style="text-indent:25px">防爆攝像頭的防護：實際應(yīng)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(shè)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(nèi)的設(shè)備也會由于雷電的襲擊而遭到“傷害”。那么，防爆監(jiān)控設(shè)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。防爆紅外攝像機畫面不清晰的原因：內(nèi)置的是低劣攝像機，照度極高。</p><div
