Why You Need a Dash Cam in Your Vehicle

In today’s driving landscape, especially in the UK where nearly 31% of vehicles are equipped with dash cams, these devices have become an essential tool for many drivers. A dash cam, or dashboard camera, offers a multitude of benefits, from providing crucial evidence in the event of an accident to deterring bad driving and even saving you money on insurance[3].

Evidence in Accidents: Dash cams can capture clear footage of the road ahead, which can be invaluable in case of an accident. This footage can help determine fault and support insurance claims.
Deterrent to Bad Driving: Knowing that their actions are being recorded can encourage other drivers to behave more responsibly on the road.
Insurance Savings: Many insurance companies offer discounts to drivers who install dash cams in their vehicles.
Parking Mode: Some dash cams come with a parking mode that allows them to record even when your car is parked, providing an extra layer of security against vandalism or hit-and-run incidents.

Choosing the Right Dash Cam for Your Car

Before you start the installation process, it’s crucial to choose the right dash cam for your needs. Here are some factors to consider:

Key Components of a Dash Cam

Camera Lens: Look for a high-resolution camera that can capture clear video, especially in low-light conditions.
Memory Card: Ensure the dash cam supports a micro SD card with sufficient storage capacity to hold several hours of footage.
Power Source: Decide whether you want a dash cam that can be powered via a cigarette lighter or one that needs to be hardwired to your car’s fuse box.
Additional Features: Consider features like GPS, Wi-Fi connectivity, and a rear camera for added security[3].

Types of Dash Cams

Basic Dash Cams: These record the road ahead and are the most common type.
Dual Dash Cams: These include both a front and rear camera, providing a comprehensive view of your surroundings.
Smart Dash Cams: These often come with advanced features like lane departure warnings and forward collision alerts.

Step-by-Step Installation Guide

Installing a dash cam is relatively easy and can be done by anyone with some basic DIY skills. Here’s a detailed guide to help you through the process:

Step 1: Choose the Perfect Spot

The best spot for your dash cam is usually on the windshield, just behind your rear-view mirror. Ensure it doesn’t obstruct your view of the road, as this can lead to fines or even fail your MOT in the UK. The UK Highway Code specifies that nothing should intrude more than 40mm into the area swept by your windscreen wipers[3].

Step 2: Mount the Dash Cam

Peel off the adhesive liner and firmly press the camera against the windshield for at least 30 seconds to ensure it adheres properly[4].

Step 3: Connect the Power Cable

You have two main options for powering your dash cam: using a cigarette lighter or hardwiring it to your car’s fuse box.

Using a Cigarette Lighter

This is the easiest method. Simply plug the power cable into the cigarette lighter socket, and your dash cam will start recording as soon as you turn on the ignition.

Hardwiring to the Fuse Box

For a more permanent and reliable solution, you can hardwire your dash cam to your car’s fuse box. Here’s how:

Connect to the Fuse Box: Use a fuse tap to connect the camera’s power cable to the fuse box. This will allow the camera to receive power directly from your car’s electrical system[1][5].
Choose the Right Fuse: Select a fuse that provides power when the ignition is on (ACC) and another that provides constant power (BAT) if you want to enable parking mode. For example, in a BMW G20, you might use fuse 74 for ACC and fuse 38 for BAT[5].

Step 4: Install a Hardwire Kit (If Necessary)

If you choose to hardwire your dash cam, you may need a hardwire kit. This kit usually includes a car battery protector to prevent your car battery from draining.

### Example of Hardwire Kit Components
- Hardwire cable
- Fuse taps
- Car battery protector
- Mini fuses (e.g., 5A, 10A)

Step 5: Configure Your Dash Cam Settings

Once installed, configure your dash cam settings. This includes setting up the recording mode, adjusting the sensitivity of the G-sensor, and connecting your dash cam to your phone via Wi-Fi or Bluetooth if available.

Understanding How Dash Cams Work

Loop Recording

Dash cams typically record in short segments (usually around three minutes) and overwrite older footage when the memory card is full. This ensures continuous recording without running out of storage space[3].

G-Sensors and Impact Detection

In the event of an accident, the G-sensor in your dash cam detects the impact and saves the footage leading up to the incident, locking the file to prevent it from being overwritten.

Parking Mode

For dash cams with parking mode, you need a constant power source. This can be achieved by hardwiring the camera to your car’s fuse box and using a fuse that provides constant power[3].

Legal Considerations in the UK

While dash cams are legal to use in the UK, there are some important considerations:

Positioning: Ensure your dash cam does not obstruct your view of the road. It mustn’t intrude more than 40mm into the area swept by your windscreen wipers[3].
Audio Recording: Capturing audio without consent can be a breach of privacy. It’s advisable to mute the audio function on your dash cam to avoid legal complications.
Privacy: Be mindful of where you’re pointing your dash cam, especially in areas where individuals have a reasonable expectation of privacy, such as private property[3].

Viewing and Managing Your Dash Cam Footage

How to View Footage

You can view your dash cam footage directly on the camera’s screen, on your phone via an app, or by transferring the files to a computer.

Managing Storage

The amount of footage you can store depends on the capacity of the micro SD card and the recording settings of your dash cam. Here’s a rough guide:

Memory Card Capacity	Estimated Recording Time
32GB	4-6 hours
64GB	8-12 hours
128GB	16-24 hours

Practical Insights and Actionable Advice

Tips for a Smooth Installation

Disconnect the Battery: If you’re installing both a front and rear dash cam, it might be wise to disconnect the battery to avoid any electrical shocks or damage to your car’s electrical system[5].
Use the Right Tools: Ensure you have all the necessary tools and components, such as fuse taps and mini fuses, before starting the installation.
Consult Your Car’s Manual: Understand your car’s electrical system and fuse box layout to avoid any mistakes during the installation.

Common Mistakes to Avoid

Incorrect Fuse Tap Orientation: Make sure to orient the fuse tap correctly to avoid any electrical issues. The power side of the fuse tap should be connected to the fuse that provides power when the ignition is on[5].
Overlooking Parking Mode: If you want to use the parking mode feature, ensure you connect the dash cam to a fuse that provides constant power.

Installing a dash cam in your British vehicle is a straightforward process that can significantly enhance your driving security. By choosing the right dash cam, following the step-by-step installation guide, and being aware of the legal considerations, you can ensure that your dash cam works effectively and provides you with the peace of mind you need on the road.

As one user on the G20 BMW forum noted, “Been a week now & everything is working fine for me. Hope this post helps many others, Happy driving, peace ☮️”[5].

With the right dash cam and proper installation, you can drive with confidence, knowing that you have a reliable witness to any events on the road.
