Although we may not think about it very often, closed-circuit tv(cctv) is a definite part of our daily lives. Much like Orwell’s “Big Brother,” cctv security is all around us. Once found mostly in banks, convenience stores and airports, cctv has spread to almost all public places, even our highways and schools.
Designed to provide surveillance on a “closed-circuit” security system, cctv differs from broadcast tv in that only the units directly linked can access the picture. With today’s Internet technology, the ponderous tv’s and access equipment of the past are now often replaced with Internet Protocol(IP) cameras that allow users to view the closed circuit picture from any internet connection. Technology improvement has also led to higher quality pictures including still-photography capabilities.
Modern public uses of cctv are as varied as the types of equipment available. Surveillance is the one we are probably most familiar with. We’ve all seen the familiar cameras in shopping malls, banks and other public places. Maybe we’ve even seen them on highway toll roads, bridges and stoplights and in patrol cars as tools for law enforcement. But cctv cameras also appear in less obvious places such as in manufacturing, the space program and other situations that would be dangerous or impossible for people to perform.
Because higher-end cctv security can be rather expensive, many individual uses of cctv are smaller scale, including such equipment as the infamous “nanny-cam” type surveillance that allows parents to check up on the daycare provider in their home and general home security that varies with the value of the property it is protecting.
The entertainment industry has also capitalized on cctv security equipment with a twist, using a closed-circuit type surveillance to produce a show that is broadcast to a wide audience. Productions such as “Big Brother” depend on security cameras to record the show’s footage. Crime shows and “candid camera” shows also depend on cctv camera technology to provide entertainment for its viewers.
How reliable and useable is cctv security? That is a question that Americans will continue to debate both on the street and in the courtroom as the technology becomes sharper and more pervasive. In the past, the often black and white fuzzy pictures of the lower-end systems could not provide any real evidence. Today’s systems can and do. Additionally, with all the concern about altered photographic images and unlimited public Internet access, the possibility of corruption exists with cctv footage as well.
How much cctv security do we want in our lives? Obviously we have a lot of it now. Does it really prevent and solve crime? Does it slow traffic down? Does it keep our homes and children safe? There seems to be some indication that cctv security does indeed accomplish many of its intended purposes including improving safety in workplaces and aiding in identification. And certainly, cctv security gives us a little peace of mind, something we can fall back on if something does happen to us that we need to view and analyze.
