1. Which of the following devices is primarily used to detect motion
within a protected area?
a) Access control reader
b) PIR sensor
c) Magnetic contact
d) DVR
Rationale: A PIR (Passive Infrared) sensor detects motion by
measuring changes in infrared radiation caused by moving objects,
making it ideal for monitoring areas for intruders.
2. The primary purpose of an uninterruptible power supply (UPS) in
an electronic security system is to:
a) Increase network speed
b) Provide surge protection only
, c) Maintain power during outages
d) Extend battery life of individual devices
Rationale: A UPS provides temporary backup power during outages,
ensuring continuous operation of critical security devices like alarms
and cameras.
3. What type of cable is most commonly used for high-resolution
CCTV systems?
a) Coaxial
b) Cat5e or Cat6 Ethernet
c) Fiber optic
d) RG59 only
Rationale: Modern CCTV systems often use Cat5e or Cat6 Ethernet
cables for IP cameras, supporting higher data rates and PoE (Power
over Ethernet) functionality.
4. In an access control system, what does the acronym “Wiegand”
refer to?
a) A type of keypad
b) A communication protocol
c) A motion sensor
d) A video encoder
,Rationale: Wiegand refers to a communication protocol commonly
used for transmitting data between access control readers and
controllers.
5. Which of the following is the most secure method for storing
surveillance video?
a) Local DVR only
b) Encrypted cloud storage
c) USB flash drives
d) Unencrypted network storage
Rationale: Encrypted cloud storage provides protection against
physical theft, unauthorized access, and data corruption while
allowing remote access.
6. Which type of sensor is best suited for detecting a window break?
a) PIR sensor
b) Glass break sensor
c) Magnetic contact
d) Smoke detector
Rationale: Glass break sensors detect the specific frequency of
breaking glass and trigger alarms when a window is broken.
7. The primary function of a relay in an electronic security system is
to:
, a) Store video recordings
b) Detect motion
c) Switch high-current devices
d) Encode video signals
Rationale: Relays act as electrically controlled switches, allowing low-
power control circuits to safely operate higher-power devices like
sirens or locks.
8. In video surveillance, “PTZ” stands for:
a) Passive Transmission Zoom
b) Pan-Tilt-Zoom
c) Primary Telemetry Zone
d) Photo Tracking Zoom
Rationale: PTZ cameras can pan, tilt, and zoom remotely, providing
dynamic coverage of large areas.
9. Which of the following is an example of two-factor
authentication?
a) Password only
b) Password and a fingerprint
c) Keycard only
d) Security question only
