One could go through a history of criminal or scandalous activities which have taken place in offices one would find how easily the cases were cracked where on-camera records of the activities were available and how far-fetched its investigations became just for the lack of photographic record.
Huge establishments such as departmental stores are easy targets for large-scale pilferage. Digital coding has helped ensure that no visitor to the store left with stuff he has not paid for. The technique activates alarms whenever there is attempt, deliberate or unconscious, to walk out of the premise with an item without paying for it. Yet, smart thieves find a way out, so it is ultimately the camera system that helps well.
The monitors keep displaying every move made by visitors or the employees. This would be checking any dubious, suspicious or hazardous activity right away. Besides, it is not just a threat impending from humans. Sometimes there are other factors also, which could spell disaster and which gets detected timely. Thanks to the placement of security cameras at vantage points.
This is true that these cameras may not have replaced the utility of other security devices such as metal/narcotics/explosive detectors or even sniffer dogs, but they surely facilitate by pointing out any unusual activity and proves to be very beneficial in rendering the incriminating evidence at the time of investigation or presenting a case in a court of law.
Office security systems often use spy cams that go undetected by those working within the premises and these help keep an eye not only on the outsiders but even those on the premise grounds throughout and monitor them against any irresponsible, damaging or immoral activity during duty hours, also safeguarding thereby the decorum of the place of work.
