Product Overview
For professional installers working with AXIS P3925-R or AXIS P3935-LR dome cameras, the AXIS LENS M12 8.0MM F1.8 IR provides a purpose-built lens replacement option engineered for day/night optical performance. With an 8mm focal length and a horizontal field of view of 41 degrees, this lens is suited to applications where a narrower, more directional angle of coverage is needed, such as corridor monitoring, long-approach entrance coverage, or focused target zones. The F1.8 aperture supports stronger light gathering in lower ambient conditions, and the IR-compatible design works with cameras fitted with a removable IR-cut filter. Each unit ships with a lens tool included, and the pack of 10 makes this a practical bulk procurement option for multi-camera deployments or organisations maintaining a larger fleet of compatible AXIS dome cameras. A 3-year warranty is included.
Key Capabilities
8mm Focal Length with 41-Degree Horizontal FoV
The 8mm focal length delivers a narrower, more focused view compared to standard wide-angle dome lenses. With a horizontal field of view of 41 degrees and a vertical field of view of 22 degrees, this lens is suited to corridor runs, long driveways, or defined target zones where tight framing is required.
F1.8 Aperture for Low-Light Conditions
An F1.8 aperture allows more light to reach the sensor than slower lenses, which supports improved image quality in dimly lit environments. This is particularly relevant in dome camera installations covering low-light indoor areas or poorly lit outdoor approaches at night.
IR-Compatible Optical Design
This lens is designed without an IR-cut filter and is intended to work with day/night cameras that have a removable IR-cut filter built in. This ensures consistent focus performance across both visible light and infrared wavelengths, avoiding the focal shift that can degrade night-time image sharpness with non-IR-corrected lenses.
Pack of 10 with Lens Tool Included
Supplied in a pack of 10 units complete with a dedicated lens tool, this product is suited to installers managing multi-camera sites or maintaining a larger fleet of compatible AXIS dome cameras. Bulk packaging reduces per-unit cost and simplifies procurement for larger projects.
Best For
- Corridor and Long-Approach Monitoring: The 8mm focal length and 41-degree horizontal field of view suit installations where a tighter, more directional angle is needed to cover hallways, single-lane entries, or defined zones rather than broad open areas.
- Fleet Maintenance and Lens Replacement: Organisations running multiple AXIS P3925-R or P3935-LR dome cameras can use this pack of 10 to standardise lens specifications across their installation fleet or replace lenses during routine servicing.
- Bulk Multi-Site Procurement: Security integrators managing deployments across several sites benefit from the 10-unit packaging, which provides consistent lens specifications across locations without sourcing individual units separately.
Why Choose the AXIS LENS M12 8.0MM F1.8 IR
Where the standard factory-fitted lens on a dome camera provides a wide field of view suited to open-area coverage, the AXIS LENS M12 8.0MM F1.8 IR is a purpose-built alternative for installations that require a narrower, longer-reach angle. The 8mm focal length narrows coverage to 41 degrees horizontally, making it the right fit for corridors, single-lane access points, or focused monitoring zones where a wide-angle lens would dilute detail across too broad a scene. The F1.8 aperture supports better low-light performance without relying solely on IR illumination, and the IR-compatible design ensures focus remains accurate in both day and night modes. Compatibility is confirmed for the AXIS P3925-R and AXIS P3935-LR. The 10-unit pack with included lens tool is a practical choice for professional installers, and the product is available at Security Wholesalers with a 3-year warranty backed by Axis.
Buyer Decision Tips
Confirm Camera Compatibility Before Ordering: This lens is confirmed compatible with the AXIS P3925-R and AXIS P3935-LR. It requires a camera with an M12 lens mount and a removable IR-cut filter. If your cameras use a CS or C-mount, or have a fixed integrated lens, this product will not be applicable. Always verify the mount type and lens replacement support in your specific camera model’s documentation before ordering a pack of 10.

Ideal Use Cases
Corridor and Hallway Monitoring
The 41-degree horizontal field of view makes this lens well suited to long, narrow indoor corridors where a wider lens would waste resolution on walls rather than the walking zone. Compatible dome cameras mounted with this lens can provide tighter subject detail across the corridor length.
Single-Lane Entry and Exit Points
Entrances, boom gate approaches, or single-lane vehicle access points benefit from a narrower lens angle that keeps the frame tightly on the lane. The 8mm focal length allows the camera to capture usable detail at longer distances compared to a standard wide-angle lens in the same position.
Fleet Servicing and Lens Standardisation
Facilities operating multiple AXIS P3925-R or AXIS P3935-LR cameras can use this 10-unit pack to standardise lens specifications across all units. Having spare lenses on hand also supports faster servicing without waiting on individual unit lead times.
Low-Light Indoor Zones
The F1.8 aperture gathers more available light than slower lenses, making this a useful choice for areas with inconsistent or limited artificial lighting. Combined with a day/night camera’s removable IR-cut filter functionality, this lens supports improved visibility in transitional lighting conditions.
Choosing the Right Model
- Choose this model if: You are installing or maintaining AXIS P3925-R or AXIS P3935-LR dome cameras and need an 8mm narrow-angle lens for corridor, long-approach, or focused zone coverage, particularly where a standard wide-angle lens provides too broad a field of view for the required detail level.
- Choose a different model if: Your cameras use a different lens mount type or do not have a removable IR-cut filter, as this lens requires both. If you need a wider field of view to cover open rooms or broad areas, a shorter focal length lens would be more appropriate. This lens is also not compatible with cameras outside the confirmed AXIS P3925-R and AXIS P3935-LR models.
FAQs
- Which cameras is this lens confirmed compatible with?
This lens is confirmed compatible with the AXIS P3925-R and the AXIS P3935-LR. Both cameras use an M12 lens mount and are equipped with a removable IR-cut filter, which is required for this lens to function correctly in day/night switching operation. Compatibility with other AXIS models has not been confirmed in the product data.
- Why would I use an 8mm lens instead of the standard factory-fitted lens?
The 8mm focal length provides a narrower horizontal field of view of 41 degrees compared to shorter focal lengths that offer wider coverage. This suits locations where you need to monitor a defined zone at a greater distance, such as a hallway, a vehicle entry lane, or a long outdoor approach, rather than capturing a broad open scene.
- What does the F1.8 aperture mean in practical terms?
A lower F-number aperture allows more light to pass through the lens to the camera sensor. F1.8 is a relatively fast aperture that supports better image quality in lower-light conditions compared to lenses with F2.0 or higher ratings. For dome cameras covering areas with limited ambient lighting, this can make a noticeable difference in image quality before the camera switches to IR mode.
- Why does this lens specify IR compatibility and what does that mean?
IR-compatible lenses are designed to maintain consistent focus across both visible light and infrared wavelengths. Standard lenses can experience a focus shift when a day/night camera removes its IR-cut filter at night and infrared light becomes the primary illumination source. Using an IR-compatible lens prevents this focal shift and ensures the image stays sharp throughout the day/night cycle.
- What is included in the pack and how many units are supplied?
Each pack contains 10 lens units along with a lens tool. The lens tool is used for fitting and adjusting the M12 lenses during installation. The 10-unit pack is designed for professional installers or organisations managing multiple cameras, making it suitable for bulk procurement rather than single-unit replacement.
- What warranty applies to this lens and where can I purchase it?
This lens carries a 3-year warranty from Axis. It is part of the Security Wholesalers range, supplied as a genuine Axis accessory under SKU 02009-001. If you are procuring lenses for a large installation or require documentation for a commercial warranty claim, it is advisable to retain your purchase receipt and packaging details.
