A Brief History of CCTV plus New Advances
from: Maxx Home GuidesCCTV, or closed circuit television, has been around since the 1970s, first developed in the United Kingdom, where they were first widely used. Of course, as with most technologies, there's been many improvements since they first appeared. These major developments include easier installment, lower prices and easier configuration.
The main reasons these systems were developed include surveillance, traffic control, combating theft, shoplifting and employee theft, as well as robbery deterrence and identification.
There are several choicess in CCTV systems starting with black and white or color, which is one of the first decisions required when purchasing a system. Which one you choose depends mainly on what you're planning to use the system for.
In cases of robbery and theft prevention, identifying the suspect is critical, thus color helps immensely in these situations. However, if you're planning to use it for monitoring traffic or surveillance, black and white will do the job since it usually has better resolution and superior ability to pick up details such as license plate numbers during nightime surveillance.
You'll also have to choose between a wired or wireless system. Wireless has several advantages starting with easier installation. However, these systems are usually more expensive and less reliable then a wired system since a wireless system may encounter signal interruptions more often then with a hardwired system. Some research will help you decide which option is best for your needs.
Also consider in a CCTV system how large an area you want the camera to cover and the kind of light available in the area. This will help you choose the correct camera with the correct type of lens.
Currently there are some updates in the types of lenses used in CCTV systems. There's been several developments in the use of DVR technology which will effect the type of recorder you choose to use. Choices include time-lapse recorders, computer DVRs and stand-alone DVR systems. Time-lapse recorders are still being used, but the trend is towards DVDs and VCRs in general.
Time lapse recorders tend to be more cumbersome and difficult to install along with being less effective. Storing recorded tapes from this type of system can be a problem if there is a lack of space and the potential for damage. However, the advanced technology of the DVR makes it much easier to download to a computer or burn a CD, which is much more convenient.
Another aspect of newer technology incorporated into the DVR is the switcher and multiplexer functions built into it which means less equipment needs to be installed, making these systems more convenient. Prices continues to come down for these systems and so getting better quality has never been easier or cheaper.
Also, when considering a CCTV system, look at the different types of monitors. Where you're placing the CCTV will determine the size monitor you'll need. With so many advances in nano-technology, it's much easier to find smaller cameras with smaller everything, including monitors. Of course, with the more advanced technology of the internet you'll be able to use your computer monitor to view your CCTV recordings.
Currently, advances in CCTV systems are happening in the areas of storage, retrieval and video content analysis along with major improvements in the cameras used for CCTV including the smart camera that can actually track someone based on their behavior.
Transmission has also continued to advance CCTV systems with higher quality cables now available, including fiber optics. Continuing advances plus more use of DVR to record images has made CCTV a practical and affordable solution for home owners seeking a home security system.
