Living in the world,where nothing is certain, security is probably something you must not compromise on. Who needs security? There is a misconception in the society that security is only required by the rich people because they have a lot of wealth to protect. This is wrong, no matter if you have anything at home or not, you still need security because offenders can cause you other kind of harm also.
No matter if you are rich or a middle class, you still need security. Not having any security measure make your home or office more vulnerable and there are more chances that invaders get into your home or office.
