It might be worth looking into a dash cam that can be wired. If you have a homelink mirror, you can wire it into the mirror for a constant draw, which would allow you to power the cam 24/7 and let you use the motion detection and parking modes (if your cam has those features). Or, if you don't have a homelink mirror, you can wire it into the cabin fuse box.
I bought my front and rear dashcam setup (Viofo A129 Duo) for $130 USD on eBay, and then bought an Invisicord to wire into the homelink mirror for $25 USD. Currently using an older 32gb card but I'll be upgrading to a 128gb soon. For less than $200 I have 1080p quality with 30fps video on both front and rear with motion detection and a parking (time-lapse) mode. It's already paid for itself by catching an attempted moving hit and run.
