The HCNetSDK.dll9 Error typically occurs when using Hikvision’s HCNetSDK.dll, a software development kit (SDK) library, for integrating Hikvision security cameras. Definitely, Error [9] refers explicitly to “SDK version mismatch,” indicating that the version of the SDK is incompatible with the device’s firmware or software
TROUBLESHOOT HIKVISION CAMERA DISPLAY ERROR DS-2CD2387G2P-LSU/SL in (NVRs, and Software IVMS 4200)
- Solution to Error (Live View Failed) NVR
- Solution to Error (HCNetSDK.dll[9]) IVMS-4200
Figure 1: Error (Live View Failed) Hikvision NVR Display
Figure 2: Error (HCNetSDK.dll9) display IVMS-4200
When adding the DS-2CD2387G2P-LSU/SL camera, an error is displayed directly in the NVR views or the IVMS-4200 software (Figure:1 and 2). In that case, this type of camera requires a unique video configuration. To solve it, you can try the following:
The first thing to try is to enter the camera configuration, modify the Video parameters, and try different settings (Resolution, Stream Type, Video Encoding, Bitrate Type, Max Bitrate, and Frame Rate). Also, if modifying these parameters does not solve the camera display, the following solutions should be tried.
Update camera firmware to the latest version.
Upgrade DVR/NVR firmware to the latest version.
Contact technical support directly with the manufacturer.
No problem after making these options, applying the options of numeral 2 and then numeral 1, the camera could be displayed correctly with the following video settings.
CAUSES OF HCNetSDK.dll9 ERROR
- SDK Version Mismatch:
- The HCNetSDK.dll version does not match the device’s firmware version.
- Outdated Firmware:
- The firmware on the Hikvision security cameras device is not up-to-date.
- Improper SDK Initialization:
- The application has not properly initialized the SDK.
- Configuration Errors:
- Incorrect or missing configuration files related to the SDK.
- Network or Authentication Issues:
- Incorrect login credentials or network communication problems.
iVMS 4200 COMMON ERRORS
Hikvision’s software is a widely used video management tool, but users can encounter common errors during installation, configuration, or daily use. Here’s a guide to understanding and resolving these issues.
DEVICE OFFLINE OR NOT ADDED
Often occurs due to network misconfigurations, incorrect IP address settings, or credential issues. This happens when the device and the computer running IVMS-4200 are on different subnets, the device’s IP address is misconfigured, or a firewall is blocking the connection. Additionally, incorrect login credentials, disabled device features (e.g., platform access), or firmware/software incompatibility can also cause the issue. Ensuring proper network setup, verifying credentials, and maintaining updated firmware can typically resolve this error.
FAILED TO START LIVE VIEW
Is usually an insufficient network bandwidth, mismatched stream settings, or codec incompatibility between the camera and the software. High-resolution streams or bitrates may overwhelm the network or the computer’s processing capabilities. Additionally, outdated device firmware or unsupported video codecs (e.g., H.265) can prevent the software from displaying the feed. Other potential causes include firewall restrictions, a weak network connection, or hardware limitations of the PC running this software. Adjusting the stream parameters, updating firmware, and ensuring proper network configuration can help resolve this issue.
LOGIN TIMED OUT
Network communication problems, incorrect login credentials, or device configuration issues usually cause the “Login Timed Out” error in Hikvision’s software. Common reasons include unstable or interrupted network connections, incorrect IP address or port settings, or the device being powered off or unreachable. Firewalls, antivirus software, or blocked ports can prevent successful login attempts. Additionally, excessive network latency or outdated firmware may lead to timeouts. Ensuring accurate login credentials, verifying the device’s online status, and checking network and firewall settings can typically resolve this issue.
DEVICE ALREADY ADDED
This error occurs when a device has been previously registered to the software, often with duplicate entries in the device list. This can happen if the device is re-added using a different IP address, alias, or network protocol or if it has been linked to another user account on the same platform. Miscommunication between the software and the device due to cached data or overlapping configurations can also trigger this error. Removing duplicate entries, ensuring consistent device details, and avoiding multiple account conflicts can help resolve the issue.
HCNETSDK.DLL9 ERROR
The HCNetSDK.dll[9] Error is a mismatch between the version of the HCNetSDK.dll library and the firmware of the connected Hikvision devices. This occurs when the SDK version used in the application is incompatible with the device’s firmware or when outdated SDK files are used. Additionally, issues such as missing or improperly placed SDK-related files, incorrect initialization of the SDK, or network misconfigurations can contribute to this error. Ensuring the SDK version matches the device firmware, updating all related files, and properly configuring the application can help resolve this issue.
HIGH CPU OR MEMORY USAGE
Typically occurs due to excessive resource demands from high-resolution live streams, multiple simultaneous video streams, or processing-intensive tasks like decoding and playback. Running the software on hardware that does not meet the system requirements or using advanced features, such as AI analytics or large-scale device management, can exacerbate the issue. Inefficient graphics driver settings, outdated software, or a lack of hardware acceleration support may also contribute. Reducing stream resolution, limiting the number of active streams, and upgrading PC hardware or enabling GPU acceleration can help mitigate this problem.
BLACK SCREEN DURING LIVE VIEW
Is an issue with the computer’s graphics settings, incompatible video codecs, or network problems. Outdated or incompatible graphics drivers, insufficient system resources, or software rendering errors can prevent the display of video streams. Additionally, a blank screen may result in network issues, such as poor connectivity or blocked video stream ports. Incorrect stream settings, such as unsupported resolutions or codecs like H.265 without proper decoding support, can also contribute. Updating graphics drivers, verifying stream settings, and ensuring a stable network connection often resolve this issue.
FAILED TO PLAY BACK VIDEO
Is an incorrect playback settings, such as selecting a time range with no recorded footage or attempting to access corrupted or unsupported recordings. Incompatible video formats or outdated firmware on the recording device can also lead to playback issues. Additionally, network instability or insufficient bandwidth may prevent the software from retrieving footage stored on the device. Ensuring proper time range selection, updating firmware, and verifying the integrity of the recorded files can help resolve this issue.
