A surveillance camera reduces crime greatly. An armed robber would rather go elsewhere than have video evidence linking him to the scene. When casing a potential crime scene, a criminal will often look directly at the camera. A review of taped crimes will often show the criminal was in the premises before he came back to commit the crime. Fast food and convenience stores are a primary target of armed robbery.
Banks only account for one out of two hundred and fifty armed robberies.
The primary choice businesses make for reducing armed robbery risk is to install video recording and monitoring systems that use today's technology for image recording.
