VB源码：海康登录窗口，视频监控相关实例，实现了查询各路图像，测试编译前请将最新的网络sdk放在程序目录下面，否则程序可能达不到预期功能，测试界面截图如下图示。源代码内涉及了IPC获取CCD参数配置、获取抓拍机IO输入参数、设置IO闪光灯输出参数、获取单IO触发抓拍功能配置、输入的IO口状态，0-下降沿，1-上升沿，2-上升沿和下降沿，3-高电平，4-低电平、红绿灯功能（2个IO输入一组）、测速功能、白平衡配置等相关编写要点。-vB Source: Kang login window, video surveillance-related examples and achieve a query brightest image, please test before compiling the latest network sdk directory on the program, or the program may not reach the intended function, as shown below screenshot test interface . Within the source code related to the IPC for CCD parameter configuration, IO input parameters for capturing machine, set the flash output parameters IO, IO trigger the capture function to obtain a single configuration, the input of the IO port status 0- falling, one- rising 2- rising and falling 3- high 4- low traffic light function (2 IO input a set), speed function, white balance and other related written configuration points.
