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?
