The need for security in government buildings is something that most citizens won't argue with. But while police officers may guard a courthouse, some people may wonder why it is that buildings such as a post office need to have security cameras. The answer is obvious: a post office is a potential target for criminals just as surely as any other government building is,.

Interior

Most post offices have some security cameras inside the building. Those cameras watch transactions, the lobby, and who uses the post office boxes. They are the cameras that people traditionally think of when they think of security cameras.

Exterior

Some post offices also have exterior security cameras to monitor the outside of the building, including the side and main entrances and perhaps even parking lots. Many of those cameras swivel to watch larger paths of entry, and they may view other nearby buildings as well.

Deterrence

The primary purpose of having security cameras in and around a post office building is deterrence. Post offices have been the victims of robberies and violent crimes in the past. If criminals or would-be criminals know there are cameras in the building, then they may avoid targeting a post office.

Accountability

Many of the security measures that are taken with cameras are directed at postal employees as well as outside threats. Having security cameras focus on the employees, especially those who handle money and packages, will help ensure honesty and accountability from the post office in case there are unexplained losses.

24 Hours

Because security cameras can function at all times, the post office is observed 24 hours at a time. That provides round the clock protection, and if something does happen the cameras will be instrumental in discovering who committed the crime.
