i need a anti-thief product.When i go out,it can send an SMS (GSM network) when the door is opened (it can be a thief!),or transfer videos with 3G.

anybody who can give me some link for that product?

 

I think that is the wrong forum. Try off-topic (even though, I have my doubts if it will be accepted there). This forum refers to knowledge resources and not to electronic products and resources of that kind.

Better: wait for an administrator to move it.

 

I've moved this to the General Electronics Chat forum, where it is more likely to draw useful response.

A quick Google search shows many types of SMS capable security systems. Can you be more specific with your requirements?
