Axis Exam ANVE Topic 1 Question 105 Discussion

Actual exam question for Axis's ANVE exam
Question #: 105
Topic #: 1
[All ANVE Questions]

If the subject is 3 m (10 ft) away, what is the pixel density for a 1920x1080 camera?

Show Suggested Answer Hide Answer
Suggested Answer: C

The reason why the camera is not blinded by the headlights is that an IR-pass filter is in use. This filter blocks out visible light, including the bright headlights, and allows only infrared light to pass through. This is particularly useful in nighttime surveillance scenarios where the camera can rely on infrared illumination instead of visible light, ensuring clear visibility even in the presence of bright lights like headlights.

This question is a real pixel-ache, isn't it? I'm just glad they didn't ask about the megapixel count of a potato.

I agree, the pixel density can be tricky. I would go with D) 576 px/m (192 px/ft).

Okay, let's see... 1920x1080 pixels, 3 meters away. That means the pixel density is gonna be pretty high. I'm gonna go with D, 576 px/m (192 px/ft).

I bet the answer is C. I mean, who has time to do all these calculations when you're taking a test, right? Let's just go with the lazy option.

Hmm, the question doesn't mention anything about sensor size or focal length. How are we supposed to figure this out?

Yeah, without sensor size or focal length, we can't calculate it accurately.

Wait, are we supposed to calculate the pixel density or the resolution? I'm so confused!
