Dash Cameras

Dash Cam Buying Guide

Dash cams, also referred to as drive recorders, DVRs, or dash cameras, are purchased by drivers for two primary reasons: resolving insurance disputes and capturing road incidents, whether for personal use or social media fame. While some UK insurance companies offer discounts for vehicles with dash cams, Australian insurers have not widely adopted this practice. However, the value of dash cams lies in their ability to provide crucial evidence in case of an accident or legal issue.

Every week, insurance providers receive video footage from dash cams, which have led to positive outcomes for their owners. Dash cams protect against dishonest individuals attempting to deceive insurers, ensuring you have solid proof to defend yourself.

Choosing the right dash cam involves balancing your budget with the quality and features of the camera. Dash cams range from affordable models starting around $50 to high-end models exceeding $750. The more expensive dash cams generally offer superior build quality, enhanced features (like GPS, Wi-Fi, time-lapse, night vision), and higher-quality hardware that delivers better footage.

We all encounter reckless drivers on the road, and with a dash cam, you can capture every incident. Just remember, it also records your driving habits, so be mindful of that!

Image Quality of Dash Cams

When it comes to dash cam image quality, there are four main factors to consider: frame rate, resolution, CMOS sensor quality, and lens quality.

• Frame Rate: This refers to how many frames per second (fps) the camera can capture. A higher frame rate results in smoother footage, making it easier to read important details like number plates and road signs.
• Resolution: Most dash cams record in HD (720p) or Full HD (1080p), but the quality can vary depending on the CMOS sensor and lens. Higher-end dash cams typically offer better sensors and lenses, which improve image quality, especially in low-light conditions.
• CMOS Sensor: The CMOS sensor converts light into electronic data. A better-quality sensor can capture more details, particularly in challenging lighting situations like night driving.
• Lens: The lens collects the light. Even if two dash cams have the same resolution, a camera with a better lens and sensor will produce superior footage, especially in low-light conditions.

It’s worth noting that resolution alone isn't the best indicator of image quality. When comparing dash cams, review footage from the camera in real-world conditions, particularly low-light scenarios. For a better comparison, check the manufacturer's website or trusted online reviews rather than relying on YouTube footage, which can be compressed.

Dash Cam Installation

Contrary to the name, most dash cams aren’t installed on the dashboard. Instead, they are typically mounted on the windshield behind the rear-view mirror using adhesive brackets.

For temporary installations, drivers may plug the camera into a cigarette lighter or power socket, but this can obstruct the view or create a potential hazard. For a cleaner, more permanent setup, many choose to hardwire their dash cam. Hardwiring allows the dash cam to keep recording even when the vehicle is off, which is ideal for monitoring the car while parked. Professional installation usually costs around $150, though some users with the right skills can install it themselves.

If you opt for a dual-camera setup with both front and rear-facing cameras, the installation method will depend on your vehicle. For hatchbacks or wagons, you may mount the rear camera on the top of the rear windshield. For other vehicles like cars, vans, and trucks, it’s common to mount the rear camera on the rear license plate frame.

Recording & Memory Cards for Dash Cams

Dash cams generate large amounts of data, so it’s important to use high-speed SD cards to prevent recording errors. Using a regular SD card may cause corruption and even malfunction. For optimal performance, ensure you're using a high-quality, high-speed SD card.

Dash cams typically record footage in a loop, overwriting the oldest video once the SD card is full. Below is an estimated recording time based on the SD card capacity:

Dash Cam Features to Consider

Modern dash cams come with various features that enhance their functionality. Here are some of the most popular options:

• GPS: Many dash cams have built-in GPS to track speed and location, which can be useful for verifying your location during an incident or disputing speeding fines.
• Audio Recording: Some dash cams record audio from inside the car, which can be turned on or off depending on your preference.
• Driver Assistance: Features like speed camera warnings or GPS navigation are available in some models, which can be helpful for safer driving.
• LCD Screens: Some dash cams come with an LCD screen for easier navigation, footage review, and camera adjustments.
• Wi-Fi Connectivity: High-end dash cams often feature Wi-Fi, allowing you to download footage, adjust settings, and view live data remotely.
• Cloud Storage: Some dash cams can upload footage to cloud storage if connected to the internet, providing an additional layer of security.

Understanding Dash Cam Terminology

• 1CH vs. 2CH vs. 3CH: "1CH" refers to a single camera setup (typically front-facing), while "2CH" refers to dual cameras (front and rear). "3CH" refers to three camera setup (Front, rear and cabin). "3CH" are a popular choice for rideshare service vehicles e.g. Uber, Didi, Lyft, and Taxis, etc. 
• Park Mode: This mode allows your dash cam to continue recording while the vehicle is parked. Some dash cams use motion detection, while others record until the car's battery reaches a certain voltage.
• Night Vision Mode: Dash cams with night vision enhance recording in low-light conditions, ensuring clearer footage when driving at night or when parked.
• Infrared Technology: Infrared (IR) lights help improve recording quality in dark conditions, often used in rear-facing cameras to monitor the interior of the vehicle.
• Truck Cams: These are dash cams specifically designed for trucks, often mounted externally to provide a better view of the road behind.
• Polarizing Lenses: Some dash cams feature polarizing lenses, which reduce glare and improve visibility when driving through varying lighting conditions.

Conclusion

Investing in a dash cam can be a wise decision for any driver. Whether you're looking to protect yourself in the event of an accident or simply capture interesting moments on the road, a quality dash cam can provide invaluable evidence and peace of mind. Take your time to choose the right camera based on features, image quality, and installation needs, and you’ll enjoy the benefits of enhanced security while on the road.
