CCTV is one of the main components of closed circuit system. This component of the surveillance system is supposed to receive the image and send it to the recording device for storage and processing. There are different types of CCTV cameras in the market, each of which is more suitable for a specific use. In order to be able to choose the most suitable camera, it is better to get more information in this field, then make a purchase.
🟧 Record (NVR/DVR) 🟧
The recording device or recorder is another part of the CCTV camera that is very important. This device receives images from CCTV cameras and then stores them after processing. Recorders or recording devices are also designed and produced in two analog and network technologies. For an analog CCTV system, you must use analog cameras and an analog recording device. Recording devices in the analog system are called DVRs, which have different features and capabilities. If you want your surveillance system to be networked, use network cameras and network recording device or NVR.
🟧 Monitor or display
Among the other components of the CCTV camera, we can mention the display. This part of the CCTV system is used to view the images of the cameras. Based on the dimensions of the project and user, the number of monitors and screens may be more than one. With the increase in the number of monitoring systems in projects, you will need a room for monitoring.
🟧 Adapter or power supply
CCTV cameras and recording devices need electricity to turn on. The cameras work with a current of 12 volts. Therefore, an adapter is needed to convert 220 volt municipal electricity to 12 volt with different amperes. The power supply can be central or installed separately for each camera.
🟧 Hard to store information
The hard disk is another component of the CCTV camera, which is also important. The external hard drive of the CCTV camera is inserted into the DVR/NVR recording device and all CCTV images are stored in it. According to the type and model of the hard drive used, the number and capacity will be different. Be careful to use the appropriate hard drive for the CCTV system. In the WD brand, the purple hard drive is suitable for surveillance and closed-circuit systems.
🟧 Facilities and jackets
The CCTV connector and plug is responsible for connecting the cables to the camera and device and other CCTV components. Depending on what monitoring system you are installing, the plugs and connections will be different. For example, the main plug used in analog systems is the BNC plug. Meanwhile, you use sockets in networked systems. To connect the microphone, you must use the appropriate plugs for that microphone.
🟧 Kabul
The cable is another part of the different parts of the closed circuit system whose task is to send data and electricity. Some cables can only send power or data, while there is another type of cable that is produced as a hybrid cable and can send data and power at the same time. The quality of the cable affects the quality of sending images. Is. If the cable is not of good quality, the images will be sent to the device with noise or interruption. This issue is very important in high-sensitivity applications.

Switch and modem
Switch and modem are components that are often used in networked systems. Of course, you will need a modem to transfer images in analog systems. The switch also has different types, the number of ports and PoE can be different according to the specifications of the CCTV system. The PoE feature helps you to face less cabling in the CCTV surveillance system, and the power of the device and cameras can be supplied through the network cable.
🟧
You can use peripheral and other components in closed systems. For example, microphone, rack, duct, flexi pipe, UPS device, etc., these equipments are effective in the installation and operation of the system and how it works. If your CCTV cameras are not equipped with internal microphones, you can easily buy external microphones and add them to your system. Rack, duct, flexi pipe are used to protect CCTV components in surveillance system. In addition, it greatly contributes to the cleanliness of the installation work and preventing the system from getting messy.
