CCTV

CCTVs are being used in the US from the 60s and are not a new phenomenon. In the 60s CCTVs had low resolution and were black and white. These cameras were connected to black and white monitors. However, today CCTVs are more advanced than basic cameras. They are extensively used in railway stations, sports stadiums, shops, stores, parking lots, garages and parks.

Earlier CCTVs allowed the viewer to switch between cameras and watch only one camera at a time. Whereas present day CCTV allows the viewer to watch multiple cameras at the same time without the hassle of switching from one camera to another. The other advantage of modern day CCTV is recording through a computer using Digital Video Recording. Now one does not have to rely on video tapes as it was done in the 70s and 80s. Digital Video Recorders are automatic and does not rely on human intervention of changing tapes. These recorders are also well equipped to record audio sounds without any problems.

In todays world a CCTV can be operated from a remote control center and ensures high quality digital image and sound that can be streamed anywhere. These CCTVs can pan in, zoom or tilt making it easier to capture images. There is two way audio system where the operator can transmit his voice as well as listen. One can record, search and replay audio and video using modern CCTV technology. Many CCTV are equipped with night vision.

Since the 60s CCTV has come a long way and there is still scope to further develop this technology so meet the ever changing needs of the consumer. Companies are striving hard to ensure that CCTV is capable of giving the surveillance market what it needs.
