I agonized for ages over which dash cam to buy. There are so many on the market that it became really difficult to make a decision. Eventually I plumped for the DX20. On paper it had everything, HD video recording, Ambarella solution plus speed camera alerts – what’s not to like? Well, the first thing I noticed when it arrived was how nicely it was all packaged and the unit itself is really well made with a glossy black finish. A really nice looking product. It looks really nice in my car too and works as well as looks. It tells you how fast you are going and the screen changes to show alerts to speed cameras whenever you approach one. The speed camera database seems really accurate and is already on the device when it’s delivered which is handy (although this can be updated free of charge too – another bonus) You can play video you have recorded on the device but if you want to really see everything that is happening, you can play it on your computer. Video is really clear and I was surprised at how clear the audible recording was. It only has a tiny microphone but the quality is excellent. All in all, this is a quality piece of kit!
