Digital Camera World Verdict

The Cobra SC 400D is a fantastic dash cam with very high-quality 4K footage, integrated GPS, Alexa built-in and the option to fit a second or even a third camera for rear and interior recordings. This is quite a large product, however, so might not be suitable for drivers of small cars with shallow windscreens. It’s expensive, at $330/£300, but for outright video quality it’s hard to beat.

The biggest features of this dash cam are its 4K video resolution and connections for two extra cameras. 4K dash cams aren’t new, but they tend to overpromise and underdeliver, with footage that ticks the box for Ultra HD resolution, but suffers when it comes to exposure, white balance and grain. Although it has a high price, the Cobra SC 400D hopes to deliver on its 4K promise.

Another key feature is how the Cobra can connect to two further dash cams at once. The kit reviewed here comes with a rear-facing camera, while another, intended for viewing the interior, can also be purchased and added to the system.
