Security camera systems play a key role in many aspects of life. Businesses are forced to deal with inventory losses either due to pilferage or theft by shoplifters. Quite frequently, land and homeowners deal with theft. Though they all try their best to curtail this criminal activity, they’re often unsuccessful in their attempts. Security camera systems provide a great deal of help in preventing a number of unlawful acts and have contributed towards redefining not only home security, but security at businesses and workplaces. Security cameras that come with a wide range of features and options are available on the marketplace today and can be made use of in different locations and areas for a variety of purposes. The developments that have taken place in the surveillance systems industry in the recent times have served to raise security management capability a notch higher. These developments have also been instrumental in beefing up monitoring and enforcement of law and curtailing acts of crime.

As far as security camera systems are concerned, there are basically two types: Closed Circuit Television (CCTV) and Network Video Recorder (NVR). The former type is the video surveillance camera system that is most commonly used by most people. These systems that make use of analog cables and D1 recording are connected to DVR devices for the purpose of recording videos. They are very cost-effective. On the other hand, the video quality of systems that use NVR cameras are much higher and they produce better images (resolution 1080p) compared to that generated by CCTV cameras. The Network Video Recorders make use of Ethernet cables that are capable of capturing as many as 2,000 frames per second. Additionally, it is possible to connect NVR camera systems to a network, router, personal computer or switch.

If you are planning to purchase a surveillance camera system, there are a number of factors that you need to keep in mind. The most important factor is the TV lines in the image produced by the surveillance camera. This gives you an idea of the picture resolution. The more TV lines the camera has, the better the resolution. Whereas the resolution of a standard camera is about 350 to 380 lines, the better cameras will have 400 to 500 lines.

Another aspect that you need to consider is the image sensor. This device converts optical images into electrical signals. Many security cameras make use of charge coupled device (CCD) image sensors. Most customers look for cameras that are capable of converting analog videos into digital information for better quality videos.

Security cameras are of paramount help in preventing theft as well as other illegal activities. This is one of the key reasons as to why camera systems are installed. They curb robbers, criminals and petty thieves. Security cameras are installed at specific points around apartment buildings, bungalows, townhouses, schools, malls, offices, and several other private and public places. Big businesses employ staff members to monitor surveillance camera images and report if they detect any criminal activities.

The new generation camera systems and the extended central command systems used for surveillance purposes come with audio recording capability. The camera systems themselves store the audio recordings and can be presented as proof when fighting legal cases, such as a case of sexual harassment. Video records of employees engaged in pilfering inventory or other criminal activities can be presented in court as evidence if they deny their charges or file counter lawsuits.

Security camera systems can be put to a variety of uses and provide several benefits to homeowners and businesses. Installation of IT and data surveillance systems help in reducing insurance premiums, managing security in airports and large malls and improving the security of your home. Security systems can be used outside or inside the buildings. There are systems that are specifically designed for use in homes and by businesses. Therefore, you must be sure that you are buying the system that is best suited to your requirements.
