Here's some unboxing pics of the K2S cam which was supplied to me free for beta-testing and review. Full review to follow shortly.

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.

Here's some vids during beta-testing using extreme bitrate and default exposure. My ancient windshield is wiper-scratched and sand-pitted so keep that in mind when viewing.

Just noticed some cars in your video have no front number plates. Are they optional in your area?

In my State only rear plates are issued. This is why I feel a rear cam needs to be as good as a front cam so it can identify a driver's face. With the K2S, both cams are equally good :)

Any idea how much this will cost, and when it will be released?

Update:

I've been using this cam for 19 months now and it has proven to be almost completely reliable as far as recording. Of recent times I did notice last week that it hadn't been starting up or recording every time when I went to review the card. I do note that I hadn't bothered to look at the vids or format the card in a few months prior to this, which I feel shiould be done monthly with any cam. On checking the 64GB Samsung EVO Select card with h2testw and formatting it on PC and in cam it now functions with complete reliability again including overwriting old files. I can't really fault the cam for this; every cam and card needs regular maintenance and if this cam gets that it is utterly reliable :cool:

I have discovered an odd issue which has occurred 4 times now: Without user input it loses the settings I programmed from the menu and reverts to default settings. I have been unable to detect any pattern to this occurring and it's done this with 3 different cards (all were the same type as above with 2 being 64GB and also one being 128GB). Being that I normally can't see the cam while driving, I became aware of the issue when the "speed alert" function started beeping while driving after I had it turned off (having audible warnings is nice!). No recordings were ever lost and the G-sensor still functioned properly so I do not feel that this is a serious flaw, nor am I able to find anyone else who has experienced anything similar.

So in summary I can say without reservation that if you are in the market for a dual remote cam, then the K2S is a most excellent choice due to it's reliability, it's very small remote cam modules, it's super-long included cam cables, it's ability to withstand high heats without shutdowns, and it's good night-time vids from the IMX323 sensors :love: You do need to keep in mind that you can't use just any PS with it, as many are grounded to the shield connection which can destroy this cam, but as it comes with a proper ciggie lighter adapter and a OBD2 type PS (which you do need to use the parking modes) I do not see this as any real shortcoming. I feel totally safe in recommending this cam to anyone needing what it has to offer. The perfect cam has never been made but this one comes close (y)

Though I haven't tried it I would also urge you consider the newer K2S Pro which is essentially the same device but with the better IMX291 Starvis sensors which offers better vid quality day and night.
