Question 8

An installer needs a camera to monitor a hallway in an office complex. The hallway is 2.5 m (8 ft 2 in) wide. The customer wants to be able to identify people (80 pixels per face). What is the minimum resolution needed to meet this requirement?
A) 1024x768
B) 1280x720
C) 1920x1024
D) 800 x 600

Accepted Answer

To find the minimum resolution needed, we need to calculate the number of pixels needed to cover the hallway width. 
2.5 m = 8.2 ft
Assuming a person's face occupies half the width of the hallway, the face would occupy 4.1 ft or 49.2 inches. 
To get 80 pixels per inch, we need a resolution of 80 x 49.2 = 3936 pixels
This resolution can be achieved with a resolution of 1280 x 720 (921,600 pixels) or higher, so the best answer is B, 1280 x720.

C) The ONVIF API is Axis' own API which supports the latest Axis camera capabilities
D) The VAPIX® API is Axis' own API which supports the latest Axis camera capabilities

Accepted Answer

The statement "The VAPIX® API is Axis' own API which supports the latest Axis camera capabilities" is true. The ONVIF API is a standard protocol for managing video and audio configuration in IP surveillance systems, developed by the ONVIF (Open Network Video Interface Forum) organization. However, while Axis cameras support ONVIF, it is not Axis' own API.

Question 11

IEEE 802.1 X is a security feature that
A) Applies end-to-end encryption between the camera and the server over the internet, ensuring that other users on the network cannot eavesdrop on the surveillance video.
B) Only gives approved devices access to the network, making it impossible to disconnect a camera and connect other equipment to eavesdrop on the network.
C) Disables port forwarding, making it impossible for users outside the local network to get access to the surveillance video.
D) Uses a cryptographic signature to ensure the integrity of the address tables used by the router, making it impossible for malicious users to redirect the surveillance video to unauthorized recipients.

Accepted Answer

IEEE 802.1X is an authentication protocol that provides port-based access control. It ensures that only approved devices are allowed access to the network, and unauthorized devices are prevented from connecting. This feature helps prevent eavesdropping on the network. However, it does not provide encryption, disable port forwarding, or ensure address table integrity.

Question 17

In a network surveillance installation, the purpose of a switch is to
A) Forward the video stream between networks.
B) Forward the video stream to the correct receiver within a network.
C) Disconnect malfunctioning cameras from the network.
D) Disconnect devices with invalid IP addresses from the network.

Accepted Answer

The purpose of a switch in a network surveillance installation is to route video streams to the correct receiver within a network. Switches are used to create local area networks (LANs), which allow multiple devices to connect and communicate with each other. In a surveillance network, cameras and recorders are connected to the LAN via a switch, which routes the video streams to the correct destination. Switches do not typically disconnect malfunctioning cameras or devices with invalid IP addresses from the network.

Question 18

An installer wants to be sure that the AXIS P3347 always delivers full frame rate (30 fps) even in darker conditions. Which of the following options should be used?
A) Set priority to frame rate
B) Set maximum shutter time to 1/30 s
C) Set the capture mode to 3 megapixel
D) Set the Group of Video (GOV) length to 30

Accepted Answer

Setting the maximum shutter time to 1/30 s will ensure that the camera always delivers full frame rate even in darker conditions by adjusting the exposure time of each frame to match the desired frame rate. Setting priority to frame rate or capture mode to 3 megapixel may improve image quality but will not guarantee full frame rate in darker conditions. Setting the Group of Video (GOV) length to 30 determines the frequency of key frames in the video stream and has no effect on frame rate in low light conditions.

Question 19

When dealing with a complicated lighting scenario, such as a camera inside looking out through bright windows, which camera would best adapt to the scene to provide the highest image detail?
A) AXIS M3204
B) AXIS P3304

D) AXIS Q1604

Accepted Answer

The AXIS Q1604 has wide dynamic range (WDR) technology and advanced image processing, which allow for clear and detailed images even in complex lighting scenarios such as bright windows.

Question 20

The advantage of using multicast in the network is that
A) Many cameras can share the same network connection.
B) The video stream reaches every computer in the network simultaneously.
C) The video stream only needs to be sent once, even though there are multiple viewers.
D) The video stream is rerouted in case of network dropout.

Accepted Answer

Using multicast allows for efficient distribution of a video stream because it only needs to be sent once, even though there may be multiple viewers. This reduces network congestion and is more scalable than sending individual streams to each viewer.
