Z-Edge T4

Z-Edge T4

The T4 is a dual channel dash cam released in Jul 2018 by the Chinese manufacturer Z-Edge. This reasonably priced dual dash cam is popular on Amazon and has many positive reviews.

The Z-Edge T4 is based on the Novatek NT96663 processor. It uses a Omnivision OV4689 CMOS sensor for the front camera and a SC2133 CMOS sensor for the rear camera. While the Novatek processor and Omnivison sensor are in quite common in other dash cams, this is the first time we have heard of the SC2133 sensor for the rear camera.

Video Quality

The front camera records 1080p video at 30fps. Video quality for the front camera during the day is good and night quality is average. While not the greatest video quality, most owners will find it acceptable. The rear camera records 1080p video at 30fps. The average bitrate for both front and back streams together is 12.1 Mbps.

The rear camera has slightly worse video quality than the front camera but it is still reasonable. The video is good during the day and average at night. If you choose only to run the front camera and not the rear camera, you can select 1440p resolution which improves the video slightly. We recommend running both cameras at 1080p since that will give you more coverage.

Features

The most unique feature of the Z-Edge T4 is the large 4″ touchscreen. This is one of the few dash cams sold outside of Korea that makes use of a touchscreen. In Korean market, large touchscreen cameras are quite popular, but outside Korea, demand for these larger cameras is not as high. Most Korean manufacturers only market their smaller more discreet cameras to North America and Europe due to this preference.

That being said, the Z-Edge T4 touchscreen is excellent. It is very responsive, very easy to use and has big icons to access available features. For someone looking for an easy to use camera with a big screen and big buttons, the T-4 hits the mark.

The camera has a g-sensor and comes with a 32GB MicroSD card. It does not have GPS or WiFi. The T4 provides non-buffered parking mode if you hardwire the dash cam to your vehicle (optional hardwire kit required).

The camera comes with a suction mount that can swivel 360° to record interactions at your side windows (i.e. police traffic stop). As previously mentioned, the T4 is a very large dash camera at 122 x 71 x 30mm. The size plus the suction mount make this a very visible camera from outside the vehicle.

The build quality is very good and reliability has been above average. Unfortunately the T4 does not come with audio error notifications, only error notifications on the screen. It also uses a lithium battery instead of a capacitor making it not suitable for hot environments.

Support

Z-Edge appears to be responsive to questions and comes with an 18 month warranty which is a strong positive. On the negative side we have not seen any firmware updates for this camera since it has been launched.

We would like to thank our members Sunny and Paul Iddon who reviewed the Z-Edge T4 on our forum.

Known Problems

While there do not appear to be any systemic problems with this camera, some owners have indicated the camera stops working / recording / reboots. There is no known solution but there problems do not appear to be widespread.

Should I Purchase?

The Z-Edge T4 is one of the few touchscreen dash cams currently available and the touchscreen features are implemented very well. Video quality during the day will be good for most owners but night video could be a bit better but it is acceptable. The 18-month warranty, included microSD card, good build quality and reasonable reliability are all positives.

While we prefer smaller, more discreet dash cams, the T4 is a camera to consider if you want a large, easy to use touch screen. The lack of WiFi, no audio error notifications and usage of a lithium battery instead of a capacitor are drawbacks. Overall a reasonable dual camera for the money if it fits your needs.
