What type of electronic sensor is required to detect intrusions at openings in nuclear facilities?

Point detection sensors are designed specifically to monitor and detect intrusions at defined locations or openings, making them an ideal choice for securing sensitive areas, such as those found in nuclear facilities. These sensors can be placed at critical points like doors, windows, and other entryways to promptly alert security personnel of unauthorized access.

The effectiveness of point detection sensors lies in their ability to provide a precise response to disturbances or breaches at specific locations, ensuring that any intrusion is quickly identified. This is crucial in environments where security is paramount, as it allows for immediate response to potential threats.

In contrast, while motion detection sensors monitor movement within a broader area, they may not pinpoint the precise entry point of an intrusion. Infrared sensors detect changes in heat signatures but can be subject to environmental interferences. Pressure sensors measure weight or force but are not typically used for detecting unauthorized access at openings. Hence, point detection sensors are the most appropriate technology for the context of securing nuclear facilities effectively.
