Sophisticated Features in CCTV Camera Systems That Enhance Security Vigilance

Security camera systems and CCTV surveillance are absolutely essential for vigilance at homes, offices, banks, shopping malls, clubs, hotels and other places. Security camera systems are the most popular vigilance systems. Major types of CCTV cameras include dome cameras, bullet cameras and box cameras. Many CCTV camera systems have infrared night vision to facilitate vigilance in darkness. The security camera systems allow zooming at various distances at various angles for maximum security vigilance. Security systems Wollongong and CCTVs Wollongong are available at affordable rates from security service providers.

There are two kinds of CCTV cameras - analog cameras and IP cameras. Analog CCTV cameras are most popular. IP CCTV camera systems also provide several useful features that make them important for commercial complexes and businesses. We should remember that coaxial cables can run up to three hundred feet and this factor might pose a problem for large buildings. The IP cameras have IDF locations. The IDF network switches connect network traffic to MDF. IDFs are located in various parts of a building and MDF is the server room. The network video recorder is located at the MDF. Choosing the right kind of chip is important for IP security camera systems. CMOS chips are cheaper and provide higher megapixels. PoE (Power over Ethernet) allows IP cameras to have a single cable for power supply to the camera as well transmission of video footages. CAT5e or CAT6 can be used for the IP cameras.  

There are two types of night vision security cameras. The first type of security camera uses infrared light for night vision. The second type of night vision camera makes use of thermal energy. Most crimes and illegal intrusions occur at night so night vision cameras are absolutely essential for night vigilance or vigilance during darkness. The infrared night vision cameras use infrared light to illuminate the premises and then record images. Infrared light sources cannot be detected by people in the premises. Factories and industrial complexes mainly use thermal energy dependent night vision cameras. These cameras detect the heat radiating from humans and objects and later transform this into image form.
