In a security system, what is a critical consideration regarding the installation location of devices?

In a security system, choosing a location to install devices involves understanding the need to cover all potential intrusion points. This consideration is fundamental because the primary goal of a security system is to detect and prevent unauthorized access to a location. Placing devices where they can effectively monitor entry points—such as doors and windows—or areas with higher likelihoods of intrusion ensures a comprehensive surveillance strategy.

Covering all potential intrusion points not only maximizes the likelihood of detecting an intruder but also helps to avoid blind spots where an intrusion could go undetected. This is critical for the overall effectiveness of the security system, as it directly impacts the ability to respond quickly to threats.

While factors such as access to local law enforcement, ease of resetting the system, and cost of installation are also important considerations, they do not have the same immediate impact on the effectiveness of intrusion detection. Cost and convenience should not compromise the strategic deployment of devices meant to secure an area. Prioritizing coverage allows a security system to function optimally in protecting against unauthorized access.
