Axis ANVE Exam - Topic 2 Question 113 Discussion

Actual exam question for Axis's ANVE exam

Question #: 113
Topic #: 2

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?

A640X480

B800 X 600

C1280 X 720

D1920 X 1080

Show Suggested Answer

Suggested Answer: C

To achieve identification at 80 pixels per face for a scene that is 2 meters (6 feet 7 inches) wide, a minimum resolution of 1280 x 720 is needed. This calculation ensures that each face captured in the frame meets the pixel density requirement for clear identification purposes.

Definitely need at least 1920x1080 for good detail!

Wait, are we really sure 80 pixels is enough?

640x480 is way too low for face ID.

800x600 might work, but not sure about clarity.

I think 1280x720 should be enough!

I think I read that higher resolutions help with clarity, especially in crowded areas. Maybe 1920x1080 is overkill, but I wouldn't want to miss any details.

I practiced a similar question where we had to determine resolution based on distance and face size. I feel like 1280x720 might be the right choice here, but I’m not completely confident.

I’m not entirely sure, but I think 80 pixels per face means we need to consider how many faces we might see at once. Could it be that 640x480 isn't enough?

I remember something about pixel density and how it relates to the size of the scene. I think we need to calculate how many pixels we need across the width.

This question is making me a bit nervous, but I'll give it my best shot. I just need to remember the formula for calculating the required resolution.

I'm pretty confident I can solve this. I just need to do some quick math to figure out the minimum resolution.

Okay, I think I got this. I need to find the number of faces that can fit in the 2m width, then calculate the minimum resolution needed to get 80 pixels per face.

Hmm, I'm a bit confused on how to approach this. Do I need to calculate the number of faces that would fit in the 2m width and then determine the resolution?

This seems straightforward, I just need to figure out the minimum resolution needed to get 80 pixels per face given the scene width.

Ah, the old camera resolution conundrum. I'm going with B) 800 x 600 – it's a classic and should do the trick. Plus, it leaves room in the budget for some snacks, am I right, folks?

I agree with Brett, D) 1920 X 1080 makes sense for clear identification.

Oof, this one's a toughie. But if I'm doing the math right, I think D) 1920 x 1080 is the safest bet. Can't be too careful with those convenience store shenanigans, ya know?

Hmm, let's see. With a scene width of 2 meters and a required resolution of 80 pixels per face, I'd say C) 1280 x 720 is the way to go. Gotta make sure we can identify those shoplifters, am I right?
