Many "Not Supported" errors are simply software translation bugs between old firmware versions and newer client interfaces.

Before we fix the error, we must understand the battlefield.

The standard iVMS installer often includes an older hcnetsdk.dll . You need the correct version.

) is sent to a device that doesn't support that specific version or command. Check the SDK documentation to see if a legacy command is required. Outdated Firmware hikvision error code hcnetsdkdll 23 better

To quickly summarize the most effective solutions for resolving error HCNetSDK.dll[23] :

This occurs when a user or a background process attempts to execute a command—such as a specific PTZ movement, a VCA (Video Content Analysis) search, or a recording mode—that the hardware's firmware is not built to perform. 3. Common Scenarios

: Ensure both your iVMS software and the camera/NVR firmware are up to date by checking the Hikvision Support Portal.

The buffer was overflowing because the camera was trying to render something that didn't fit in a three-dimensional color space. It was trying to render a shape that existed in a higher resolution than reality allowed.

Bypass iVMS-4200 entirely. Input the camera's local IP address into a web browser. Try modifying the settings directly from the device's native web dashboard. If the option is greyed out or missing here, the hardware physically lacks the feature you are trying to use. You need the correct version

: Verify that your NVR or storage server supports the specific "Smart Event" or "VCA" feature you are trying to use. If it doesn't, you must use standard recording templates instead.

Sometimes the error is triggered by trying to pull a stream type that doesn't exist. Switch Stream Types : Try changing from the Main Stream to the Sub Stream Reset Parameters

If you are using Hikvision's ISAPI interface for device integration, error 23 appears as "Device does not support this function" when requesting information from endpoints like /ISAPI/System/deviceInfo or /ISAPI/System/IO/outputs . The issue is that some devices simply do not support these particular ISAPI calls.
