Audio via Coaxial Cable: The DVRs support the transmission of audio signals over the same coaxial cable used for video, which simplifies cabling and installation.
High-Definition Output: The units feature both HDMI and VGA outputs, supporting resolutions up to 1920 x 1080 (Full HD) for most models. Some high-end variants can even offer 4K (3840 x 2160) HDMI output.
