Is there anything else worth looking out for? Cheap microSD cards can work well in some devices, but dash cams need something that’s built to last. If you’re buying a 1440p or 4K dash cam, think about a 64GB or 128GB card, and look for one with a longer warranty or one that’s designed for endurance in continual use. Today’s high-resolution dash cams can use anywhere between 100MB and 500MB per minute, depending on their resolution, so even a 32GB card might only give you up to four hours of recording before it starts overwriting the existing files. We wouldn’t recommend buying a card smaller than 32GB because you could end up running out of space. However, it will generally lock any files where it’s detected any kind of incident, and you can normally lock them manually by pressing a button on the dash cam when you know you’ll want that file. This can be a problem because when most dash cams run out of space they start saving new footage over the existing footage. Most dash cams need a microSD card to store footage, and while some will come with one bundled, they’re often on the small side. You can decide for yourself whether the cost and effort is really worth it. However, the extra camera or cameras will need to be wired up to the main unit, which can mean running huge lengths of cable between the front and back of your car, often along the windows or under the floor mats. A rear-view camera can prove handy to capture a shunt from behind. Some even include three cameras, with one recording the view through the windscreen, another the view through the rear windscreen, and a final camera recording what’s going on inside the car – often with infrared lighting for visibility after dark.Īdditional cameras can be useful, especially if you’re a professional taxi, Uber or delivery driver, and you want a record of what happens in the vehicle. Many dash cams now come in single- or dual-camera versions, with the dual cam version fitting in a second camera into the main unit, or including a smaller camera that you can fit to the rear windscreen. With these, you use your smartphone to position and adjust the camera, and you can even use the app to review and protect footage or even upload it to the cloud.

What’s more, many dash cams are now designed to work in concert with a smartphone app, communicating via Bluetooth and/or Wi-Fi. These are useful when you’re setting up the camera, but not essential once that’s done. Some even have special driver-safety features to help you avoid that happening.Ĭheaper models may do away with extras such as a live-view screen. What’s more, they may have more advanced features to detect a collision and safeguard any relevant footage, along with built-in GPS to help them track your speed and position, which could be useful if you’re involved in an incident. Premium dash cams will have 1440p or 4K resolutions, higher frame rates, better-quality lenses and video quality enhancements that are designed to ensure you get the clearest, smoothest footage possible.
