⚠️ Only do this in secure local networks, as it lowers security.

Error Code: HCNetSDK.dll Error 23 (often displayed as "Error Code 23" or "SDK Error 23: Verified failed") Affected Software: Hikvision iVMS-4200, iVMS-5200, HikCentral, or third-party VMS using Hikvision SDK Primary Symptom: Device shows as "Offline" or "Abnormal," and login attempts fail despite correct credentials.

If you manage a Hikvision surveillance system—especially the iVMS-4200 client software—you have likely encountered the dreaded "HCNetSDK.dll Error 23 Verified" message. This error is notorious among security system administrators because it prevents adding or accessing cameras and NVRs (Network Video Recorders), effectively crippling your surveillance capabilities.

But what does "Verified failed" actually mean? In short, the Hikvision SDK (Software Development Kit) is telling your management software that the authentication handshake between the client and the device failed. Importantly, Error 23 is rarely a hardware failure. It is almost always a configuration or credential mismatch.

In this comprehensive guide, we will break down exactly what triggers error code 23, walk through verified solutions from Hikvision support forums and engineering teams, and show you how to permanently resolve the issue.


Hikvision releases SDK updates to patch encryption mismatches. An old client cannot verify a new device.

  • Update Device Firmware:

  • Expected result: After both updates, delete and re-add the device. Error 23 should resolve.

    Error code 23 verified failed almost always comes down to incorrect or blocked login credentials. Start by resetting the device password, then work through permission and SDK compatibility checks. In most cases, simply re-adding the device with the correct password resolves the issue.

    If none of the above works, perform a hard reset of the Hikvision device (press the reset button for 10+ seconds) and reactivate it with a new password.

    The Hikvision error code HCNetSDK.dll[23] 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

    Unsupported Features: Attempting to use PTZ controls on a camera that does not have PTZ capabilities.

    VCA Playback: Searching for recording files using "Event" filters on devices (like some NAS drives) that do not support Smart Events or VCA.

    Incompatible Stream Settings: Trying to change video parameters (like resolution or frame rate) to values not supported by that specific hardware model.

    Firmware Mismatch: The management software (e.g., iVMS-4200) attempting to use a newer protocol or command that an older firmware version does not recognize. Troubleshooting Steps Verify Hardware Capabilities

    Check your device's datasheet to ensure it actually supports the feature you are trying to use (e.g., Audio, PTZ, or Smart Detection).

    If you are receiving this error while trying to change settings, ensure the camera is not limited by the NVR's maximum supported resolution or bandwidth. Adjust Stream Settings

    In iVMS-4200, go to Device Management > Remote Configuration > Video & Audio.

    Ensure the Video Type is set to "Video & Audio" if you are attempting to use sound features.

    Try switching from "Main Stream" to "Sub Stream" to see if the error persists, as some functions only work on specific streams. Update Firmware

    Download the latest firmware for your specific NVR/Camera model from the Hikvision Download Center.

    Applying a firmware update can often add support for commands used by newer versions of iVMS-4200. Use Official Tools for Configuration

    If iVMS-4200 fails with Error 23, try configuring the setting directly through the device's web interface (using its IP address in a browser) or via the SADP Tool. Check Playback Filters

    When searching for footage, use the "Normal" recording search rather than "Event" or "VCA" if your storage device (like a NAS or basic SD card) doesn't support advanced metadata indexing. Summary Table: Error Code 23 Potential Cause Live View Stream type mismatch Change stream to "Video & Audio". Playback Searching for Events on non-VCA device Search for "Normal" recordings instead. PTZ Control Fixed camera used Verify if camera has physical PTZ motors. Settings Parameter out of range Use lower resolution or frame rate.

    Understanding Hikvision Error Code HCNetSDK.dll[23]: Causes and Verified Solutions

    Hikvision error code HCNetSDK.dll[23] translates officially to "Device does not support this function" or NET_DVR_NOSUPPORT. This error typically appears when using iVMS-4200 software to access advanced features—such as Smart Playback, VCA (Video Content Analysis), or PTZ controls—on hardware that lacks the necessary capability to perform those specific tasks. Primary Causes of Error Code 23

    The error is rarely a software "bug" in the traditional sense; rather, it is a notification that there is a hardware or configuration mismatch between the software's request and the device's capability.

    Unsupported Smart Features: Attempting to use "Smart Search" or "Smart Playback" on standard IP cameras or older NVRs that do not support VCA events.

    iVMS-4200 Storage Server Limitations: The iVMS-4200 Storage Server (PC-NVR) often triggers this error when users attempt to search for event-triggered video because the storage server itself does not process VCA data like a dedicated Hikvision NVR would. hikvision error code hcnetsdkdll 23 verified

    Mismatched Control Requests: Trying to use PTZ (Pan-Tilt-Zoom) functions on a fixed lens camera.

    Recording Template Errors: Specifically, switching a recording template to "Event" on a system where the device or storage medium is not configured to handle event-based metadata. Verified Solutions to Resolve the Error

    Because Error Code 23 indicates a lack of functional support, "fixing" it usually involves adjusting how you use the software or upgrading your hardware configuration. 1. Adjust Storage Quota Settings (For VCA/Smart Events)

    If you are using iVMS-4200 and believe your device should support smart events, the issue may be that the storage server has no space allocated for metadata.

    By default, Hikvision storage quotas are often set to 100% Video, 0% Pictures, and 0% Info.

    The server cannot store VCA or alarm information with a 0% quota.

    Verified Fix: Navigate to the storage server settings and modify the quota to something like 95% Video, 4% Photo, and 1% Information. 2. Use a Hardware NVR for VCA Features

    The iVMS-4200 PC-NVR (Storage Server) is a software-based recorder and lacks the dedicated processing power for complex Video Content Analysis found in standalone recorders.

    Verified Recommendation: If you require "Smart Event" playback, use a dedicated Hikvision NVR with built-in VCA support instead of the PC-based storage server. 3. Verify Account Permissions

    Sometimes, a lack of administrative privileges can masquerade as a "not supported" error if the operator account is blocked from accessing specific advanced settings. Ensure you are logged in with an Admin account.

    Check user management settings to ensure the current user has "Remote Playback" and "VCA Search" permissions enabled. 4. Check for Firmware Updates

    In some cases, a device may theoretically support a function, but the current firmware version does not communicate properly with the latest

    Visit the official Hikvision Support Portal to find the latest firmware for your specific camera or NVR model. Summary Table: Error Code 23 Scenarios Real-World Context Likely Result Smart Playback Using "Smart Search" on a basic camera. Hardware does not support VCA; feature is unavailable. PTZ Control Clicking directional arrows on a fixed camera. "Not supported" error appears immediately. PC-NVR Events Setting "Event" recording on iVMS Storage Server.

    The Hikvision error HCNetSDK.dll 23 (formally NET_DVR_NOSUPPORT) indicates that the device does not support the specific function being requested. This typically occurs in software like iVMS-4200 when a user attempts to perform an action—such as specialized event playback or changing certain video parameters—that the hardware is not capable of handling. Common Causes

    Unsupported Event Search: Trying to search for "Event" or "Motion Detection" recordings on a storage device (like a NAS or basic NVR) that lacks Video Content Analysis (VCA) capabilities.

    Parameter Incompatibility: Attempting to change high-level video settings (resolution, frame rate) on a device that doesn't allow those specific modifications via the SDK/client.

    Recording Template Mismatch: Using an "Event" recording template on an iVMS-4200 PC-NVR setup where the hardware does not support event-based storage. Solutions and Troubleshooting

    Verify Hardware Capability: Check the data sheet of your camera or NVR/DVR on the Hikvision Global Support site to confirm if it supports features like VCA, Smart Event, or specific video encoding types. Update Software and Firmware:

    Download the latest version of the iVMS-4200 Series software to ensure compatibility with newer device features.

    Update your device's firmware using the Batch Configuration Tool if web browsers or iVMS fail to apply settings.

    Adjust Stream Settings: If the error occurs during playback, try switching from "Main Stream" to "Sub Stream" (or vice-versa) to see if the recorder supports the specific encoding type.

    Check User Permissions: Ensure you are logged in with an Admin account. While Error 23 is usually about hardware support, lack of permission (often Error 2) can sometimes manifest as "not supported" in specific client versions. NAS drive and hikvision camera: Failed to search file

    Hikvision error code 23 (often appearing via the HCNetSDK.dll library) translates to "The input password is wrong" (NET_DVR_PASSWORD_ERROR) [1, 2].

    This error occurs when a client software (like iVMS-4200), a web browser, or a third-party application tries to connect to a Hikvision device (NVR, DVR, or IP camera) using incorrect login credentials [2, 3]. Quick Fix Checklist

    Verify Credentials: Double-check the username (usually admin) and the password. Remember that passwords are case-sensitive.

    Check for Account Lockout: If you enter the wrong password too many times (typically 5 attempts), the device may lock your IP address for 30 minutes [4].

    Workaround: Reboot the camera/NVR or wait for the lockout timer to expire before trying again.

    Sync Client Software: If you recently changed the password on the device itself, you must update the "Device Management" settings in your software (e.g., iVMS-4200) to match the new password [3]. Step-by-Step Troubleshooting Guide 1. Test via Web Browser

    Before troubleshooting complex software, try logging into the device directly through its IP address in a browser (Internet Explorer or Chrome with the IE-tab extension is recommended for Hikvision). ⚠️ Only do this in secure local networks,

    If you can log in here but still get Error 23 in your software, the issue is with the software configuration, not the camera itself. 2. Update iVMS-4200 / Management Software If you are using iVMS-4200: Go to Device Management. Select the device showing the error. Click Modify.

    Re-enter the Username and Password manually to ensure no hidden spaces or old saved data are interfering [3]. 3. Check for IP Conflicts or Auto-Login

    Sometimes another background service or an old phone app (Hik-Connect) is trying to log in repeatedly with an old password. This can trigger a constant account lockout, making it seem like your "correct" password isn't working.

    Turn off other apps/services temporarily while you verify the primary connection. 4. Resetting a Forgotten Password

    If you have confirmed that you don't know the password, you have two main options:

    SADP Tool: Download the Hikvision SADP tool on a PC. Select the device and click "Forgot Password." It will generate an XML file or QR code you can send to Hikvision support or your distributor to get a reset key [5].

    Physical Reset: Many IP cameras have a physical reset button. Hold it for 15 seconds while powering the device on to restore factory defaults (this will reset the password to the "inactive" state). Technical Context for Developers

    If you are receiving this error while developing with the HCNetSDK.dll:

    Ensure the NET_DVR_USER_LOGIN_INFO structure is correctly populated before calling NET_DVR_Login_V40.

    Verify that the sPassword field does not exceed the character limit defined in the SDK documentation.

    Do you have the SADP tool installed to check if the device is showing as "Active" or "Locked"?
