DR900S-2CH

This was my 3rd Blackvue and my 900S Dual Channel from 2020 just kicked the bucket. Same as OP my rear camera will no longer be seen my Dashcam. I think I am saying "Adios" to Blackvue and going to look for something better or at least more reliable.

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.

RedTiger from Amazon Doesn’t have the blackvue price tag and runs fine so far after 8 months on the missus’ car. Mind you my blackvue 900S on my car is still working great after 4 years.

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
