Even if you’re not into gadgets, you’ll have noticed that other people seem to be using dashcams. As a result, social media now has even more hilarious clips of people attempting to park, worrying footage of bad driving, road rage and so on. But if you have no plans to make your own YouTube clips, why might you need a dashcam in your motorhome?

With cameras on the corner of so many urban streets, it’s easy to forget that Britain’s countryside is largely surveillance-free. While this is refreshing, if somebody accidentally crashes into your motorhome, it means there’s no CCTV footage – and there are probably no actual witnesses – to back up your insurance claim.

Without detailed proof of the rights and wrongs of an accident, you’re quite likely to end up with a ‘knock-for-knock’ deal between the insurance companies – which is bad news in terms of the hassle factor and is likely to hike up your premium next year. How unfair.

Of course it’s even worse if the other driver doesn’t stop, or if you’re injured.

Some insurance companies are now offering discounted insurance premiums to drivers who install dashcams in their vehicles, because it makes any claim so much easier and quicker to sort out.

So, if you’re shopping for dashcams, what’s on offer?

The best dashcams assist the driver in many ways. If you can afford it, buy a dashcam with GPS, because this enables it to overlay the images of any impact with the exact location, time and date.

There are plenty of other desirable features to look for when you’re shopping for dashcams. We’d want the ones that give you speed camera alerts and tell you if you’re driving too fast, drifting out of your lane (and possibly falling asleep at the wheel), and if the vehicle in front has braked suddenly. 

The way in which dashcams work is that they film the road ahead as you drive, automatically. When the camera card is full, they simply overwrite it in a continuous loop. But, thanks to motion sensors in the device, if any impact is detected the dashcam will save the footage before, during and after the incident, and record all the relevant GPS and mapping data at the side of it. Some of them also have a ‘parking mode’ and a battery, so that if someone crashes into your ‘van while it’s parked, the device will start recording automatically. 

Given the amazing camera quality in most dashcams, numberplate recognition is usually possible even at night. Hit-and-run motorists, beware! We’re convinced – dashcams are worth having on board, if you get the right one.

We’ve tested a wide selection of dashcams in Practical Motorhome, such as the entry-level Cobra CDR 820 and the feature-rich Cobra Drive HD CDR900, the Transcend DrivePro 220Snooper DVR-4HD, the excellent Mio MiVue 538 Deluxe, the Next Base iN-Car Cam 521G and the combined dashcam and sat-nav package, the Garmin nuviCam LMT-D.

The  Blackvue DR650GW-2CH costs £289.99 and records the rear view as well as forward view – but there’s a major problem. Sometimes termed as professional dashcams, models such as this don’t seem to offer a lot at first glance. There’s no screen at all, so if you want to view the coverage you’ll have to hook it up to a smartphone via Wi-Fi .

It’s also missing a plethora of features, such as forward-collision warnings, which most premium dashcams have.

The integral GPS simply monitors and records speed and positional data.

But, that said, visually, the output is superb. This model’s most interesting feature is a second camera for the rear window, complete with a length of coaxial cable physically connecting it to the front unit.
