如何拍摄连接到DVR的相机？ [英] How to take a capture of a camera which Is connected to a DVR?

问题描述

你好;



我需要创建一个应用程序，它可以从连接到DVR的摄像机视频中捕获图像。 （例如：当我点击特定的btn时，应该将图像保存到我的客户端计算机，该图像应该从特定的摄像头拍摄，最后一张图像与DVR相关）



你能帮我这么做吗？我曾尝试做研究但没有成功..

推荐答案

根本不了解您的DVR，它的功能，无论您是否有SDK，文档，任何关于硬件的信息，除了更多的研究之外，不可能告诉您必须做什么。

Without knowing anything at all about your DVR, its capabilities, whether you have an SDK for it, documentation, ANYTHING AT ALL about the hardware it's IMPOSSIBLE to tell you what you have to do, other than more research.
