The short answer is yes — but it depends on how your dash cam is set up. While driving, all dash cams record continuously. When parked, only cameras with parking mode and a hardwire kit keep recording. Here's exactly how it works.
✅ While driving: yes, all dash cams record continuously via loop recording.
🅿️ While parked: only if your camera has parking mode and is hardwired to your fuse box.
How dash cam recording actually works
Dash cams record in a continuous loop. When your memory card fills up, the camera automatically overwrites the oldest footage to make room for new recordings. You never need to manually delete files — it manages itself.
Most cameras record in 1–3 minute segments. This makes it easy to locate specific footage — if an incident happened at 8:47am, you look for the 8:46 or 8:47 segment. Important footage (triggered by G-sensor impact or manually locked) is saved separately and not overwritten.
The three recording modes explained
1. Continuous recording (while driving)
Runs from the moment you start the engine to when you turn it off. Powered by your cigarette lighter socket or hardwire kit. All dash cams do this. Footage loops automatically — no manual management needed.
2. Parking mode (while parked)
Keeps the camera active after you turn the engine off. Uses motion detection or G-sensor impact to trigger recording — so it only records when something actually happens near or to your car. This is what captures hit-and-runs, vandalism and car park bumps. Requires a hardwire kit — a cigarette lighter socket loses power when you turn the key.
3. Event/emergency recording
Triggered automatically by the G-sensor when it detects a sudden impact or sharp braking. The camera locks that footage so it can't be overwritten by the loop. You can also lock clips manually by pressing the event button. Works during both driving and parking modes.
Does parking mode drain your battery?
This is the most common concern — and it's a valid one. Parking mode does draw from your car's battery while the engine is off. The good news is that quality dash cams and hardwire kits have built-in voltage cut-off protection. When your battery drops to a set threshold (typically 11.6–12V), the camera shuts itself off automatically to make sure you can still start your car.
In practice, for most modern vehicles with a healthy battery, parking mode overnight is not a problem. Where it can become an issue:
- Older vehicles with a weak or ageing battery
- Vehicles parked for multiple days without being driven
- Very hot conditions (Australian summer) which increase battery draw
⚠️ If you're parking for extended periods (airport, long trip), consider setting your hardwire kit to a higher cut-off voltage, or switching parking mode off. Your installer can help you configure this.
Do you need a hardwire kit for parking mode?
Yes. A cigarette lighter socket only has power while the ignition is on — when you turn the car off, the socket goes dead and the camera switches off. To keep the camera running in parking mode, it needs to be wired directly to your fuse box via a hardwire kit, which draws a small trickle of power from your car's battery.
Most VIOFO cameras support parking mode with the addition of a hardwire kit. Our own Extnix dash cam comes with a hardwire kit included in the box:
How much storage do you need for 24/7 recording?
For driving only — most people find 64GB or 128GB plenty. A 4K camera on a 128GB card stores roughly 4–6 hours of driving footage before it loops.
For parking mode as well — go for 128GB minimum, ideally 256GB. Parking mode footage is lower resolution to conserve space, but if you're leaving the car overnight regularly, you want enough buffer that important footage isn't overwritten before you check it.
Top 2026 VIOFO models support up to 1TB microSD. For most everyday drivers 128GB is the sweet spot.
Which dash cams support parking mode?
All VIOFO cameras we stock support parking mode. The difference is whether the hardwire kit is included or purchased separately:
Professional installation for parking mode
Plugging a dash cam into the cigarette lighter takes five minutes. Hardwiring it correctly for parking mode — running cables cleanly through the headlining, setting voltage cut-off, hiding all wiring — is where professional installation makes a real difference.
A properly installed hardwired dash cam has no visible cables in the cabin and protects your car around the clock without any risk to your battery.
