style="text-indent:25px">防爆攝像頭的鏡頭：鏡頭是攝像機用來抓取畫面的工具，不同的鏡頭得到的畫面大小和效果也不一樣。常用的鏡頭種類包括：手動/自動光圈定焦鏡頭和自動光圈變焦鏡頭兩種。定焦鏡頭分為標準鏡頭和廣角鏡頭兩種。定焦鏡頭的適用范圍為：1.手動光圈鏡頭：所需監(jiān)視的環(huán)境照度變化不大，如室內。2.自動光圈鏡頭：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.標準鏡頭：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：手動變焦和電動變焦(電動光圈和自動光圈)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)格不應小于攝像機的規(guī)格，也就是說1/2〃的鏡頭可以與1/3〃的攝像機一起使用，但是1/3〃的鏡頭就不能夠在1/2〃的攝像機上使用。車載防爆球機廠家防爆紅外攝像機畫面不清晰解決：用萬用表測試電壓與電流大小，確保紅外燈正常工作。</p><div

style="text-indent:25px">防爆攝像機用電安全需注意什么？防爆攝像機屬于防爆監(jiān)控類產品，是防爆行業(yè)跟監(jiān)控行業(yè)的交叉產物，因為在具有高?？扇夹浴⑽ｋU性現(xiàn)場不能使用常規(guī)的攝像產品，需要具有防爆功能且有國家**機構頒發(fā)的相關證書的產品才能稱得上是防爆攝像機。由于用電過程中要產生電弧、電火花等危險因素，因臨時用電屬于安全防火的重要管理內容之一。凡是在危險環(huán)境臨時用電，必須采取措施，達到整體防爆要求。臨時用電一般是緊急搶修、設備異常處理、改造項目和生產裝置接軌等。而且常常是一邊生產、一邊施工，現(xiàn)場條件苛刻，加上有些電器和電動工具還沒有達到整體防爆的要求。我國對火災和危險環(huán)境的臨時施工用電還沒有詳細規(guī)定。為此，有必要研究和探討在火災危險環(huán)境、臨時用電達不到整體防爆要求的情況下，如何保證安全生產。防爆監(jiān)控攝像機使用：IIA類：汽油、燃料油、煤油、柴油、戊醇、已醇。</p><div

style="text-indent:25px">防爆攝像頭的防護：實際應用中雷電防護并不能普及存在著多方面的原因。一方面，很多甲方對系統(tǒng)雷電防護認識不足，意識不到雷電防護設計對整個系統(tǒng)的重要性，受限制于工程造價;另一方面，有些工程商也不是很重視系統(tǒng)的雷電防護，因為如果考慮了這方面要求就會提高工程報價，影響競標時的價格優(yōu)勢;如此一來，系統(tǒng)的安全性和有效性就會存在極大隱患。不光光是戶外的攝像機會受到雷電的損壞，視頻監(jiān)控中心機房內的設備也會由于雷電的襲擊而遭到“傷害”。那么，防爆監(jiān)控設備如何防雷呢?一般來說，防爆視頻監(jiān)控系統(tǒng)分為前端攝像、中間傳輸、后端視頻監(jiān)控中心幾部分。咸陽高清防爆紅外攝像機哪家好</p></p><br
