Thermal imaging
AXIS FA4090-E offers all the benefits of thermal imaging at a price that’s within reach. Used together with AXIS FA54 Main Unit and analytics such as AXIS Guard Suite, it reliably detects people, vehicles and objects regardless of light conditions or attempts at camouflage.
AXIS FA4090-E creates images based on the heat that radiates from an object, vehicle or person. And because thermal cameras are less sensitive to lighting conditions, such as shadows, backlight, darkness and camouflaged objects, you are guaranteed reliable images.
Mix thermal and visual imaging all in one
AXIS FA 4090-E Thermal Sensor Unit can be used in a single, or multi-channel setup to create a flexible, tailored approach to surveillance depending on your needs – indoors or out. Using AXIS FA-Series, you can use up to four sensor units, together with AXIS FA54 Main Unit. It also allows you to mix, for instance, thermal cameras with visual cameras in one stream. The sensor unit can be used for intruder detection and allows you to place a visual sensor unit in the same area to further identify whether or not there is a threat.
Furthermore, you can build a flexible perimeter protection solution using analytics, such as AXIS Guard suite together with a modular solution with four thermal cameras. This could be useful for outdoor environments, such as at construction sites to protect containers with valuable materials. Modular thermal cameras helps keep the area safe in a cost-efficient way while reducing the number of false alarms.
Flexible and discreet
This compact, discreet unit can be mounted behind surfaces, in recesses, on walls or inside a bullet-shaped accessory. Together with AXIS FA54 Main Unit the set up supports Zipstream, analytics, HDMI support for connection to a surveillance or public viewing monitor (PVM) and audio input/output ports. Plus, four configurable input/output ports allow you to connect to external devices such as door locks and lights for handling alarm events and local storage.
