style="text-indent:25px">防爆紅外攝像機(jī)畫面不清晰的原因：1、內(nèi)置的是低劣攝像機(jī)，照度極高。很多工廠為了在同樣的紅外燈輔光前提下獲得更亮的圖像，人為的調(diào)高CCD的靈敏度。因?yàn)楹芏嗌a(chǎn)商為了價(jià)格競爭，使用非常低劣的攝像機(jī)內(nèi)置里面，這種攝像機(jī)在紅外燈補(bǔ)光不足的情況下，為提到更亮，于是人為調(diào)高CCD的增益靈敏度，跟我們在硬盤錄像機(jī)上調(diào)高亮度一樣，是極易出現(xiàn)雪花現(xiàn)象的。2、可能是在室外比較多灰塵的環(huán)境下。特別是在野外，就有可能是攝像機(jī)里的紅外燈把肉眼看不到的細(xì)小顆粒拍出來了，這在白天紅外燈不開啟的情況下，肉眼及攝像機(jī)感覺不明顯的，這種現(xiàn)象是環(huán)境使然。產(chǎn)生雪花點(diǎn)多的原因比較多，但辦法總比困難多。只要發(fā)現(xiàn)了真實(shí)的原因所在，解決起來就簡單多了，只要你愿意花成本，花時(shí)間。紅外二極管電流過小，將影響其輻射功率的發(fā)揮。棗莊球形防爆紅外攝像機(jī)</p><p

style="text-indent:25px">提高防爆攝像機(jī)夜視效果的方法：1、直接使用排220V電源線到防爆攝像頭端，使用小型12V的開關(guān)電源供電;該方案布線麻煩、但電源線線徑可以較細(xì)，需使用比較好的DC12V的適配器，千萬不要使用劣質(zhì)適器。2、集中供電端使用DV24-48V的開關(guān)電源，通過網(wǎng)線進(jìn)行供電，到前端加降壓模塊降低為DC12V使用。該方案需要有一定的電路基礎(chǔ)，成本低，可靠性也比較高。3、使用線徑較粗的電源線給前端進(jìn)行直流集中供電。該方案電源線比較粗，線路成本比較高。4、距離不算太長的，如30M，可使用4-5及7-8線對來傳輸DC12V，這樣傳輸線截面積增加了一倍，能明顯改善供電質(zhì)量。該方案使用得當(dāng)?shù)脑挘C合效益比較高?，F(xiàn)在市場上已有的防爆攝像頭除了具備正常的監(jiān)控圖像捕捉功能外，其實(shí)并非以清晰度取勝，重要的是通過圖像獲取位置，這可以通過熱成像技術(shù)捕捉移動目標(biāo)，這種激光紅外增強(qiáng)融合技術(shù)，達(dá)到了在零光線下的圖像捕捉，具備了對"發(fā)熱物"的追蹤，很好地完成了數(shù)據(jù)抓取作用。延安球形防爆紅外攝像頭</p></p><br
