Closed circuit televisions, or CCTVs, were introduced in the 1940s when German engineers wanted to observe their rocket launches from a remote location. They have gained immense popularity since then and are being used in many different fields today. The system involves transmission of signals from specific video cameras to televisions located in another location. You can see them in military installations, airports, retails, banks, casinos, distance education centres, and industrial plants.
CCTVs have been known to deter crime. They help you identify the perpetrators and prosecute them with right evidence. They can be a great addition to your security systems, and help you monitor your premises at all times from a convenient location. Institutions and business owners have, therefore, developed a keen interest towards installing CCTVs. Cameras form an important aspect of every CCTV system. Learn the specifications of the lens and other technical details before investing in one. Your manufacturer should help you provide the right guidance. The prices will vary depending on your model. Different retailers may also offer the same system for a different price. It is important to do your homework before purchasing and installing CCTVs around your home or business.
Although CCTVs are easy to install and use, they can experience problems from time to time. The baseband or composite signal used for transmission of CCTV images is a raw signal. Experts believe that they require cables with a copper core. However, many people use aluminium cables because they are cheaper. This misuse of the coaxial cable can lead to some serious complications. Your CCTV maintenance company can help fix the problem at all times.
Other CCTV maintenance problems may be related to poor cable connection and installation. Storms and other extreme conditions may alter the position and direction of existing systems. They may also disrupt the connections. The signal receptors in the television sets can cause problems occasionally. This can prevent the images from getting displayed on the television screen. Poor picture tubes and television cable connections can also lead to problems.
If your CCTV system is facing issues, contact your maintenance company. The technical experts will diagnose the problems and fix them accordingly. Some CCTV systems may require regular maintenance. Your CCTV maintenance professional will visit your location and ensure everything is working well.
In fact, regular maintenance will increase the lifespan of your CCTV system. The maintenance package will include annual checks of the cameras and minor repairs. The technicians will also check the DVR status and power supply. They will clean the camera lenses, and adjust their focus and vision. They will assess the recording and playback quality of the images along with transmission of images. The experts will also conduct tests, and log all the results for future reference.
