style="text-indent:25px">防爆攝像機(jī)的安裝：室內(nèi)安裝：多數(shù)的傳統(tǒng)方式是將建筑出入口的監(jiān)控防爆攝像機(jī)安裝在室內(nèi)。這種方式的優(yōu)點(diǎn)是可選擇監(jiān)控方向安裝（同一幢樓建筑內(nèi)應(yīng)考慮監(jiān)控方向的一致性和封閉性，以保證任何一個(gè)進(jìn)入建筑的人員均可在某一出入口留下面部正面圖像）。同時(shí)此種方式安裝簡(jiǎn)便，布線簡(jiǎn)單，便于維護(hù)。需要注意的是在監(jiān)控防爆攝像機(jī)的選擇及安裝位置上要考慮室外光源對(duì)監(jiān)控防爆攝像機(jī)的影響。如果監(jiān)控防爆攝像機(jī)視場(chǎng)朝室外安裝，則要選擇帶自動(dòng)光圈，背光補(bǔ)償較強(qiáng)的監(jiān)控防爆攝像機(jī)。對(duì)復(fù)雜光照環(huán)境的出入口則要選用寬動(dòng)態(tài)攝像、強(qiáng)光壓制監(jiān)控防爆攝像機(jī)，甚至是增加補(bǔ)充光源。</p><p style="text-indent:25px">防爆攝像頭的鏡頭：鏡頭是攝像機(jī)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(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)不清晰解決：采用雙濾光片或者雙玻璃結(jié)構(gòu)，提高晚上紅外燈的攝入程度和避免水霧影響鏡頭。</p><div

style="text-indent:25px">防爆攝像機(jī)：目前防爆攝像機(jī)的市場(chǎng)競(jìng)爭(zhēng)非常激烈，雖然我們可以通過防爆等級(jí)和國(guó)家認(rèn)證等級(jí)來認(rèn)定某種防爆攝像機(jī)是否滿足自己的要求，但是有很多廠家經(jīng)常打著牌子的幌子，以次充好，拿著價(jià)格來誤導(dǎo)客戶，使很多工程商上當(dāng)受騙。因此在這里，小編提醒各位有意購(gòu)買防爆攝像機(jī)的客戶們要擦亮眼睛，驗(yàn)證產(chǎn)品的等級(jí)合格證，多查看關(guān)于產(chǎn)品的評(píng)論，看自身比較適合哪個(gè)等級(jí)的產(chǎn)品，一般來說，肯定是等級(jí)越高，防爆性能越好，價(jià)格也就越高。防爆攝像機(jī)解析度技術(shù)分析：說到防爆攝像機(jī)，衡量解析度的像素、線數(shù)和清晰度這幾個(gè)參數(shù)就不可避免的要涉及到。然而很多工程商們?cè)谫?gòu)買防爆攝像機(jī)的時(shí)候?qū)@三個(gè)參數(shù)根本就無法搞清楚，有的人甚至連它們的概念都不知道。這也無可厚非，因?yàn)楹芏喙?yīng)商在提供產(chǎn)品給工程商時(shí)，大家由于時(shí)間的問題，再加上參數(shù)之間關(guān)系與產(chǎn)品交易并沒有多大影響，因此供應(yīng)商和工程商一般只大概交涉像素的多少而已，而不會(huì)涉及到像素、線數(shù)和清晰度的關(guān)系問題。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。無線防爆紅外攝像機(jī)哪家好</p><p style="text-indent:25px">防爆紅外攝像機(jī)畫面不清晰解決：可能其攝像機(jī)的照度極高，而在室外光亮度不高的情況，極易出現(xiàn)雪花。無線防爆紅外攝像機(jī)哪家好</p><p style="text-indent:25px">防爆攝像機(jī)的結(jié)構(gòu)：近紅外指波長(zhǎng)為0.75～3.0微米；中紅外指波長(zhǎng)為3.0～20微米；遠(yuǎn)紅外則指波長(zhǎng)為20～1000微米。由于紅外光屬于非可見光，肉眼無法看見它在空間的存在，因此以一種能發(fā)射紅外光的LED二極管紅外燈主動(dòng)發(fā)射紅外光的形式被大量使用于要求具有隱蔽性的夜視監(jiān)控中，代替?zhèn)鹘y(tǒng)隱蔽性低的照明燈夜視監(jiān)控。紅外燈有不同的功率及715、850nm兩種波長(zhǎng)，波長(zhǎng)的不同決定了紅外燈照距和效果。防爆紅外攝像機(jī)主要由紅外燈板、鏡頭及攝像主板，還有防爆護(hù)罩構(gòu)成。各構(gòu)成部分在防爆紅外攝像機(jī)工作過程中都擔(dān)負(fù)者重要的作用。無線防爆紅外攝像機(jī)哪家好</p></p><br
