Building Security Systems

Renesas building security systems realize convenience and peace of mind through sensing, connectivity and user interface technologies.


In the context of building automation, a security systems is composed of two constituent elements. Figure below is a conceptual diagram. The first is a monitoring systems that oversees what is going on in and around the building by means of cameras and sensors of various types. The second is a crime prevention systems that performs ingress and egress management and control based on the information from the monitoring systems.

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 security data server, if needed.

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.

Communication Networks of Security 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 security 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.

These solutions are suitable for building security systems and deliver low cost and power efficiency alongside highly accurate measurement. Using these reference boards contributes to significantly shorter development time.


Renesas connectivity solutions are available for wireless communication (BLE and Sub-GHz) and wired communication (PLC) applications. They enable customers to build networks linking devices and systems without the need to install new wiring.

User Interface

Renesas HMI solutions comprise microcontrollers incorporating exclusive touch panel sensing technology and a custom development environment that facilitates quick development of high-grade products. There are also solutions that can be used to boost legibility and ease of use with interfaces supporting video and 3D-graphics.
