Introduction
A CCTV system, known as closed-circuit television, is important for safety today. It uses video to watch and record events in a certain area. Security cameras are set up in important locations for this reason. Unlike regular TV, CCTV sends its video to only a few screens. This setup works well for careful monitoring.
Basics of CCTV Technology
CCTV systems mainly use cameras to take pictures. These pictures are sent to a device that records them. This system lets you see and save the images. In the past, it worked with analog signals, which moved through coaxial cables.
Modern CCTV systems have quickly moved to digital and internet systems. This change allows for clearer video quality. It also lets you see the video from far away and helps connect to other security systems.
What Is CCTV and How Does It Function?
Closed circuit television (CCTV) uses cameras that send video to certain monitors. This creates a closed loop for watching. The main role of a camera system is to take a steady series of images from selected spots. These images go to a recording device, which can be a digital video recorder (DVR) or a video recorder (NVR).
You can watch the recorded video live or check it after. Camera systems can be simple, with only one camera, or very complex, with several cameras. This setup gives complete coverage of big areas.
CCTV cameras can record and store video. This is why they are helpful for security. They provide evidence and can aid in investigations when incidents occur.
Key Components of a CCTV System
A typical CCTV system has several important parts that work together. Their job is to capture, send, record, and show video footage. The main part of the system is the camera. These cameras act like the eyes of the system. They take photos and send them to a central unit that records everything.
The recording unit, like a DVR or NVR, handles video data. It is the brain of the system and processes video from several cameras.
A power supply is needed to turn on the cameras and the recorder. A storage device, like a hard drive, stores the recorded video. The size of the storage can change based on how advanced the system is.
Types of CCTV Cameras
There are many types of surveillance cameras out there. Each type meets different security needs. Dome cameras get their name from their round covers. People often use them for indoor monitoring. They have a low shape and can cover a wide area.
Bullet cameras are named after their round shape. They are mostly used outside because they can handle various weather conditions. These cameras also have a clear field of view.
Dome Cameras and Their Uses
Dome cameras are popular for indoor use. They fit in well with their surroundings because they have a simple design. Their round shape makes it difficult to tell where the camera is pointing. This provides added security.
One big benefit of dome cameras is that they have a wide field of view. They are able to see a large area clearly. Because of this, you can cover larger spaces with fewer cameras.
Dome cameras are good for many security needs. You can use them to watch what happens in stores and offices. They also work well for keeping homes and parking garages safe. These cameras help prevent theft, damage, and other problems.
