style="text-indent:25px">防爆攝像頭的原理與選用：就防爆攝像頭本身而言，光電結(jié)構(gòu)和普通的工業(yè)攝像機(jī)并無(wú)本質(zhì)上的差異。其特征在于使用一種或一種以上的防爆型式對(duì)工業(yè)攝像機(jī)進(jìn)行處理，使之能夠在易燃易爆的現(xiàn)場(chǎng)環(huán)境中應(yīng)用。早期的防爆攝像頭以本質(zhì)安全型和正壓型為主。本質(zhì)安全型防爆攝像頭的特點(diǎn)在于對(duì)攝像機(jī)的電路進(jìn)行本質(zhì)安全處理，電氣之線路輸出或輸入均被設(shè)計(jì)控制在不足以產(chǎn)生使氫氣發(fā)生引火危險(xiǎn)的能量以下，使其在正常工作中不會(huì)產(chǎn)生電火花、電弧及高溫，從而避免引起危險(xiǎn)易爆物質(zhì)。這種類型的防爆攝像頭結(jié)構(gòu)單位成本過(guò)高是較大缺點(diǎn)，此外也不利于日后的升級(jí)。正壓型是早期美系防爆攝像頭產(chǎn)品的常用結(jié)構(gòu)，使用中維護(hù)相當(dāng)不便，如不精心維護(hù)，引起危險(xiǎn)性相當(dāng)大。此結(jié)構(gòu)目前所見(jiàn)除極少數(shù)某地廠商仍在制造外，基本已被防爆攝像頭行業(yè)較全淘汰。</p><p style="text-indent:25px">安全監(jiān)控是城市生活的一大主題，也是社會(huì)生產(chǎn)的必要管理手段。在我們的周圍監(jiān)控生活中，紅外監(jiān)控給我們帶來(lái)的平安，是當(dāng)前夜間監(jiān)控中的主流，但它也特性也給我們帶來(lái)了很多的煩惱。說(shuō)到給我們的幫助，它的易用性，實(shí)用性，隱蔽性是夜間監(jiān)控的好幫手。但是，就在我們即將將重要的任務(wù)托付給他的時(shí)候，它的短命，紅暴，距離等不利運(yùn)用的因素，這些將會(huì)隨著技術(shù)的發(fā)展，這些問(wèn)題會(huì)慢慢的解決，但目前，這些問(wèn)題還是存在的，所以用戶在購(gòu)買時(shí)，就要分清這些存在的問(wèn)題，在工業(yè)生產(chǎn)中，防爆監(jiān)控的紅外運(yùn)用是很普遍的，紅外技術(shù)也是監(jiān)控領(lǐng)域的較前沿，因?yàn)?，工業(yè)安全生產(chǎn)的監(jiān)控要求很為嚴(yán)格，審核的標(biāo)準(zhǔn)也很高，客戶的要求也相對(duì)苛刻，所以，一般的防爆紅外攝像機(jī)的紅外性能要優(yōu)于一般的紅外監(jiān)控?cái)z像機(jī)。防爆攝像頭的防護(hù)：室外的設(shè)備需要考慮防止直擊雷擊。</p><div

style="text-indent:25px">防爆攝像頭的鏡頭：鏡頭是攝像機(jī)用來(lái)抓取畫(huà)面的工具，不同的鏡頭得到的畫(huà)面大小和效果也不一樣。常用的鏡頭種類包括：手動(dòng)/自動(dòng)光圈定焦鏡頭和自動(dòng)光圈變焦鏡頭兩種。定焦鏡頭分為標(biāo)準(zhǔn)鏡頭和廣角鏡頭兩種。定焦鏡頭的適用范圍為：1.手動(dòng)光圈鏡頭：所需監(jiān)視的環(huán)境照度變化不大，如室內(nèi)。2.自動(dòng)光圈鏡頭：所需監(jiān)視的環(huán)境照度變化大，如室外。3.廣角鏡頭：監(jiān)視的角度較寬，距離較近。4.標(biāo)準(zhǔn)鏡頭：監(jiān)視的角度和距離適中。變焦鏡頭分為10倍、6倍和2倍變焦鏡頭，另一種分法是：手動(dòng)變焦和電動(dòng)變焦(電動(dòng)光圈和自動(dòng)光圈)兩種。變焦鏡頭在規(guī)則上可以劃分為：1/3〃、1/2〃和1〃等。選擇變焦鏡頭的原則是：鏡頭的規(guī)格不應(yīng)小于攝像機(jī)的規(guī)格，也就是說(shuō)1/2〃的鏡頭可以與1/3〃的攝像機(jī)一起使用，但是1/3〃的鏡頭就不能夠在1/2〃的攝像機(jī)上使用。防爆紅外攝像機(jī)畫(huà)面不清晰解決：紅外燈不好，再好的電流也沒(méi)有用。蘭州高清防爆監(jiān)控?cái)z像頭</p><p
