A CCTV (Closed-Circuit Television) security system is a security system that is mainly based on a camera and a closed network or circuit. The reason why people prefer CCTV security systems over more modern security systems is because CCTV security systems are hooked up on closed networks or circuits, and since that is so, no one can hack into them or gain access to them externally. A person can either purchase a ready-made CCTV security system, or they can purchase the components required to install a CCTV system themselves. Since the latter is cheaper, most people decide to go with it.
Well, if someone wants to create their very own CCTV security system, they need to know what components make up the typical CCTV security system. The following are all of the components which a Closed-Circuit Television security system needs to have:
A CLOSED-CIRCUIT TELEVISION CAMERA
The first and most important component which a CCTV security system is (obviously) needs to have is a CCTV camera. Without a Closed-Circuit Television camera, a Closed-Circuit Television security system is incomplete. If a person wants a low-scale surveillance and security system, they only need one CCTV camera. However, if a person wants a large scale surveillance and security system that has its eyes on a large area and provides multiple viewing angles, they will have to use multiple CCTV cameras to build their CCTV security system.
The second most important component which a basic CCTV security system needs to have is a computer. If it’s not connected to a computer, a CCTV camera is useless as it will not have any place to transmit and store data. In addition, the computer a person chooses to use for their CCTV security camera must have a considerably large amount of free space depending on how much CCTV footage they want to store on it.
A basic CCTV security system must have a medium which it can use to detect any breaches in the integrity or security of the area it is observing so that it can alert or notify a responsible entity. This is where motion sensors come in. If a CCTV security system has motion sensors, it will be able to pick up even the slightest movements in the area being observed by the system and alert the owner or a responsible entity, and that is why the average CCTV security camera needs to have them.
