Question 1

Looking at the picture below, which setting would best address the blurring that's occurring with faster moving objects? 
A) Increase image brightness
B) Adjust the exposure settings
C) Uncheck backlight compensation
D) Increase image contrast

Accepted Answer

Blurring with faster moving objects is often caused by a slow shutter speed. Adjusting the exposure settings, specifically increasing the shutter speed, can help reduce the blurring. Increasing image brightness or contrast would not directly address the blurring issue, and unchecking backlight compensation is unrelated to this issue.

Question 2

The purpose of a DNS server is to
A) Allocate IP addresses to devices within a network.
B) Allocate MAC addresses to devices within a network.
C) Translate host names such as www.axis.com to IP addresses.
D) Translate host names such as www.axis.com to MAC addresses.

Accepted Answer

The purpose of a DNS server is to translate host names, which are easier for humans to remember, to their corresponding IP addresses, which are used by computers to communicate on a network.

Question 3

In a dark indoor environment one single Axis illuminator is available. At a distance of 1 m (3 ft 3 in) away from the illuminator the light intensity is 1024 lux. At what distance from the light source will the light intensity be 256 lux?
A) 2 m (6 ft 7 in)
B) 4m{13 ft 1 in)
C) 8 m (26 ft 3 in)
D) 16 m (52 ft 6 in)

Accepted Answer

The intensity of light decreases with the square of the distance from the source. If the intensity is 1024 lux at 1 m, it will be 256 lux at 2 m, since (1/2)^2 = 1/4, and 1024/4 = 256.

Question 4

Which statement is true for broadcast network traffic?
A) Broadcast is designed to enable optimized video transmission, since it tolerates network dropouts
B) Broadcast is not practical for network video transmission, since packets are transmitted to every device on the network
C) Broadcast is a method for sending video to many recipients over the internet even though their bandwidths vary
D) Broadcast data packet length is longer than normal Ethernet packets, to accommodate a full video frame

Accepted Answer

Broadcast network traffic sends packets to every device on the network, which can cause congestion and slow down the network. This makes it impractical for video transmission.

Question 5

Which security features are provided through a managed switch?
A) IEEE 802.1 X port-based authentication and HTTPS encryption
B) IP subnets and VLANs
C) HTTPS encryption and IP subnets
D) IEEE 802.1 X port-based authentication and VLANs

Accepted Answer

A managed switch provides IEEE 802.1 X port-based authentication, which allows only authorized devices to access the network, and VLANs, which segregate network traffic to enhance security and performance. HTTPS encryption may also be provided, but it is not a primary security feature of a managed switch. Similarly, IP subnets may be utilized on a managed switch but are not a primary security feature.

Question 6

A camera is positioned where backlighting is a problem. What would be the preferred action? 
A) Use a lens with a polarized filter
B) Axis P-iris technology will solve your problem
C) Increase the shutter speed to more than 1 /100 s

Question 7

Image flickering is caused by
A) IR light
B) White light
C) Lack of light
D) Fluorescent light

Accepted Answer

Image flickering is commonly caused by fluorescent light because of the way they work. Fluorescent lights flicker at a very high rate (typically 60 Hz) which can cause visible flicker on cameras or displays that are capturing or showing the light source.

Question 8

What is the difference between a zoom lens and a varifocal lens?
A) There is no difference
B) A zoom lens maintains focus when changing field of view
C) A zoom lens always has automatic focus
D) A varifocal lens has a longer field of view

Accepted Answer

The main difference between a zoom lens and a varifocal lens is that a zoom lens can maintain focus when changing the field of view, whereas a varifocal lens requires manual focus adjustment. Therefore, B is the best choice as it correctly identifies this difference.

Question 9

When using HTTPS on Axis products, true security is implemented after the
A) 64 character password is in place.
B) 256 character password is in place.
C) MAC address filtering is activated.
D) Signed certificate is installed.

Accepted Answer

True security with HTTPS on Axis products is implemented after a signed certificate is installed. This ensures that the communication between the device and the client is encrypted and cannot be intercepted by third parties. Passwords and MAC address filtering can provide additional security measures, but they are not the key factor for implementing true security with HTTPS.

Question 11

A convenience store needs a camera to cover the entrance. Identification is needed at 80 pixels per face. Given that the scene is 2 m (6 ft 7 in) wide, which of these resolutions is the minimum one needed?
A) 640X480
B) 800 X 600
C) 1280 X 720
D) 1920 X 1080

Accepted Answer

To calculate the minimum resolution needed, we need to determine the number of pixels per meter. 
2 meters = 200 cm = 2000 mm 
80 pixels per face * 2 faces (front and side) = 160 pixels per meter 
Therefore, the minimum resolution needed is: 160 pixels/meter * 2 meters = 320 pixels wide 
Out of the given options, only C has a width of 1280 pixels, which is more than the minimum needed (1280 > 320). Therefore, option C is the best choice.

Question 12

When using the AXIS Design Tool, what is the most important message to bring to your end user?
A) That the numbers calculated are always conservative
B) That using RAID configurations is always recommended

A) 850 nm
B) 950 nm
C) 1140 nm
D) 1350 nm

Accepted Answer

Generally, most Day & Night cameras are sensitive to 850 nm wavelength for low light operations. This is because 850 nm is the most commonly used wavelength for IR illuminators that are used in conjunction with Day & Night cameras.

Question 15

What is the benefit of deinterlacing the video in a video encoder?
A) It gives the encoded video a higher frame rate compared to the analog input video
B) It reduces the tearing effects when there is movement between two fields in one frame
C) It enhances the dynamic range between two fields in one frame
D) It decreases the bandwidth needed to transmit the compressed video

Accepted Answer

Deinterlacing reduces the tearing effect that can occur when there is movement between two fields in one frame. It does not directly impact frame rate, dynamic range or bandwidth usage.

Question 16

In clear weather. Axis specifies, in accordance with Johnson's criteria, an AXIS Q1921 with a 60 mm lens to have detection range of 1200 m (3900 ft) for a person. Based on this estimation which of the following is true?
A) An analysis or analytic software is able to detect a person in 1200 m distance with 90% probability
B) A human observer is able to detect a person in 1200 m distance with 50% probability
C) A human observer can discern a person versus a car in 1200 m distance with 90% probability
D) An analysis or analytic software is able to discern a person versus a car in 1200 m distance with 50% probability

Accepted Answer

According to Johnson's criteria, the detection range of an AXIS Q1921 with a 60 mm lens is 1200 m for a person. This means that a human observer is able to detect a person in 1200 m distance with 50% probability, not with 90% probability (choice A) or discern a person versus a car with 90% probability (choice C). The question does not mention anything about software being used to detect or discern objects, so choices A and D can be eliminated.
