Parking Mode: 24/7 Peace of Mind

*Note: To use parking mode, a VIOFO HK6-F hardwire kit is required and sold separately.

Hybrid Parking Recording

Capture More, Consume Less

Hybrid parking starts in time-lapse, low-bitrate or event-detection recording, then switches to impact detection once your set cut-off time or battery voltage is reached.

*Cut-off voltage is only available with the VIOFO HK6-F hardwire kit.

Low Power Impact Detection

Ultra-Low Draw, Instant Guard

Very low power draw makes this mode ideal for long parking sessions. The T340 waits in standby with impact detection always on, waking within 2 seconds to record a one-minute clip.

Standard Parking Mode

Time Lapse Recording

Capture footage without audio at optional frame rates of 1 / 2 / 3 / 5 / 10 fps to conserve storage space and power. With Super Night Vision, the time-lapse footage is brighter and clearer, even in near-total darkness.

Super Night Vision (SNV)

Super Night Vision brightens parking footage in near-total darkness, keeping plates and surroundings visible.

Low Bitrate Recording

Records continuously at a reduced bitrate to extend recording time and save storage while parked.

Auto Event Detection

Detects motion and impacts around your parked car, automatically saving the moments before and after each event.

Smart Geofencing Control

Set Zones, Save Power

Define trusted locations — your home garage or workplace — and the T340 shuts down there instead of entering parking mode. Enable Low Power Impact Recording to keep impact detection on inside those zones.

Low Voltage Cutoff

If voltage ever drops below the level set on the hardwire kit's cutoff switch, power is cut entirely to protect the battery.

Detachable Design

With removable input and output cables and simple plug-in connections, installation, maintenance, and future upgrades are easier than ever.

Voltage Display via Bluetooth

Check your car battery's real-time voltage in the VIOFO Dashcam App via Bluetooth, anytime.

Battery Pack Ready

Longer Parking, Zero Battery Drain

Pair with the VIOFO BP100 or BP60 battery pack (sold separately) and parking mode runs on the battery pack’s own power — for hours longer, with your vehicle battery untouched.
Smart Bluetooth features keep the battery level in view: in the app and on the footage itself.

Cut-off Battery Pack Capacity

Connected to the battery pack, the dash cam reads its level wirelessly and ends parking recording at the reserve you choose (5% / 8% / 10% / 15%). The reserve keeps impact detection armed, so the camera can still wake and record if the car is hit.

Battery Level in the VIOFO Dashcam App

Check the battery pack level on the app home screen — even while the dash cam is off. The dashboard adds charging status, temperature, input and output readings, and the estimated remaining runtime.

Battery Level Stamp on Footage

Enable the Battery Pack Capacity stamp and every clip records the remaining battery level at the moment of recording — useful context when reviewing a parking incident days later.

Instant Footage Lock

Press It, Protect It

One touch is all it takes. Alongside automatic G-sensor impact locking, the side button lets you instantly secure key moments whenever you want. Footage of road incidents, hit-and-runs, or close calls won't be overwritten easily.

Installation Essentials

Everything for a Clean Install

Tamper-Resistant Cover

Cleaner Installation, Better Protection

Protect your dash cam from unauthorized access. The tamper-resistant cover prevents unauthorized tampering or accidental disconnections while maintaining a clean, professional install.
