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.<ref>{{cite web |date=19 December 2013 |title=Global value of IP camera sales now close to 50% of CCTV cameras sold, but... |url=http://www.networkwebcams.co.uk/blog/2013/12/19/the-global-value-of-ip-camera-sales-is-close-to-50-of-total-cctv-cameras-sold-worldwide-but-they-are-not-yet-plug-and-play/ |website=Network Webcams}}</ref> IP cameras use the [[Internet Protocol]] (IP) used by most [[local area network]]s (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 remotely on a computer or phone via an internet connection.<ref>{{cite web |title=Remote Escort |url=https://www.securitasinc.com/services/remote-guarding/remote-escort/ |website=Securitas |access-date=14 June 2022}}</ref> IP cameras are considered part of the [[Internet of things]] ([[Internet of things|IoT]]) and have many of the same benefits and security risks as other IP-enabled devices.<ref>{{Cite web|url=https://www.trendmicro.com/vinfo/mx/security/news/internet-of-things/securing-ip-surveillance-cameras-in-the-iot-ecosystem|title=Securing IP Surveillance Cameras in the IoT Ecosystem - Noticias de seguridad - Trend Micro MX|website=www.trendmicro.com|language=es|access-date=2020-02-18}}</ref> [[Smart doorbell]]s are one example of a type of CCTV that uses IP to allow it to send alerts.

Main types of IP cameras include fixed cameras, [[Pan–tilt–zoom camera|pan–tilt–zoom]] (PTZ) cameras, and multi-sensor cameras.<ref>{{cite web |url= https://internationalsecurityjournal.com/selecting-most-suitable-cameras/ |title= Selecting the most suitable cameras to monitor large areas |website= internationalsecurityjournal.com |date= 19 November 2020 |publisher= International Security Journal |access-date= 2021-06-23}}</ref> Fixed cameras' resolution typically does not exceed 20 [[Pixel|megapixels]]. The main feature of a PTZ is its remote directional and [[Zoom lens|optical zoom]] capability. With multi-sensor cameras, wider areas can be monitored. Industrial video surveillance systems use [[network video recorder]]s to support IP cameras. These devices are responsible for the recording, storage, video stream processing, and alarm management. Since 2008, IP video surveillance manufacturers can use a standardized network interface ([[ONVIF]]) to support compatibility between systems.<ref>{{cite web |url= https://www.ifsecglobal.com/onvif/ |title= ONVIF: a guide to the open security platform |website= ifsecglobal.com |publisher= IFSEC Global |access-date= 2021-06-23}}</ref> For professional or public infrastructure security applications, IP video is restricted to within a private network or [[VPN]].<ref>{{cite web |title=Dispelling the Top 10 Myths of IP Surveillance |url=http://www.axis.com/files/articles/ar_10myths_secinfowatch_us_0512.pdf |url-status=live |archive-url=https://ghostarchive.org/archive/20221009/http://www.axis.com/files/articles/ar_10myths_secinfowatch_us_0512.pdf |archive-date=2022-10-09 |access-date=30 March 2016}}</ref>
