Closed-circuit television (#CCTV), also known as video surveillance

✅ Camera Types:
#Analog
With a traditional analog video camera, we connect to our digital video recorder, DVR. The information from the DVR is received, stored, and compressed on a hard drive.
#Digital (IP)
A digital system brings us up to date with CCTV. The system itself is a bit more involved and costly, but well worth it in the end. It works similarly as analog, but instead of a DVR, we have an NVR, network video recorder.
⭕ Cameras can be grouped into :
Fixed : Fixed cameras have a fixed field of view and cannot be moved
Pan-tilt-zoom (#PTZ) : PTZ cameras can pan (move left and right), tilt (move up and down), and zoom in and out
Dome Camera : Dome cameras are housed in a dome-shaped enclosure that helps to protect them from the elements
