How does modern CCTV work?
Answer: It depends on what type of system you are using. Systems are defined by their cameras. Analog and IP cameras are the two most common types of cameras used today.
Analog cameras have been used in CCTV systems for many years. The most common camera type in the field is still analog. Analog systems consist of a camera, or series of them, with dedicated wires that are fed to a recording device. The video is recorded on-site and then stored.
IP cameras perform the same functions as analog ones but have a number of additional capabilities. IP cameras offer higher-resolution images and greater flexibility. Users can also email images to be reviewed. Insurance companies often prefer IP systems, or even demand them.

IP cameras use an IP network (IP is the acronym for Internet Protocol), which is often the same network that the rest of the company uses. A separate network with category 5 wiring is available if bandwidth is an issue. Video data can be stored on a server in either case, so it doesn’t matter if the data is located at a remote site or on-site.
Although storing so much data can be an issue, IP CCTV systems often have software that controls how long and in what quality the video will be stored. Video can be compressed after a certain time to save space on the storage device.
Although many people use CCTV to describe both IP and analog cameras, it should only be used to describe analog cameras.
With the powerful software called video analytics, IP security cameras can be programmed so that they “watch” suspicious activities. For example, a camera mounted on an air intake can be programmed so that it only records video when the area around the intake has been disturbed.
