Dashcams Explained: What They Do, Where to Install Them and What to Look For | Tynan Motors

Dashcams are becoming an increasingly popular accessory for Australian drivers, offering added peace of mind, security and protection on the road.

Whether you drive a new vehicle or an older model without built-in cameras, this guide explains everything you need to know about dashcams in Australia.

Are Dashcams Legal in Australia?

Yes — dashcams are legal to use in every Australian state and territory, provided they are installed correctly and do not obstruct the driver’s view of the road. While specific regulations vary slightly between jurisdictions, the general rules are consistent nationwide.

Best-practice guidelines recommended by Tynan Motors include:

• Mount the dashcam behind the rear-view mirror so it does not interfere with visibility
• Avoid installing the camera in tinted sections of the windscreen
• Keep the dashcam outside the driver’s direct field of vision
• Use a secure mount or adhesive pad rather than a suction cup
• For smaller vehicles, avoid dashcams larger than 5.5 inches
• NSW drivers should follow Transport for NSW placement guidelines

Correct installation ensures your dashcam footage remains legal and usable if needed.

Where Should a Dashcam Be Mounted?

Proper dashcam placement is critical for safety and compliance.

Recommended mounting positions include:

Behind the Rear-View Mirror

Mounting the dashcam high and centrally behind the rear-view mirror helps keep it discreet while capturing a clear view of the road ahead.

Rear Window (If Using a Rear Camera)

A rear camera should be mounted high in the centre of the rear window, ensuring it does not block the brake light or rear demister.

Check the Viewing Angle

Aim for roughly half road and half sky in the frame to reduce glare and ensure balanced exposure in varying light conditions.

If you’re unsure, the team at Tynan Motors can offer advice on suitable dashcam placement for your specific vehicle.

How Do Dashcams Work?

Most dashcams are designed to be simple and convenient, operating on a “set and forget” basis.

Typical features include:

• Automatic recording when the vehicle starts
• Continuous loop recording that overwrites old footage
• Memory card storage
• Built-in impact sensors that save footage during a collision

When choosing a dashcam, it’s worth considering:

• Power options – 12V socket or professional hardwiring
• Impact detection – footage automatically locked during sudden movement
• Parking mode – monitoring while the vehicle is parked
• Footage access – via screen, mobile app or microSD card

Legal and Privacy Considerations

Dashcam footage can be valuable after an incident, but it’s important to use it responsibly.

Key legal points to be aware of:

• Disable audio recording: Recording conversations inside a vehicle without consent is generally illegal across Australia. In NSW, this breaches the Surveillance Devices Act
• Public vs private spaces: Recording on public roads is legal, but capturing footage inside private property may raise privacy concerns
• Sharing footage: Posting identifiable footage online can result in privacy or defamation complaints
• Providing evidence: Ensure time and date stamps are correct and keep original files unedited

For official reporting, dashcam footage should be submitted through police portals such as NSW Police, Crime Stoppers or Policelink.

What Dashcam Should You Choose?

Choosing the right dashcam depends on how much coverage you want.

• Entry-level dashcams typically record the front view only
• Multi-camera systems offer front, rear and side coverage, which can be useful in busy urban driving or multi-vehicle incidents

Advanced dashcams now offer features such as:

• Ultra-high-definition recording
• Surround-view coverage
• Driver assistance alerts
• Automatic footage transfer to your phone
• Parking surveillance for added security

These systems can complement your vehicle’s existing safety technology, especially if it does not come with built-in surround cameras.
