Retail stores are places where shoplifters are most active. Research suggests that retail stores lose items to theft and negligence on an everyday basis, cumulatively adding up to a significant loss of money over time. That’s why it is necessary to have surveillance cameras fitted within and outside retail stores. Not only does it prevent theft, but constant observation also prevents anti-social elements from harassing people. This is true especially in large retail stores that have many floors, many parts of which are potentially not covered by human security or guards.
