What are the parts of CCTV?
The three basic components of all CCTV security systems are the camera, the monitor, and the cable. While other supplemental components may be added into more complex systems, the camera, monitor and video cable form the core of all CCTV security systems.
How do CCTV systems work?
CCTV works by the camera or cameras taking a constant sequence of images that are then transmitted by cable or wirelessly (depending on the chosen system type) to the recording device and then on to the display monitor, which enables an individual to see the sequence of images as video footage.
What is a CCTV camera made of?
A CCTV lens is made from glass and focuses light from the scene onto the camera’s image sensor.
How are CCTV cameras connected?
With a wireless security camera, the video signal—and, with some, the audio signal as well—is transmitted over the internet or other wireless network to a receiver that connects to your viewing and recording device. Many people use computers or Cloud storage accounts to save the video footage for later viewing.

What’s the difference between surveillance cameras and security cameras?
