WizMind系列设备提供大华分析+功能,提供全面的、以人为本的分析解决方案。WizMind系列产品非常适合对具有复杂需求的应用,需要先进的分析功能。

系统概述
大华4 MP ePoE Night Color 2.0摄像机在边缘提供Analytics+功能,执行复杂的实时周界保护监视、智能运动检测和人脸检测。与标准智能功能相比,大华Analytics+算法显著提高了准确性和可靠性。该摄像机非常适合各种不同的应用-Night Color Technology和超宽动态范围使得摄像机能够在任何光照条件下运行,并且IP67评级使得摄像机适用于最恶劣的环境下。

功能

周界保护
大华Analytics+包括线圈和入侵功能,提供基于物体类型的自定义线圈,用于自动化有限访问区域。周界保护需要更少的像素来检测物体,以提供更高的准确性和由于光线、天气、树木或动物引起的虚假警报减少。

人流量统计
该摄像机使用复杂的实时人流量统计算法,从两个不同的人流量统计功能中提供准确的流量统计数据,即线交叉和区域。线交叉功能计算穿越定义线的人数,区域功能计算特定用户定义区域内的人数。人流量统计非常适用于测量进出地点的客户数量,并监控特定区域的人群。

智能运动检测+
智能运动检测+是大华Analytics+技术的组成部分,可以提高报警准确性,减少虚假报警的次数。高级的SMD+算法分析场景中的人体或车辆运动,同时滤除由树木、叶子、动物、天气引起的其他运动,并在检测到时触发警报。SMD+还通过过滤虚假警报节省了搜索录制视频的时间,并允许快速检索由于人或车引起的警报。

夜间彩色技术
夜色摄像机集成了白光LED,可在完全黑暗的情况下提供全彩图像,同时也是一种有效的视觉威慑力。这项技术提供智能照明,摄像机在环境光线下降时自动激活白光照明器,并调整曝光时间和LED强度,以防止过度曝光图像。
