AI-assisted screening can support human operators by reducing repetitive inspection tasks and prioritizing potentially high-risk images.

Computer vision is also expanding beyond baggage screening. Advanced cameras and video analytics can identify unusual activity, restricted-area access, abandoned objects, crowd anomalies, and other security events. Combining video intelligence with other detection systems can create a more comprehensive security environment.

IoT technologies are enabling detection devices to become connected components of larger security networks. Sensors and detection systems can continuously transmit operational information to centralized platforms. This connectivity supports equipment monitoring, remote configuration, predictive maintenance, and real-time alerts.

Cloud computing is contributing to centralized security management, particularly for organizations operating multiple facilities. Cloud-based platforms can consolidate data from distributed systems and provide security teams with a unified operational view. However, edge computing is also becoming important where rapid response and low latency are essential.
