The NVR-420 provides a user-friendly management interface enabling users to remotely operate the NVR, view live monitoring videos and play back the recorded videos via a web browser in the computer or any mobile devices.

The NVR system is also expandable for multi-site management with the bundled CMS software. For instance, the CMS software in the NVR-420 can manage up to 64 units of NVRs at the same time; that means, there potentially would be 256 channels of IP cameras being viewed simultaneously. With multi-monitor and E-Map functions, the NVR-420 helps the administrators to monitor the surveillance system more efficiently and effectively.

The NVR-420 supports an HDMI interface allowing users to connect directly to an HDMI capable HDTV / monitor. It then can be operated with the bundled remote control and mouse. The NVR-420 is compatible with most major camera brands in the market and can automatically search and find the available cameras on the network, which greatly reduce the user effort when configuring the system.
