Capture and retain surveillance video across up to 8 camera channels at 2 MP with a single-HDD XVR architecture. UNITED DIGITAL XVR301-08G3 provides the recorder-side capacity profile for smaller physical-security systems that need an eight-channel recording point. Its 2 MP rating aligns the recorder with 1080p-class camera deployments, while the one-HDD design concentrates local storage in a single drive position. Use this recorder where the planned camera count does not exceed 8 channels and local recording is required at the installation. The channel limit is a central selection point for a surveillance recorder: each camera assigned to the system consumes one available channel. An eight-channel platform suits compact sites such as small offices, retail spaces, entrances, reception areas, and limited-perimeter camera layouts. The defining capacity combination is 8 channels, 2 MP recording, and support for one HDD. That makes it a focused option within an XVR range for installations that do not need higher channel counts or multiple-drive storage architecture. Storage duration depends on the installed drive capacity and recording configuration, so retention planning should account for the number of active channels and the required recording period.
