Dashcam hardwire issues

First time poster here. Anyone mind taking a look at my setup to see if I did this Vantrue dashcam hardwire for my 2020 Kia Telluride wrong?

I did this 12 days ago, and didn't have any issues until a few days ago. After letting the Kia sit for 14ish hours, the battery was dead. Which is weird because about a week ago, it sat upwards of 19 hours and had no issue. After Jumping it and driving around for an hour, I let it sit overnight. I have my dashcam settings in parking mode set to impact only, and made sure not to touch the car to get a good baseline. After 14 hours, my battery was sitting at 12.14V. After 22 hours, I couldn't get a good reading (operator error) but the car struggled to turn over.

I have my battery protection switch set to kill the dashcam at 12V so I am not sure why it is still dropping below. I would assume I either wired it wrong, or the battery is just on its way out. But that would be a hell of a coincidence since I wired it 12 days ago and have had no issue for the past 2 years. I did buy it used, so if it was a factory battery then it would make sense it is just old... but again, it would be a hell of a coincidence.

I have since unplugged the dash cam and will monitor the battery to see if it drops more on it's own, but unfortunately can only let is sit for 12ish hours at a time for the near future before it needs to be driven. Regardless, I will get the battery tested in the next few days.

I tapped my battery (red) cable into the fuse for the sunroof (20A fuse on the right) that was always hot on the right side of the fuse slot.

I tapped my auxiliary (yellow) cable into a spare slot (fuse on the left). I verified I was pulling no amps with the car off, and 12 amps with the car on. With power coming from the left side of the fuse slot. To reiterate, I had the flip the fuse tap so the slot furthest from the cable was the slot I was pulling power from.

Anyone see any issue with this setup? Any feedback would be greatly appreciated!

I'm unsure about the Kia Telly. I do know that many an aftermarket thingy (customer DiY) will very often create a parasitic draw onto the battery. Most usually because the installed thingy keeps the circuit awake. (BMW term for not going into complete shutdown) I would try to perhaps install both leads into a "switched" (turns off with vehicle exit) circuits.

Keep us abreast of your battery monitoring.
