When using an external IR illuminator, what can happen if the beam angle is significantly narrower than the field of view?

AFocus must be set manually

BHeat can distort the image

CThe exposure may be uneven

DThe backlight can increase

Show Suggested Answer

Suggested Answer: C

When using an external IR illuminator with a beam angle significantly narrower than the field of view, the exposure may be uneven. This can result in parts of the image being overexposed (too bright) while other parts remain underexposed (too dark). Ensuring that the beam angle of the IR illuminator matches the field of view of the camera is essential for achieving uniform illumination across the entire surveillance area.

Wait, is the IR illuminator secretly a heat lamp in disguise? B is the hottest pick for sure!

The backlight increasing? What is this, a disco party? D is clearly the wrong answer.

Hmm, if the beam is too focused, I wonder if you'd have to manually adjust the focus. A could be the right choice here.

Ooh, I bet the heat from the narrower beam would totally distort the image! B seems like the way to go.

It's important to consider the beam angle to avoid any distortion in the image.

I believe the correct answer is C) The exposure may be uneven because the light won't cover the entire field of view.
