Dashcams provide several benefits for drivers. The most common reason for getting a dashcam is to protect yourself from legal trouble. Dashcams can provide irrefutable evidence in court cases, and they can exonerate drivers who are falsely accused of traffic violations or accidents.

A dashcam can also provide:

  • Protection against fraudulent claims from other drivers in the event of an accident.
  • Proof of who was at fault in the event of an accident.
  • Protection against road rage incidents and other acts of vandalism or violence.
  • The ability to capture beautiful footage while driving (or even while parked).
  • Peace of mind while driving, knowing that you have a record of everything that happens on the road.

Getting a dashcam can end up saving you money in the long run too and can lower insurance rates as well.

Dashcams are small, dashboard-mounted cameras that record video and audio footage of everything that happens while you're driving. Some dash cams come equipped with GPS tracking capabilities and can automatically save footage in the event of an accident.

The purpose of a dashcam is to provide drivers with a record of what happened in the event of an accident or other incident.

Dashcams can be helpful in settling disputes with insurance companies or the authorities, and they can also provide valuable evidence in the event of a hit-and-run accident or other crimes. Some people also find them useful for monitoring their own driving habits or for recording scenic routes.

Most dashcams are small, discreet devices that can be mounted on the windshield or dashboard of a car.

Most dashcams have a wide-angle view to capture as much of the surrounding area as possible. They tend to look similar to regular digital cameras, with a small lens and LCD screen. Some even have Wi-Fi capabilities so that you can download footage directly to your computer or smartphone.

Many modern dashcams also come with GPS tracking, so you can see exactly where you were when an incident occurred.

Many newer model cars can come with built-in dash cams, but there are also many aftermarket options available for purchase, perfect for older models that do not have dashcams built-in.

Dashcams work by recording footage while you are driving. Some dash cams also have motion sensors that will start recording if there is any activity outside the car. This can be helpful in case of an accident or if someone tries to steal your car.

The majority of dashcams are powered by the car's battery, although some models can be plugged into an AC outlet. They typically come with a mount that attaches to the windshield or dashboard, and the camera itself is usually positioned so that it records footage of both the driver and the road in front of the car.

When activated, dash cams start recording video automatically. Many dashcams use a microSD memory card to store the footage captured.

You can then remove the memory card and copy the footage to your computer. Some dash cams also have a WiFi connection, so you can download the footage wirelessly instead.

Dashcams are a great way to capture footage of your drive, and there are two main types: front-facing and rear-facing.

Front-facing dashcams record what's happening in front of the car, while rear-facing cameras record the area behind the car. This is useful for recording accidents or other incidents that occur while you're driving for a more informative picture.

Both types of dashcams work similarly: they consist of a camera mounted on the dashboard or windscreen, and a storage device (usually a microSD card) to store the footage. The footage is usually recorded in MP4 or AVI format, and most dashcams come with software that allows you to view and edit the footage.

Whilst there are a number of different types and brands of dashcams available on the market, most are designed to be installed easily.

Depending on the particular model, the installation might involve mounting the camera to the windshield or dashboard, plugging it into the vehicle's power outlet, and then connecting it to the vehicle's stereo system.

For most, installing a dashcam is a relatively straightforward process that shouldn't take more than a few minutes.

However, it is also possible to hardwire a dashcam directly into the vehicle’s electrical system, which can take time and may require specialist knowledge.

If you're struggling with installation or have any questions about your particular model, reach out to the manufacturer or visit your local autocentre for help.

Ultimately, it comes down to personal preference. Some people choose to remove their dashcam when they park, while others leave it mounted.

If you're worried about someone vandalising or stealing your dashcam, then removing it when you park may give you some peace of mind. Dashcams can be relatively expensive, so it makes sense to protect your investment.

On the other hand, if you live in a safe neighbourhood and don't think there's any risk of your dashcam being stolen or damaged, then leaving it mounted might be the way to go. That way, you'll always have it ready to record footage if needed.

There are a few ways that you can view your dashcam footage. One way is to physically remove the memory card from the dashcam and insert it into your computer. You can then open up the files on the memory card and view them like any other video file.

Another way is to connect your dashcam to your computer via USB and download the files that way. Some more advanced and modern dashcams, such as the T130 3-channel Dashcam, have Wi-Fi capabilities, which means you can connect to them wirelessly and view or download them instantly.

Dashcam footage is typically stored on the camera's internal memory, which can last for a few hours or up to a day.

If the camera is connected to a power source, then it will usually continue to record footage until it runs out of space or the battery dies. Some cameras have an option to overwrite old footage with new footage as it's recorded, while others will save older footage if needed.

You can also keep the footage for longer if you download it and store it somewhere safe, such as on a computer or external hard drive.

Yes, a dashcam can record inside the car only if it has an interior-facing camera.

This can be useful if you're involved in an accident and need to know what happened, or if you want to keep an eye on your passengers. Most interior-facing cameras have a wide-angle lens so they can see all around the cabin, but some may have a narrower field of view that will require adjustment.


Most dashcams do not have audio recording capabilities. However, at Viofo, we believe in capturing the entire situation and the majority of our dashcams have built-in microphones.

Yes, you can use a dashcam as a webcam if it has a USB output so you can connect it to your computer.

However, as dashcams are designed to work whilst out on the road while driving, they will require a constant power source and usually a 3rd party application to play and use as a webcam.

A dashcam can be powered either by a cigarette lighter or by a Hardwire. If you want to use a cigarette lighter, all you have to do is plug it in and it will automatically turn on and start recording.

If you want to hardwire your dashcam, it’s important to follow the instructions that came with it or seek specialist advice from a local auto centre.

If your car has an Auxiliary Power Outlet (APO) that turns off when the engine is off, linking up your dashcam to this will result in the camera shutting down as well.

Yes, you can use a power bank for a dashcam. However, there are a few things to keep in mind.

  •  Make sure that the power bank is fully charged before using it.
  •  Only use power banks that are specifically designed for use with dashcams.

Be sure to disconnect the power bank from the dashcam when not in use.

This typically depends on the dashcam.

Some models may only draw a few amps, while others may draw up to five or more, but it varies from model to model and the resolution of the dashcam.


Dashcams typically record continuously as long as they have power. However, some models may have motion sensing or manual event-recording features that mean they only start recording when triggered.

Some higher-end dash cams come with built-in batteries or can be hardwired into your car’s electrical system, so they can continue recording even if your car is turned off. Some of these can even record for days or weeks at a time.

This means that they require a lot of storage capacity, so they can keep recording for long periods of time. If you’re planning to record for extended periods, make sure to invest in a suitable memory card.


As with all technologies, there is a margin of error associated with speed readings from dashcams. This margin of error can be attributed to several factors, such as the calibration of the device, the positioning of the device in relation to the car, and even weather conditions.

That said, most dashcams are fairly accurate when it comes to measuring speed. Many law enforcement agencies use them as evidence in court proceedings. Therefore, if you're ever pulled over for a speeding ticket and you have a dashcam recording of your car's speed at the time, you may be able to dispute the ticket using that footage.
