href='http://www.marketresearchvista.com/' target='_blank' class='key_tag'><font color=#136ec2><strong>網絡高清攝像頭</strong></font></a>，說到它讓人想到的是監控攝像頭，也就是公安或是派出所常叫的天眼，解決了很多的安全問題，讓人們的生活生產多了更多的保障，當下越來越多的家庭都安裝了監控，讓家里的每個動態都隨時掌握。當下那么多的網絡攝像頭銷售店或是網上商城，你知道怎么怎么判斷一款網絡攝像頭的好壞嗎？</span></p><p style="line-height: 2em; text-indent: 2em;"><span style="font-family: 微軟雅黑, "Microsoft YaHei"; font-size: 14px;">一、像素值</span></p><p style="line-height: 2em; text-indent: 2em;"><span style="font-family: 微軟雅黑, "Microsoft YaHei"; font-size: 14px;">網絡攝像頭同手機相機一樣，像素越高，則圖像分辨率越高、越清晰，因此，想要一個高清晰度的顯示畫面首先要看像素。</span></p><p style="line-height: 2em; text-indent: 2em;"><span style="font-family: 微軟雅黑, "Microsoft YaHei"; font-size: 14px;">二、水平分辨率</span></p><p style="line-height: 2em; text-indent: 2em;"><span style="font-family: 微軟雅黑, "Microsoft YaHei"; font-size: 14px;">網絡攝像頭水平清晰度，像素值和水平分辨率都是衡量畫面清晰度的主要指標。一般情況下，只有水平清晰度指標超過1080P和720P的才可稱為高清成像，所以在選購的時候注意這一點。</span></p><p style="text-align:center"><span style="font-family: 微軟雅黑, "Microsoft YaHei"; font-size: 14px;"><img src="/data/upload/image/20160623/1466667302380098.jpg" alt="網絡攝像頭" width="500" height="259" border="0" vspace="0" title="網絡攝像頭" style="width: 500px; height: 259px;"/></span></p><p style="line-height: 2em; text-indent: 2em;"><span style="font-family: 微軟雅黑, "Microsoft YaHei"; font-size: 14px;">三、Z低照度</span></p><p style="line-height: 2em; text-indent: 2em;"><span style="font-family: 微軟雅黑, "Microsoft YaHei"; font-size: 14px;">網絡攝像頭Z低照度就是監控攝像機能在多黑的條件下看到圖像，它的成像效果與鏡頭的光圈的大小有關。</span></p><p style="line-height: 2em; text-indent: 2em;"><span style="font-family: 微軟雅黑, "Microsoft YaHei"; font-size: 14px;">四、攝像靶面</span></p><p style="line-height: 2em; text-indent: 2em;"><span style="font-family: 微軟雅黑, "Microsoft YaHei"; font-size: 14px;">網絡攝像頭用英寸來表示，是圖像傳感器的對角長度。靶面的尺寸越小技術含量就越高，通過應用試驗，1/2英寸的則有更多的通光量，1/4英寸的器件則會有更大的景深，這個要根據安裝場所的監控環境來確定。</span></p><p style="line-height: 2em; text-indent: 2em;"><span style="font-family: 微軟雅黑,
