Cobra SC 400D review

The SC 400D leans on software as much as hardware. The front camera records 4K UHD through a glare-reducing polarized filter, and the D version adds a rear camera with an extension cable in the box, with an optional 1080P cabin camera if you want a third view. Cobra's Drive Smarter app is the differentiator: it shares alerts for red light cameras, speed traps and road hazards from Cobra's driver network, works with Apple CarPlay and Android Auto, and builds incident reports with video that you can send to an insurer. Mayday Alert emails and texts a contact you choose if the camera senses a severe impact. Built-in Wi-Fi handles cloud storage and sharing, and a microSD card comes preloaded. Against that, the product page does not state rear camera resolution or sensor, and buyers on Cobra's own site rate it 3.6 out of 5. We compared documented features and published prices.
