Which of the following is a factor that increases the complexity of a burglar alarm system?

The number of entry points to secure is a factor that increases the complexity of a burglar alarm system because each entry point typically requires its own set of sensors, wiring, and potentially additional monitoring. More entry points mean that there is a greater overall network of components that need to be coordinated within the system, which can lead to more complex installation requirements, troubleshooting, and maintenance.

Additionally, with a higher number of entry points, there may be increased possibilities for sensor malfunction or failures, as well as more sophisticated integration needs between various types of sensors (like motion detectors, door/window contacts, and glass break detectors) to ensure proper coverage. This complexity affects not just the technical setup of the system but also the planning and strategic considerations involved in effectively securing the premises.

Other factors such as the type of monitoring service, backup alarms, and weatherproofing also contribute to the functionality and reliability of a system, but they do not inherently complicate the overall architecture and operational integration of the alarm system in the same manner as the sheer number of entry points does.
