HCNetSDK.dll[23]
The Hikvision error code indicates that the requested function is not supported by the device or current firmware . This often occurs when using iVMS-4200 or an SDK-based application to perform a task the hardware isn't designed for, such as configuring PTZ on a fixed camera or searching for "Smart Event" playback on a device without Video Content Analysis (VCA). Common Triggers for Error 23
NET_DVR_DEVICEINFO_V40 devInfo; memset(&devInfo, 0, sizeof(NET_DVR_DEVICEINFO_V40)); LONG lUserID = NET_DVR_Login_V40((char*)ip, port, (char*)user, (char*)pass, &devInfo); if (lUserID < 0) DWORD dwErr = NET_DVR_GetLastError(); // Should be 23 // Check devInfo.struDeviceV30.byLockEnable for lock status

When integrating Hikvision devices (IP cameras, NVRs, DVRs) with third-party software (VMS, CMS, or custom applications), developers and system integrators often rely on the (Hikvision Network Software Development Kit). This dynamic link library handles device discovery, live view streaming, playback, and PTZ control.
