AXIS F Series offers a main unit and sensor units with pinhole, standard, varifocal, and fish-eye lenses for field of views up to 194 degrees in highly discreet surveillance installations. The main unit-- AXIS F41-- can connect to only one sensor unit at a time

AXIS F41 Main Unit supports the following features:
* Wide Dynamic Range (WDR) – Forensic Capture, which enables details from both bright and dark areas of a scene to be visible; ideal 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.
* HDTV 1080p video at up to 50/60 frames per second, ideal for capturing fast-moving objects and generating smoother video.
* Two-way audio
* Input/output ports to external devices for enhanced alarm management
* RS232 port for integration of external data to the video
* Full-sized SD card slot for local storage
* Power over Ethernet, as well as the option of connecting to an external power supply
* Intelligent video capabilities such as video motion detection, active tampering alarm and downloadable applications through the AXIS Camera Application Platform
