What must designers and installers evaluate in relation to intrusion systems?

Designers and installers of intrusion detection systems must evaluate environmental factors to ensure that the system operates effectively and reliably in the intended location. Environmental factors include physical conditions and elements such as temperature, humidity, lighting, and potential obstructions that could affect the performance of sensors and other components of the security system. For example, placing motion detectors in areas with significant temperature fluctuations or near sources of interference can lead to false alarms or missed detections.

Understanding the environment allows for the tailored deployment of technology and ensures that any potential vulnerabilities created by the surrounding factors are mitigated. It also helps in selecting appropriate equipment that is rated for the specific operating conditions, thus enhancing the overall effectiveness of the intrusion detection system. Evaluating these factors is crucial in designing a system that meets security needs while maintaining functionality and reliability.
