Okk so I was in the same situation about 2 months ago.
And I found out that even though qubo has a super capacitor it just turns off when overheated ( you can find some videos in YouTube as well) and then I finally chose a510 because of the better video quality and I personally like its small size look. Also for your case where you need to park your car for months in direct sunlight, the a510 can be easily dismounted from its bracket.
Also one more advice if you are planning to buy from Flipkart they will provide you free installation. Please don’t take that and get it installed by some reputed accessory shop. (They actually damaged the power cable during installation which resulted in my camera getting shut down randomly).
I use 70mai A510, it has great quality videos and never failed to impress. Although it has 4G sim compatibility but I never used it. Installed it with dongle attached to power dimming mirror so no hassling with cables.
If you want to use dashcam for parking monitoring also i.e. it will need hardwiring better go for official dashcam to avoid issue with warranty. If that's not the case you can go for any dashcam. Just use the 12V port or USB port to power it like any other accessory. I use 70mai a510 which is good.
I use the A510 and it works well for me. The supercapacitor aspect is valid, but unless you are driving constantly in highways and its exposed directly to the suns heat, its ok.
