What is a CCTV security monitor?

A CCTV Monitor is a display screen that is specifically built for use with Closed Circuit Television systems.

These monitors almost always have BNC type connectors, making it quicker and easier to plug in an analog CCTV camera directly. They might also have multiple inputs to view multiple cameras at the same time.

Overall, there isn't a huge difference between your normal monitor and a CCTV monitor, but you usually get what you pay for, also, so buying a quality CCTV-specific Monitor for your project is always recommended.
