Physical security IDSs can be used to detect intruders by employing electromechanical systems or volumetric systems. Which of the following provides the correct definition mapping?

i. Electromechanical systems work by detecting a change or break in a circuit.
ii. A photoelectric system detects the change in a light beam and thus can be used only in rooms with windows.
iii. A passive infrared system identifies the changes of magnetic waves in an area it is configured to monitor.
iv. An acoustical detection system uses embedded mesh installed on floors, walls, or ceilings.
v. Wave-pattern motion detectors differences in the amplitudes of the waves they monitor.
vi. A proximity detector emits a measurable magnetic field. The detector monitors this magnetic field, and an alarm sounds if the field is completed.

The depth of field is necessary to understand when choosing the correct lenses and configurations for your company’s CCTV. The depth of field refers to the portion of the environment that is in focus when shown on the monitor. Which of the following is incorrect?

Most of the CCTV cameras in use today employ light-sensitive chips called charged-coupled devices (CCDs). Which of the following is an incorrect characteristic of CCDs?

CCTVs should have some type of recording system. Digital recorders save images to ____________ and allow advanced search techniques that are not possible with __________recorders.

Sandy needs to implement the right type of fencing in an area where there is no foot traffic or observation capabilities. Sandy has decided to implement a Perimeter Intrusion Detection and Assessment System. Which of the following is not a characteristic of this type of fence?

i. It has sensors located on the wire mesh and at the base of the fence
ii. It can detect if someone attempts to cut or climb the fence
iii. It has a passive cable vibration sensor that sets off an alarm if an intrusion is detected
iv. It can cause many false alarms

Which of the following is untrue when it comes to fencing in critical areas?

Each lock type has corresponding tools that can be used to pick it (open it without the key). Which of the following is a incorrect characteristic of the types of locking picking techniques in use today?

A company should take great care in deciding which suppression agent and system is best for it. Four main types of water sprinkler systems are available: wet pipe, dry pipe, preaction, and deluge. Which of the following has an incorrect description?

There are different types of windows that can be chosen when constructing a facility. Which of the following does not provide the correct window type description?

i.Tempered – Glass is heated and then cooled suddenly to increase its integrity and strength.
ii. Acrylic – A type of plastic instead of glass. Polycarbonate acrylics are stronger than regular acrylics.
iii. Laminated – The plastic layer between two outer glass layers. The plastic layer helps increase its strength against breakage.
iv. Solar window film – Transparent film is applied to the glass to increase its strength.
v. Security film – Provides extra security by being tinted and offers extra strength due to the film’s material.

Which of the following is untrue when it comes to type K fires?
