Closed-circuit television (CCTV), also known as video surveillance. is the use of video cameras to transmit a signal to a specific place, on a limited set of monitors. It differs from broadcast television in that the signal is not openly transmitted, though it may employ point to point (P2P), point to multipoint (P2MP), or mesh wired or wireless links. Though almost all video cameras fit this definition, the term is most often applied to those used for surveillance in areas that may need monitoring such as banks, stores, and other areas where security is needed. Though Video telephony is seldom called ‘CCTV’ one exception is the use of video in distance education, where it is an important tool.

A growing branch in CCTV is internet protocol cameras (IP cameras). It is estimated that 2014 was the first year that IP cameras outsold analog cameras. IP cameras use the Internet Protocol (IP) used by most Local Area Networks (LANs) to transmit video across data networks in digital form. IP can optionally be transmitted across the public internet, allowing users to view their cameras through any internet connection available through a computer or a phone, this is considered remote access. For professional or public infrastructure security applications, IP video is restricted to within a private network or VPN, or can be recorded onto a remote server.

Integrated systems allow different security systems, like CCTV, access control, intruder alarms and intercoms to operate together. For example, when an intruder alarm is activated, CCTV cameras covering the intrusion area are recorded at a higher frame rate and transmitted to an Alarm Receiving Centre.

Many consumers are turning to wireless security cameras for home surveillance. Wireless cameras do not require a video cable for video/audio transmission, simply a cable for power. Wireless cameras are also easy and inexpensive to install, but lack the reliability of hard-wired cameras.Previous generations of wireless security cameras relied on analog technology; modern wireless cameras use digital technology which delivers crisper audio, sharper video, and a secure and interference-free signal.
