AXIS Q1931-E PT Mount Thermal Camera

Wide thermal coverage with pan/tilt flexibility

Recommended replacement: AXIS Q1941-E PT Mount 

Easy verification

A broad range of lenses make it easy to detect and identify people, objects and incidents. Thanks to a new filter that removes the blur and ghost effects, the images are kept sharp in all conditions. AXIS Q1931-E PT Mount cameras offer an improved thermal imaging contrast, keeping the noise levels low at the same time as no details or temperature information are lost. The scene is easier to understand; surroundings are recognizable, and objects, accidents or people are identifiable.

Thermal cameras

AXIS Q1931-E PT Mount includes intelligent video applications, such as AXIS Cross Line Detection license and AXIS Video Motion Detection 2.1. The thermal camera can complement any IP surveillance system being the first to detect accidents and sending notification to another network camera.

Based on the alarm trigger, a PTZ network camera can be re-directed to the point of interest. Since thermal cameras are less sensitive to problems with light conditions and shadows, they can achieve higher accuracy and less false alarms than conventional cameras in most applications.

Versatile, outdoor video surveillance

AXIS Q1931–E PT Mount is a bullet-style outdoor-ready model that is specifically designed to be mounted on pan-tilt motors. This allows the camera to cover larger areas and also gives the option of directing the camera upwards. The thermal camera includes a serial port for RS422/RS485 communication with pan-tilt motors. (Pan-tilt motor not included). It comes with a built-in heater for the window. The camera is further protected with shock detection, a capability that sends an alarm to personnel during attempted vandalism.

Easy and flexible installation 

AXIS Q1931-E PT Mount is easy to install and can easily be integrated with existing security systems. The following installation video shows how to mount the camera on an pan/tilt head.
