So I just learned about this
BlackVue Power Magic Pro
It is a must have and it will work with ANY camera. The OTHER must have IMO is an Optima battery. This goes for any car and any driver (except race cars then I recommend Lithium). Yellow or Red top depending on how often you drive the car and if you ever run accessories off the battery only. Yellow top can handle being drained further without damage. I use the RED even though I often run the radio with the car off and have several devices that use standby power. The warranty is significant enough that if you ruin it from discharges that you can get a replacement or once the warranty is up you got your value out of it.
That said, if you drive the car daily for more than 30 minutes you should be good to go. These cameras don't suck down a ton of juice. Running a camera for an entire week off of a Optima Red top then driving the car for 30 minutes and then running it for another several days is likely within the realm of possibility. The batteries cost $150 (compact car) to $300 (V8 powered car). The Yellow is specifically designed to be drained almost completely and then charged back up at an extremely fast pace over and over and over by your alternator or high speed charger. IT HAS A 3 YEAR CAR AUDIO APPROVED WARRANTY!!! The Red Top is the better starting battery but it isn't rated as well for high current charging and deep cycles (using it all and then full high speed recharge). It also has a 3 Year Warranty but is barred from high current car audio use. Even if you buy a red top and ruin it from car audio they will only deny you if you either admit to it or are trying to replace multiple batteries at once. Even with the Yellow Top if you have multiple batteries that are over 1yr old they will require proof that you have a battery management system.
Bottom line... you can't get a better battery.
Running accessories with the car off? IMO the Optima battery and the BlackVue Power Magic are not optional! The BlackVue can run an unlimited number of accessories with an unlimited power draw through the use of relays. But without extra relays the device seems to be designed to handle 4 cameras without issue.
Ill be honest though you need to ensure these cameras are absolutely hidden if you want to get this guy.
My grandmothers section 8 neighbors keyed both of her and my grandpas cars 2x each because she had their car towed for parking in the her parking spot over and over and over even after being warned. I did my best to hide the camera but they saw it DAY ONE!!! They called the police about it and everything. The police laughed at them of course.
Anyways, I hope you can catch this guy!
Also it isn't necessary to have a parking mode capable camera. You can let the cameras roll non stop. Just make sure you get a 64GB card and set it too a resolution and fine setting that will get you how much time you need. 12HRs should be enough. You don't need to check the footage either. Just check the car for damage every 12HRs. If you find an affordable camera with auto sd card switching (the 0806 DOESN'T WORK) then you can run 2 64GB cards. If you got money pooring out of your ears you can run 128GB cards of course. Also just because a camera claims it can auto switch cards or that it has a parking mode do NOT trust that it actually functions without checking these forums first. I have a Mini 0806 and nearly every feature on it is busted. If you insert 2 cards or mess with almost any setting besides resolution it will start messing up, freezing, beeping, or not recording! All that said I have also used car DVRs that just take a camera input... Those are truly expensive, draw more power, but can be paired with a sony handycam that has a huge zeis lens and function night vision. Probably bit out of your reach money wise but then again I have no clue what you make or what you drive. You could be that millionaire that imported several Audio RS4s for all I know!
