Homeowner setting up home security cameras nowadays in order to have a more secured and worry-free home is becoming a trend. For those that are not so familiar with this topic, it may seem complicated and too techie. Nevertheless, video surveillance is no longer that complex. It is just like one of those home entertainment systems that you’ve acquired. Below, you will know more about home surveillance system, their uses and how they came to be as well as their benefits and their basic components.
Video surveillance systems are used to record events at a specific location, relay the feed to a monitor, and record the feed on either videotape or a DVD. The live feed can be used to try to stop crime before it happens, or the recorded footage can be used to identity suspects. The first documented use of video surveillance was to observe and record launches of the V-2 rockets in 1942. The town of Olean, New York, was the first to implement closed-circuit television (CCTV) to try to reduce crime on their main street. Since that time CCTV systems have proliferated in many cities, businesses and homes to prevent and fight crime.
Currently, an ongoing debate exists concerning the effectiveness of security cameras at reducing crime. A four-year study conducted in San Francisco by the UC Center for Information Technology Research in the Interest of Society found that a security camera could reduce petty crime by up to 24%, but seemed to have little effect on violent crime. A similar study conducted in London, the city with more cameras than any other, revealed that the cameras are not as effective at deterring crime as most people would like to believe. However, the cameras can help authorities identify suspects or generate leads, as well as make many people feel safer.
A debate on whether or not security cameras are effective for slowing down crime rate has been going on for some time now. A four year study has been conducted at the UC Center for Information Technology Research in the Interest of Society in San Francisco and has confirmed that 24% of minor crimes have gone down. Violent and major crimes has not been affected that much though. In London, a similar study was also conducted and has shown that security cameras are not very effective tools, as believed by the majority, when it comes to crime prevention. Although this has been proven by many researchers in the past, nobody can deny the fact that security cameras are very useful in tracking down such criminal acts and help identify lawbreakers.The components of a home surveillance system are primarily composed of a security camera, transmission, device, monitor and a recording device. The various parts of a surveillance device can be modified to create a simple surveillance system or a complex one. They can be used indoor or outdoor with an array of lenses designed for different functions.
The lenses are recognized by their field of view and focal length. The focal length determines how clear and object is at a distance while the field of view can be determined by the actual size of the location. Not all regular security cameras are fixed to have pan, tilt and zoom features similar to ordinary cameras.The camera feeds are transferred through coaxial cables, fiber optics or a network connection. Coaxial cables are designed for short distances whereas fiber optics and network connections are for maximum range.
Monitors are created for video signals acceptance only and are usually 17″ and 52″ big. Through these monitors, users can view multiple cameras on a single screen or cycle between various camera feeds. The recording device is the last component of a video surveillance system. The most recommended choice is the digital video recorders for the reason that they can acquire and record footage at a superior resolution and they make it easy finding a particular footage.
Find the right security cameras for your security camera needs. They can help in the protection of your household or organization with little to no cost to you. Latest reports often show that security cameras greatly reduce crime levels.
