The Physical Security Interoperability Alliance (PSIA) is a global consortium of more than 65 physical security manufacturers and systems integrators focused on promoting interoperability of IP-enabled security devices and systems across the physical security ecosystem as well as enterprise and building automation systems.
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).
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. [158] IP cameras are considered part of the Internet of things ( IoT ) and have many of the same benefits and security risks as other IP-enabled devices. [ 159 ]
In May 2017, seven series of Hikvision cameras were affected by an improper authentication vulnerability which, if exploited, could allow "a malicious attacker [to] escalat[e] his or her privileges or assum[e] the identity of an authenticated user and [obtain] sensitive data," according to the U.S. Cybersecurity and Infrastructure Security Agency.
Wireless security cameras function best when there is a clear line of sight between the camera(s) and the receiver. If digital wireless cameras are outdoors and have a clear line of sight, they typically have a range between 250 and 450 feet. If located indoors, the range can be limited to 100 to 150 feet.
A webcam is a video camera which is designed to record or stream to a computer or computer network. They are primarily used in video telephony , live streaming and social media , and security . Webcams can be built-in computer hardware or peripheral devices , and are commonly connected to a device using USB or wireless protocol .
The vulnerability had been activated on cameras within the Fortune 500 company's network, and the data trafficked to China through the company's firewall. [72] Using a web browser, the vulnerability allowed unauthorized people to remotely download a device's database of usernames and password hashes and subsequently gain access to it.
The Real-Time Streaming Protocol (RTSP) is an application-level network protocol designed for multiplexing and packetizing multimedia transport streams (such as interactive media, video and audio) over a suitable transport protocol.
