Product Overview
For installers deploying covert surveillance across multiple points in a single facility, the AXIS F2115-R Varifocal Sensor Unit offers a practical and scalable solution in an 8-pack format. This modular remote sensor head is designed to be hidden in locations where a conventional camera would be impractical or immediately visible, including recessed into counters, mounted inside vehicles, tucked within ceiling voids, or positioned in tight architectural spaces. Featuring a varifocal lens spanning 3.2 to 5.7 mm, the sensor can be adjusted to deliver a horizontal field of view between 56.3 and 107.4 degrees at 1080p, giving installers real framing control even in confined deployment environments. The ruggedised SMA-FAKRA connector withstands vibration and supports cable runs up to 30 m from the main unit. With an operating temperature range of -40 to 60 degrees Celsius, this sensor unit suits both indoor and challenging environmental conditions. It is compatible with the AXIS F9104-B, F9111, F9114, and F9114-B main units.
Key Capabilities
Varifocal Lens for Covert Framing
The 3.2-5.7 mm varifocal lens (F2.2-F3.1) allows installers to fine-tune the field of view after the sensor is hidden in position, eliminating the need to physically reposition the unit to correct framing in tight or concealed spaces.
1080p at 60 fps
Full HD 1080p capture at up to 60 frames per second delivers smooth, detailed footage of fast movement. At 720p the sensor can reach 180 fps, which is useful in environments where rapid motion capture is a priority.
Ruggedised SMA-FAKRA Connector
The SMA-FAKRA connector is built to handle vibration in mobile and industrial environments. It supports cable runs of up to 30 m using compatible Axis cables, giving installers flexibility in where the main unit is located relative to each sensor head.
Extended Temperature Range
Rated to operate from -40 to 60 degrees Celsius, with intermittent tolerance up to 70 degrees, this sensor suits deployments beyond climate-controlled interiors, including vehicle cabins, kiosks, outdoor enclosures, and industrial environments.
8-Pack Format for Multi-Point Deployment
Supplied as a pack of 8 sensor units, the 02639-021 is suited to projects requiring coverage across multiple discreet points from a centralised main unit infrastructure, reducing per-unit cost and simplifying procurement for larger installations.
Best For
- Covert Counter and Reception Monitoring: The compact sensor head can be recessed into countertops or reception furniture where a visible camera is not suitable, with the varifocal lens allowing framing adjustment after concealment.
- Vehicle and Mobile Installations: The ruggedised SMA-FAKRA connector and wide operating temperature range make this sensor suitable for in-vehicle surveillance deployments including buses, trains, and fleet vehicles.
- Multi-Sensor Discreet Coverage: Projects requiring several independent sensor viewpoints fed into a small number of main units benefit from the 8-pack format, which suits gaming venues, retail environments, and banking interiors.
- Challenging Thermal Environments: The -40 to 60 degree Celsius operating range covers cold storage facilities, industrial production areas, and outdoor kiosks where standard indoor sensors would fail.
Why Choose the AXIS F2115-R Varifocal Sensor Unit
The AXIS F2115-R is not a standalone camera. It is an engineered component of the Axis modular F-series system, and that distinction matters. Where a standard miniature camera provides a fixed field of view after installation, the F2115-R’s varifocal 3.2-5.7 mm lens gives installers the ability to adjust framing once the sensor is in its final concealed position. The 1/2.8″ CMOS sensor delivers 1080p at 60 fps, maintaining image quality even where sensor placement is dictated by concealment rather than optimal positioning. The aluminum housing is PVC and BFR/CFR free, and the 5-year warranty reflects Axis’s confidence in the build quality. For projects requiring 8 discreet sensor points, procuring the 8-pack eliminates repeat ordering and simplifies project logistics. Available at Security Wholesalers, the AXIS F2115-R Varifocal Sensor Unit is a purpose-built component for installers who need reliable, adjustable covert coverage at scale.
Buyer Decision Tips
Compatibility Check Before Purchase: The AXIS F2115-R Varifocal Sensor Unit uses SMA-FAKRA connectors and is designed exclusively for 2nd generation Axis F-series main units, specifically the F9104-B, F9111, F9114, and F9114-B. It is not compatible with 1st generation main units including the F34, F41, or F44. Confirm which main unit generation is already installed or being procured before ordering this sensor, as mixing generations will result in non-functional installations.
Cable Run Planning: Each sensor unit supports a maximum cable run of 30 m from the main unit using compatible Axis SMA-FAKRA cables. Plan cable routing before specifying sensor placements, particularly in large venues where sensor points may be spread across a wide floor plan. The 30 m limit should be measured along the actual cable path, not straight-line distance.

Ideal Use Cases
Gaming and Casino Floors
The compact sensor head can be positioned inside gaming machines or embedded in furniture to monitor table activity without alerting subjects. The varifocal lens allows framing to be set precisely for each machine or table position after concealment.
Retail Loss Prevention
Concealed within display fixtures, POS counters, or shelving, the F2115-R provides covert coverage of transaction areas and high-value product zones where a visible camera would affect customer behaviour or store aesthetics.
Public Transport and Fleet Vehicles
The ruggedised SMA-FAKRA connector handles ongoing vibration in mobile environments, and the -40 to 60 degree Celsius operating range covers the temperature extremes found inside buses, trains, and commercial vehicles across Australian climates.
Banking and ATM Monitoring
The small form factor and varifocal adjustment make the F2115-R suited to installation within ATM enclosures or bank teller counters, where the sensor must be concealed and framed to capture face-level detail at a fixed transaction point.
Industrial and Kiosk Environments
With IP50 dust ingress protection and a wide operating temperature tolerance, the sensor is suitable for kiosks, industrial control rooms, and manufacturing environments where dust exposure and temperature fluctuations rule out standard indoor cameras.
Choosing the Right Model
- Choose this model if: You are deploying 8 or more covert sensor points using 2nd generation Axis F-series main units (F9104-B, F9111, F9114, or F9114-B), and need varifocal flexibility to adjust framing after the sensors are concealed in their final positions.
- Choose a different model if: Your installation uses 1st generation Axis F-series main units (F34, F41, or F44), as this sensor is not compatible with those units. If you require built-in IR illumination for low-light or zero-light environments, a different sensor model with active IR should be evaluated instead.
- Choose a different model if: You need fewer than 8 sensor units for a single project. The single-unit variant (02639-001) provides the same sensor in a quantity that avoids excess stock where only a small number of covert points are required.
FAQs
- What main units is the AXIS F2115-R Varifocal Sensor Unit compatible with?
The F2115-R is compatible exclusively with 2nd generation Axis F-series main units: the AXIS F9104-B, F9111, F9114, and F9114-B. It uses SMA-FAKRA connectors and will not connect to or function with 1st generation main units including the F34, F41, or F44. Confirm your main unit model before ordering.
- How is the sensor powered?
Power is delivered to the sensor unit through the SMA-FAKRA cable from the main unit. There is no separate power input or PoE connection on the sensor itself. Typical power draw is 1 W, with a maximum of 1.7 W. No additional power supply is required at the sensor end of the installation.
- What is the maximum cable distance between the sensor and the main unit?
Compatible Axis SMA-FAKRA cables support a maximum run of 30 m (98 ft) between the sensor unit and the main unit. This distance must be measured along the actual cable route, including any conduit bends or ceiling void paths, not as a straight-line measurement.
- Does the AXIS F2115-R have built-in IR for low-light recording?
No. The F2115-R does not include built-in infrared illumination. It has a fixed IR-cut filter and a minimum illumination of 0.1 lux in colour mode. For environments where there is no ambient light source during the monitoring period, a sensor unit with active IR illumination should be considered instead.
- Can the varifocal lens be adjusted after the sensor is installed in a concealed position?
Yes. This is one of the primary practical advantages of the F2115-R over fixed-lens sensor units. The 3.2-5.7 mm varifocal lens can be adjusted to change the field of view between 107.4 and 56.3 degrees horizontally at 1080p, allowing installers to refine framing once the sensor is in its final hidden position rather than repositioning the unit itself.
- Is the AXIS F2115-R Varifocal Sensor Unit suitable for outdoor installation?
The sensor is rated IP50, which provides protection against dust ingress but no rated protection against water or moisture. It is not designed for direct outdoor exposure to rain or washdown. It can be used in outdoor enclosures or kiosk installations where it is shielded from direct moisture, and its operating temperature range of -40 to 60 degrees Celsius supports a wide range of ambient conditions.
- Does this 8-pack include cables or main units?
No. The 02639-021 pack contains 8 AXIS F2115-R Varifocal Sensor Units only. Compatible SMA-FAKRA cables and 2nd generation main units are sold separately. Installers should plan and procure cables and main units for each sensor point as part of a complete system design. For guidance on compatible accessories, the team at Security Wholesalers can assist with system configuration advice.
