Summary of Differences

• Lens Size & View:

  • 2.8mm model offers a wider field of view (better for broad-area monitoring).

  • 4.0mm model offers longer DORI range (better for distance-focused viewing).

Choose based on your monitoring needs:

• Choose 2.8mm for wide coverage (e.g., room or entrance).

• Choose 4.0mm for monitoring distant targets more clearly (e.g., gate or hallway).
