Guide
A dashcam starts with the vehicle or its power supply, records video in short files and overwrites the oldest ordinary clips when storage fills. Saved events are protected separately, subject to settings and available card space.
The camera receives power from a vehicle socket, USB supply or hardwire kit and normally begins recording automatically. Its image sensor captures the road, a processor compresses the video and the files are written to a memory card.
Instead of stopping when the card fills, the dashcam divides the journey into short clips and overwrites the oldest ordinary recording. Card capacity, video quality and the number of cameras determine how much history remains.
A sudden movement can prompt the camera to mark the current file as an event so routine looping does not immediately replace it. Sensitivity must be set carefully because rough roads can create unwanted protected clips, and even protected storage is finite.
A supported camera can watch for impact, motion or time-lapse events after the ignition is off. It needs an appropriate constant-power source with low-voltage protection, or a compatible external battery system, and its behaviour varies by model.
Depending on the camera, remove the microSD card, connect by local Wi-Fi or use a maker's app. Copy the original incident clip promptly and avoid editing the only copy.
Tesla uses the vehicle's external cameras and supported USB storage for Dashcam clips. Controls and availability differ by vehicle, software and region, so the current Tesla owner's manual is the authority for formatting, saving and viewing footage.
Common questions
On supported vehicles, Tesla records selected exterior-camera views to correctly formatted USB storage. Saving methods and viewing options depend on the vehicle software described in the owner's manual.
They record the road to short looping files, replace older ordinary footage and protect selected event clips when triggered or saved manually.
It normally records while powered. Recording while parked requires a model with parking mode and a suitable power arrangement.
Most standalone models need a compatible card to store video, though some connected products add internal or cloud functions. Follow the exact model specification.
Ordinary loop files are automatically overwritten as storage fills. Event files may be protected, but you should still copy important footage quickly.
Keep exploring
A plug-in installation suits basic driving recording; professional hardwiring is the safer route for neat cabling and parking mode. Keep every camera and cable clear of vision and airbags.
A two-channel system is the clearest choice when you want evidence from both directions. Prioritise rear-camera quality, cable length and an installation that keeps the driver's view clear.
Choose the DR970X Plus for 4K front recording, the DR770X for Full HD dual-channel coverage, or the DR970X Box Plus for a separated recording unit.
Start with the coverage you need: front-only for simplicity, front-rear for broader evidence, or a dedicated motorcycle system. Then decide how you will power it.
