Q: Will this new firmware work on the DH-XVR1B16H with an older hardware revision (Rev 1.0)? A: Yes, the firmware is backward compatible with Rev 1.0, 1.1, and 2.0 boards. However, Rev 1.0 lacks AI SMD 2.0 support due to chipset limitations.
Q: Can I downgrade to an older firmware if I dislike the changes? A: Technically no. Dahua’s bootloader prevents downgrading to versions older than V4.002 without a special recovery tool. Always test in a non-critical environment first. dhxvr1b16h firmware new
Q: My DVR came from a white-label brand (e.g., Amcrest, Lorex). Can I use this firmware? A: No. White-label devices have modified hardware IDs. Installing Dahua firmware will likely brick them. Only use firmware from your original brand. Q: Will this new firmware work on the
Q: Does the new firmware support H.265+? A: No. The DH-XVR1B16H chipset is limited to standard H.265 (Main Profile). It cannot support H.265+ (which requires a different encoder). Q: Can I downgrade to an older firmware
Cause: Browser cache or new security enforcement (HTTPS only).
Solution: Clear cache. Access via https://[DVR-IP]:443 instead of HTTP. Install the latest WebPlugin.exe from the DVR’s login page.
Earlier firmware had a bug where ONVIF Profile T (standardized H.265) would stutter every 10 seconds. The new version fully implements Profile T conformance, allowing seamless integration with third-party VMS like Blue Iris or Synology Surveillance Station.
The built-in web server (port 80/443) no longer relies on outdated NPAPI plugins. The new interface uses HTML5 WebSocket, meaning you can view live video on Chrome, Edge, or Firefox without installing any proprietary plugins.
