Applies to: All Reolink NVRs.
HDMI port is a proprietary audio/video interface for transmitting high-quality and high-bandwidth streams of audio and video between devices.
VGA port utilizes analog signals, which means it is only capable of lower resolutions and lower quality displays on screens. It does not transmit audio signals.
Reolink NVR can either use an HDMI or VGA cable to connect to the monitor.
