Looking into 2 channel dash cams for all of my vehicles after Two accident within a year my wife got into but wasn't her fault and got screwed on both of them because of no witnesses. Neither had insurance anyways but........
I don't mind putting down the cash as long as it's good quality.
Ive been researching them but most seem to have issues plagued by either heat build up in the car in the summer and/or failure to operate due to memory card formatting.
Glad I do everything in my power to stay within the law and pay stupid amounts of money to stay insured but others don't have to with no repercussions.
Got to love it.
If you mean it when you say you don't mind putting down the cash, get a BlackVue camera. My personal recommendation is the DR750S. I run it in my car and can assure you, you're getting quality. I have the 2 channel system and it works wonders. I'll post some documentation below.
Forum discussion thread (There's a bit of technical debate within the thread about the framerate and filesizes of the new DR750S but that's mostly a deciding factor for people upgrading from the DR650S. A lot of firmware updates have improved the camera.)

One of BlackVue's main selling points is "True Parking Mode" which can be achieved when you pair it with something like a PowerMagic Pro (See my tutorial
here if interested).. It runs optional constant power to the camera and when the car is stationary for 5 minutes or more (Activated by the internal GPS within the camera) it will begin motion detection capture or impact capture based on your sensitivity settings. This ideally would be your best bet for recording when parking. Any dashcam that has a battery capable of allowing the camera to record for a couple of hours or more isn't going to last. The BlackVue camera has a super capacitor which is superior to a battery in terms of recharge capability and temperature resistance. The super capacitor lasts just long enough to safely power down the camera to avoid corruption. Your battery power for long parking sessions comes from your car battery. The PowerMagic Pro unit handles the voltage requirements and will shut down the camera if your car battery gets too low to avoid ruining it.
Night view was definitely a concern for me, and BlackVue seems to have handled it fairly well while maintaining quality. Here's some screenshots below I took from my recorded footage.
FRONT CAMERA: Left shot is without night vision enabled in camera settings, right shot is with night vision enabled.
REAR CAMERA: Left shot without night vision, right shot is with night vision.
You can see they don't make too much of a difference in very low night conditions (The light is coming from a single street lamp). There's also general brightness settings for the recorded video which help a lot regardless of night vision being on or not. The mobile app is full of all of these settings and a lot more. The App is the main communication point with the camera for settings and viewing footage (Also live viewing the camera to allow for positioning when mounting).
