I have the BlackVue DR900x plus. There are newer models 970x. I have the came paired with 3 battery packs hardwired to the interior fuse box for rapid charging. They keep the cam powered for 55+ hours when parked (most important part for me). Also got an old t-mobile portable hotspot (cool pad) added 2G/$10/per month plan. More than enough when going out for work shopping etc. At home the can connect home WiFi and records until battery dies. Happy so far.
when you say interior are you thinking of NOT having a rear cam? I assume you do not in which case you need a 3-cam system. Blackvue has the best low-profile that I know of but I had issues with their lousy/unresponsive support so had to go with one that has a screen. ended up with a 2-cam viofo and it’s a lot lower profile than I anticipated…fits pretty well behind my 2014 Accord mirror. you can turn the screen off completely and use the app - which is what I do since the screen is tucked up behind the mirror (the screen can be turned off/on by voice command which is nice). but yes…you need 3-cam which will run you a bit more!
I've had a Blackvue DR900X 2-channel (front and rear) for years. Had it hardwired into my M235i, pulled it out when I traded that in for my i4, and have been using it in the i4 for almost 3 years. I haven't hardwired it in to the i4 because I've been super lazy so I've only been using the front camera, and the 12v outlet. Whatever I get when this lease ends in May next year will get it hardwired in front and rear again. The picture quality is great, and although I used to really hate the app, they have made improvements recently that have made it better. I've also heard great things about Viofo dashcams, but have never used one.
I have a blackvue. Works great
The DR900X. Had it on my previous vehicle. Was a little bit of a PIA to fish the cable down the a pillar but once I got to where the wiring harness runs along the bottom of the jam, it was pretty easy to fish it all the way to the back to hook up the rear cam.
Dongar mirror adapter makes it cake, I just went with the garmin 67w, works great. Did a blackvue DR900x in the wife’s car and it’s great! For the price difference and easy install I’m happy with the garmin.
Blackvue 900x front and rear. I love it. It cost about 600 maybe a bit more because I got a custom mount to hang on my rear view mirror. A battery for continued recording, storage micro sd card, and extra stickies for the wiring but that's about it. I installed it all myself and looks amazing. I am looking to upgrade to the latest blackvue cams.
