CCTV surveillance systems play an important role in fighting and preventing local and international crime. These closed circuit television systems were in place in London before the July 7th bombings and this footage is being used to identify suspects and investigate the attacks.
Besides fighting terrorism, CCTV security systems installed in public places or retail markets can deter crime, provide the police with leads, help citizens feel safer, and improve the economy of a crime-stricken area. Most CCTV systems have now gone digital for improved performance, urveillance camera maneuverability, and quicker feedback as compared to analog systems.
Implementing CCTV systems
Law enforcement or security professionals best support CCTV systems. These teams of rofessionals need to monitor the CCTV video evidence on a timely basis and they need to be properly trained in order to interpret suspicious behavior caught on the system. When all of these factors are in place, then the CCTV security system will be effective for keeping citizens and shoppers safe. In the case of some municipalities or businesses not being able to afford all of the necessary components of a CCTV system, many CCTV providers can recommend a scalable approach so that priority security needs may be addressed first. Then, additional surveillance cameras can be purchased in ucceeding years as the budget allows.
Digital CCTV systems and surveillance cameras
A modern digital CCTV security system consists of hardware and software components that collect and transmit vital surveillance camera information over fiber optic lines to control rooms staffed by security professionals and equipped with digital CCTV monitors. An example of the surveillance cameras used for reducing crime in LA's MacArthur Park include CyberDome DayNite 25X cameras equipped with removable infrared cut filters, 25x optical zoom lenses, 12x digital zoom capabilities, and 360-degree PTZ (pan tilt zoom) capabilities. This MacArthur Park system also includes GE Storesafe DVRs (digital video recorders) and GE KTD-405 keypad controllers. DVRs are capable of saving CCTV data to a PC for up to ten weeks of recording and some even feature motion etection technology, which means that the footage is only recorded when motion triggers the DVR system. Digital surveillance cameras range in type from compact, fixed cameras to direction-controlled models that can see in the dark under various lighting conditions. CCTV decision-makers need to know what kind of job each surveillance camera must fulfill. Will it watch the flow of passerbys (fixed cameras) or will it need to monitor a crime-targeted area (dome cameras with PTZ functions)? These video security managers also need to consider weatherproofing their surveillance cameras if the cameras are mounted in an especially hot or cold climate, or if the viewing fields could be obscured by dirt or dust.
What kind of crimes do CCTV systems prevent?
Evidence has shown that CCTV systems mostly deter property crimes and robberies, but not more violent crimes such as rape and aggravated assault. CCTV systems may not catch these crimes because they may occur away from the surveillance cameras in more deserted areas.
Fortunately in most situations, when a CCTV system is in place, criminals generally shy away from these monitored areas fearing prosecution since these recorded images can be used in court. As noted previously, in order for a CCTV system to be effective, the electronic system must be used in conjunction with human know-how and skills and it should be carefully integrated into existing security plans.
CCTV: Looking ahead
In the next few years, digital CCTV systems will evolve into wireless CCTV systems that employ GSM (global system for mobile communication) or 3G (third generation) onnections. These wireless systems are completely portable and can deliver live images to a PC, an Internet phone, or a laptop. The cameras are tiny, but include many of the sophisticated features of full size digital CCTV cameras. CCTV customers are also seeking IP-based solutions with LAN/WAN delivery options despite some lags in the technology's image quality and frame rate. "Make no mistake about it, the future is wireless," says Thomas M. Wade, president of Samsung CCTV. "We'll be pushing crime-related images to police cars in the future. Imagine an abduction or robbery in which the responding units are seeing the video and the suspects as they are rolling to the scene. It's all possible and it is the general direction of the industry."
There is also talk of linking CCTV cameras together to form a worldwide network to prevent terrorism, but this international surveillance system would cost billions of dollars and would require extensive international cooperation.

Night vision security camera offers home and office protection
The hours we keep don’t always correlate with daylight hours. We find ourselves working after dark in order to get everything accomplished, at home or at work. Next time you find yourself out late, wouldn’t you feel safer knowing your office or home was equipped with a night vision security camera? A night vision security camera provides clear images no matter what kind of lighting conditions it’s placed in.
You can use a night vision security camera in any darkened area, such as a garage. How many times have your kids left the garage opened all day? Usually that’s harmless, but on occasion small animals or neighborhood pets can crawl into the garage. With a night vision camera, you can check out these darkened spaces and eliminate any unwanted surprises.
Easy to install and adapts to a variety of applications
A simple wireless system takes hardly any time at all to install. All you have to do is pick the proper angle of surveillance and plug the camera into the receiver, which then transmits a feed to your television or computer, depending on the camera you purchase and your personal preference. In less time than it takes to make a microwave dinner, you can set up a night vision security camera in your home or office.
There are different kinds of night vision camera because we all have different security needs. Think for a moment about what kind of security suits you best. Some cameras capture color images during the day and black and white images at night. Another kind of night vision security camera, such as the Low-Light Wireless NightWatch Camera from X10, captures only b/w images, which makes it ideal for any darkened area.
A night vision security camera pays back peace of mind
You may be asking yourself if a night vision security camera is worth the cost. The answer is a resounding “Yes!” You can purchase a wireless camera system that you use every day for a year for a cost that equals just a few dollars a week, if that. That’s right -- just a few dollars a week. For the price of a magazine or a latte per week, you, your fellow coworkers, and/or your family can relax in knowing that all activity in any poorly lit area is being monitored.
Cost-effective, easy to install, and able to capture images indoors or out and in all kinds weather -- what are you waiting for? Now is the time to consider purchasing your night vision security camera. Protect your home or office today.
