Shop all dash camsDash cams record what happens during your car journey. They are great 'eyewitnesses' and the recorded video can be used as evidence following accidents or other incidents driving, which in turn make them very helpful in keeping insurance premiums low. If you're fond of a road trip, a dash cam is also the perfect way to record that memorable journey so that you can look back on it whenever you want.

The quality of the camera in your dash cam will determine the detail that you capture. The higher the number of pixels the sharper the footage captured will be. It is also worth noting that cameras that are of a higher quality will record in higher definition, therefore using space quicker on memory cards. An SD card with higher gigabytes would be more beneficial for dash cams that record in HD. Take a look at the three main dash cam camera definitions below to determine what quality suits your needs:
1080p Full HD
1440p Quad HD
4K HD
This is very useful when making insurance claims. It can pinpoint your location, how you arrived there and what speed you were travelling at.
When your camera detects an impact against your vehicle it automatically saves the footage and prevents it from being overwritten.
If your vehicle is hit while it's parked, the camera switches on automatically as soon as the impact is felt to capture the incident.
Infra-red night vision records clearer images in the dark in areas where there's not much street lighting.
The dash cam starts recording automatically when your car starts to drive.
Once your memory card is full, the dash cam will record over old footage, so it never stops filming. Any important footage can be easily saved and protected.
The SD card is the most vital accessory of a dash cam because no matter how great your dash cam, if the SD card itself fails to record then you have captured nothing. Dash cams will store video on an SD card, which is usually sold separately. Most cameras will record on a loop, recording over old footage once the card gets full. You can save important footage from being taped over by downloading it to another device.
Note that not all SD cards are the same. Dash cam SD cards are designed to:
Most dash cams will take either an SD or Micro SD card. The more gigabytes (GB) a memory card has, the more video it can store before it gets recorded over. If you record at the highest quality, the memory card will fill up quicker. Wondering how long dash cams record for? Here's an example of recording time by memory card size:

You'll be able to immediately view footage on your camera whenever you need to.
You can download your footage to a device to view. You can also send footage direct to your insurer.
Dash cams with no screen will always be W-Fi enabled to allow you to quickly connect, find, and share the clip you need. They will also give you live view.
These frequently asked questions might help:
It is personal preference whether you want a dash cam with or without a screen. A safely mounted dash cam on your windscreen will not be in the visible area, meaning if you place your dash cam in the approved MOT location, you will not be able to see the screen.
Most dash cams come with a hardwiring accessory kit that allows the dash cam to function even when the car is turned off. However, not all hardwiring kits are the same - some will turn on for a few minutes if an impact is detected while others will record in time-lapse to capture 24/7 footage.
Always-on-parking-mode is by far the best option as it will record all night and day. It keeps the dash cam always recording in time lapse mode. This ensures you always record everything even when your car is off. If the G-Sensor picks up movement it will turn the camera to live recording for a few minutes and then back to time lapse. Additional hardwiring kit would be required.
Most dash cams that offer always-on-parking-mode will also have car battery monitoring built-in to ensure you don’t get left with a flat battery. If it detects the battery is dropping below the required voltage it will simply turn off the dash cam and only power it when it detects impact.
