Axis temperature alarm cameras can be used where there is a need for temperature monitoring, such as power generating facilities, fire hazard areas or industrial processes involving self-igniting materials. They can be installed on a wall or ceiling. The outdoor-ready and bullet-style AXIS Q2901-E Temperature Alarm Camera delivers thermal imaging in 336x256 resolution. The camera supports up to six temperature alarm zones that can be used to trigger an alarm. It is based on temperature changes: either above or below a pre-set threshold, or temperature increase rate. The camera also offers spot temperature functionality for instant scene spot measurement, and isothermal palettes make it easier to visualize hot spots to identify, i.e. overheated equipment. Isothermal palettes highlights, unlike traditional color palettes, temperature-spans in the image. A built-in window heater is designed to withstand harsh weather conditions.
