Introduction
I think this question comes to mind when we walk into a shop or pass by a street and see a small camera on the wall We know it is watching but we do not know how it works We ask ourselves how does CCTV work and what happens to the video it records
We are living in a time where safety matters That is why we should understand how CCTV works what parts are used and how it helps protect homes shops and public places
What Is CCTV
CCTV means Closed Circuit Television It is a system that uses cameras to watch and record what is happening in a place like a home shop school or street The video is shown on a screen and sometimes saved so that it can be watched later
We use CCTV to keep an eye on things and to feel safe If something wrong happens we can check the video and know what happened
How CCTV Works Step By Step
I think it helps to break it down into simple steps Here is how CCTV works
Step One Image Capture
The camera captures video using a lens and image sensor It turns light into electrical signals This is the first step where the camera sees what is happening
Step Two Signal Transmission
The video signal is sent from the camera to a recording device This can be done using cables or wirelessly depending on the type of system
Step Three Recording
The recording device saves the video This is usually a DVR or NVR DVR means Digital Video Recorder and NVR means Network Video Recorder
Step Four Display
The video can be seen on a monitor or screen This helps us watch live footage or check old recordings
Step Five Storage
The video is stored on a hard drive or cloud system We can keep it for days weeks or months depending on the storage size
Types Of CCTV Systems
We should know that there are different types of CCTV systems Here are the main ones
Analog CCTV
This is the old type It uses coaxial cables and a DVR to record video It is simple and still used in many places
Digital CCTV
This uses digital signals and gives better quality It is faster and more reliable
IP CCTV
This uses internet protocol and connects through a network It allows remote viewing and control from mobile or computer
My Personal Experience
I think sharing my experience will help you I installed a CCTV system at my shop after a small theft I chose a simple analog system with four cameras and a DVR
The cameras were placed at the entrance counter and storage area I could see everything on a monitor and check recordings later One day a customer dropped his wallet and the video helped us find it quickly
That moment made me trust CCTV and understand how useful it is
