WEB CAMERA SYSTEM BASED ON B-CDMA WIRELESS COMMUNICATIONS

摘要

A web camera system based on B-CDMA(Broad band Code Division Multiple Access) wireless communications is provided to check a scene and search a stored video data easily by modulating the control data of a controller and the image data of the encoding part into a B-CDMA wireless signal and transmitting the B-CDMA wireless signal to a remote control server through a wireless network. A CCD(Charge Coupled Device) module(110) receives an optical signal of a monitoring target area from a CCD camera lens(111) and generates an image signal in a low level. An image signal processor(120) processes an image signal inputted from the CCD module and generates a digital image signal. A sound signal processor(130) processes a sound signal inputted from the monitoring target area from an audio microphone and generates a digital audio signal. An encoding part(140) receives a digital image signal from the image signal processor. A display part(160) displays an operated state and a present state of a controller(150). A camera driving controller(170) controls the CCD camera driving motor based on the control of the controller and changes an area where a camera module is photographed. A B-CDMA connecting part(180) modulates the control data of the controller and the image data of the encoding part into a B-CDMA wireless signal and transmits the B-CDMA wireless signal to a remote control server through a wireless network. A LAN connecting part(181) is connected to the server over the internet.
