item appearance move to sidebar hide from wikipedia the free encyclopedia network connected digital video camera not to be confused with ip code rated camera ip camera a variety of ip cameras date invented 1996 30 years ago 1996 invented by axis communications connection ethernet wi fi an internet protocol camera or ip camera is a type of digital video camera that receives control data and sends image data via an ip network they are commonly used for surveillance but unlike analog closed circuit television cctv cameras they require no local recording device only a local area network most ip cameras are webcams but the term ip camera or netcam usually applies only to those that can be directly accessed over a network connection some ip cameras require support of a central network video recorder 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 ip camera was invented by axis communications 1 2 in 1996 history edit the first centralized ip camera the axis neteye 200 was released in 1996 by axis communications 3 although the product was advertised to be accessible from anywhere with an internet connection 4 the camera was not capable of streaming real time video and was limited to returning a single image for each request in the common intermediate format cif this limitation can be attributed to the lack of powerful integrated circuits capable of handling image processing at the time of release as a result the camera was aimed primarily at the tourism industry and was not intended to replace traditional analog cctv systems 5 6 the first decentralized ip camera was released in 1999 by mobotix the camera s linux system contained video alarm and recording management functions in 2005 the first ip camera with onboard video content analytics vca was released 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 7 with advancements in cloud infrastructure ring owned by amazon u s released its first ip camera doorbell targeted for home use in 2014 the device offered quick setup cloud based recording and motion detection the device retailed for 199 usd as of 2021 ring has sold millions of units with the success of ip cameras other companies such as nest owned by google u s released similar cloud based devices 8 standards edit previous generations of analog cctv cameras used established broadcast television formats e g cif ntsc pal and secam since 2000 there has been a shift in the consumer tv business towards high definition hd resolutions e g 1080p full hd 4k resolution ultra hd and 16 9 widescreen format 9 ip cameras may differ from one another in resolution features video encoding schemes available network protocols and the api for video management software 10 to address ip video surveillance standardization issues two industry groups formed in 2008 the open network video interface forum onvif and the physical security interoperability alliance psia psia was founded by 20 member companies including honeywell ge security and cisco onvif was founded by axis communications bosch and sony 11 each group now has numerous additional members thus cameras and recording hardware that operate under the same standard are compatible with each other 10 technology edit network cameras have been developed for both enterprise and consumer use consumer ip cameras used for home security typically send live video to a companion app on a user s device they generally connect to the internet through wi fi or an ethernet cable 12 unlike consumer ip cameras enterprise ip cameras often offer higher video resolution video analytics and are mostly accessed through http and real time streaming protocol rtsp ip cameras used to be more common in businesses rather than in homes but that is no longer the case a 2016 survey of 2 000 americans revealed 20 of them owned home security cameras this crossover to ip cameras in home use is partly due to the device s self installation ip cameras typically don t require professional installation saving time for home and business owners 13 one of the most popular abilities that consumer level home security cameras have is to view their footage via a mobile app many cameras offer features such as a wide angle lens low light or night vision capabilities and motion detection most are developed to send out notifications via an application such as when motion is detected video clips can be stored in a local device such as a micro sd card or through a cloud service 14 the market size of home security systems reached 4 8 billion in 2018 it had a compound annual growth rate of 22 4 between 2011 and 2018 15 people in countries that suffer from high crime rates particularly robbery and theft are keen to adopt home security cameras the us and china have a high implementation rate of residential security cameras 16 major key players in the home security market are nest owned by google us ring owned by amazon us and arlo owned by netgear us in the alarm security industry key players are adt us vivint us and simplisafe us the largest ip camera manufacturers are hikvision digital technology china axis communications sweden and dahua china 17 ip camera types edit depending on their functionality ip cameras are generally classified as fixed varifocal or pan tilt zoom ptz camera fixed cameras feature an immobile perspective on the subject whereas varifocal cameras have the ability to remotely adjust the zoom of the image in addition ptz cameras have the ability to direct the camera assembly in any direction remotely this can be used to track motion or manually adjust the monitoring area ip cameras can be designed for indoor or outdoor use outdoor cameras are often rated ip65 ip67 in order to withstand outdoor conditions ip cameras can offer a variety of digital imaging technologies such as multi sensor cameras panoramic cameras and thermal imaging cameras citation needed cloud and local storage edit some camera manufacturers offer cloud subscriptions where users may remotely view and download recent video clips by paying recurring subscription fees cloud subscription plans typically come with several days of looping storage and the videos will be overwritten beyond this duration 18 some cameras include a micro sd card slot so users can store videos locally most ip cameras can be programmed to overwrite old video once the storage medium is full accessing the video on the camera can normally be done via a direct network connection to the device considerations edit an axis 214 ptz camera potential benefits edit previous generation cameras transmitted analog video signals ip cameras send images digitally using the transmission and security features of the tcp ip protocol advantages to this approach include two way audio via a single network cable allows users to listen to and speak to the subject of the video e g a clerk assisting a customer through step by step instructions use of a wi fi or wireless network 19 distributed artificial intelligence dai as the camera can contain video analytics that analyze images 20 secure data transmission through encryption and authentication methods such as wpa or wpa2 tkip or aes remote accessibility that lets users view live video from any device with sufficient access privileges 21 power over ethernet poe to supply power through the ethernet cable and operate without a dedicated power supply better image resolution typically four times the resolution of an analog camera 22 artificial intelligence and internet privacy edit the american civil liberties union aclu has expressed privacy concerns if ai is widely practiced ai is capable of tracking movements and studying behaviors moreover ai can also recognize emotions and further predict patterns of movement 23 facial recognition system edit facial recognition identifies a human face by analyzing facial features from a picture or video an example of biometrics if a camera allows users to set up a database that includes family members and close friends the system may distinguish whether someone exists in the database if the camera is capable of providing accurate facial recognition it can tell if the person it detects is authorized in the database the detection of unauthorized persons may prompt the owner to call law enforcement 24 the footage can be used as a means of identifying and apprehending offenders potential concerns edit concerns include privacy concerns 25 average higher purchase cost per camera 26 security can be compromised by insecure credentials given that the camera can be accessed independently of a video recorder public internet connection video can be complicated to set up 27 or using the peer to peer p2p network data storage capacity concerns 28 high video quality has the potential to overload networks 29 hacking edit if video is transmitted over the public internet rather than a private network or intranet cctv devices potentially become open to a wider audience including hackers malicious actors can access private cctv systems to disable manipulate or observe security measures as well as gain further access to the private network it s connected to often referred to colloquially as pivoting this risk can be mitigated by securing the network via firewall rules designed to restrict access to the device and by keeping software and firmware up to date in 2012 users of 4chan hacked into thousands of streaming personal ip cameras by exploiting a vulnerability in some models of trendnet home security cameras 30 in 2014 it was reported that the site insecam indexed 73 011 locations worldwide with security cameras that used default usernames and passwords and were therefore unprotected 31 automated services like shodan io constantly scan residential and commercial ip blocks to automatically detect and catalog open ports and services including those commonly used for ip cameras 32 see also edit closed circuit television camera dashcam remote camera references edit interview with martin gren inventor of the network camera sdm magazine
