You will be required to update your DVR or NVR to the latest available firmware upon system start-up. This is required to enable remote viewing of your system (you will also need to upgrade your client software or mobile apps). When notified after start-up, you will be prompted to upgrade the firmware. Click OK, and enter your system user name (default: admin) and password (default: 000000). The system will then restart once the upgrade has been installed. After this initial set-up, firmware upgrades will automatically be installed as long as your DVR or NVR is connected to the internet.
