DR900S-2CH

I have personally used the Blackvue 900S (died after 6 years) and now the Viofo A329S (3 channel) which I'm also very happy with. Both have excellent parking modes. Both were hardwired to provide recording while parked. The third channel (fisheye) allows for angles on the side that your front and rear camera won't catch. I opted for the A329 because it allows you to plug in a SSD drive. My micro SD card is 128 gig, the SSD is 2 terabytes. If you're concerned about battery drain, look into getting an external battery pack. I know these things are expensive but once you're involved in an accident, you'll be happy you spent the money.

Whichever unit you end up with, I would go with professional installation. It only adds a hundred or so to the purchase price and the install is cleaner. You'll find it's not rocket science and you can easily see how they did it and replicate in your other vehicles. The reason I say this is of you want it to be truly a passive experience, you'll need a unit with park assist so it can just be active/activateable at all times and the cigarette lighter option does not allow for that. Find a vendor like a stereo isntaller who also sells dash cams. I did that for my first one, a blackvue 900s For my second and third, I installed myself.

Wow that price is criminal. Go to a local car audio/ auto electrician shop. They'll install it for a couple hundy, plus of course the cost of the product its self. I got a top of the range blackview fully installed front and back 4k for just over 1000 bucks

Used a blackvue 9 series for me

Blackvue. Clear crisp video (even at night), was pretty straightforward to hardwire, convenient to download footage, parking mode with built in volt limiter (can use an exterior one too), cloud storage capability and rear cam fits even with my rear curtain closing for my LS. Used mine for over 7 years, have in multiple cars as it's the favorite of all I've used. Worth even if it's just the UHD ones.
