if somebody happens to approach your car from the front, then in that situation, yes, it does seem to do a good job as far as actually tracking that person as they walk around. Additionally, it'll also trigger the rear camera. So, if they happen to go behind the car, the rear camera can also help capture that, too. ▶ 70mai 4K Omni: Can It Really Track Everything? @ 11:53

super capacitor to help handle high heat, which is an improvement over the previous 1080p version uh that had an internal lithium ion battery. ▶ 70mai 4K Omni: Can It Really Track Everything? @ 4:23

camera is slightly out of focus or perhaps not out of focus but just focused very close to my vehicle ▶ How can it be REAL 4K at THIS PRICE | 70Mai A800S Dual Dashc @ 1:57
real 4k sensor has been let down by poor focus and a cheap lens ▶ How can it be REAL 4K at THIS PRICE | 70Mai A800S Dual Dashc @ 3:45

on bright days into direct sunlight things really don't look sharp ▶ How can it be REAL 4K at THIS PRICE | 70Mai A800S Dual Dashc @ 2:36
excessive motion blur perhaps because the camera is operating at a lower frame speed and also perhaps because distant things are out of focus ▶ How can it be REAL 4K at THIS PRICE | 70Mai A800S Dual Dashc @ 4:25
video is a little bit too bright ▶ How can it be REAL 4K at THIS PRICE | 70Mai A800S Dual Dashc @ 4:07
I do notice a bit of vignetting here with the polarizer, kind of blacking out some of the corners while you're driving. ▶ 70mai 4K Omni: Can It Really Track Everything? @ 5:20

Ease of Use (6)

doesn't have a user manual (available online) ▶ Thinkware U3000 4K UHD Dual-Channel Dash Cam | In-Depth Revi @ 3:39
you have to get it hardwired to enjoy some of the best features that it offers such as parking surveillance AI motion control Collision detection and time lapse videos ▶ 70mai Dash Cam Omni - World's First 360 Rotating Dash Cam - @ 6:41
cannot use a dedicated battery pack with the OBD cable, requires hardwiring ▶ Thinkware U3000 4K UHD Dual-Channel Dash Cam | In-Depth Revi @ 3:27
rear camera cable (USB A type) is not compatible with other thinkware models ▶ Thinkware U3000 4K UHD Dual-Channel Dash Cam | In-Depth Revi @ 5:50
you're actually going to be doing so by using the voice commands built into the dash cam. There is no physical button that you can press to trigger the emergency recording. And there's no optional like wireless Bluetooth button that you can pair with the dash cam either. ▶ 70mai 4K Omni: Can It Really Track Everything? @ 14:19
replacement batteries are fairly easy to acquire off of aliexpress but now you need the skills to take open the camera and it just becomes its own headache ▶ How can it be REAL 4K at THIS PRICE | 70Mai A800S Dual Dashc @ 8:34

Features (4)

unlike parking recording, there is no automatic turning to follow different cars or people or anything. If you wanted to record out to the side in case of say a police encounter or something, uh, you do actually need to manually tell the dash cam to turn using those voice commands as well. ▶ 70mai 4K Omni: Can It Really Track Everything? @ 14:44
I don't necessarily know if I could fully trust this and rely on it because there's definitely some instances where it's not going to be capturing what you need because the dash cam is really just going to be looking straight ahead ▶ 70mai 4K Omni: Can It Really Track Everything? @ 16:11
the motion detection only works on the front camera. And this, I think, is actually a big weakness. ▶ 70mai 4K Omni: Can It Really Track Everything? @ 10:44
there is no buffered parking recording. ▶ 70mai 4K Omni: Can It Really Track Everything? @ 13:03

Mounting & Installation (3)

front lens rotation is a bit short for vertical windshield ▶ Thinkware U3000 4K UHD Dual-Channel Dash Cam | In-Depth Revi @ 2:28
a number of people have actually noticed in some of the driving footage uh some vibrations. I'm not sure if that's actually due to the mount or maybe a little bit of play here and kind of like the motorized rotating lens element. ▶ 70mai 4K Omni: Can It Really Track Everything? @ 3:55
there is no uh optional suction cup mount available for this one. It's just going to be uh with this double stick tape mount. ▶ 70mai 4K Omni: Can It Really Track Everything? @ 4:16
