What are Dash Cams?

Dash cams are like your own, little, personal road warriors. They're these awesome little devices that you can stick on your car's dashboard or windshield to capture all the crazy stuff that happens while you're out there conquering the roads. They're basically your second pair of eyes on the road, recording everything from "fender benders" through to jaw-dropping scenic drives through the peak district.

Dash cams can actually come in super handy when it comes to insurance claims, proving your innocence in case of an accident, or even catching some wild action on the go. So, if you're all about capturing epic moments and keeping yourself protected, a dash cam will be your new favourite sidekick on the road.

How Does a Dash Cam Work?

Dash Cam, Dash Cams

Okay, so if you don't know what a dash cam is - here's the lowdown on how dash cams work and what they're all about.

Dash cams are clever little devices equipped with cameras that record anything and everything that goes down while you're cruising around in your vehicle. They continuously capture video footage of the road ahead (and sometimes the rear as well) as you drive. This footage is stored on a memory card or internal storage, creating a visual record of your journey.

Dash cams are like your personal eyewitness, providing valuable evidence in case of accidents, insurance claims, or any unexpected incidents on the road. They're all about keeping you protected, giving you peace of mind, and capturing those crazy moments that you can share or look back on later. So, whether you're a thrill-seeker, a cautious driver, or just someone who wants an extra layer of security whilst driving, a dash cam has got your back and is ready to roll with you, anywhere.

Are Dash Cams Legal?

Yes, dash cams are legal in the UK.

Using a dash cam to record video footage while driving is generally considered legal, as long as it complies with data protection laws and privacy regulations. However, there are a few important guidelines to keep in mind. The Information Commissioner's Office (ICO) has issued recommendations for the use of dash cams, which include using them responsibly, respecting the privacy of others, and using the footage only for legitimate purposes.

It's also essential to ensure that the dash cam does not obstruct your view of the road, and you should avoid recording audio without consent, as it may infringe on further privacy laws. Here at Road Angel, we recommend familiarising yourself with the specific regulations and guidelines in your area, as they can vary slightly depending from region to region.

How Long Does Dash Cam Footage Last?

The duration for which dash cam footage lasts is dependent on a few factors: the storage capacity of the memory card, the video resolution and quality settings of the recordings, and whether the dash cam is set to overwrite older footage when the storage is full.

The vast majority of modern dash cams typically use loop recording, which means they continuously record in a loop, overwriting the oldest footage when the memory card storage is full. This ensures that you always have the most recent recordings available. The length of the loop depends on the size of the memory card and the resolution settings.

For example, with a 32GB memory card and recording at 1080p resolution, the footage can last approximately 4-6 hours. However, if you reduce the resolution or lower the quality settings, you can extend the recording time, although we typically advise against this to conserve the quality and viability or the footage. Additionally, some dash cams have options to adjust the loop duration or set specific file sizes for each recording segment.

If an incident occurs, it's important to save the relevant footage immediately to prevent it from being overwritten, but most dash cams have features like "emergency recording" or "incident lock" that protect specific files from being deleted during the looping process.

Does a Dash Cam Record Audio?

Dash Cam, Dash Cams

In the UK, the use of dash cams that record audio is generally allowed, but there are some considerations to keep in mind. The Data Protection Act and the General Data Protection Regulation (GDPR) govern the collection, storage, and use of personal data, including audio recordings.

According to the Information Commissioner's Office (ICO), if you use a dash cam with audio recording capabilities, you should be cautious about capturing conversations or other private information without consent, as it may infringe on the privacy rights of individuals. It is generally recommended to inform passengers or individuals who may be recorded that audio is being captured.

When using a dash cam in the UK, it is important to strike a balance between your legitimate interests in recording for safety or evidence purposes and respecting the privacy of others. It's a good practice to review and follow the guidelines and recommendations provided by the ICO to ensure compliance with data protection laws.

Does a Dash Cam Need Wi-Fi?

No, a dash cam does not necessarily need Wi-Fi to function. Dash cams primarily operate as standalone devices that record video footage onto a memory card or internal storage. The absence of Wi-Fi connectivity does not impact their core functionality to work as a dash cam.

However, some modern dash cam models do offer Wi-Fi capabilities as an additional feature. Wi-Fi connectivity allows you to connect your dash cam to a smartphone or other compatible devices through a dedicated app. This enables you to transfer footage wirelessly, view real-time recordings, adjust settings, and sometimes even access additional features or settings on your dash cam.

Can a Dash Cam Record All Night?

Yes, many dash cams have the capability to record continuously throughout the night. However, it depends on the specific features and settings of the dash cam.

Dash cams typically use loop recording, where they continuously record video footage in segments or loops. When the storage space is full, the oldest footage is overwritten with new recordings. This loop recording feature allows dash cams to continuously capture footage without requiring manual intervention.

To ensure continuous recording through the night, it's important to consider a few factors:

  1. Power source: Ensure that your dash cam is hardwired to the electronics, so that the dash cam remains active even when the vehicle is turned off. Special hardwiring kits are available so you can achieve this.

  2. Memory card capacity: Make sure to use a memory card with sufficient storage capacity to accommodate the desired recording duration. High-resolution recordings and longer recording times require larger memory cards.

  3. Parking mode: Some dash cams have a specific parking mode feature designed to monitor and record events when the vehicle is parked. This mode uses various methods to detect motion or impact, such as G-sensors, motion sensors, or time-lapse recording. When an event is detected, the dash cam is triggered to start recording, capturing any incidents or unusual activity that may occur around the parked vehicle.

Does a Dash Cam Work with Tinted Windows?

Dash Cam, Dash Cams

Dash cams can work effectively with tinted windows, as long as you consider proper placement and choose a dash cam with suitable features for different lighting conditions. It's recommended to refer to the dash cam manufacturer's guidelines or consult their customer support if you have any concerns about using a dash cam with tinted windows.

  1. Placement: It's essential to ensure that you mount the dash cam in a position that provides an unobstructed view of the road. Avoid mounting it directly on heavily tinted areas, such as the darkest portion of the window or on highly reflective tint film, as this may affect the clarity of the captured footage.

  2. Lighting conditions: Tinted windows can affect the amount of light that enters the vehicle. In low-light or nighttime conditions, the tinting may reduce the overall brightness, which can impact the clarity and visibility of the recorded footage. It's important to choose a dash cam with good low-light performance or night vision capabilities to mitigate any potential issues.

  3. Infrared (IR) filters: Some dash cams use infrared (IR) filters to enhance the image quality in challenging lighting conditions. If your tinted windows have IR filtering properties, it may affect the effectiveness of the IR filter on the dash cam. It's advisable to check the compatibility of the dash cam with tinted windows and IR filters if you specifically require that feature.

How Are Dash Cams Powered?

Dash cams are typically powered through 1 of 3 different methods. The most common power sources for dash cams include:

  1. Cigarette lighter adapter: Many dash cams come with a power cable that can be plugged into the vehicle's cigarette lighter socket or accessory power outlet. This method allows the dash cam to draw power from the vehicle's electrical system while the engine is running. The cable may have a built-in power adapter or voltage regulator to ensure the proper power supply to the dash cam.

  2. Hardwiring: Hardwiring is an alternative method that involves connecting the dash cam directly to the vehicle's fuse box or electrical system. This method provides a more permanent installation and allows the dash cam to receive power even when the vehicle is turned off. It typically requires a dash cam hardwiring kit that includes a power cable, fuse taps, and connectors. Hardwiring often involves connecting the dash cam to an accessory or constant power source, depending on the desired functionality and parking mode capabilities.

  3. Battery-powered: Some dash cams have built-in batteries that can power the device for a limited time without the need for a constant external power source. Battery-powered dash cams are typically used in parking mode or when the vehicle is turned off. However, it's important to note that the battery capacity may vary between models, and continuous use may drain the battery relatively quickly. In such cases, it is necessary to recharge the dash cam periodically or connect it to a power source for extended use.

Does a Dash Cam Work When the Car is Off?

Yes! At Road Angel, we prefer state-of-the-art dash cams that are hard-wired, but utilise parking mode. 

Parking mode is a feature available in many dash cams that allows them to continue recording even when the vehicle is parked and the engine is turned off. It provides an additional layer of security and surveillance for your vehicle while it is unattended.

When activated, parking mode utilises various methods to detect events or motion around the parked vehicle. Common detection mechanisms include:

  1. G-sensor: The G-sensor detects sudden impacts or movements, such as a collision or someone bumping into the vehicle. When an event is detected, the dash cam is triggered to start recording and save the footage.

  2. Motion sensor: The motion sensor detects changes in the surrounding environment, such as movement in front of the vehicle. If motion is detected, the dash cam starts recording to capture any relevant events.

  3. Time-lapse recording: Some dash cams use time-lapse recording in parking mode, capturing frames at specific intervals to conserve storage space while still monitoring for events. When an event occurs, they switch to regular recording to capture detailed footage.

Parking mode is particularly useful for capturing potential accidents, hit-and-runs, vandalism, or theft attempts that may occur while your vehicle is parked and unattended. It provides valuable evidence and can help identify perpetrators or determine liability in case of an incident.
