: If the error appears when trying to decrypt or access a stream, it may be related to a missing or incorrect stream encryption password.
Specifically, Hikvision SDK Error Code 23 is generally defined as "The device does not support this function" or is related to an invalid channel or parameter configuration during the verification phase. In many practical scenarios, this error manifests when the user tries to view a camera channel that does not exist or is not properly mapped. For example, if an NVR has 8 physical channels but the software attempts to verify or stream channel 9, the SDK returns an error indicating that the requested resource is invalid. The "verified" aspect of the user query often implies that the user is attempting to verify the device password or connectivity parameters. In this context, the error suggests that while the device might be reachable, the specific verification request is formatted incorrectly or targets a non-existent element within the device's logic.
When a legacy Hikvision device is paired with a modern version of iVMS-4200, the software may expose newer configuration toggles that do not exist within the older camera's API framework. Trying to apply these ghost settings results in a support mismatch.
