The storage dithering occurs for a multi-channel video surveillance system with a traditional loop-testing mode when one hard disk space is not enough and the storage path changes. 采用传统的轮巡式视频监控系统在多路存储情况下,存在着存储的效率低下、因硬盘空间不足改变存储路径而造成的存储抖动等问题。
The new video surveillance technology will be used more easily and neatly, and it will bring the new functions including long-distance surveillance and hard disk storage. 新的视频监控技术将带来更好的易用性、更高的灵活性以及远程监控、硬盘存储等新功能。
Based on the requirements of digital video surveillance and recording applications, a portable digital video recorder is designed and developed. The system uses dedicated IC chips for real-time video compression, embedded microprocessor for system control and large capacity IDE disk or flash memory for storage. 针对各类视频监控和记录的应用特点和要求,设计并研制了一个基于嵌入式微处理器、专用视频压缩芯片及大容量IDE硬盘或电子盘的便携式数字录像机。
