CCTV Camera Surveillance Systems:
CCTV systems 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 acheived by doing "remote surveillance" by superiors over internet.
These are useful in offices, factories, shops, banks, malls, cash counters, open premises of buildings, colleges, parking lots, etc.
CCTV 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 CCTV Cameras have Intra-Red (IR) LEDs which emit infra-red light and the cameras can see even at night. CCTV Cameras can be mounted on stands, which can rotate, pan, tilt, zoom.
We can see the video picture captured by the CCTV camera on a TV or Computer screen. It can also be recorded on a hard disk using a Digital Video Recorder (DVR). With a networkable DVR, which can be connected to the internet, one can monitor the cameras remotely from another location.
