What is video surveillance?
Video Surveillance has developed from time to time. Starting with simple Circuit Closed Television (CCTV) with analog technology and just recorded on video tape, Video Surveillance has moved to digital technology, which is requires some extra space on hard drive to store the data. Analog camera tubes were replaced with CCD (Charged Coupled Devices), and using this technology, a video can transmitted into digital and send accross the network. The data that has sent is encrypted so it is safe when it’s on the traffic. When it has reached the destination, the data can be decrypt and obtained by the authorize person. The DVR System is one step advance than the previous generation, that working as CCTV but save all the data in digital format. And lately, we also have IP-Based Video Surveillance that make possible to connect the surveillance camera to the network adapter or even the wireless one. Can you think the advantages of this IP-Based Video Surveillance?
How can the police use video surveillance?
The police can fight, prevent or reduce crime with the technology of video surveillance, making citizens, businesses and tourists feel safer. State-of-the-art wireless video surveillance systems (e.g. IP video cameras) and other new technology tools are used for deterring, detecting and investigating crime. They are installed on poles and building facades and activity is monitored around the clock in busy downtown areas such as central business districts, shopping malls, residential venues, downtown streets and tourist/entertainment venues.
Twenty to forty officers would be monitoring the videos. Videos must have outstanding image clarity as license plates need to be readable from 300 yards away and different camera angles must be viewable without time delays. Cameras must be able to zoom in and have night-vision. Cameras with automatic license plate recognition can also identify stolen cars.
