The Axis Communications Q1921-E Thermal Network Camera (Outdoor), with thermal imaging technology, converts thermal radiation to images. Without needing any visible light, it allows you to detect objects, people, and incidents even in complete darkness including difficult conditions such as smoke, haze, dust, and light fog. The camera comes with a built-in heater for the germanium window that allows thermal radiation to pass.
With an uncooled micro bolometer image sensor, 19mm lens, and a resolution of 384 x 288, the thermal camera displays bright and intense color images, created digitally to help distinguish details in the scene. The images show temperature variations in the scene. The camera supports multiple H.264 streams and motion JPEG at 30 frames-per-second and also allows you to scale up the images up to 768 x 576 as well as to standard VGA resolutions.
The thermal network camera has a built-in support for pan/tilt heads using the Pelco-D protocol. It includes image setting features such as privacy masking, exposure control, mirroring of images, text and image overlay, and brightness. With two-way half-duplex support, the camera enables you to communicate with the intruders from the operator's base station. The camera supports an open API (Application Programming Interface) for software integration, including the ONVIF specification and the VAPIX and AXIS Camera Application Platform from Axis Communications.
Password usage restricts access to unauthorized persons and IP filtering restricts access to 1 or more user groups. User groups can be created with an IP address range being defined for each group. Intelligent video capabilities include video motion detection, audio detection, and active tampering alarm. The built-in HD/SD memory card slot can store up to 1 month of recordings. Power is supplied to the camera through PoE (Power over Ethernet); hence the camera gets power from the network itself without any extra wiring for auxiliary power outlets.
The thermal camera can be ideally used for applications that require 24 hours surveillance such as retail stores, office buildings, prisons, and warehouses.
