How can I attach a camera to the headliner?

I have a back up cam that I would like to use as a baby cam pointed at my baby seat in the back row middle. The camera can be mounted anywhere via two screws or double sided tape. Is there some kind of special Velcro or screw that I could use to attach it to my headliner? Pics below.

From rovrlab...Get without any lamp, then get whatever lamp you choose and attach camera also.

 

Double sided tape and stick it to the back window.

 

Can't - just got the back window tinted..

 

With that are they adding a new lamp fixture or does this replace the existing one? I need the camera to point from the back of the truck towards the front. Baby seat is situated backwards, so the baby is looking out back window.

 

Suction cups maybe? Not sure if they will damage the tint, but they are much kinder than double sided tape.

 

Alien Tape. Stands up well if you leave it alone, but twist the object 45 degrees and the Alien Tape lets go.

 

Yes, it's meant as a replacement lamp.
How about the coat hanger location at rear window?
