M550 3CH

Viofo isn't actually bad, it is possible you got a dud because I'm still on the same one for 5 years. Another good option is AZDOME M550

I have the Azdome M550 Max for my xc90, and it works amazing! Don't know much about technical details, but I bought an extra product from them that enables 24/7 recording even when the car is turned off using extreme low voltage current from the battery. If you're not good at wiring management or know electrical engineering kinda stuff, get the wiring done by a local shop and they'll do it for minimal charges. It definitely helped me to identify on my Honda who scratched it at night because we have to park in public spaces and turns out it was a kid riding a bike too close to my other car. Works for all Volvos though. The whole camera set https://a.co/d/enRhgq8 The leads that enable 24/7 recording https://a.co/d/fC4joEm

I upgraded my battery to a 48 AGM from interstate and I’ve ran my AZDOME M550 Dashcam outside for a week before starting it and it started right up. My old Mazda battery had no issues either but I kept it on a trickle charger every night (since I normally park in my garage).

If you’re leaving your car over winter then I’d get a trickle charger or prematurely replace the battery, these new 35 group Mazda batteries SUCK. The M550 has a parking mode that uses very low battery when the cars off aswell so, options

Got an AZDOME M580 in my fusion and put an M550 in my s550. Works well, tucked up behind the rear view, plugged into OBDII port.
