device that controls the camera. At the same time, demodulate the modulated signal of the control signal sent by the control device through the power line, and control the camera with the control signal obtained after demodulation. The camera parameters of the module 11, such as: camera angle, focal length, sensitivity, and the media type of shooting such as video, picture, audio or audio / video combinat...

Abstract

The camera system includes camera equipment, control device and application server. Including camera module and PLC camera adaption module, the camera equipment is in use for producing audio / video information. The camera equipment modulates audio / video information, and sends out modulated information, as well as demodulates the modulated signal transferred from power line so as to obtain control signal, and adjusts parameters of camera shot. Control device is in use for demodulating the modulated signal of received audio / video information, and sends demodulated signal. Based on received control indication information, the control device generates and modulates control signal, and controls camera module. Application server is in use for storing, providing audio / video information, and other relevant information. The invention also discloses method for controlling camera shot. The invention can control camera equipment remotely without need of using dedicated signal line to connect to.

Description

technical field [0001] The present invention relates to a camera system and a camera control method, in particular to a camera device that can be remotely controlled by a mobile terminal and without a special signal line, a camera system composed of the camera device, and a remote control method for the camera device by a mobile terminal Methods. Background technique [0002] With the popularity of digital products, camera devices have become the preferred media for families and groups to record and store information. Users can record video, audio or mixed audio and video information through camera devices, which is very convenient. Existing camera systems usually consist of a camera device at the camera site and a control device for controlling the camera device, and are usually connected in two ways between the two: one is through a power line and a dedicated signal line (such as a video signal) at the same time. cable) connection, and the second is to connect through a d...
