I think all mechanical security systems no matter how good they are or what insurance criteria they meet, they are more of a visual and nuisance deterrent than preventive. If a thief wants it bad enough they will find away. The emphasis is on the owner to make it as difficult as possible so they just move on. Unfortunately, onto their next victim. Cameras are very good as we have these at home, we will eventually install cameras at this property. But correct me if I am wrong, camera systems rely on power the internet or recording equipment to be successful. I know you can buy dummy camera's.
