Prime Day is an excellent chance to grab a dash cam deal, and the one that has caught my eye in the October sales is the Terensoui 4K + 4K Dash Cam for just $109.99 at Amazon. That's an incredibly low price for a model that boasts 4K front and rear cameras, GPS, G-sensor, 5.8GHz Wi-Fi, and more, with a 128GB memory card thrown in for good measure.

To be clear, I've not personally used the Terensoui dash cam, although a review sample is on the way and I'll share an in-depth TechRadar review in due course. I'm not being drawn into the 70% discount either, which seems slightly inflationary. However, $110 for the features this dash cam has looks like unbeatable value, should it score anywhere close to the 4.9-star average Amazon user review rating.

It's the final day of the sales, so do also check out TechRadar's Amazon Prime Day live coverage for the best tech deals before they are gone.

The Terensoui 4K + 4K Dash Cam comprises front and rear 4K dash cams, a suction cup mount with GPS unit built-in, car charger, 21ft rear cam cable, trim tool, and 128GB micro SD card. Should you want the 24-hour parking mode feature, the optional hard-wire kit is an additional purchase.

I don't make the habit of recommending products I've yet to try, but all the signs point to a capable dash cam for an incredible price. The Terensoui dash cam is packed with the kind of tech you'd expect from one of the best dash cams in 2025, including dual 4K cameras.

In fact, Terensoui seemingly goes one better than most – the front camera has a 3-inch display, while the rear camera is also 4K. Most other models' rear cameras usually top out at 1080p.

There's also a night vision mode, built-in G-sensor (which protects files when an incident is detected), built-in GPS (the unit is inside the mount and not the camera), and 5.8GHZ Wi-Fi for fast download speeds.

Parking mode capability is included, too, though, like most dash cams, you'll need an optional hard-wire kit to gain this function. And you can preview video and customize settings using Terensoui's app, available for Apple and Android devices.

To get all of this for $110 is a steal, and I look forward to finding out if the Terensoui dash cam lives up to its promise. I've rounded up other standout dash cam deals for models we've tested, below.

A watered-down version of the pro model could be the better pick if you don't need the latest model's updated features, especially now that it drops to $100. The rear camera tops out at 1080p versus the 2K in the Pro model, which also has beefier dual-band Wi-Fi.
