VIVOTEK, the Taiwanese IP surveillance product manufacturer, introduces a new multiple-sensor network camera, MS8391-EV, pictured. This camera features four 3-Megapixel CMOS sensors with 180-degree panoramic views, and built-in IR illuminators effective up to 30m. It’s designed for city surveillance in places requiring wide coverage, such as a campus, airport, and car parking.
　　With its design of four 3MP CMOS sensors, the camera provides a detailed 180-degree panoramic view with it’s claimed minimal blind spots. This both maximizes the field of view and reduces the total number of cameras required, thereby saving on both installation time and maintenance costs. The camera comes with IK10 and IP66-rated housing and offers a minus 50 degrees C to 60 degrees C temperature range, for outdoor operation.
　　The camera also has Smart IR technology, to prevent over-exposure and noise reduction to instantaneously adjust the IR lighting intensity in response to changes of light in the ambient environment. With its 3D Noise Reduction and Smart Stream, the product can deliver quality images under low light, while optimizing bandwidth usage. Users can choose a corner mount or pole mount accessories, for best mounting and operation.

　　室外全景解决方案
　　台湾的IP监控产品制造商VIVOTEK公司，推出了一个款新的MS8391-EV型多传感器网络摄像机。这款摄像机具有4个300万像素的CMOS传感器和180度视野，内置的红外照明有效距离为30米。它被设计用于大范围覆盖的城市监控，例如校园、机场和停车场。
　　凭借4个300万像素的CMOS传感器，摄像机提供了最小盲区细致的180度全景视野。 这2个最大化的视野及减少了所需摄像机的总数，从而节省了安装时间和维护成本。该摄像机配备了IK10 和 IP66防护等级的外壳和零下50度至60度的户外正常工作范围。该相机还具有智能的IR技术，以防止过度曝光和降噪，针对周围环境光的变化瞬间调整红外照明强度。凭借其3D降噪和智能流，该产品可以低光照下提供高质量的图像，同时优化带宽的使用。
