What is the primary function of sensors used in border control?

The primary function of sensors used in border control is to detect alien traffic. These sensors are specifically designed to monitor activities along borders, identifying unauthorized crossings by individuals or groups attempting to enter a country unlawfully. By deploying a range of technologies, such as motion detectors, infrared cameras, and radar systems, border patrol agencies can quickly ascertain whether there is illegal activity taking place.

While collecting data, recording events, and providing communication are important aspects of overall border security operations, they support the main objective of detecting unauthorized entries instead of being the core function of the sensors themselves. For instance, sensors can collect data about traffic patterns or record events for later analysis, but their immediate purpose is to alert border control personnel to potential breaches in security as they happen.
