Product Overview
Designed for installations where concealment and placement flexibility are non-negotiable, the Axis F2115-R is a 2MP varifocal modular sensor unit built for the Axis F Series ecosystem. Its compact 50mm body and ø29.8mm diameter allow it to be positioned in spaces where a conventional camera housing would be impractical or intrusive: vehicle cabins, public transport carriages, narrow corridors, ceiling voids, or discreetly integrated into retail or reception fixtures. The varifocal 3.2-5.7mm lens provides a horizontal field of view adjustable from 107.4° down to 56.3°, giving installers the ability to frame the scene precisely without repositioning the unit. It captures full 1080p at up to 60 frames per second, or 720p at up to 180 frames per second for high-motion environments. The SMA-FAKRA connector improves resistance to vibration compared to standard connectors, making it particularly suited to vehicle-based deployments. The sensor operates across a temperature range of -40°C to 70°C intermittently, supporting demanding environmental conditions beyond typical indoor settings.
Key Capabilities
Varifocal 3.2-5.7mm Lens
The M12-mount varifocal lens adjusts from a wide 107.4° horizontal field of view down to 56.3°, allowing precise scene framing during installation without physically relocating the sensor unit. This is particularly useful in tight or fixed-mount positions where repositioning is not practical.
1080p at 60fps / 720p at 180fps
Full HD 1920×1080 capture at 60 frames per second delivers smooth, detailed footage in busy environments. For high-speed motion such as vehicle interiors or fast-moving pedestrian areas, 720p at 180fps captures motion with significantly reduced blur.
SMA-FAKRA Vibration-Resistant Connector
The SMA-FAKRA connector provides greater mechanical resistance to vibration than standard connectors. This makes the F2115-R a practical choice for bus, rail, or vehicle deployments where constant movement and vibration would otherwise risk intermittent signal loss with conventional sensor units.
Extended Temperature Range
Rated to operate from -40°C to 70°C intermittently, the sensor withstands temperature extremes found in vehicle engines bays, unheated transport compartments, or industrial areas subject to seasonal variation, well beyond what most compact modular sensors support.
Wide Dynamic Range and Low-Light Sensitivity
Built-in Wide Dynamic Range handles scenes with strong contrast between bright and shadowed areas, such as a vehicle doorway or an entry with backlit windows. A minimum illumination of 0.1 lux in colour mode captures usable detail in low ambient light without requiring supplementary lighting.
Best For
- Vehicle and Transport Surveillance: The SMA-FAKRA connector and wide temperature tolerance make this sensor well suited to bus, rail, and fleet vehicle installations where vibration and temperature swings are constant.
- Discreet Fixed Indoor Monitoring: The compact 50mm body allows flush or concealed mounting in retail fixtures, ceiling voids, reception counters, or corridor recesses where a standard camera housing would be visually intrusive.
- High-Frame-Rate Motion Capture: At 720p and 180fps, the F2115-R records fast-moving subjects with minimal motion blur, making it useful for transaction counters, turnstiles, or areas with rapid pedestrian throughput.
- Multi-Sensor F Series Installations: Installers running multiple sensor units from a single Axis F Series main unit benefit from the ability to place each sensor independently across a site while centralising recording and processing in one location.
Why Choose the Axis F2115-R
The F2115-R occupies a specific position within the Axis F Series as the varifocal option, distinguishing it from fixed-lens modular sensors by giving the installer genuine lens adjustment at the point of installation. Rather than committing to a fixed angle before the sensor goes into position, the 3.2-5.7mm range allows the field of view to be dialled in after mounting, which is valuable when the sensor is concealed inside a fixture or mounted in a location that is difficult to access again. The 60fps frame rate at full 1080p is higher than many comparable modular units, and the 180fps slow-motion option at 720p is a confirmed differentiator for motion-sensitive applications. The SMA-FAKRA connector addresses a real-world failure point in vehicle deployments that standard modular sensors do not resolve. Available through Security Wholesalers, the F2115-R is backed by a 5-year Axis warranty, which is longer than the standard 3-year cover common in this category.
Buyer Decision Tips
Main Unit and Cable Are Required Separately: The F2115-R is a sensor unit only. It does not operate as a standalone camera. You must have a compatible Axis F Series main unit and a 2nd generation Axis F Series cable such as the Axis TU6004-E or TU6005. The maximum supported cable run between the sensor and main unit is 30 metres. Confirm your main unit compatibility and cable length requirements before ordering the sensor.
No Infrared: Lighting Conditions Matter: The F2115-R has no built-in IR illumination. Its minimum illumination of 0.1 lux in colour mode means it requires ambient light to produce usable footage. For installations in areas that go fully dark at night, supplementary lighting or a different sensor with IR capability will be needed. For vehicle interiors, aircraft cabins, or consistently lit indoor spaces, the 0.1 lux sensitivity is generally sufficient.

Ideal Use Cases
Public Transport Vehicles
The SMA-FAKRA connector resists vibration during vehicle operation, and the -40°C to 70°C temperature range handles the thermal swings common in bus and rail environments. The compact sensor body sits discreetly within cabin trims or above doorways without protrusion.
Retail Fixture Integration
The ø29.8mm sensor can be integrated into shelving, countertops, or display fixtures at a point-of-sale or service counter. The varifocal lens allows field-of-view adjustment after the sensor is fitted into the fixture, without disassembly.
Corridor and Reception Monitoring
In corridors or reception areas where camera visibility is undesirable, the F2115-R can be recessed into ceiling panels or mounted behind apertures. The 107.4° wide-angle end of the varifocal range covers broad entry-point scenes from a single compact unit.
Transaction Counter Surveillance
At 720p and 180fps, the sensor captures hand movements, cash handling, or card exchanges with significantly reduced motion blur. Privacy masking allows specific screen or PIN pad areas to be excluded from recording while keeping the transaction zone in frame.
Multi-Sensor Building Installations
Where a single Axis F Series main unit serves multiple sensor positions across a floor or zone, the F2115-R can be placed up to 30 metres from the main unit. This reduces the number of network connections and recording devices needed across a multi-room or multi-entry layout.
Choosing the Right Model
- Choose this model if: You are building or expanding an Axis F Series installation, need a varifocal lens for post-installation field-of-view adjustment, require vibration-resistant connectivity for vehicle or transport deployment, or need a sensor that operates reliably across extreme temperature ranges.
- Choose a different model if: You need a standalone camera that records independently without an F Series main unit, require built-in IR illumination for use in fully dark environments, need an outdoor-rated sensor with a higher IP rating such as IP66 or IP67 for direct weather exposure, or are working outside the Axis F Series ecosystem entirely.
FAQs
- Does the Axis F2115-R work as a standalone camera?
No. The F2115-R is a sensor unit only and cannot record or stream independently. It must be connected to a compatible Axis F Series main unit using a 2nd generation Axis F Series cable such as the TU6004-E or TU6005. The main unit handles network connectivity, recording, and power delivery to the sensor.
- What cable is required, and is it included with the sensor?
No cable is included. You need a 2nd generation Axis F Series cable to connect the F2115-R to your main unit. The maximum supported cable length between the sensor and the main unit is 30 metres. Cables must be purchased separately and are available as dedicated Axis F Series accessories.
- Why does this sensor use an SMA-FAKRA connector instead of a standard connector?
The SMA-FAKRA connector provides greater resistance to vibration than standard connectors used on other F Series sensors. This matters significantly in vehicle, rail, or transport deployments where continuous movement and vibration can cause intermittent signal loss or connector wear over time with standard connections.
- What is the IP5X rating and does it mean this sensor can be used outdoors?
IP5X means the sensor is protected against dust ingress but has no confirmed rating for water resistance. It is designed primarily for indoor use, including within vehicle enclosures. For outdoor installations with direct exposure to rain or moisture, a sensor with an IP66 or IP67 rating and an appropriate protective housing would be required.
- Can the varifocal lens be adjusted after the sensor is mounted?
Yes. The 3.2-5.7mm varifocal lens can be adjusted after installation, which is one of the main advantages of this sensor over a fixed-lens alternative. This is particularly useful when the sensor is fitted into a fixture, recess, or vehicle trim where physically relocating the unit after initial mounting is not practical.
- Does the F2115-R have night vision or infrared capability?
No. The F2115-R has no built-in IR illumination. It relies on ambient light, with a minimum illumination of 0.1 lux in colour mode. For well-lit interiors, vehicle cabins with internal lighting, or areas with consistent ambient light, this is sufficient. Installations in spaces that go fully dark will require supplementary lighting.
- What warranty does the Axis F2115-R carry, and where is it available?
The F2115-R is backed by a 5-year Axis manufacturer warranty, which is longer than the 3-year cover typically provided on competitor modular sensors in this category. It is available through Security Wholesalers as part of the Axis F Series modular sensor range, alongside compatible main units and F Series cables.
