IP video surveillance can be defined as the transmission of video utilizing open internet protocols and standards for the purpose of recording and monitoring. This should not be confused with more proprietary methodologies of transmitting video in which only the manufacturer of the camera can decode the video for the purpose of recording and/or display.
The first IP camera was released in 1996 by Axis Communications, and it utilized an embedded Linux platform internal to the camera. Axis also released documentation for their low-level API called "VAPIX" which builds on the open standards of HTTP and RTSP. This open architecture encouraged third-party software manufacturers to develop management and recording software resulting in exponential growth of the IP video surveillance market.
Some of the advantages of IP-based video surveillance include:
- Reduced system cost and added functionality due to general-purpose IP networking equipment infrastructure.
- Choice of open-platform video recording hardware and software.
- Greatly reduced system cost due to low-cost cabling in large installations (CAT5e instead of RG-58 coaxial cable).
- Flexible and seamless support for a variety of standard and multi-megapixel image resolutions beyond NTSC, PAL and SECAM.
- Transmission of commands for PTZ (pan, tilt, zoom) cameras via the same cable.
- On-camera automated alerting via email or file transfer in response to video motion detection or dry-contact alarms.
- Support for different streaming media and compression formats to relieve transmission bandwidth and data storage requirements.
- Support for new embedded intelligent video motion detection with shape recognition/counting applied to objects, people, and vehicles.
- Integration of video surveillance with other systems and functions such as access control, alarm systems, building management, traffic management, etc.
- Future-proof installations with field-upgradeable products due to the ability to upgrade camera firmware over the network.
Today there are many vendors of IP cameras and many vendors for digital video recorders and network video recorder (NVR) software. IP surveillance equipment vendors typically include both specialized digital imaging equipment manufacturers and larger manufacturers that are active in consumer, broadcast, and security video.
