VIOFO A329S Series: 20 Questions Answered

The VIOFO A329S series has caused quite a stir, and we know you’ve got questions before deciding whether one is right for you. So we’ve rounded up the 20 we hear most.

Models and line-up

What’s improved on the A329S series compared with the A329?

The A329S series supports three-channel recording and offers optional modules, including an infrared fisheye cabin camera, a telephoto camera and a waterproof camera. It also adds a new parking mode, Low Power Impact Detection, and a video multiplexing feature.

What combinations are available?

There are three versions:

• Standard: A329S 1CH, A329S 2CH, A329S 2CH IR and A329S 3CH
• Telephoto: A329T 2CH, A329T 3CH and A329TW 3CH
• Waterproof: A329SW 2CH, A329SW 3CH and A329WW 3CH

Is there a version that suits lorries and other large vehicles?

Yes. We recommend the A329WW 3CH. It comes with two waterproof rear cameras and a choice of cable lengths. The cameras can go under the wing mirrors, at the rear or wherever suits you, which makes it ideal for HGVs and other large vehicles.

What’s the difference between the main units of the A329S, A329T and A329SW?

The main difference is the firmware. Each model runs firmware optimised for its configuration and features.

What’s been upgraded on the A329S cabin camera?

It’s now 2K for clearer in-cabin footage, with a 210° ultra-wide lens that captures both the interior and outside, reducing blind spots.

Accessories and compatibility

Can I use the A329 GPS module on the A329S?

Yes. The GPS module works with both the A329 and A329S.

What’s the largest microSD card supported?

The A329S supports microSD cards up to 512GB. We recommend VIOFO’s own cards.

How can I use a portable SSD and power at the same time?

The portable SSD plugs into the Type-C port on the side of the main unit, while power comes through the Type-C port on the GPS mount, so you can use both together without interference.

Can I use the A229 Pro waterproof rear camera with the A329S?

No. The A229 Pro waterproof rear camera isn’t compatible with the A329S.

Can I buy a front and rear A329S and add the telephoto camera later?

Yes. You just need to update the firmware to the A329T version.

Can I use my A229 Pro rear camera cable if I upgrade to the A329S?

No. The A229 Pro rear cable isn’t compatible. You need the original A329S rear cable.

Which CPL suits the fisheye and waterproof cameras?

Neither needs one. CPL filters aren’t required for the fisheye camera or the waterproof camera.

Parking mode and hardwire kits

How do I turn on parking mode?

Use the HK4 or HK6 hardwire kit to enable automatic parking mode, which supports Low Power Impact Detection, Hybrid Parking Recording, Time-lapse, Low Bitrate and Auto Event Detection. For the Cut-off Voltage function, you’ll need the HK6.

What’s the difference between the HK4 and HK6 on the A329S?

Both offer low voltage protection. The HK6 can also send your vehicle’s voltage data to the dash cam.

Do the camera’s Cut-off Voltage and the HK6’s Low Voltage Protection switch conflict?

No. They work one after the other:

• When your battery voltage drops to the Cut-off Voltage you’ve set in the camera’s Hybrid Parking Recording settings, the camera switches from normal parking mode (Time-lapse, Low Bitrate or Event Detection) to Low Power Impact Detection.
• If the voltage keeps falling and reaches the Low Voltage Protection level set on the HK6’s physical switch, the hardwire kit cuts power completely and the camera shuts down.

For best results, set the camera’s Cut-off Voltage slightly higher than the hardwire kit’s Low Voltage Protection value.

How does Low Power Impact Detection work?

The camera stays in low-power standby. When it detects an impact, it starts recording within two seconds for one minute. If it detects movement during that time, recording is extended for up to three minutes.

Everyday use

Why are some videos deleted automatically?

Loop recording overwrites the oldest files automatically. Locked and event videos are protected and won’t be overwritten.

Can the dash cam connect to my phone automatically?

No, the dash cams don’t connect to phones over Wi-Fi automatically. You can set your phone to remember the network, then once the dash cam’s Wi-Fi is on, tap to connect.

Is there one firmware for every A329S camera combination?

Not at the moment. VIOFO publishes four firmware files: one for the A329S (shared with the A329SW), one for the A329T (shared with the A329TW), one for the A329TC and one for the A329WW.

Does the camera cope with high temperatures?

VIOFO dash cams go through rigorous high-temperature testing and are designed to run safely between -20°C and 65°C. A built-in temperature sensor monitors the internal temperature, and if it gets too hot, the dash cam shuts down automatically to protect itself.
