I found with the with of the A139 i have had to move it a long way to the left in my car, even off the frit area. if i dont it take the space of 2 cameras, and i dont want to move it again when i get the next cameras.
And i have a feeling the A139 will be in my car for some time to come.
But TBH i dont mind as i dont feel the A139 are that visible, or maybe after having so many cameras on my windscreen for so long, the stealth ( actual ) aspect are not that big a deal for me any more.
But regarding the cameras it is still a big thing in my book, and if i placed the A139 so the lens was right smack in the sweet spot and with most of the camera up on the frit, it would still be a stealthy install.
So in regard to stealth i still call the A139 as good, but a little case sensitive depending on the car & windscreen topography, but that is more or less the same with any dashcam.
I do think if the pill shaped remote cameras was meant for installing upright you could get a bit more creative in mounting them, this would ( with the right mount ) also make it possible for the cabin camera to be turned L or R to face the side window.
At least that is one of my brain farts about the A139 so far
I am sort of wishing too that the 2 remote camera wires both had a 90 deg plug in one end.
But in general i feel it have a good chance to do well for viofo.
I do hope they can enlist some modders to dial in the IQ as i am sure it can be a made better.
I am still a fan of being able to see the LCD screen when installed, but that is just for testing, if i feel good about the system i dont matter if i can not see it, So the A139 not having a screen was only a problem for me the first 2 days or so.
Not tested how the A139 sound off if there is a issue of some sort, i will have to power it up without a memory card in it one of these days, but i feel confident even with very little redundancy on my windscreen at the moment.
My only dashcam woes ATM are my side cameras, the K2S system do not want to play ball with me anymore, so my plan are to move the DR system there and put other lenses on the cameras if i can source some wider FOV ones that still mount well in the little camera housings.
