AXIS F41 Main Unit is designed for use with an AXIS F sensor unit in extremely discreet video surveillance applications. The main unit can be installed in a sheltered area, while the sensor units can be placed in tight places indoors or outdoors up to 8, 12 or 15 m (26, 39 or 49 ft.) away, depending on the sensor unit and if a cable accessory is supported. The rugged and feature-rich AXIS F41 Main Unit is suitable for a variety of demanding applications, such as in casinos, stores, ATMs (automated teller machines) and vehicles.
Wide Dynamic Range (WDR) – Forensic Capture
AXIS F41 offers WDR – Forensic Capture, which can be activated when the main unit is connected to an AXIS F Sensor Unit that supports this feature. Axis’ WDR – Forensic Capture enables a high level of detail to be visible in both bright and dark areas of a scene—an important consideration in surveillance applications.
The technology is ideally suited for scenarios such as at entrances or in front of ATMs where the subject may be dark against a bright background, or in nighttime situations where the camera must handle low-light environments together with bright lights from vehicles, street lamps, signage and stores.
AXIS F41, together with an AXIS F Sensor Unit, provides color video in light as low as 0.3 lux.

AXIS F41 supports HDTV 1080p at 50 or 60 frames per second for 1080p sensor units. This is ideal for capturing fast-moving objects and generating smoother video. It delivers HDTV 1080p at 25 or 30 frames per second when WDR – Forensic Capture is used. For a 720p sensor unit, AXIS F41 delivers full frame rate HDTV 720p video.
AXIS F41 supports Axis’ Zipstream technology, which is a more efficient implementation of the H.264 video encoder. It can lower bandwidth and storage use by an average of 50% or more for many surveillance scenarios. It ensures that important details are maintained while unnecessary data is removed.
Rugged, easy-to-install design
AXIS F41 can withstand tough conditions such as vibrations, shocks and temperature fluctuations, which make it ideal for use in emergency vehicles such as police cars, fire trucks, ambulances and armored trucks such as those used to transport money and other valuable goods.
The main unit has also been designed for easy installation in cabinets and small enclosures as all the connectors are placed on one side of the unit so that cables go in one direction and don’t take up unnecessary space.
The bottom of the unit can also hook directly onto a DIN rail.
With a built-in SD card slot, AXIS F41 gives users the option of storing video locally on a full-sized SD card.
It also offers two-way audio and four configurable input/output ports for external devices to enable enhanced alarm management. An RS232 port allows for integration of external data to the video. The main unit can be powered using Power over Ethernet or DC power.
Intelligent video capabilities include video motion detection, active tampering alarm and downloadable applications through the AXIS Camera Application Platform.
