Guide
A dash cam can record after the ignition is switched off only when the camera supports parking mode and has a suitable power source. Battery protection and correct installation are essential.
A dash cam recording when the car is off needs software designed for parked operation. Depending on the model, it may save impact-triggered clips, record after detected movement or use a lower-frame-rate time-lapse mode.
A switched accessory socket normally loses power with the ignition. Common alternatives are a compatible hardwire kit connected to constant and accessory circuits, or a dedicated dash cam battery pack installed to the maker's instructions.
Use low-voltage cut-off and a timer where supported. The safe setting depends on the vehicle, battery condition, climate and camera load; follow the camera and vehicle guidance rather than copying a universal threshold.
Impact-only recording uses less storage and power but may miss events before a trigger. Motion detection captures more activity and more false alerts. Time lapse provides broader continuity without normal-speed detail.
Park in a typical location and review both channels. Reflections, dark glass, a sunshade or a rear demister pattern can affect what is visible, especially at night.
After installation, turn the vehicle off, wait for parking mode to engage and create a safe test event. Confirm the file appears in the expected folder and that the camera exits parking mode after restart.
Common questions
Only if the model supports parking recording and continues to receive suitable power. A camera connected to a switched socket usually turns off with the vehicle.
It consumes power, but a compatible hardwire kit can stop recording at a configured voltage or time. Battery condition and installation still matter.
Potentially, when power capacity, cut-off settings and the selected mode allow it. Actual duration varies, so check the camera after representative overnight use.
Motion detection records more surrounding activity but creates more files. Impact detection is more selective, though it may not preserve the lead-up unless the camera buffers video.
Use only a power solution approved for in-vehicle dash cam operation. Ordinary consumer power banks may not be designed for cabin temperatures, charging behaviour or unattended use.
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.
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.
