Visitor entrances are required to be equipped with which of the following electronic security devices according to directive 2007 RB?

The correct answer highlights that visitor entrances must be equipped with both walk-through metal detectors and fluoroscope machines as specified in directive 2007 RB. This requirement is crucial as it enhances security protocols by ensuring that all visitors undergo thorough screening to detect any prohibited items that could pose a risk to the facility's safety.

Walk-through metal detectors serve to identify metallic objects, while fluoroscope machines offer an advanced level of scrutiny by allowing visual inspection of bags and other carry-on items without physical search. This combination of technologies promotes a secure environment and complies with the standards set forth in the directive, addressing safety concerns effectively.

Understanding the importance of these security measures helps in recognizing the need for comprehensive screening processes in correctional facilities, highlighting the balance between facilitating necessary visits and maintaining strict security controls.
