Network cameras, introduced by Samsung Techwin America at ASIS 2011, capture high-resolution images, day and night, and incorporate 15 built-in infrared (IR) LED illuminators with a range of 50 or more feet. The ONVIF-compliant high-performance dome cameras also include motorized 3-8.55mm (2.8x) vari-focal lenses that allow zoom and focus settings to be adjusted remotely after installation. Dome housings are vandal-resistant to protect against tampering or physical attack and IP66 environmentally rated for severe or varying weather conditions. The cameras can be powered via PoE and 24vAC.
