The type of security used is important because you don’t want an employee accidentally triggering the alarm or you don’t want to leave burglars get away with anything, it all depends on what you are doing and where it is. The location is the most important thing because you don’t want a camera or motion detector facing the wall and where it is in general. if the security is used personally or in a house hold motion detectors are the best for when you’re out and about and no one will be home, however in a work place cameras are the best for busy environment’s. security needs to be in the right place for them to work properly.
