Types of CCTV Systems
CCTV IP System
As opposed to analog formats, an IP camera records data digitally and stores it on a hard drive. IP cameras aren’t just digital cameras, though. “IP camera” is short for “Internet Protocol camera,” and it’s called that because it can connect to the internet.Because IP cameras store images as data rather than physically on a tape, the image feed can be viewed from just about anywhere with an internet connection. IP cameras don’t need to be hard-wired; they can connect to Wi-Fi networks and send data wirelessly.
CCTV Analog System
“Analog” refers to methods of transmitting data and feedback through physical means, rather than digital ones. If you listen to music in an .mp3 format, it’s digital; if you’re listening to it on a vinyl record, it’s analog.An analog camera records video by taking in light through a lens and recording it on a physical medium, usually tape or film. It is possible to monitor the feed of an analog CCTV camera in real time — imagine a security guard watching a bank of monitors in a movie — but it almost always requires a hard-wired connection, i.e., there must be a physical cable between the monitor and the camera.
