15路則用千兆交換機(jī)。如果接 1080P 的網(wǎng)絡(luò)攝像機(jī)，一般 8 路圖像以內(nèi)，用百兆交換機(jī)，超過(guò) 8 路則用千兆交換機(jī)。網(wǎng)絡(luò)監(jiān)控中交換機(jī)的選擇一個(gè)合適的交換機(jī)，不*能夠發(fā)揮監(jiān)控網(wǎng)絡(luò)應(yīng)有的功能并能夠有效減少資源的浪費(fèi)。監(jiān)控網(wǎng)絡(luò)有三層架構(gòu)方式：中心層，鎮(zhèn)江視頻監(jiān)控系統(tǒng)廠家。匯聚層。接入層。以選用 720P 的攝像機(jī)為例，分別選擇對(duì)應(yīng)交換機(jī)。前端 20 路 720P 接入 1 個(gè)接入層交換機(jī)。接入層交換機(jī)的選擇：條件 1：攝像機(jī)碼流：4.5Mbps,20 個(gè)攝像機(jī)就是 20*4.5=90Mbps，鎮(zhèn)江視頻監(jiān)控系統(tǒng)廠家，也就是說(shuō)，接入層交換機(jī)上傳端口必須滿足 90Mbps/S 的傳輸速率要求,考慮到交換機(jī)實(shí)際傳輸速率(通常為標(biāo)稱值的 30%，100M 的也就 30 M 左右，鎮(zhèn)江視頻監(jiān)控系統(tǒng)廠家，)，所以接入層交換機(jī)應(yīng)選用具有 1000M 上傳口的交換機(jī)。閉路電視監(jiān)控系統(tǒng)因其能給人較直接的視覺(jué)、聽(tīng)覺(jué)感受，以及對(duì)被監(jiān)控對(duì)象的可視性、實(shí)時(shí)性及客觀性的記錄。鎮(zhèn)江視頻監(jiān)控系統(tǒng)廠家</p><div style="width:100%;text-align: center;"><img

style="text-indent:25px">閉路電視監(jiān)控系統(tǒng)其實(shí)是什么?閉路電視，英文翻譯 Closed-Circuit Television（CCTV），是一種只在固定的回路設(shè)備里播放信號(hào)的攝像機(jī)監(jiān)控系統(tǒng)，可讓您隨時(shí)監(jiān)控企業(yè)范圍和四周發(fā)生的事情。連接了監(jiān)控系統(tǒng)攝像機(jī)和監(jiān)視器，使您或保安人員可以實(shí)時(shí)查看發(fā)生的事件。監(jiān)控系統(tǒng)的另一個(gè)重要優(yōu)點(diǎn)是，可以將拍攝到的影像存檔作為記錄或證據(jù)以供日后使用或參考。監(jiān)控系統(tǒng)為何被稱為“閉路電視”？監(jiān)控系統(tǒng)為“封閉回路”的電視所以有別于普通的電視系統(tǒng)，因?yàn)樗纬闪艘粋€(gè)封閉的網(wǎng)絡(luò)，限制于指定范圍里鏡頭捕獲的信息。雖然也是點(diǎn)對(duì)點(diǎn)的無(wú)線連接，但 CCTV 監(jiān)控系統(tǒng)的信號(hào)不公開(kāi)傳輸，也不會(huì)接收公眾廣播的節(jié)目或內(nèi)容，因此不會(huì)受到外部廣播的干擾。監(jiān)控系統(tǒng)*接收和顯示來(lái)自安裝在現(xiàn)場(chǎng)的攝像頭影像，因此閉路電視一般是指用于廣播以外的電視，如工業(yè)電視、**電視、醫(yī)用電視、水下電視等。鎮(zhèn)江視頻監(jiān)控系統(tǒng)廠家作用是將攝像機(jī)輸出的視頻（有時(shí)包括音頻）信號(hào)饋送到中心機(jī)房或其他監(jiān)視點(diǎn)。</p><div
