Axis 01961-001 M12 16mm F1.8 Fixed Lens 4-Pack

Overview

The Axis 01961-001 is a 4-pack of M12-mount 16mm F1.8 fixed lenses, sold as a service and stocking accessory for field techs and integrators who maintain a fleet of Axis network cameras. Buying four at once covers a multi-camera install or keeps spares on the truck for lens swaps and field repairs without waiting on a single-unit reorder. The 16mm focal length is a narrow-to-normal angle of view, suited to longer sightlines — corridors, aisles, or perimeter segments — where you need more detail at distance rather than wide coverage.

Compatibility

These are M12-mount lenses, the standard board-lens interface used across Axis network cameras that accept user-replaceable optics. Confirm the specific camera model in your fleet uses an M12 lens mount and an F1.8 optical spec before ordering, since board-lens threads and back-focus tolerances are model-specific even within the same mount family. Because these ship as bare optics rather than a camera-specific kit, match the mount type and focal length to your camera's published lens spec before install.

Installation Notes

Swapping an M12 lens requires refocusing and back-focus adjustment on install — budget bench time per unit rather than treating this as a drop-in part. Handle the glass by the housing edge only; fingerprints on the element degrade low-light and IR performance immediately, which matters more on this fixed-focus part since there's no in-camera correction for a smudged lens. Work in a clean, static-safe area since the lens mounts directly to the camera's image sensor board.

Each 01961-001 lens carries a 3-year warranty, consistent with Axis's standard coverage on lens accessories — worth factoring into total cost of ownership when stocking spares for a Axis catalog of deployed cameras. For broader planning on matching optics to coverage requirements, see this lens and coverage selection guide. If you're outfitting new installs rather than just restocking spares, browse IP cameras compatible with M12 optics, and pair with appropriate network video recorders to complete the recording side of the deployment.
