4 Channel 1080P H.265 Dual 512 GB Vehicle Mobile DVR System — Loop Record, IR Night Vision Waterproof Front/Side Backup Cameras with 7 inch VGA Monitor for RV Truck Bus Camper Van

Storage and recording: Supports two 512 GB SD cards (totaling 1024 GB; SD cards not included). Uses H.265 compression to save roughly 30-40% more space versus H.264, and automatically overwrites the oldest files to maintain continuous loop recording. Cameras: Includes four 1080P AHD 2.0MP metal cameras, each with a 3.6MM lens. All four exterior cameras feature IR night vision and are waterproof for reliable outdoor use in adverse weather. Also provided is an indoor mini dome camera (not waterproof and without IR) that contains a built-in microphone, making it suitable for mounting behind the windshield for audio capture. Monitor and installation: Comes with a 7-inch HD VGA monitor (1024x600 resolution). The monitor bundle includes 8-foot power supply cables to allow flexible mounting locations and can be powered directly from the MDVR to simplify wiring. Power protection and event handling: The MDVR uses a super-capacitor for dependable recording during shocks and heavy vibrations. It supports 5-second pre-recording and mandatory event video saving to ensure critical moments are retained. Parking and alarms: Configurable delay recording (24H Parking Monitor) lets the system continue recording after the vehicle is switched off, with automatic shutdown after up to 24 hours (powered by the vehicle's battery). The backup alarm displays parking grid lines to aid parking; when an alarm triggers, the monitor switches from a quad view to a single enlarged camera view. Convenience: An IR extender is included so you can hide the MDVR (for example, behind the dash) yet still operate it with the remote without pointing directly at the unit, keeping the cockpit neat and uncluttered.
