In this video you will learn about physical security controls such as: bollards & barricades, access control vestibules, badges, alarms, signage, cameras, closed-circuit television, industrial camouflage, security personnel, & security locks.
Bollards/Barricades
A bollard is a sturdy, short, vertical post that is installed to control road traffic & prevent automotive vehicles from colliding or crashing into pedestrians & structures, whether intentional from ram-raids and vehicle-ramming attacks, or unintentional losses of control.
A barricade is any object or structure that creates a barrier or obstacle to control, block passage or force the flow of traffic in the desired direction. Barricades also include temporary traffic barricades designed with the goal of dissuading passage into a protected or hazardous area or large slabs of cement whose goal is to prevent forcible passage by a vehicle.
Access Control Vestibules (Mantrap)
A mantrap is a physical security access control system consisting of a small space with two sets of interlocking doors, such that the first set of doors must close before the second set opens. In a manual mantrap, a guard locks and unlocks each door in sequence. An intercom and/or video camera are often used to allow the guard to control the trap from a remote location. In an automatic mantrap, identification may be required for each door, sometimes even possibly different measures for each door. For example, a key may open the first door, but a personal identification number entered on a number pad opens the second door. Other methods of opening doors include proximity cards or biometric devices such as fingerprint readers or iris recognition scans. Overall, mantraps basically slows down a person’s entry process to prevent unauthorized entry into an area.
Badges
An access badge is a credential used to gain entry to an area having automated access control entry points. Entry points may be doors, turnstiles, parking gates or other barriers. Access badges use various technologies to identify the holder of the badge to an access control system. The most common technologies are magnetic stripe, proximity, barcode, smart cards, & various biometric devices.[1]
Alarms & Signage
A security alarm is a system designed to detect intrusion, such as unauthorized entry, into a building. Security alarms used in residential, commercial, industrial, & military properties protect against burglary or property damage, as well as personal protection against intruders.
A typical security alarm system includes:[2]
Cameras
A security camera is a video camera that records people’s activities in order to detect & prevent crime.[3]
Two main features of a security camera are as follows:
Closed-Circuit Television (CCTV)
Video surveillance (also known as closed-circuit television, CCTV) is the use of video cameras to transmit a signal to a specific place, on a limited set of monitors. It differs from broadcast television in that the signal is not openly transmitted, though it may employ point-to-point, point-to-multipoint, or mesh wired or wireless links. Even though almost all video cameras fit this definition, the term is most often applied to those used for surveillance in areas that require additional security or ongoing monitoring.[4]
Industrial Camouflage
Industrial camouflage is the use of blended images where the surrounding scenery and the camouflaged structure appear as one, with the goal to deceive passersby to believe the structure is something else entirely. For example, roofs are sometimes planted with grass or with small shrubs that match their surroundings, or even trees to provide even better concealment & natural irregularity of light and shadows.[2]
Personnel
Locks
Oftentimes, the simplest forms of security are the most effective; this is often the case with locks on all network areas & equipment.
