The NR9581-v2 supports up to two SATA hard drives, each with a maximum capacity of 16 TB, for a total of 32 TB of storage.
How can I access the NVR remotely?
You can access the NVR remotely via the Vivotek VAST software or through a web browser by enabling DDNS and port forwarding on your router. Also, use the Vivotek mobile app for smartphones.
What video compression formats are supported?
The NVR supports H.265, H.264, and MJPEG. H.265 provides better compression efficiency, saving bandwidth and storage space.
How do I perform a factory reset on the NR9581-v2?
Press and hold the Reset button on the rear panel for about 10 seconds until the system reboots. This restores default settings, but user data (recordings) remains unchanged on the HDD.

How do I update the firmware?
Download the latest firmware from the Vivotek support website. Go to the NVR's web interface under System > Maintenance, upload the firmware file, and follow the prompts. Do not power off during update.
Why is my NVR not detecting cameras?
Ensure cameras are powered and connected to the same network subnet. Check that DHCP is enabled or assign a static IP. Verify camera compatibility and ONVIF support. Restart both camera and NVR.
What is the default login username and password?
The default credentials are admin for both username and password, with an empty password field. It is strongly recommended to change these upon first login for security.
