What Is an IR Dash Cam? A Beginner's Guide

Worried that your dash cam cannot see what happens inside your car once the sun goes down? That is exactly the problem an IR dash cam is built to solve. If you drive for Uber or DiDi, run a family taxi service, or just want to know what is going on in the cabin at night, an IR dash cam records a clear picture in the dark, without a bright light shining in anyone's face. This guide explains what an IR dash cam is, how it works in plain English, and how to choose the right one.

We are Michael and Harrison from The Dash Cam Guys, an Australian dash cam specialist. We fit and explain these cameras every day, so this is written the way we would talk you through it over a coffee. No jargon left hanging.

First, what does IR actually mean?

IR is short for infrared. Infrared is simply a type of light that our eyes cannot see. When you think of light, you picture sunshine or a lamp, but that visible light is only a small slice of all the light around us. Infrared sits just beyond the red end of what we can see, which is where the name comes from.

Here is the everyday version. Your TV remote uses infrared to talk to your telly. You cannot see the beam, but the TV can. An IR dash cam works on the same idea. It sends out infrared light that you cannot see, and its camera is built to see that light, so it can film a clear picture in what looks to you like total darkness.

So what is an IR dash cam?

An IR dash cam is a dash cam with a camera that films the inside of your car and uses infrared to see in the dark. Most of these are two or three camera systems. There is the usual front camera watching the road, and then an interior camera, often called a cabin camera, that points back at the seats.

Only the interior camera uses infrared. If you look closely at it, you will see a ring of tiny lights around the lens. Those are infrared LEDs, small bulbs that give off infrared light. They are what let the cabin camera record faces and movement clearly at night, even with your interior lights switched off. Because the light is invisible, it does not dazzle you or your passengers while you drive.

Pro Tip: A normal dash cam and an IR dash cam both film the road ahead just fine. The difference is the inside of the car at night. If recording the cabin in the dark matters to you, that is the one job only an IR dash cam does well.

Why would I want an IR dash cam?

For most private drivers, a front camera is plenty. An IR dash cam earns its keep the moment you need to record what happens inside the car, especially after dark. Here is who benefits most.

Rideshare drivers. If you drive for Uber or DiDi, an IR dash cam gives you an honest record of every trip. Most rides that go wrong happen at night, and a cabin camera captures what was said and done. That is real proof if a passenger makes a false claim or a fare turns nasty.

Taxi and hire-car drivers. The same protection applies. A clear interior recording settles disputes quickly and keeps everyone honest.

Families and learner drivers. Some parents like keeping an eye on how the car is being driven when a P-plater borrows it. A cabin view adds context to what the road cameras show.

Small fleets. If you run a couple of work vehicles, an interior camera helps you understand what happened in an incident, not just what the front camera saw.

How do the infrared LEDs work?

The infrared LEDs sit around the cabin lens and quietly light up the inside of your car with invisible light. The camera sensor is tuned to pick up that light and turn it into a clear video you can watch back.

On the better cameras, the IR LEDs switch on and off automatically. In daylight they stay off, so your footage keeps its natural colour. Once it gets dark, they switch on so the cabin stays visible. Cheaper models sometimes leave the LEDs on all the time, which can wash out the colour during the day, so automatic control is worth having.

One thing to expect: infrared footage is usually black and white, not colour. That is normal. Infrared light does not carry colour the way daylight does, so a night-time cabin clip will look like clear greyscale. It is still perfectly clear for identifying faces and movement.

Can I point the IR camera out the windscreen instead?

You could, but we would not recommend it, and here is the simple reason. If an infrared camera faces out through the windscreen, its own invisible light bounces straight back off the glass. That reflection blinds the camera and leaves your footage washed out and overexposed. Infrared is made to light up a small space like a cabin, not the open road.

So the rule of thumb is easy. Use the front camera to watch the road, and let the infrared cabin camera do what it does best, which is see clearly inside the car at night.

IR night vision or Super Night Vision: what is the difference?

This trips up a lot of first-timers, so let us clear it up. Some dash cams advertise Super Night Vision or a similar name. That is clever software plus a sensitive sensor that brightens a dim scene. It is excellent for the road at night, but it still needs a little light to work with, such as street lights or oncoming headlights.

True infrared is different. It makes its own invisible light, so it can film in complete darkness, like a closed garage with no lighting at all. The catch is that infrared only reaches a short distance, which is why it suits the cabin rather than the road.

In short: Super Night Vision is the go-to for the road in low light, and infrared is the go-to for the cabin in pitch darkness. Many IR dash cams give you both, one on the front camera and one on the interior camera.

Which IR dash cam should a beginner buy?

To take the guesswork out of it, here are three IR dash cams we happily recommend. Each one is genuine Australian stock, backed by our local support, not grey import gear of unknown quality.

Best value all-rounder: WOLFBOX G900 TriPro

The WOLFBOX G900 TriPro replaces your rear-view mirror with a 12 inch touchscreen and records three angles at once: 4K front, 2.5K rear, and a 1080p infrared cabin camera. For nervous first-timers it is a comfortable choice, because it looks like a normal mirror and the screen works like your phone. It even includes a 256GB high-endurance memory card in the box, so you are ready to go. Browse the full WOLFBOX range to compare.

Sharpest cabin detail: VIOFO A329S IR

If image quality is your priority, the VIOFO A329S 2-CH IR pairs a crisp 4K front camera with a 2K HDR infrared cabin lens and a wide 210 degree view of the seats. It uses the excellent Sony STARVIS 2 sensor, which is the part inside that captures the picture and performs very well in low light. Fast Wi-Fi means you can pull a clip onto your phone in seconds. See more in our VIOFO range. If you also want a rear camera, the A329S three-channel version adds one alongside the interior camera.

Full 360 degree coverage: Vantrue E360 ACE

The Vantrue E360 ACE takes a different approach, capturing a full 360 degree view around and inside the car, with eight infrared LEDs keeping the cabin clear at night. It comes with a rear camera too, so you get front, sides, cabin, and rear in one kit. It is a great fit for rideshare drivers who want to leave no gaps. Compare it in the VANTRUE range.

A quick word on setup

All of these cameras can simply plug into your car's 12V socket to get started, the same socket you might use to charge your phone. To unlock parking mode, which keeps the camera watching while you are away from the car, you connect it to your fuse box with a hardwire kit. That is a small job most people have an auto electrician do in under an hour, and we can point you to a trusted local installer if you would rather not tackle the hard yakka yourself.

Still not sure? Just ask us

Choosing your first IR dash cam is easier than it looks once you know the interior camera is the part doing the clever infrared work. Match the camera to how you drive, drop in a high-endurance card, and you are protected inside and out.
