What are the two main types of cable used for transmitting video signals?
-
Unbalanced (Coaxial)
-
Singlemode
-
Balanced (twisted-pair)
-
Multimode
Correct Answer(s)
A. Unbalanced (Coaxial)
A. Balanced (twisted-pair)Explanation
The two main types of cable used for transmitting video signals are unbalanced (coaxial) and balanced (twisted-pair). Unbalanced cables, such as coaxial cables, use a single conductor surrounded by a shield to carry the signal. They are commonly used for shorter distances and can transmit both analog and digital video signals. On the other hand, balanced cables, like twisted-pair cables, use two conductors twisted together to carry the signal. They are more resistant to interference and are commonly used for longer distances, especially in professional audio and video applications.Rate this question:

The Frame rate is based on the U.S. power standard of ______ hertz?
-
30 Hz
-
40 Hz
-
60 Hz
-
50 Hz
Correct Answer
A. 60 HzExplanation
The frame rate is based on the U.S. power standard of 60 Hz. This means that the screen refreshes 60 times per second, resulting in smoother motion and a more immersive viewing experience. The higher the frame rate, the smoother the motion appears to the human eye.Rate this question:

What is the normal frame rate for an analog camera?
-
20 frames per second
-
30 frames per second
-
40 frames per second
-
60 frames per second
Correct Answer
A. 30 frames per secondExplanation
An analog camera typically records video at a frame rate of 30 frames per second. This frame rate is considered the standard for analog cameras as it provides smooth and fluid motion in the recorded video. Higher frame rates, such as 60 frames per second, are commonly used in digital cameras and provide even smoother motion, but analog cameras generally operate at 30 frames per second.Rate this question:

Direct hold and Shear locks are what type of locks?
-
Bored locks
-
Rim locks
-
Megnetic locks
-
Vertical rod locks
Correct Answer
A. Megnetic locksExplanation
Direct hold and shear locks are types of magnetic locks. These locks use an electromagnetic force to secure doors, making them highly secure and commonly used in commercial and high-security settings. They are often installed on glass doors or doors with metal frames, and they provide a strong holding force to prevent unauthorized entry.Rate this question:

What are some of the primary applications of CCTV?
-
Investigation
-
Prosecution
-
Deterrence
-
Observaion
-
Intrusion detection
Correct Answer(s)
A. Investigation
A. Prosecution
A. Deterrence
A. Observaion
A. Intrusion detectionExplanation
CCTV, or closed-circuit television, is widely used for various purposes. One primary application is investigation, as CCTV footage can be reviewed to gather evidence or identify suspects in criminal cases. Prosecution is another application, as the recorded footage can be presented as evidence in court. CCTV also serves as a deterrent, as the presence of cameras can discourage potential criminals. Additionally, it is used for observation purposes, such as monitoring public areas or traffic. Lastly, CCTV is utilized for intrusion detection, allowing for the immediate identification of unauthorized access or suspicious activities.Rate this question:

The components of a fire consist of:
-
Smoke
-
Heat
-
Light radiation
-
Match
-
Lighter
Correct Answer(s)
A. Smoke
A. Heat
A. Light radiationExplanation
The components of a fire consist of smoke, heat, and light radiation. Smoke is produced when materials burn and release particles into the air. Heat is generated through the combustion process, providing the energy necessary for a fire to sustain itself. Light radiation is emitted as a result of the high temperatures reached during a fire. However, the match and lighter mentioned in the question are not components of a fire, but rather tools used to initiate the combustion process.Rate this question:

The distance that a CCTV signal may be run is determined by the:
-
Signal strengty at the source (e.g., camera)
-
Required signal strengty at the receiving end (e.g., monitor)
-
Signal loss over the distance of the cable run
-
Location
-
Cost
Correct Answer(s)
A. Signal strengty at the source (e.g., camera)
A. Required signal strengty at the receiving end (e.g., monitor)
A. Signal loss over the distance of the cable runExplanation
The distance that a CCTV signal may be run is determined by the signal strength at the source (e.g., camera), the required signal strength at the receiving end (e.g., monitor), and the signal loss over the distance of the cable run. These factors play a crucial role in determining the quality and reliability of the CCTV signal transmission. The stronger the signal at the source and the higher the required signal strength at the receiving end, the shorter the distance the signal can be transmitted effectively. Additionally, the signal loss over the distance of the cable run also affects the maximum distance the CCTV signal can be transmitted without significant degradation.Rate this question:

-
Public
-
Semi-public
-
Semi-private
-
Private
Correct Answer(s)
A. Public
A. Semi-public
A. Semi-private
A. PrivateExplanation
Crime Prevention through Environmental Design (CPTED) spaces are categorized into four types: public, semi-public, semi-private, and private. Public spaces are accessible to everyone and are often open and highly visible, such as parks or plazas. Semi-public spaces have limited access and are usually associated with specific organizations or groups, like office buildings or schools. Semi-private spaces have controlled access and are typically associated with residential areas, like apartment complexes or gated communities. Private spaces have restricted access and are exclusively for the use of individuals or specific groups, like private homes or offices.Rate this question:
