These Camera Surveillance Systems And Digital Video Recorders captures video clips of events for your record. These can be played back to look for possible evidence of crime, or can be monitored online by security people. These also help to improve PRODUCTIVITY of employees. This is achieved by doing "remote surveillance" by superiors.
These are useful in offices, factories, shops, banks, malls, cash counters, open premises of buildings, colleges, parking lots, etc.
Cameras are installed at appropriate locations so that they can "see" the activity in areas, which are to be monitored. Some cameras are hidden or camouflaged, whereas some are installed openly so that people know that the area is under camera surveillance. This helps to reduce pilferage in departmental stores.
The DVR keeps a record of video as seen by the cameras installed in appropriate locations. Record of pilferages in shopping malls, un-necessary fuss created by some nasty customers, etc is useful legal evidence. With the "eyes" of the camera recording their activity, workers do not while away their time and increase their productivity.
Day/Night Cameras have Intra-Red (IR) LEDs which emit infra-red light and the cameras can see even at night. Cameras can be mounted on stands, which can rotate, pan, tilt, zoom.
