Hikvision IR Bullet Camera Shootout

By Ethan Ace, Published Jan 08, 2018, 12:06pm EST

Hikvision's widely used Value Plus line claims 30m/~98' IR illumination range, on multiple lens options ranging from wide angle (100°+) to telephoto (25°).

We bought and tested 4 Hikvision DS-2CD2025FWD-I bullet cameras against each other:

  • 2.8mm/108° AoV
  • 4mm/86.4° AoV
  • 6mm/52° AoV
  • 8mm/40° AoV

The image below from the IPVM Calculator shows the angle of view (and specified IR range) for each lens option:

Testing indoors and outdoors, we examined:

  • How does IR illumination pattern differ across models?
  • Which models, if any, offer more even coverage for their angle of view?
  • What advantages in details are there when using long lens options?
  • How does performance differ outdoors versus smaller, reflective areas indoors?

Are these crops?  The AOV seems pretty much the same.

Yes, as we explain above it, that's an image from the 2.8mm camera, showing how the illuminator of each of them varies. So it's easy to see it narrow.

But fair point, we should put in a full field of view from each camera for clarity. We'll mark all that up better.

You’re right, you do say that, it’s clear now that I read it again.

btw, how much ambient light is present there?

do you think the beam angle would be easier to discern if it were darker?

That was outside, with the lights off, and about 0.05-0.1lx, depending on distance. The pattern might be more visible if it were darker, but it's pretty hard to find an outdoor scene that's much darker.

Those are the ones of IR, not the lens.

Since they didn't have pics of actual coverage differences between models, they wanted to make it easier to compare the other aspects I'm guessing. And use the IPVM calculator instead.
