Anti- Theft Help

Hey Guys,

So Im in a bit of an odd situation here. I park my truck outfront of my home, which is in somewhat a nice neighborhood. BUT over the past 3 months my truck has been "broken into" twice...

Here is the situation.

I know I lock my doors every time I leave my truck - I double check since the first break in happened. Also, my truck seams to automatically Lock after about a min to 30 seconds after I press unlock or Leave the Vehicle.
I checked the windows and they are all fully up and there is no signs of forced entry that I can see - I have No clue how they Got in

My question is, does anyone have any safety devices, such as a "nanny cam" hidden somewhere in their vehicle? Or any other suggestions on how I can prevent this from happening again? Both times I have come back and the inside has all my stuff thrown everywhere (really a pain in the ass to clean up), all parking change stolen (like 5 bucks at most) and this time my iPad was stolen (it was hidden). I usually dont have anything of value in the truck since the first time this happened, but I do worry as someone has been getting into my vehicle and going through all my stuff, which really is upsetting.

Any Ideas / suggestions are greatly appreciated. We have considered installing a security camera outside our house to face the street where I park.

Thanks TW!

 

Get an aftermarket car alarm and that security bar someone on here makes for the rear window.
