VIVOTEK FD8171 is a professional indoor dome network camera offering 30 fps @ 3-Megapixel or 60 fps @ 1080p resolution with superb image quality. As a professional day/night camera, FD8171 adopts a Smart IR technology which prevents overexposure and provides noise reduction to adjust the IR lighting intensity instantaneously based on the changes of lights in the ambient environment.
Featuring 3D Noise Reduction Technology, it enables the FD8171 to capture clear, polished video under low-light conditions, which also helps to reduce bandwidth from sensor noise. Combined WDR Enhanced technology, users can identify image details in extremely bright as well as dark environments.
In addition, FD8171 implements Smart Stream Technology, which allows users to set region of interests (ROIs) for improved clarity without raising the bitrate so as to optimize storage and bandwidth efficiency.
To provide top-notch image quality, FD8171 also comes with a P-iris lens, which controls the iris with extreme precision with its built-in stepper motor. By using software controls, the lens maintains the iris opening at an optimal level at all times, resulting in superior sharpness and depth of field as well as image quality. Furthermore, for installers, properly adjusting the focus of a megapixel network camera can be difficult due to the image detail. Thus, FD8171 is also designed with VIVOTEK' s Smart Focus System to make installation and adjustment easier by allowing remote focus and zoom adjustment.
