AXIS Q87-E Series comprises two models: AXIS Q8721-E provides a visual HDTV 1080i network camera with 10x optical zoom and autofocus combined with a thermal network camera with 384x288 resolution. AXIS Q8722-E provides the same HDTV-quality camera and a thermal camera with higher VGA (640x480) resolution. Both models are connected to the network using one Ethernet cable and offer four different lens options. Since thermal technology detects heat signatures in a scene, the thermal network camera can achieve higher detection accuracy in complete darkness and adverse weather conditions. The visual camera with high-definition video allows for better identification of an object, animal or person. At night, the HDTV camera benefits from optional add-on IR illuminators with a range of more than 100 yards.
