NEW QUESTION # 113
What is the primary reason for using a multisensor panoramic camera versus a single-sensor panoramic camera?
- A. To have a wider field of view
- B. To get a lower average bitrate
- C. To get higher pixel density
- D. To capture 3D video of the scene
Answer: C
Explanation:
The primary reason for using a multisensor panoramic camera versus a single-sensor panoramic camera is to achieve higher pixel density. Multisensor cameras combine images from multiple sensors to create a high-resolution, detailed panoramic view. This approach provides superior image quality and clarity, especially in large areas where high detail is needed. Axis product literature emphasizes the advantage of higher pixel density in multisensor cameras for capturing detailed, wide-area surveillance images.

NEW QUESTION # 118
PoE class 3 corresponds to what power level at the PSE?
- A. 4.0 W
- B. 7.0 W
- C. 30 W
- D. 15.4 W
Answer: D
Explanation:
PoE (Power over Ethernet) Class 3 corresponds to a power level of 15.4 W at the Power Sourcing Equipment (PSE). This classification allows the delivery of up to 15.4 W of power over standard Ethernet cables to devices such as IP cameras and VoIP phones. This information is based on the IEEE 802.3af standard, which defines the power levels for different PoE classes. Axis Communications' documentation on PoE standards confirms this power level for Class 3.
NEW QUESTION # 119
What is a benefit of utilizing external IR illumination with 940 nm?
- A. It has a deterring effect on intruders
- B. It is easy to align with the camera
- C. It provides covert surveillance
- D. It enables full color images
Answer: C
Explanation:
Utilizing external IR illumination with 940 nm provides the benefit of covert surveillance. IR light at 940 nm is almost invisible to the human eye, making it ideal for discreet monitoring without drawing attention to the presence of the camera. This allows for effective surveillance while remaining undetected by intruders. Axis Communications' product documentation on IR illumination confirms this advantage of 940 nm IR light.
NEW QUESTION # 120
In a network surveillance installation, the purpose of a switch is to
- A. Forward the video stream to the correct receiver within a network.
- B. Disconnect malfunctioning cameras from the network.
- C. Disconnect devices with invalid IP addresses from the network.
- D. Forward the video stream between networks.
Answer: A
Explanation:
In a network surveillance installation, the primary purpose of a switch is to forward the video stream to the correct receiver within a network. This functionality ensures that the video data captured by cameras is correctly directed to the appropriate storage device, monitoring station, or viewing client within the local network. Switches operate at the data link layer (Layer 2) of the OSI model and utilize MAC addresses to ensure that data packets reach their intended destination efficiently.

Answer: A,C
NEW QUESTION # 122
Which statements apply to audio in an IP-based video system? (Select two)
- A. Audio and video are transmitted to the viewer over the same IP network
- B. Simplex mode allows two-way audio but only in one direction at a time
- C. Audio travels over the IP network through separate shielded cables
- D. The quality of an audio stream improves with a higher compression rate
- E. Some Axis video encoders allow the use of audio with analog cameras
Answer: A,E
Explanation:
In an IP-based video system, audio can be transmitted alongside video over the same network, allowing for integrated audio-video surveillance. This enables the simultaneous monitoring of both audio and visual data, enhancing situational awareness. Additionally, some Axis video encoders support audio functionality with analog cameras, allowing these older devices to be integrated into modern IP-based systems and take advantage of audio capabilities. Axis documentation highlights these features, emphasizing the seamless integration of audio and video in IP surveillance solutions and the extended functionality provided by video encoders.
NEW QUESTION # 123
An integrator receives a specification for surveillance cameras for a large project, where the requirements are impossible to live up to. Which of the key numbers below would have to change in order to find a camera to fill the demands?
- A. 1080pHD resolution
- B. 60 fps
- C. Face recognition at 70 m (230 ft)
- D. 160 dB dynamic range
Answer: C
Explanation:
Among the given options, the requirement for face recognition at 70 meters (230 feet) is the most demanding and often unrealistic for most surveillance cameras. Current camera technology, even with high resolution and frame rates, typically cannot achieve reliable face recognition at such a long distance. Therefore, option D is the correct answer. For more detailed information, refer to Axis Communications' specifications on camera capabilities and face recognition technologies.
NEW QUESTION # 124
An analog system that should be upgraded to IP using encoders must have the end of the analog signal terminated. How many Ohm () should that be?
- A. 0
- B. 1
- C. 2
- D. 3
Answer: D
Explanation:
When upgrading an analog system to IP using encoders, the end of the analog signal must be terminated with a
75 resistor. This standard impedance ensures proper signal transmission and prevents signal reflections that can degrade the video quality. Terminating the signal correctly is crucial for maintaining the integrity of the video feed in an analog to IP conversion. For more information, refer to Axis Communications' technical documentation on analog to IP conversion and signal termination.
