Is this possible to setup without physically accessing the bear like sending it overseas while I’m away for work? Or would I need physical access to the bear in order to complete setup?

Thanks for reaching out with your question! The bear camera comes available in two options. For remote access as you describe you would need to select the Mobile version. Once the bear has active service and the bear itself is turned on, you will be able to remotely access the live feed and camera set up as long as the device remains on.

How much heavier is the teddy bear than an actual teddy bear with no hidden camera? Also if a person hugs or squeezes the teddy bear a bit can they feel the recording equipment inside? Thank you

As with any camera, it is possible that detection can be achieved by someone handling the item, in this case the toy. The doll camera is cetainly a bit heavier than one with no camera . Most people that have used this item provided good feedback of utility and form. 

My kid is playing with this teddy bear nanny cam, what do i do

Let him/her play with it or procure another toy!

Hi there, i would like to order your stuffed tedy bear because i do think, that my little child is being molested in the preschool. Do you think that when someone grabs your teddy bear he could potentionaly recognize, that there is hidden hardware inside of your teddy bear? Do you ship overseas as well? Im from Slovakia, Europe many thanks

So sorry to hear about your situation. We do ship to international locations. 
The bear camera is pretty well disguised. There is no fool proof system that would prevent a determined seeker to find the camera but it does do very well at keeping things hidden and there is no obvious design feature that would be easily pointed out.

Does camera work without wifi

Yes. the bear camera can work without wifi. Keep in mind that without wifi you will not be able to access the camera remotely and motion activation requires wifi. In other words, without wifi you can record continuosly and review after the bear returns to you.
