security systems realize convenience and peace of mind through sensing, connectivity, and user interface technologies. In the context of building automation, security systems are composed of two constituent elements. They are

1. Monitoring Systems
2. Crime Prevention Systems
3. Monitoring Systems: -Monitoring systems may include motion sensors for ingress monitoring and fire detectors, carbon monoxide detectors, and the like to monitor for emergencies within the building. The monitored information is sent via the network to a supervisor in the form of emergency signals and images. This information can also be stored and managed on a secure data server if needed.
4. Crime Prevention Systems: -Crime prevention systems may incorporate sensors such as door open-close detectors and glass break detectors to detect emergencies as well as ingress and egress management functions to enforce entrance and exit regulations and keep logs of those entering and leaving. They control the entrance and exit of persons to and from the building in conjunction with the information from the monitoring systems.

Via the network, the large volumes of data making up the security logs, operation logs, and entrance and exit logs from the monitoring and crime prevention systems are tracked on security monitoring PCs and stored and managed on secure data servers. This information may also be linked via a network to other building automation systems (air conditioning systems, lighting systems, etc.) to enable more efficient building security management.
