Axis i-CS F1.5 Varifocal Lens 3.9-10mm - 02367-001

Axis 02367-001 i-CS F1.5 Varifocal Lens 3.9-10mm

The Axis 02367-001 is a precision varifocal lens engineered for IP surveillance systems requiring flexible focal-length adjustment without manual reconfiguration. The 3.9–10 mm varifocal range paired with an F1.5 maximum aperture delivers measurable performance gains in low-light and mixed-illumination deployments. The i-CS (intelligent-CS) mount automates focus, zoom, and aperture control, eliminating the focus hunting and lens drift artifacts common in manual varifocal systems.

Key Features

• 3.9–10 mm varifocal range — approximately 2.6x magnification. Balances wide situational awareness with sufficient zoom for perimeter detail capture in open surveillance zones where pan-tilt-zoom may be unavailable or uneconomical.
• F1.5 maximum aperture — transmits roughly 77% more light than typical F2.0 designs. Critical advantage for parking areas, hallways, and night-vision scenarios where shutter speed and ISO trade-offs degrade detail. Performance equivalent to stepping up sensor sensitivity without noise penalty.
• 1/1.8" sensor format — ensures compatibility with the corresponding Axis camera body (02367-001 pairs with 1/1.8" sensor platforms). Minimizes optical vignetting and corner softness across the field of view.
• i-CS mount with automated control — camera firmware directly manages focus position, zoom, and iris. Eliminates manual tweaking post-installation and enables rapid refocus during object tracking or scene transitions. Faster response than servo-driven manual systems.
• IR-corrected optics — maintains accurate white balance when paired with Axis cameras equipped with removable IR-cut filters for night-vision operation. Prevents color shift during day/night transitions.
• Compact form factor: 59 x 67.5 mm (2.3 x 2.7 inches) — fits within tight ceiling or wall-mounted housings without requiring oversized enclosures or additional space planning.

Integration and Compatibility

The Axis 02367-001 integrates with Axis camera platforms supporting the i-CS lens mount standard. Consult the specific Axis camera documentation to confirm i-CS compatibility. The lens requires no external focus motor, servo controller, or manual adjustment mechanism — the camera body handles all optical control through the i-CS protocol. This approach reduces wiring complexity and eliminates a common failure point in traditional varifocal deployments.

Installation involves mechanical mounting of the lens to the camera body and a single-step firmware configuration to enable autofocus. No additional power draw, no separate control cables.

When to Choose a Different Model

If your deployment requires a fixed focal length (e.g., dedicated entrance monitoring at a known distance), a fixed-focus lens reduces optical complexity and cost. If wider coverage at closer distances is essential, consider lower focal-length ranges (2.8–8 mm). For extreme low-light scenarios (0.001 lux), larger apertures (F1.2 or faster) or supplemental illumination may be necessary. Consult the Axis camera's sensor performance specifications to confirm the aperture-to-ISO trade-off supports your scene lighting.

Typical Deployment Scenarios

• Airport and transportation hub perimeter monitoring with adaptive zoom during object tracking
• Industrial warehouse and open-floor security where fixed mounting points limit pan-tilt capability
• Urban parking structures, loading docks, and mixed-lighting environments
• Facility entrances and hallways where focal-length flexibility reduces camera count

Frequently Asked Questions

Q: Is the 02367-001 compatible with all Axis camera models?

A: No. The 02367-001 is designed for Axis camera bodies with the i-CS lens mount and 1/1.8" sensor format. Verify your camera model's lens mount specification and sensor size in the camera's technical documentation before ordering. Mounting a lens to an incompatible camera will not function and may cause physical damage.

Q: What is the field of view range?

A: The 3.9–10 mm focal length range on a 1/1.8" sensor delivers a field of view from approximately 57° (wide) at 3.9 mm to 22° (telephoto) at 10 mm. Exact angles depend on the specific camera body's sensor cropping and optical characteristics. Confirm with your camera's field-of-view calculator.

Q: Does the 02367-001 support manual focus override?

A: The i-CS mount automates focus control via the camera firmware. Manual override capability depends on the camera platform's software. Check your camera's user guide for manual focus settings within the web interface or management software.

Q: Can I use the 02367-001 with removable IR-cut filters for night vision?

A: Yes. The lens includes IR correction to maintain accurate color rendering when IR-cut filters are removed. Pair it with an Axis camera that supports hot-swappable or motorized IR-cut filter removal for automated day/night mode transitions.

Q: What are the power requirements for the 02367-001?

A: Power is supplied entirely through the camera body via the i-CS mount. No separate power connector or external controller is required. The lens introduces minimal additional current draw to the camera's PoE budget (typically under 2W additional).

Q: Does the 02367-001 include mounting hardware?

A: The lens mounts directly to i-CS-compatible Axis camera bodies. No additional mounting hardware is shipped. The camera body provides the mechanical interface.

Perspective based on aggregated IP Security Depot and affiliated engineering team experience.

The Axis 02367-001 varifocal lens represents a solid choice for integrators deploying intelligent surveillance networks where automated optical control and proven optics matter. The i-CS mount eliminates focus hunting and lens drift artifacts common with manual varifocal systems, resulting in faster object tracking and cleaner video output during pan operations or rapid scene transitions. The 3.9–10 mm range (2.6x magnification) balances wide situational awareness with targeted detail capture — particularly valuable in open surveillance zones where dedicated pan-tilt-zoom functionality may be limited by cost or network topology.

Technical Highlights:

• F1.5 maximum aperture: Outperforms typical F2.0 designs by roughly 77% in light transmission — measurable gain in dim parking areas and night-vision scenarios where shutter/ISO trade-offs otherwise degrade temporal resolution and noise performance.
• i-CS automated control: Camera firmware handles all focus, zoom, and iris adjustments in real time. Eliminates manual recalibration drift and reduces single points of failure compared to servo-driven varifocal systems.
• IR-corrected optics: Maintains color accuracy across day/night filter transitions; critical for facilities using motorized or removable IR-cut filters for automated night-vision switching.
• 1/1.8" sensor pairing: Designed for Axis platforms with matching sensor formats; minimizes vignetting and ensures optimal optical performance across the field of view.

Deployment Considerations:

• Compatibility verification is non-negotiable: The 02367-001 requires a compatible i-CS mount body and 1/1.8" sensor. Confirm your camera model in Axis documentation before purchase — mounting incompatible optics introduces mechanical and optical failures.
• Field of view planning: The 3.9–10 mm range provides 57° (wide) to 22° (tele) coverage on 1/1.8" sensors. Pre-calculate coverage maps for your site geometry to avoid dead zones or excessive overlap.
• Low-light aperture limits: F1.5 is excellent for mixed lighting, but 0.001 lux scenarios (dark warehouses, unlit perimeter zones) may still require supplemental IR illumination or wider apertures in specialized low-light lens variants.

For security operations deploying fixed or semi-fixed camera positions and prioritizing automated, maintenance-free optical behavior with consistent image quality across day/night transitions, the 02367-001 delivers measurable performance gains over fixed-focal-length or manual varifocal alternatives. Integration with Axis ACAP-capable platforms further extends this lens with edge analytics and custom application development.
