Viofo A329S 3CH Dash Cam BP100 Battery Pack EP100 Expansion Battery 512GB Bundle

This VIOFO A329S 3CH bundle combines the three-channel dash cam recording 4K at the front, 2K at the rear and 2K from a 210° infrared fisheye cabin camera, all using Sony STARVIS 2 sensors with HDR, with a BP100 battery pack, an EP100 expansion battery and a 512GB microSD card.

The BP100 battery pack powers parking mode from its own 7650mAh LiFePO4 battery, so the car battery is never drained. The EP100 expansion battery clips onto the BP100 and doubles the stored energy for much longer parking mode sessions. The 512GB Viofo high-endurance card is ready to record out of the box. The dash cam, BP100 battery pack, EP100 expansion battery and VIOFO 512GB microSD card are also sold separately.

A329S 3CH Dash Cam Bundle

A329S 3CH dash cam

Powered by a Quad Core ARM Cortex A53 chipset and Sony STARVIS 2 sensors, the A329S records true 4K and 2K footage, capturing number plates and fine detail clearly day and night.

IMX678 & IMX675 sensors — less noise, less motion blur

The front camera uses the Sony STARVIS 2 IMX678 1/1.8" 8MP sensor, delivering greater clarity, reduced low-light noise and less motion blur. The rear and cabin cameras use Sony STARVIS 2 IMX675 1/2.8" 5MP sensors, which offer a 2.5× wider dynamic range than a STARVIS pixel of the same size.

3-channel HDR — clear number plates

Sony STARVIS 2 technology combined with HDR balances bright and dark areas across all three channels, capturing accurate number plates even in fast motion.

4K recording — clarity and detail

The A329S front camera delivers sharp, detailed 4K footage day and night.

Upgraded 2K HDR video with 210° FOV — cabin coverage with enhanced clarity

Powered by the Sony STARVIS 2 IMX675 sensor, the A329S fisheye cabin camera is Viofo's first cabin camera to record in 2K. Four infrared LEDs preserve detail in low light. The 210° fisheye lens covers the full cabin interior and sides, reducing blind spots — suitable for family cars and ride-share use alike.

Wi-Fi 6 connectivity

Wi-Fi 6 triples transfer speeds on the 5GHz band. A one-minute 4K clip transfers to your phone in under 10 seconds.

Smart voice control

Spoken commands start a recording, take a photo, or toggle Wi-Fi on and off in multiple languages. The A329S also announces setting changes and memory card errors aloud.

Accurate GPS tracking

The built-in GPS locks onto four satellite systems: GPS, BeiDou, Galileo and GLONASS. Footage played back in the Viofo app or PC player displays location, speed and time.

Upgraded USB 3.0 port — fast video downloads

Connect the A329S directly to your phone via USB 3.0 and transfer files at up to 55MB/s (tested on iPhone 15 Pro Max). The same connection handles firmware updates — no card reader needed.

Multiplex video — instant sharing

Record any combination of camera views. The A329S gives full control over how footage from one or multiple angles is presented, with no editing required.

Up to 4TB SSD

Connect a portable SSD of up to 4TB for extended recording capacity. The A329S automatically backs up footage from the microSD card to the SSD, reducing card wear and preserving important clips on a larger drive.

BP100 Battery Pack for Parking Mode

The Viofo BP100 is a 12.8V 7650mAh (98Wh) LiFePO4 battery pack that powers the dash cam in parking mode for up to around 32 hours on a single-channel camera, without touching the car battery. It recharges in about 70 minutes when hardwired or around 100 minutes from the cigarette lighter, and its Bluetooth link to the Viofo app shows charge level and temperature alerts. Hardwiring cables are included, so no separate hardwire kit is needed.

EP100 Expansion Battery

The EP100 connects to the BP100 to add another 7650mAh of LiFePO4 capacity, roughly doubling parking mode runtime. It suits taxis, fleet vehicles and anyone who leaves the car parked for days at a time.
