AXIS Q1931-E Thermal Network Camera is a perfect complement to any network video system that needs to secure an area 24 hours a day, seven days a week. The camera uses thermal imaging, which allows users to detect people, objects and incidents in complete darkness and difficult conditions such as smoke, haze, dust and light fog. Thanks to a new noise filter that improves thermal imaging contrast, blur and ghost effects are removed and images are kept sharp in all conditions. Even as noise levels are kept low, no temperature information or details are lost. It makes a scene and the objects and events in it easier to recognize.
For demanding outdoor video surveillance
AXIS Q1931–E is a bullet-style outdoor-ready model that is designed to withstand harsh weather conditions. It comes with a built-in heater for the window. It's ideal for cost efficient 24/7 area or perimeter surveillance of all security applications such as roads, tunnels and airports. The camera is further protected with shock detection, a capability that sends an alarm to personnel during attempted vandalism.
Key IP-Surveillance features
AXIS Q1931-E Thermal Network Camera supports H.264 video compression, which reduces bandwidth usage and storage needs by up to 80% compared to Motion JPEG. The camera provides multiple, individually configurable video streams in H.264 and Motion JPEG. AXIS Q1931-E has two-way audio support, which allows the user to communicate with visitors and intruders.
Wide detection range and intelligent video applications
With a resolution of 384x288 pixels and four lens alternatives, AXIS Q1931-E can optimize detection performance to meet most application requirements. 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. Intelligent video applications such as cross-line detection and video motion detection are included.
