5. System Setup 5 5. System Setup In this chap, it will show you how to set the system configuration for your NVR. 5.1 System Configurations The “System Configurations” page provides users options to setup the device quickly and properly. After properly configuring all settings in all the sub-pages, users should expect a fully working network video recorder that is ready to manage cameras on the network. We will start by configuring its network settings to make sure it works correctly in your network.
5. System Setup You need to adjust settings in this page for the device to work properly in your network. It is critical that settings here are configured correctly based on your network environment so that the NVR can be administered through the local area network and cameras can be connected with it. By default, the NVR is set to obtain its IP address from DHCP server, and most likely you should use a static IP address for your management purpose.
5. System Setup static IP address if there is no DHCP server currently presented in the network. Its DHCP server function is also turned on at the same time to assign IP addresses to cameras that are later connected to the network. You can manually turn off the DHCP server function if you wish to use a separate DHCP server. Note: Change the NVR’s IP address would require the NVR to restart. Restart the device under “system Options” “Maintenance” for the settings to take effect. 5.1.
5. System Setup 5.1.3 User Account The NVR can be accessed by multiple users simultaneously. You can add, remove, and edit users by using options provided in this page to keep user information organized. Each NVR comes with a built-in “admin” account with password “airlive”.
