How To Install A Cctv Dvr Network If you want to install a CCTV DVR network, it is important to first know exactly what these types of systems are. CCTV cameras have been used in many different applications for many years and most people have heard of them. DVR versions, however, are slightly newer, although technology has already advanced and more advanced cameras now exist. However, the DVR version is the most affordable of the really good systems. Basically, a wireless CCTV system is usually used by businesses. It allows them to review all processes within an industrial plant, including those areas that are not accessible to humans. For instance, in chemical factories, it is very useful to have a CCTV camera available in contaminated areas that can, for instance, monitor radiation levels and air quality before agreeing to send someone in. Or, they can be used to monitor outside influences on bacteria or viruses, without endangering workers. These are but a few examples of how these cameras can be used in an industrial setting. CCTV DVR is also commonly used in public places. They are commonly seen on streets with high crime rates, to act as a deterrent to delinquents. People also frequently use CCTV cameras in apartment complexes and parking lots, or any other large areas with high levels of movement. Through these images, crimes have been both solved and prevented. Furthermore, people generally feel safer when they know this type of security is in place, although a balance needs to be found between feeling secure and feeling watched. In order to install a wireless CCTV system, however, it may be better to contact a professional. Usually, the system will come with clear instructions, and if you are a home user, there is nothing wrong with installing it yourself. However, for larger businesses, this is perhaps not the best option. By using a professional to set up the CCTV camera network, an organization guards itself against many network issues. Networks are always open to hackers trying to gain access, which is hard to prevent unless you know exactly what you are doing. Particularly if you are using multiple cameras across a large network, this can be a real threat. Once the system is installed, however, do make sure that you change all the access codes that you have been provided with. After all, it is not unheard of for people who work for a security company to be tempted to do bad things.
