Adopting a 18x optical zoom lens and sophisticated pan/tilt mechanism, the SD8161 is able to capture fine detail at top-notch quality, and is especially suitable for wide open indoor spaces such as airports and lobbies where highest levels of reliability and precision are always required.
The SD8161 supports high-performance H.264/MJPEG compression technology and offers extra smooth video quality with resolution of up to 30 fps @ 1080p.
With WDR Enhancement technology, the SD8161 can also cope with challenging lighting conditions and generate image quality close to the capabilities of the human eye.
With a sophisticated pan/tilt mechanism, the camera provides fast, precise movement with continuous 360-degree pan and 220-degree tilt. Users can also easily control the lens position via a mouse or a joystick to track the object of interest and set up to 256 preset positions.
With its built-in auto tracking feature, the SD8161 further provides instantaneous reaction to suspicious moving objects in wide area locations, even before operators are aware of activity. With other advanced features such as MicroSD/SDHC/SDXC card slot, 802.3at compliant PoE Plus and 30 fps high quality video, the SD8161 is the best choice for the most demanding indoor surveillance applications
