style="text-indent:25px">防爆監(jiān)控攝像機使用中的問題：1、監(jiān)控設(shè)備維護應(yīng)注意以下幾點：（1）對每個防爆攝像機所供電源的插座要經(jīng)常檢查，防止插頭脫落。（2）保證對每個防爆監(jiān)控攝像機和監(jiān)控中心的供電電壓較恒定。（3）對低矮位置的防爆攝像機盡量設(shè)有明顯標(biāo)志，提醒非監(jiān)控管理人觸碰。（4）對監(jiān)控中心的監(jiān)控控制設(shè)備派專人管，要求非監(jiān)控人員禁止操作。（5）監(jiān)控中心在每晚無人的情況下一定要對監(jiān)控設(shè)備斷電。（6）對監(jiān)控設(shè)備經(jīng)常擦試保養(yǎng)。2、新安裝的防爆云臺使用后不久就運轉(zhuǎn)不靈或根本不轉(zhuǎn)動。這種情況的出現(xiàn)除云去產(chǎn)品質(zhì)量的因素外，一般是以下三種原因造成的：（1）只允許將防爆監(jiān)控攝像機正裝的防爆云臺，在使用時采用了吊裝的方式。在這種情況下，吊裝方式導(dǎo)致防爆云臺運轉(zhuǎn)負(fù)荷加大，故使用不久就會導(dǎo)致防爆云臺的轉(zhuǎn)動機構(gòu)損壞，甚至燒毀電機。（2）防爆監(jiān)控攝像機及其防護罩等總重量超過防爆云臺的承重。特別是室外使用的防爆云臺，往往防護罩的重量過大，常會出現(xiàn)防爆云臺轉(zhuǎn)不動（特別是垂直方向轉(zhuǎn)不動）的問題。（3）室外防爆云臺因環(huán)境溫度過高、過低、防水、防凍措施不良而出現(xiàn)故障甚至損壞。</p><p style="text-indent:25px">防爆攝像機在什么檔次呢？視頻信號的標(biāo)稱值為1Vp-p，標(biāo)準(zhǔn)值為0.7Vp-p，較低照度時的視頻信號值為1/3到1/2的標(biāo)準(zhǔn)植。所以防爆攝像機在較低照度時的圖像，決不會“如同白晝一樣”。另外，防爆攝像機在較低照度時產(chǎn)生的圖像清晰度，是用電視信號測試卡進(jìn)行測式的，其黑白相間的條紋，要求黑色反射率近于0%，白色反射率大于89.9%。而我們在現(xiàn)場觀察時有時不具備這樣的條件，比如：樹葉和草地的反射率很低，反差很小，就不易獲得清晰圖像。因此實際使用當(dāng)中不能以防爆攝像機標(biāo)稱的較低照度作為衡量現(xiàn)場環(huán)境照度的標(biāo)準(zhǔn)。防爆攝像機維護：每月定期對防爆監(jiān)控系統(tǒng)和設(shè)備進(jìn)行優(yōu)化。</p><div

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(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(yīng)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。裝置區(qū)、油罐區(qū)等區(qū)域的井道、坑、電纜溝和蒸氣管溝等處所都有沉積性氣體。咸陽耐高溫防爆攝像頭哪家好</p><p
