Understanding CCTV Components: The 4 Parts Every System Requires
If you’re building a CCTV Camera System, you have two camera options: Internet Protocol (IP) or analog. IP is usually the preferred choice due to its compatibility with most devices. Many different types of cameras can be installed, for example -dome cameras, bullet cameras, covert cameras.
Depending on how many angles you want to cover, how many cameras you will need in that specific area, how much resolution or detailing you require when you choose your preferred cameras.
2. The Network Video Recorder
While some of the features of a camera system are decided by the camera itself, the system relies heavily on the network video recorder (NVR). Every camera that is part of the security camera system is connected to the NVR which processes the signals and records the images that the camera sees.
The NVR is also connected to a monitor to allow you to watch what is happening on the security camera system. Modern security camera systems will allow you to remotely view your cameras on a computer or mobile device.
3. Monitoring Station
A monitor arguably facilitates the most important function of a security camera: viewing recorded images and footage. Deciding how many monitors you’ll need is dependent upon what, and which area you are monitoring. You wouldn’t need more than three to five screens if you aren’t operating in a large-scale facility. Although if your requirements change, you can easily add or remove monitors anytime to match the compatibility of your camera.
4. The Wiring
Wiring a security camera system can run from extremely easy to extremely difficult. The most easy systems for installation are the chief ones that are designed to be installed at home. These cheap systems black a lot of features though so if you really want a security system that will help you, you are going to need a professional installer. That is because wiring has to be run through the walls and into the NVR.
Each camera needs to connect to the NVR and that process often means working through walls. They can also mean wiring directly into power depending on the power supply.
There are some camera systems that allow you to wirelessly connect the camera to the NVR. These camera systems will still need power wire to the camera but they do offer the ability to not have to run cables everywhere. These systems are not as reliable as wired systems though.
