Additional Tips
The error "Failed to start playback. NETSDK returns error" in SmartPSS typically indicates a communication breakdown between the software and the storage device (NVR/DVR or SD card), often due to corrupted background processes, outdated system files, or resource conflicts. Common Fixes
Force Restart via Task Manager: If the software becomes unresponsive or throws this error, open Task Manager (Ctrl+Alt+Delete), locate Smart PSS under the Processes tab, and select End Task. Restarting the application often clears temporary session locks.
Update the SDK Library: Some versions of SmartPSS (notably v2.002) have a known bug with the dhnetsdk.dll file that causes playback to fail even when the timeline shows recorded footage. You can fix this by downloading a newer version of the dhnetsdk.dll file and replacing it in the installation folder (usually C:\Program Files\Smart Professional Surveillance System\SmartPSS).
Format Storage Media: If live view works but playback fails with a NetSDK error, the storage card or hard drive may have file system errors. Users have reported immediate resolution after reformatting the SD card or checking the NVR's HDD status.
Check User Permissions: Ensure the account logged into SmartPSS has the necessary Playback rights. You can verify this by logging in with an administrator account on the NVR and checking the Accounts menu to edit specific profile permissions. Technical Troubleshooting
Firewall/Antivirus Conflicts: Security software like ESET has been known to block traffic between the NVR and SmartPSS, particularly after OS upgrades like Windows 11. Try temporarily disabling your firewall to see if playback resumes.
Network Stability: While live view may work, playback requires more stable bandwidth to pull archival data. If using a spotty connection or a hotspot, the NetSDK may timeout and return an error.
Time Synchronization: Differences between the camera time and NVR time can cause playback to fail or skip. Ensure NTP is enabled on the NVR to synchronize time across all connected cameras. Pro Tip: After reboot, immediately disable "Auto Logout
