The Z-Edge T4 Deal Lens Dash Cam sits high and pretty on its specs. Featuring a large 4-inch touch screen display, a wide angle 155-degree lens, wide dynamic range and the capability to record through not only the front camera at 1440p, but there is also a separate rear camera that will record at 1080p.
Finally to top all this off, there is a 32GB SD card included in the box too. This is a lot of tech and features for your money. But does all of this make a great camera? I had high expectations before unboxing the Z-Edge T4.
Inside you’ll find the camera itself, which appears very large in size when you’re used to dash cams of half its size. Its 1080p rear facing camera is a size that’s more inline with cameras you would put up in the front windscreen, but its soul purpose is to record all the action from its attachment on the rear windscreen.
You get a 26-foot mini-USB cable (not micro) to run between the rear camera and the front camera, then you have another cable to run between the front camera and the supplied dual USB car charger that is also included in the box. With all these wires you also have a handful of clips to attached these cables to, along with a plastic tool to help wedge the cable between or behind any interior lining.
Once powered up the Z-Edge T4 chimes into life and your attention is immediately drawn to its large 4-inch colour touch screen display. Once you’re used to tiny 1.5-inch displays on smaller dash cams, or even no displays at all, the T4 is huge in comparison.
For me, the 4-inch display is a little too big to be mounted on the windscreen. I prefer my tech to be hidden, tucked away from sight, and be far less of a distraction whilst I am driving. With that said though, I did like the bigger screen when interacting with its many options, but how often do you do this after they have been set to the desired settings.
The Z-Edge T4 carries a number of options to suit your tastes. First there is a quick menu that’s accessed from the left side of the screen. From here you can set different recording modes: Drive, Scenic, Park and WDR. Selecting Drive mode is an everyday setting optimised for regular use. The Scenic option records video clips for longer and easier post-processing and sharing.
In Park mode the T4 increases its internal G-Sensor and optimises its battery efficiency to monitor your vehicle, whilst its parked. It will then detect and record any bumps your car might get whilst its parked on the street or in a carpark.
Finally there is the WDR (Wide Dynamic Range) mode. This mode optimises low light image quality and minimises screen glare. This is particularly useful during night-time driving, where video captured can enhance dark spots and reduce extreme light from street lamps and oncoming car headlights. In practice though I couldn’t see any major differences during night driving, especially with headlight glare.
Digging down into further menus, you have the ability to adjust recording quality of the front camera, from 1440p 30fps to 1080p 30/60fps and 720p 30/60fps modes. Loop recording time can be adjusted from 1, 3 and 5 minutes, whilst in the frequency area you can switch between 50 and 60Hz modes for smoother video recording.
A nice feature (that would be most welcome in other dash cams) is the ability to adjust exposure manually from the settings menu. From 0 you can go up to +2 exposure for more light into the sensor, and down to -2 can be set to allow less light into the sensor. Increments of 0.3, 0.6, 1.0, 1.3, 1.6 and 2.0 can be set up and down the range. Ideally you want this to run dynamically, but overriding the exposure is great if you find your videos to be too light or too dark in their overall contrast. If this is not set right you may lose a lot of detail in day recordings or at whilst driving at night.
Attaching the camera is done through a simple but effective suction cup and locking mechanism. It’s a classic mounting solution that just works, and during its testing time it never lost its suction. I prefer this over the 3M sticker mounting solutions, especially when I have to remove it! Once mounted the camera can be tilted back and forward in the mount, as well as side by side in the mount itself.
A 32 GB SD card comes supplied with the Z-Edge T4, which is great to instantly get this dash cam up and running. A 32GB SD card doesn’t break the bank these days, and it is a simple token gesture to have this included in the box. If you prefer to store more recordings for longer, then this dash cam supports up to 128GB class 10 or higher micro SD cards.
So with the externals and features covered, how does it record video? On first impressions, it’s good, but with high expectations of a dash cam capturing at a 1440p resolution, as soon as I reviewed the footage I was slightly disappointed. This was confirmed even more once I compared the dash camera footage with my current favourite dash camera that we’ve reviewed – the AUKEY DR02.
Comparing the same scene captured on both cameras, side by side, it is a night and day comparison, with the winner being in favour of the technological inferior AUKEY DR02, which captures at up to 1080p 30fps. This is highly likely due to its Sony COMOS sensor. Colours on the Z-Edge T4 are far less natural when compared to the AUKEY DR02. See the comparison below.
Even with a higher resolution, its video wasn’t noticeably sharper. Thanks to its larger housing, the Z-Edge T4 does have a much bigger lens, compared to the more smaller dash cams, such as the AUKEY. With a bigger lens, its field of view is less as spherical, which results in less distortion at the edges. Compared between the AUKEY DR02 the detail is kept much clearer on the Z-Edge T4.
Day and Night recording are a little oversaturated, so this means you need to dial down the exposure setting. What I found though is that at night it required one exposure setting whilst in the day this setting was far too bright, where as with the AUKEY DR02 exposure setting worked both at night and day.
Capturing audio is possible thanks to the small microphone located on the camera housing. Audio recording is much quieter than the AUKEY, with very little bass captured in the audio. Overall it feels like the microphone isn’t as sensitive as its competitors, so if audio is very important for you, this camera isn’t for you.
A common feature appearing in many dash cams these days is the Emergency Recording function. This is when the camera senses any change in movement that is activated by a built-in gravity sensor. This automatically captures unexpected driving incidents, whether driving or parked and locked up. Emergency recordings are then stored and archived where it cannot be overwritten.
The Z-Edge T4 Dash Camera is currently on sale for £139.99 on Amazon, and at this price it is tough to recommend it if I am honest. For £30 less you can get a dual camera setup from AUKEY that carries less specs than the Z-Edge, but as you can see above, it gives just as good results, if not better in certain cases. I have noticed during this test that you do not have to have the best specs to get the best results.
