: When adding a camera to an NVR, this error can pop up if the parameters (like protocol or port) are set incorrectly for that specific channel. Try adding the camera manually using its specific IP rather than relying on "Plug and Play." Related Error Codes for Context Sometimes users misread or encounter these similar codes: : Insufficient permissions (try logging in as 'admin'). : Maximum connection limit reached (reboot the device).
Remember that error code 23 is fundamentally different from network or permission errors. If your device does not support the function, no amount of network tweaking or permission changes will resolve the issue. Instead, focus on upgrading equipment or adjusting functionality expectations to match your device's actual capabilities. hikvision error code hcnetsdkdll 23 better

While less common for error 23 specifically, in some implementations (especially with platform registration), error 23 can indicate network issues such as a wrong IP address, blocked ports (80, 554, 8000), or device time synchronization problems.
For developers, mixing 32-bit and 64-bit versions of the SDK with your Java, C#, or C++ project is a leading cause. The HCNetSDK.dll file must match the "bitness" of your application. If your program is compiled as 32-bit but you are using a 64-bit DLL, the system cannot load the library and will throw a loading error. One CSDN user reported spending two full days resolving a similar HCNetSDK loading issue caused by JDK and DLL bitness mismatches.
Discrepancies between the core features embedded within older firmware builds and newer versions of management software often trigger generic HCNetSDK.dll operation errors. He even checked the network cables
