If you need these features, you must invest in a Hikvision NVR or a camera that specifically supports VCA. Otherwise, continue using standard continuous or motion-recorded playback, which will work without error.
) 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 Outdated Firmware
Your software sent a login request to the Hikvision device, but the device did not respond within the expected time (usually 5–15 seconds). The device may be offline, blocked, or ignoring the request.
What to look for:
Ensure that the appropriate smart feature (such as Smart Event or Face Capture ) is allocated and enabled.
Not all Hikvision devices support all ISAPI endpoints. Before calling an endpoint, verify that your specific device model supports the function. Error 23 in ISAPI contexts typically indicates endpoint incompatibility rather than network or authentication issues.
Save the settings and restart the storage server to clear the error. 2. Update Firmware and SDK Libraries hikvision error code hcnetsdkdll 23 better
If a specific ISAPI endpoint is not supported, consider implementing the required functionality through the standard SDK API (HCNetSDK.dll) instead.
Lower the resolution, frame rate, or compression (e.g., from H.265 to H.264) to reduce the load on the system. Summary Checklist for Long-Term Stability Why it works

Understanding the root cause is necessary for a "better" fix than just restarting the software.
: Check the specifications of your camera or NVR. If you are trying to use features like VCA or PTZ, ensure your specific model supports them. Check the SDK documentation to see if a
To find event footage on non-VCA hardware, avoid the "Event Playback" tab. Instead, utilize the panel, pull the full timeline, and look for highlighted motion bars manually. 2. Save Video Parameters Failed (Resolution & Codec Crash)
