A510

That's a very good price for the stuff that you get. I have the same one but I got it for around 14-15k. Works very well!

This is the best one. Although it has lithium ion battery. But many are using it with no issues.

Qubo has super capacitor. Lithium ion tends to get hotter. But 70 Mai 510 many are using in India. So no issues with that.

It’s likely that the dashcam provided by Hyundai does not have Sony starvis 2 sensor. 70mai A510, A810 etc all have it. It makes a huge difference in clarity, especially at night time. I’d get it from outside.  Passenger electric seats and driver memory are very nice, though. Wireless CarPlay is through an adapter, so one of your usb ports will be blocked. 

Congratulations!! For your question: It depends. If you're okay with a "plug into USB" to use one , get the 70mai 510 or above. (Dual channel). Ask the SC if they can install it in hardwired mode. If you want a hardwired one for parking mode, Hyundai has their in-house offering : Hyundai Mobis MH7 dashcam. It gets the job done , but is expensive for what it offers.

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.

Cabin cam is good to have, starvis2 is a must have. Go with A510 70mai.

Got a 70mai a510 with front and rear for my mum. Quite good that I bought another for myself. AliExpress
