This system was often used for surveillance in areas that required security. Now, these goals have been changed in order to improve and increase work efficiency and reduce costs, etc. For example, the camera was installed in the store just to monitor customers and prevent theft and misbehavior. While today, the capabilities of this system in stores can have a great impact on the amount of sales and profits.
Many offices, streets and even houses are equipped with such technology. According to different purposes, cameras with various capabilities are used by people. The ability to recognize faces in CCTV cameras allows the collection or organization to have a library of the faces of its employees. By using it, entry and exit are allowed by identifying each person. A CCTV camera with the ability to count people makes management and monitoring easier and more targeted in crowded and high-traffic places. By collecting information from these types of cameras, better decisions are made in the distribution of manpower in times of need. Other technologies such as night vision, intrusion detection, motion detection, WDR and hundreds of other innovations have made monitoring and security purposes much easier than ever.
What are the CCTV components?
In general and in simple terms, the camera is part of a closed-circuit system that transmits images to others through a cable. The receiver of the images can record and display the images. Based on the type of selected system, the components are of different types.
The main components of CCTV are: >
▪️CCTV camera: It is responsible for receiving images from the desired location and sending them to the server.
▪️Server: in closed circuit The server device (DVR or NVR) receives and records the images sent from the cameras. It also provides the possibility of managing them. Memory or hard disk: it enables the recording of images on the server. Cable: connecting the camera to Server. Power supply: In order to provide power to the cameras, a power supply is needed to change the voltage of the city to 12 volts. Power cable: > Connecting cameras and source Power supply. Connections: connecting cables to closed circuit equipment through special sockets.
CCTV
CCTV cameras are produced and designed in different types for different uses. You can find a suitable camera for any user and surveillance purpose in the market, even for your budget. Therefore, I suggest that before buying, you should do research in the market from a reliable source and then make a purchase. CCTV cameras are divided into different categories based on shape, application, technology, lens and image resolution. The shape of CCTV cameras is one of the categories of cameras that most customers use.
CCTV camera with different body and appearance:
▪️ Dom camera: This camera is mostly used in indoor and roofed environment. .
▪️Bolt Camera: Cameras that are suitable for the outdoor environment. Special
▪️Box camera: cameras suitable for industrial environments with a separate lens
▪️Fisheye camera: Camera for places with high ceilings and for 360-degree monitoring of the environment
▪️Cube camera: Internal camera with sound recording and two-way audio communication
▪️Needle camera: Very small cameras with the ability to hide in Behind objects

What are the types of CCTV technology?
There are different types of CCTV cameras that are produced with different technologies. Each of these models are suitable for different uses and places, and it is very important to buy a CCTV camera according to the user's needs. In general, CCTV cameras are classified into the following three categories according to the type of technology.
Analog CCTV Camera: The first CCTV cameras were built based on the analog system and the oldest type of camera. are closed circuit The technology used in these cameras is very old and now their use is almost obsolete.
Analog HD CCTV: A big evolution in analog systems to The use of new HD analog technology was in recent years. These systems overcome the limitations of analog cameras, including low image quality, and were able to be a suitable alternative to them. Different types of HD analog surveillance cameras, including AHD, HDTVI, HDCVI, and HDSDI, have come to the market. Network or digital work on the network platform, these systems can send images and other information through computer networks. The use of digital surveillance cameras or networked systems in general in large projects has more economic justification.
