How does CCTV work?

Whenever the image of any person or object falls in the lens of the camera, its image falls in the sensor installed in the circuit board of CCTV. In technical language, the camera sends the image analog signal to the sensor.
  • Sensor: The analog signal falling on the sensor creates a digital copy of that image and sends it to the main circuit board of CCTV. We can say that the sensor converts the analog signal into digital signal.
  • Circuit Board: After the above process, the information collected by the sensor goes to the main circuit board. Here it is decided by the circuit board that the information is to be shown in the display device and the data is to be saved in the storage hard disk.
  • Display and Storage Device: The main and last part of CCTV is the display device or screen on which you can easily watch the video recorded by the camera. CCTV with display has the option to save video footage. Which is saved in the hard disk by the storage device.
