However, digital technology, which was once a figment of imagination, now facilitates the present CCTV systems. Some of the features of modern CCTV systems are:
- Real-time feeds through remote devices and monitors
- Wireless installations with solar-powered batteries
- Automated sensors with any movement or breaches
- Alarm monitoring alert for instant responses
- DVRs with greater storage, speed, capacity, and image quality.
- Digital footage with simple and quickly accessible features.
Components of a CCTV System
A common CCTV system has three major parts. Each of them has a specific function with a crucial role as each other. When installing security for your area, check out the following components.
Cameras
The camera is the central aspect of the CCTV system. You can choose the camera’s resolution and angles per the specific area. Cameras are primarily of two types – Internet Protocol and Analog. People commonly use IP cameras compared to analog ones because they are compatible with advanced technology. These cameras also come in different configurations, categorized as bullet-shaped cameras, Dome cameras, C-mount, and Pan-tilt-zoom.
Video Recorders
CCTV video recorders are responsible for recording the video on the camera and processing it for storage and viewing. The types of video recorders are:
1. DVR (Digital Video Recorder)
DVR records digital video to a storage system, like an SD card or disk drive.
2. NVR (Network Video Recorder)
CCTV with IP camera opt for NVR for simple integration and compatibility. It simplifies the surveillance system through a plug-and-play format.
Cabling and Connectivity
Depending on the type of CCTV system, it needs the support of cables and routers. They will integrate it into the system for seamless functioning. The primary types of cabling are:
Coaxial Cables
People highly use coaxial cables due to their excellent shielding quality. It helps prevent signal inferences and fastens data transmission.
Network Cables (Ethernet)
These cables are the most common ones used in hard-wired security CCTV systems. It has eight insulated copper wires twisted around each other to decrease signal interference.
Working Principles of CCTV
CCTV systems can be easily scaled up and down based on the elements. However, the working principle is the same behind the screen.
Camera Operation
The camera will initially click the multiple pictures of the specific area in a continuous sequence. It will wirelessly render to the chosen system via an internet-based or wired connection.
Signal Transmission
The camera will capture the analog signal in the analog system and transfer it via coaxial cable to DVR. It converts the analog signal to a digital signal, compressed and stored on a hard drive. You can view the footage on the monitor. They will set up the DVR to transmit the videos over the internet. The analog system focuses on the single and efficient streaming of camera signals using a single IP address.
They will process the digital signals captured with the camera using LAN (Local Area Network) and record them via NVR. It streams pictures and video from every camera, broadcasting over the Internet for remote viewing.
