If you’re building a CCTV Camera System, you have two camera options: Internet Protocol (IP) or analog. IP is usually the preferred choice due to its compatibility with most devices. Many different types of cameras can be installed, for example -dome cameras, bullet cameras, covert cameras.

A monitor arguably facilitates the most important function of a security camera: viewing recorded images and footage. Deciding how many monitors you’ll need is dependent upon what, and which area you are monitoring. You wouldn't need more than three to five screens if you aren't operating in a large-scale facility. Although if your requirements change, you can easily add or remove monitors anytime to match the compatibility of your camera.

Depending on the type of surveillance system, and cameras you choose, you will need supporting technologies like cables, and routers to be integrated into your system for a seamless connection. For example, wireless systems require a router, while wired versions do not.

Therefore, choose the cables, and wires after selecting your cameras, and monitors according to your unique needs.

The video recorder is the device where video recorded on the camera gets processed for storage & viewing. There are two types of video recorders: DVR (Digital Video Recorders) and NVR (Network Video Recorders).

Your CCTV security system is only as good as the hard disk backing it. The storage device for a security camera system should be able to record, store and re-play videos non-stop from multiple feeds. Regular hard drives that are used in PCs and Laptops are ill equipped to handle CCTV storage needs.
