Before beginning the Smart PSS PC NVR setup, ensure you have the following:
| Problem | Likely Cause | Solution |
| :--- | :--- | :--- |
| "PC-NVR Service not running" | Antivirus blocked it | Add C:\Program Files\SmartPSS to AV exception list |
| No video from camera | ONVIF user not created | Log into camera web UI, create a user with "admin" role |
| Recording stops after 4GB | FAT32 file limit | Format HDD as NTFS (not FAT32/exFAT) |
| High CPU usage (100%) | Software decoding, too many cameras | Enable Hardware Decode (NVIDIA CUDA or Intel QuickSync) |
| Playback is choppy | Disk fragmentation | Defrag surveillance drive weekly (or use SSDs for write cache) |
| Cannot add more than 32 cameras | Smart PSS Free limit | Consider upgrading to Dahua DSS Express (paid) |
Even with a perfect setup, issues arise. Deep knowledge of Smart PSS diagnostics separates professionals from amateurs:
A PC NVR is useless if you can’t check it from your phone.
Ironically, while surveillance is about security, a PC running Smart PSS is a high-value attack vector. Default settings are dangerously permissive.
Now you decide when and why to record.
Example configuration for retail store:
Click Copy to apply the same schedule to all cameras.
Click Save.
