Z-Edge T4 dash cam review: Great video, a touchscreen, and style for miles, but no GPS

When I pulled the Z-Edge T4 out of its box, I was thinking the company had made a mistake and sent me a digital camera instead. Most dash cams, capable or not, have a rather cheap feel. The T4, on the other hand, has the heft and feel associated with the object I mistook it for.

The T4 is also a very good dash cam with a super-handy 4-inch touch display and a 1080p rear camera. Put bluntly, it’s easily the classiest dash cam system I’ve reviewed. For $170 with a 32GB SD card? Sold. If you don’t need GPS. Dang. For the whole package, the Viofo A129 remains our top pick.

Design and features

Gushing and consternation aside, the T4 is a somewhat large dark gray and silver camera, measuring approximately 4.5 x 2.5 x 1 inch at the lens. As mentioned, it has a huge 4-inch touch display that’s deftly responsive. 

On the top of the camera are the micro-USB power port and the mini-USB port for the rear camera. On the left side of the unit you’ll find the SD card slot (up to 128GB) and the power button. That’s it. The touch display obviates the need for other buttons. The camera sports a 155-degree field of view, and max resolution is 1440p. You can step that down to save storage space if need be.

Note: As to power, there are now OBD II to micro-USB cables available online for around $10, if you want to hardwire the T4 or any other camera without the hassle of splicing or tapping the wiring harness.

The T4’s on-screen interface can’t match that of the PureCam for style, but it’s more efficient, with its large icons and a very well-organized menu system. It’s really a breeze, and with the nicely sensitive touch display—a joy to use.

The camera also features a 180mAh battery, which was enough to keep it chiming in my backpack for a couple of weeks. Alas, the display won’t turn on while the camera isn’t plugged in, so I couldn’t turn off parking mode until I got to an AC outlet. Yes, there’s parking mode, where the camera will use its g-sensor to wake up and record what just woke it up.
