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(xiàn)到防爆攝像頭端，使用小型12V的開(kāi)關(guān)電源供電;該方案布線(xiàn)麻煩、但電源線(xiàn)線(xiàn)徑可以較細(xì)，需使用比較好的DC12V的適配器，千萬(wàn)不要使用劣質(zhì)適器。2、集中供電端使用DV24-48V的開(kāi)關(guān)電源，通過(guò)網(wǎng)線(xiàn)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(xiàn)徑較粗的電源線(xiàn)給前端進(jìn)行直流集中供電。該方案電源線(xiàn)比較粗，線(xiàn)路成本比較高。4、距離不算太長(zhǎng)的，如30M，可使用4-5及7-8線(xiàn)對(duì)來(lái)傳輸DC12V，這樣傳輸線(xiàn)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?huà)，綜合效益比較高?，F(xiàn)在市場(chǎng)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(guò)圖像獲取位置，這可以通過(guò)熱成像技術(shù)捕捉移動(dòng)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(xiàn)下的圖像捕捉，具備了對(duì)"發(fā)熱物"的追蹤，很好地完成了數(shù)據(jù)抓取作用。青島耐高溫防爆紅外攝像機(jī)哪家好監(jiān)控端的避雷措施應(yīng)慎重，要考慮各種可能類(lèi)型的雷擊入侵、對(duì)地環(huán)路電位差現(xiàn)象及電力供應(yīng)突波等保護(hù)措施。</p><div

style="text-indent:25px">防爆攝像機(jī)：防爆攝像機(jī)能夠用在易燃易爆等危險(xiǎn)場(chǎng)所，如煤礦、石油廠(chǎng)、油庫(kù)、花炮廠(chǎng)等。防爆攝像機(jī)的攝像部分一般安裝在現(xiàn)場(chǎng),它包括攝像機(jī)、鏡頭、防爆護(hù)罩、支架和電動(dòng)云臺(tái)。它的作用是對(duì)監(jiān)視區(qū)域進(jìn)行攝像并將其轉(zhuǎn)換成電信號(hào)。防爆攝像機(jī)分為彩色和黑白兩種，一般黑白攝像機(jī)要比彩色的靈敏度高，比較適合用于光線(xiàn)不足的地方，彩色攝像機(jī)可以增加紅外效果以實(shí)現(xiàn)夜間監(jiān)控，光線(xiàn)暗時(shí)紅外燈自動(dòng)開(kāi)啟實(shí)現(xiàn)彩色和黑白轉(zhuǎn)換，如果使用的目的只是監(jiān)視景物的位置和移動(dòng)，可采用黑白攝像機(jī)；如果要分辨被攝像物體的細(xì)節(jié)，比如分辨衣服和景物的顏色，則采用彩色的比較好。防爆攝像機(jī)的規(guī)格可分為1/3〃、1/2〃和2/3〃等，安裝方式有固定和可轉(zhuǎn)動(dòng)的帶防爆云臺(tái)二種。提高防爆攝像機(jī)夜視方法：集中供電端使用DV24-48V的開(kāi)關(guān)電源，通過(guò)網(wǎng)線(xiàn)進(jìn)行供電。</p><div
