摘要
提出了一种居住小区闭路电视监控系统设计方案 .该方案采用视频捕捉技术 ,用视频捕捉卡获取动态视频信号 ,对视频信号进行数字化处理并存储于计算机硬盘中 ,由设备驱动程序读取并进行显示 .系统利用楼宇可视对讲系统的CCD摄像机作为监控设备 ,使系统资源得以充分利用 .与传统的模拟式闭路电视监控系统相比 ,在图像的处理、显示与存储方面更加灵活 ,使用更加方便 ,并可节省价格昂贵的模拟信号存储设备和编辑处理设备 .所采用的视频捕捉卡支持黑白图像信号和彩色图像信号 。
A design method of Closed-Circuit Televisio n (CCTV) monitoring system for residential quarters is proposed. By means of the t echnique of video capture , dynamic video signals are acquired by video capture card. The video signals a re digitized and saved in computer hard disc, which can be read and displayed by the device drivers. The CCD camera of building calling system is used as monito ring device so as to make full use of the system resources. The system is posses sed of flexibilities in picture processing, video display and data storage, alon g with easy usage and low price compared with traditional analog CCTV monitoritn systems. The syatem upgrade is convenient because video capture card used suppo rts both black & white and color picture signals.
