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-59 coaxial cable).
- Ability to use Power over Ethernet allowing for one cable to handle power and data.
- Flexible and seamless support for a variety of standard and multi-megapixel image resolutions way 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.
Intelligent Video Systems
Now a days, tremendous amounts of video is being recorded, yet never watched or reviewed, due to lack of time. This results in events and activities being missed, and suspicious behavior is not noticed in time to prevent incidents. This has led to the development of Intelligent Video.
Examples of video analytics applications include: counting the number of pedestrians entering a door or geographic region, determining the location, speed and direction of travel, identifying suspicious movement of people or assets, license plate identification or evaluating how long a package has been left in an area.
- Enables an automatic alert system
- Intelligence learns Background and provides filters
- Solves sensitivity problem but object differentiation is rudimentary
- Solves object differentiation to reduce false alarms
- Recognizes interaction of multiple object behaviors
