This review will be a work in progress so be patient please. If you have any questions I'll try to answer them for you. ATM this cam is in Beta testing so what I post here will reflect any changes made in later units as they occur.
First the install. It was fairly easy but as with any dual-remote cam there are lots of cables to contend with. The one's you'll probably use with this can are all on the left side, and there is a cable retainer which can be added there to prevent them from pulling out. The MicroSD card is on the right and is rather deeply recessed meaning most folks will need something like a small stick to insert and eject the card. It was done this way so that the manual on-off-auto switch prevents the card from being lost when the cam is on, as it covers that port slightly. I didn't really have any problems with personally. The main unit mounts into a clip which can be screwed down, affixed with the supplied 3M tape, or held by a 'pocket clip' which can be oriented vertically or horizontally. The main unit pops in and out of the clip easily, but is held firmly in use with 2 'nubs' which engage slots. It seems firm enough to last. And though I didn't use it, this cam comes with a magnetic 'ball joint' type mount for the cam clip. The base is magnetic with the ball having a 3M tape mounting. It swivels in any direction over about a 160 degree range so that you can adjust the screen viewing angle however you like it. You can separate the ball from the mount should you need to move the screen. I imagine this mount could also be used with one of the cams if you desired, and there's a supplied 3M tape for the plate if there's no metal to stick it to. There is also a 1/4-20 standard tripod thread socket on the main unit giving you 5 different ways to mount it.
The came comes with an OBD2 PS adapter as well as the usual cigarette-lighter type. Note well that you must use only these power supplies and no others as the audio amp can be damaged if there is any connection between the cable's shield and the car ground through the power supply! I used my DMM to check the Anker PS I wanted to use and found a 4ohm connection to ground from shield, so I'm pretty sure most other PS's and hardwire kits will be similar. I also found the ciggie adaptor body too short to make contact in both my triple-tap socket and my van's factory ciggie lighter socket. My old bus is OBD1 so I couldn't test that unit, but it seems to be working for other testers. I do expect there will be some changes here with production models and I will edit and amend this paragraph if needed to reflect those. It is necessary to use the OBD2 PS for parking modes. With most cars, using it will also allow you to display a virtual gauge cluster showing Speed (MPH or KPH), engine RPM's, and throttle position as well as the car's battery voltage.
For me, the main attraction of this dashcam is it's remote cam modules. These things are tiny compared to all others and can be mounted in cars where no other cams will easily fit. They mount with 3M tape, and extra tapes are supplied. The cable exits from the left side of the module as viewed from it's back and if these have any drawbacks that might be it, as the cable will need some space to bend if placed in a narrow location. The cams can be 'rotated 180 degrees' individually in the menu, and the image is 'reversible' left to right as you'd need with a backing-cam. There is also no lateral adjustability with these. Future plans include optional waterproof, illuminated IR, and waterproof reversing cam modules which will make this as versatile a dashcam as has ever been made. These are connected with USB-C type cables, and the cam comes with 2x 2m cables, 1x 4m cable, and 1x 6m cable. I was amazed to find that I had cable left over from the rear of my extended-body workvan to the sun visor where the main unit is temporarily mounted. I cannot envision anyone needing to purchase any more cables to install these in any vehicle as you must do with some other cams.
Also supplied is a thin 'puck' style GPS module which can be attached to glass or the dash to with supplied 3M tape. It has a blue LED power indicator around the circumference which can be switched off in the menu, same as all other indicator lights with this cam. The owner's manual is in English, easy to understand, and with many full-color pics and line drawings which cover everything very well. The printing is rather small for my old eyes, but that is the case with most dashcam manuals now. There are a huge number of functions with this cam which can be selected via the menu. Rather than list everything this cam can do I'll mention the one thing is doesn't- there is no buffered parking mode here, and most parking modes require a hardwire kit to function, but this cam does about anything else you'll find in any dashcam. And there's more than usual adjustability of video settings as well. Audio recording and speaker sound are good, and so far the images are too. I'll add clips later on once I update the firmware. The menu layout is simple enough and easily worked with, but with all the available settings and options can feel overwhelming for a newbie. I'll dig into those later on, but the default settings were close to my liking so I had little to do there before using the cam.
I have often said there was no perfect dashcam and never would be, but this one is as close to that as any I have ever known of in my 5 years of using and studying dashcams. The only things I can see which might be wanted is higher resolution (which is not all you'd expect from it) and a buffered parking mode (which only a few cams have). It still needs some testing and development, but everything I see so far indicates that what it needs is do-able so hopefully it will be available to everyone soon.
