Security cameras
Security cameras (security camera / surveillance camera / security camera), like other devices and electronic equipment based on advanced technologies, have undergone a very rapid evolution in a short period of time and have a growing future. is For several decades, the use of this equipment was only limited to defense and government organizations and large industries, but over time and with the reduction in the cost of setting up such systems, along with the increasing security and protection needs of industries, small businesses, homes and villas, the use of security systems has become a matter of course in all industries and businesses and even homes and stores.
Security camera system components
in any system of security cameras; The set of cameras, the image recording device (equipment for displaying, storing and managing images), the image transmission system, along with other peripheral equipment of CCTV cameras and the accessories of CCTV cameras constitute the components of the security camera system.
1) Case or Cover Security Cover
There are two types of camera cases available. In the first type, the camera boards are placed directly inside the case. In the second type, which is for industrial cameras, the camera itself is placed inside the case or cover.
2) The main board of the surveillance camera, also called the PCB range of the surveillance camera
On the PCB board of the surveillance camera, parts such as light-sensitive sensors (CCD or CMOS or DIS or HDIS), ICs and electronic parts for image processing (DSP) as well as image conversion and transmission parts They are processed on the output media (RG59 cable or network cable).
3) Night Vision Board of Protective Camera Simply called the IR View Camera at Night
In night vision security cameras, a separate board (IR board) that has a light-sensitive sensor and a number of infrared LEDs whose task is to emit infrared light when the lux of the light received by the highly sensitive sensor drops. It is responsible for the light (darkening of the environment).
4) the protective camera lens
Lenses are either fixed or varifocal; They are either analog or megapixel; They are either installed inside the security camera itself or installed separately on the camera.
How to operate a security camera system
1) Video recording or taking pictures by a set of video cameras
2) Transferring the image from the security camera to the system for displaying or storing CCTV images
3) processing images by the system and storing them on the hard disk of the surveillance system
4) outputting images from the CCTV recording device or image storage server to a display
Using the security camera
In general, all the uses of security cameras can be summarized in the following cases:
Protection, protection, safety, crime prevention and violation of laws
Control, management and Monitoring of places/activities/processes
Use in different industries and technologies
Education and research
