Parking mode keeps your dash cam watching after you've switched off — useful for car-park dings and hit-and-runs. But it works differently on every camera, and almost all of them need a constant power supply. Here's how the main types work and how to stop it flattening your battery.

The main types of parking mode
- Motion or event detection (buffered): the camera keeps a short buffer so it saves the moments before and after something moves or bumps the car. VIOFO, for example, saves from 15 seconds before to 30 seconds after an event.
- Time-lapse: records continuously at a very low frame rate (VIOFO offers 1–10fps; Thinkware uses 2fps) so hours of parking fit in small files. VIOFO describes it as the most stable, lowest-power option.
- Low bitrate: records continuously in smaller files, usually with little visible quality loss.
- Impact-only / energy saving: the camera sleeps and wakes only on a knock. Thinkware says its energy-saving mode can extend coverage up to three times.
- Radar: some Thinkware models use low-power radar to spot movement and wake the camera.
- G-sensor parking (Nextbase Intelligent Parking Mode): records when the parked car is bumped and saves a protected file.
Why most need a hardwire or OBD kit
A 12V socket usually switches off with the engine, so parking mode needs a constant supply. That normally means a hardwire kit connected to your fuse box, or a plug-in OBD cable. Thinkware and BlackVue both state their parking modes need hardwiring (or an OBD cable), and Nextbase recommends its hardwire kit over the lighter-socket cable.
A typical 3-wire kit has a constant (battery) wire, an ignition (ACC) wire that tells the camera when you've switched off, and a ground wire to bare metal. Manufacturers recommend a qualified installer if you're not confident at the fuse box.
Protecting your car battery
Good kits cut power before your battery gets too low to start the car. Nextbase's hardwire kit stops at 11.2V. BlackVue lets you set 11.8–12.5V on 12V cars (22.8–24.0V on 24V vehicles), suggests 12.0V as a safe starting point, and recommends 12.2–12.5V in winter on its X-series cameras. You can usually add a timer too — whichever limit is reached first switches the camera off.
Expect hours, not days: BlackVue's Australian guide gives roughly 0–6 hours of parked coverage in motion or time-lapse modes before cut-off, depending on your battery. For longer coverage, some owners add a separate dash cam battery pack.
