Axis ANVE Exam - Topic 3 Question 115 Discussion

Actual exam question for Axis's ANVE exam

Question #: 115
Topic #: 3

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?

A1024x768

B1280x720

C1920x1024

D800 x 600

Show Suggested Answer

Suggested Answer: B

To identify people with 80 pixels per face in a hallway that is 2.5 meters wide, a minimum resolution of 1280x720 (720p) is needed. This resolution ensures sufficient pixel density to capture detailed facial features necessary for identification purposes. Given the width of the hallway and the required pixel density, 720p provides the necessary coverage and detail.

Surprised that 1024x768 is even an option here.

800x600? No way, that's way too low!

I think 1280x720 should be enough for face recognition.

Definitely not, you need at least 1920x1024 for clarity.

I agree, 1920x1024 seems like the best choice.

I’m pretty sure 800x600 is too low for identifying faces, but I can't recall if 1024x768 would be enough.

I feel like 1920x1024 could be overkill, but I guess it might be necessary to ensure clear identification.

I think we practiced a similar question where we had to determine resolution based on distance and width. I might lean towards 1280x720, but I'm not completely confident.

I remember something about pixel density and how it affects face recognition, but I'm not sure how to calculate the exact resolution needed.

This seems like a tricky one, but I think I can tackle it. I'll need to do some calculations to determine the minimum resolution that meets the customer's requirements.

Alright, I think I've got a strategy. I'll need to figure out the pixel density required for 80 pixels per face, then calculate the minimum resolution based on the hallway width. Let's see if I can work this out.

I'm a bit confused on how to approach this. Do I need to calculate the pixel density or something? I'm not sure where to start.

Okay, let me think this through. The width of the hallway is 2.5 m, and we need 80 pixels per face. I wonder how that translates to the minimum resolution needed.

Hmm, this seems straightforward. I just need to figure out the minimum resolution required to get 80 pixels per face in a 2.5 m wide hallway.

I think D) 800 x 600 is too low of a resolution for identifying people, so it's not the right answer.

I agree with Arlene, because 1280x720 would provide enough resolution to identify people clearly.

Ooh, this is a tricky one. I'm leaning towards C) 1920x1024, but I better double-check the calculations just to be sure.

Ha! I bet the installer wishes they could just use a smartphone camera. That would be so much easier than worrying about resolutions and stuff.

I'm not sure about this one. The hallway dimensions make me think D) 800 x 600 might be the right answer, but I could be wrong.
