Car break in deterrent

We are a team of two 15 year olds after we experienced two break ins that ruined our trips. After both me and my co founder experienced a break in, we realized that traditional security is just an illusion. We both had camera footage, we both showed it to the police, and they both dismissed it. We lost our entire trips worth of stuff, ruining our trip. Thats why we set out to solve this problem. Instead of making another passive recording device, we are making something that prevents thefts.
