CCTV, also known as closed-circuit television, is a security monitoring system that allows you to always keep a close eye on your property or business. After all, it’s just an extra pair of eyes that are always wide awake. CCTV has become more popular in recent years, and it is no longer just a company security element, but also a sought-after necessity among local houses too. Learn the fundamentals of CCTV Cameras to get a better insight into their functioning.
CCTV security systems include monitors and cameras for viewing live events, as well as recorders for archiving footage for later use. These CCTV camera-based security systems differ from standard television sets as they do not receive public broadcast footage. They only receive video from security cameras installed on or near the local business.
How does CCTV work?
- The camera, lens, monitor, and videotape/recorder are the four major components of a CCTV system.
- The camera is the most important of these components because it is the one that captures the images.
- The camera operates in the same manner as a standard camera, with the exception that it can be left to operate on its own.
- The camera has a motor that assists it in moving the zoom parts.
- Once an image is captured by the camera, it is transferred to the monitor and recorded on a videotape or DVR.
- The type of lens on the camera determines its ability to zoom in and out.
- A series of images is captured by the camera and transmitted as a signal to the recording and display devices.
- The video source is captured by the camera itself. The light stream through the lens is captured by an opened aperture at the front of the camera.
- A digital chip inside the camera captures the light stream and converts it into a series of images.
- This camera captures this image sequence and transmits it via cable or wirelessly.
CCTV security systems have seen significant technological advancements in recent years. These advancements have increased the effectiveness of security systems in apprehending criminals during a crime. Not to mention that they are an effective safeguard for your company’s assets. CCTV security systems are becoming increasingly popular for the above and many other reasons.
