An\u00a0Internet Protocol camera<\/b>, or\u00a0IP camera<\/b>, is a type of\u00a0digital video camera<\/a>\u00a0commonly employed for\u00a0surveillance<\/a>, and which, unlike analog\u00a0closed-circuit television<\/a>\u00a0(CCTV) cameras, can send and receive data via a computer network and the Internet. Although most cameras that do this are\u00a0webcams<\/a>, the term\u00a0IP camera<\/i>\u00a0or\u00a0netcam<\/b>\u00a0is usually applied only to those used for surveillance that can be directly accessed over a network connection.<\/p>\n

Some IP cameras require support of a central\u00a0network video recorder<\/a>\u00a0(NVR) to handle the recording, video and alarm management. Others are able to operate in a decentralized manner with no NVR needed, as the camera is able to record directly to any local or remote storage media. The first centralized IP camera was Axis Neteye 200, released in 1996 by Axis Communications<\/p>\n

The first centralized IP camera, the\u00a0Axis Neteye 200<\/i>, was released in 1996 by\u00a0Axis Communications<\/a>\u00a0and was developed by the team of Martin Gren and Carl-Axel Alm.[3]<\/a><\/sup>Although promoted on its ability to be directly accessible from anywhere with an internet connection,[4]<\/a><\/sup>\u00a0the camera was not capable of streaming real-time motion video, instead being limited to showing a snapshot image each time the camera was accessed. At the time of launch, it was considered to be incapable of operating as a motion camera due to what was conceived as “enormous” bandwidth requirements, thus was aimed primarily at the tourism industry.[5]<\/a><\/sup>\u00a0The Axis Neteye 200 was not intended to replace traditional analogue CCTV systems, given that its capability was limited to just one frame per second in CIF, or one every 17 seconds in 4CIF resolution, with a maximum resolution quality of 0.1MP (352×288).[6]<\/a><\/sup>\u00a0Axis used a custom proprietary\u00a0web server<\/a>\u00a0named OSYS, yet by the summer of 1998, had started working on a software port toward\u00a0Linux<\/a>\u00a0to operate its cameras.[7]<\/a><\/sup>\u00a0Axis also released documentation for its low-level\u00a0application programming interface<\/a>\u00a0(API) called “VAPIX”, which builds on the open standards of\u00a0HTTP<\/a>\u00a0and\u00a0real time streaming protocol<\/a>\u00a0(RTSP). This\u00a0open architecture<\/a>\u00a0was intended to encourage third-party software manufacturers to develop compatible management and recording software.<\/p>\n

The first decentralized IP camera was released in 1999 by Mobotix. The camera’s Linux system contained video, alarm, and recording management functions, thus the camera system did not require licensed video management software to manage the recording event, or video management.[8]<\/a><\/sup><\/p>\n

The first IP camera with onboard video content analytics (VCA<\/a>) was released in 2005 by Intellio. This camera was able to detect a number of different events, such as if an object was stolen, a human crossed a line, a human entered a predefined zone, or if a car moved in the wrong direction.[8]<\/a><\/sup><\/p>\n

Video standards.<\/span><\/h2>\n

Previous generations of analog CCTV cameras use established broadcast television formats (e.g.\u00a0Common Intermediate Format<\/a>\u00a0(CIF),\u00a0NTSC<\/a>,\u00a0PAL<\/a>, and\u00a0SECAM<\/a>). IP cameras may differ from one another in features and functions,\u00a0video encoding<\/a>\u00a0schemes, available network protocols, and the API to be used by video management software.[9]<\/a><\/sup><\/p>\n

IP cameras are available at resolutions from 0.3 (VGA<\/a>\u00a0resolution) to 29\u00a0megapixels<\/a>.[10]<\/a><\/sup>\u00a0As in the 21st century, there has been a shift in the consumer TV business towards\u00a0high-definition<\/a>\u00a0(HD) resolutions (e.g.\u00a01080P<\/a>\u00a0(Full-HD),\u00a04K resolution<\/a>\u00a0(Ultra-HD) and\u00a016:9<\/a>\u00a0widescreen format).<\/p>\n

In order to address issues of standardization of IP video surveillance, two industry groups were formed in 2008: the Open Network Video Interface Forum (ONVIF<\/a>) and the\u00a0Physical Security Interoperability Alliance<\/a>\u00a0(PSIA). While the PSIA was founded by 20 member companies including\u00a0Honeywell<\/a>,\u00a0GE Security<\/a>\u00a0and\u00a0Cisco<\/a>, and ONVIF was founded by Axis Communications,\u00a0Bosch<\/a>\u00a0and\u00a0Sony<\/a>, each group now has numerous members. Cameras and recording hardware operating under the same standard will be able to work with each other, as each device will be communicating in the same language.[9]<\/a><\/sup><\/p>\n

Surveillance cameras can use\u00a04G<\/a>\u00a0and\u00a0WiFi<\/a>\u00a0to send pics and videos or make calls.<\/p>\n

Dashcams usually employ 4G and front 360\u00b0 cameras.<\/p>\n

Potential benefits.<\/span><\/h3>\n

IP cameras differ from previous generation analog cameras which transmitted video signals as a voltage, whereas IP camera images are sent using the transmission and security features of the\u00a0TCP\/IP<\/a>\u00a0protocol. Some advantages to this approach include:<\/p>\n
