Despite of the debate on the use of hidden cameras against surveillance and privacy, we should take a look on the advantages of hidden cameras in the housing environment.
Hidden cameras around your house is to prevent people from stealing from you, well it wouldn’t actually prevent people from stealing but it would allow you to find out if people have been stealing from you. By placing a hidden camera in an object near an area where there is money you will be able to tell if somebody is taking any kind of money and then you can later confront this person and get the stealing to stop.
Hidden cameras are actually really useful to have around the house if you think that something is wrong, whether it is your nanny, your children or the suspicion of stealing the hidden camera will catch that person in the act and then give you undeniable proof to confront that person with.
The first CCTV cameras used in public spaces were crude, conspicuous, low definition black and white systems without the ability to zoom or pan. Modern CCTV cameras use small high definition color cameras that can not only focus to resolve minute detail, but by linking the control of the cameras to a computer, objects can be tracked semi-automatically. For example, they can track movement across a scene where there should be no movement, or they can lock onto a single object in a busy environment and follow it. Being computerized, this tracking process can also work between cameras.
CCTV critics see the most disturbing extension to this technology as the recognition of faces from high-definition CCTV images. The combination of CCTV and facial recognition has been tried as a form of mass surveillance, but has been ineffective because of the low discriminating power of facial recognition technology and the very high number of false positives generated. This type of system has been proposed to compare faces at airports and seaports with those of suspected terrorists or other undesirable entrants.
Taking video camera without people’s knowledge called as hidden camera. Closed Circuit Television or CCTV is known as one type of hidden camera. Closed Circuit Television is the use of video cameras to transmit signal to a specific, limited set of monitors. CCTV is often used for surveillance in areas that need monitoring such as banks, casinos, airports, military installations and convenience stores.
Increasing use of CCTV in public places has caused debate over public surveillance versus privacy. In industrial plants, CCTV equipment may be used to observe parts of a process that are remote from a control room, or where the environment is not comfortable for humans. CCTV systems may operate continuously or only as required to monitor a particular event.
The most measurable effect of CCTV is not on rime prevention, but on detection and prosecution. Several notable murder cases have been solved with the use of CCTV evidence, notably the James Bulger case, and catching David Copeland, the Soho nail bomber. The use of CCTV tot rack the movements of missing children are now routinely.
