Who provides security surveillance over the boundary of restricted areas or individual resources?

• A. Remote monitoring center
• B. Close-boundary sentries
• C. Patrol Interceptors
• D. Boundary Liaison Officers

Answer: (B)

Surveillance over the boundary of restricted areas is carried out by those stationed right at the edge—close-boundary sentries. Their position allows continuous visual coverage and immediate detection of any intrusion or suspicious activity as it happens, enabling rapid alerting and response. This direct, front-line presence is what provides the most effective boundary security, since they can observe things that sensors or remote centers might only notice after a delay.

Other roles support boundary security but don’t perform the ongoing, edge-of-area surveillance themselves. A remote monitoring center analyzes feeds from cameras and sensors and coordinates actions, but the actual boundary watching is done by the sentries. Patrol interceptors are mobile units that respond to incidents, not continuous perimeter surveillance. Boundary liaison officers handle coordination and communication with stakeholders, not the on-site watching of the boundary.
