Highly recommend something that has an additional rear-facing camera and does not run on battery (hard wired to your car). Warmer climates kill the batteries and make some dashcams become useless.
One of the more popular ones i've seen. Keep in mind $250 is a small price to pay if you ever get into an accident compared to if you have no solid evidence of the accident and the insurance company decides to nail you.
take a look at the sidebar, there are approximate prices listed next to each camera
i've gifted a viofo a129 pro duo in the past with success and would recommend it as it's right at your budget (although on the top end)
my screen on amazon shows a $50 coupon to clip to bring the price down some plus add the hardwire kit, an sd card, and an add-a-fuse (mini or low profile size depending on what's in her car) should bring you right to $250 after taxes
VIOFO A129 Pro Duo is the way to go IMO. Great performance, stays out of the way, comes with multiple 3M pieces so you can reattach the camera to the window.
Sorry I don't have any footage on hand that I would post online.
FYI looks like Viofo released an updated version of the A129. Now it's the A129 Pro Duo, and it's 4k in the front cam. Looks really nice.
Just had my camera installed yesterday, Viofo A129 Duo Pro with the HK3 Hardwire Kit. I did quite a bit of research and for the price I don't think you'll find better. I had a shop professionally install it which cost $140 (I think that's high but it's a local place that was having some issues with the landlord/permits so I understand). Viofo also seems to release regular firmware updates and I had it up and running (with the app) in a few minutes.

But for the extra $90 I would get the first one I posted; you can make out a lot more with the 4k camera (i.e., I can go frame by frame and make out license plates).

Front and back on mine...great model
Super happy with my Viofo A129 Pro Duo.
If you have a frameless mirror, I highly recommend this Dongar adapter for switched power, unless you also need constant power for parking mode.
