Hard wired connection for dash cam

[Happy Ant]

Seat Leon ST FR 2025 model, I have recently purchased a Vantrue S1 pro max dashcam front and rear and hardwired it into the fuse box but I constantly get this tap tap or knock knock noise that i thought was coming from the camera, however I took the camera off its mount and disconnected the power to the base unit and the noise continued. I am guessing I have connected it to a wrong fuse or earthed wrong place. Does anybody know the correct fuse to wire into in order that I can have the parked mode operating overnight please?

But is it not how you routed the cable.
Because even if you pick other fuse that does not matter for the noise. That will be still the same.
For any dashcam you plug in a fuse extender. In one you put original fuse for the car and other you place fuse for the dashcam.
This cant deliver any noise.

Only when you plug it in constant 12v power it can drain battery when standing still.

SO what is causing the noise?
Could it be a bad earth connection?
Or is there some sort of interference between the cabling of the dashcam and the cars electrical systems?
This noise only started after the installation of the dashcam
