一、可視對講系統是什么意思
可(ke)(ke)視(shi)(shi)對(dui)講系統是(shi)一套現代化的(de)(de)(de)小(xiao)(xiao)區(qu)(qu)住(zhu)宅服務措施,提供(gong)訪客與(yu)住(zhu)戶之間(jian)雙向(xiang)可(ke)(ke)視(shi)(shi)通話,達(da)到(dao)圖像、語音雙重識別(bie)的(de)(de)(de)效果,增加安全(quan)(quan)可(ke)(ke)靠(kao)性,同時節(jie)省(sheng)大量的(de)(de)(de)時間(jian),提高了(le)工(gong)作效率(lv)。更重要的(de)(de)(de)是(shi),一旦住(zhu)戶家內(nei)所安裝的(de)(de)(de)門磁開關、紅外報警(jing)探測(ce)(ce)器、煙霧探測(ce)(ce)器、瓦斯報警(jing)器等(deng)設(she)備,連接到(dao)可(ke)(ke)視(shi)(shi)對(dui)講系統的(de)(de)(de)保(bao)全(quan)(quan)型室內(nei)機上以后,可(ke)(ke)視(shi)(shi)對(dui)講系統就升(sheng)級為一個(ge)安全(quan)(quan)技(ji)術防(fang)(fang)范網絡,它(ta)可(ke)(ke)以與(yu)住(zhu)宅小(xiao)(xiao)區(qu)(qu)物業管理中心或小(xiao)(xiao)區(qu)(qu)警(jing)衛(wei)有線(xian)或無線(xian)通訊,從而起到(dao)防(fang)(fang)盜、防(fang)(fang)災、防(fang)(fang)煤氣泄漏等(deng)安全(quan)(quan)保(bao)護(hu)作用,為屋主的(de)(de)(de)生(sheng)命(ming)財產(chan)安全(quan)(quan)提供(gong)最大程度的(de)(de)(de)保(bao)障。它(ta)可(ke)(ke)提高住(zhu)宅的(de)(de)(de)整體管理和服務水平,創(chuang)造安全(quan)(quan)社區(qu)(qu)居住(zhu)環境,因(yin)此(ci)逐步成(cheng)為住(zhu)宅不可(ke)(ke)缺少(shao)的(de)(de)(de)配套設(she)備之一。
二、對講系統的種類有哪些
1、直按式對講系統
主(zhu)機上每(mei)(mei)個(ge)住(zhu)戶(hu)(hu)(hu)(hu)設置一個(ge)呼(hu)(hu)(hu)叫(jiao)按(an)鍵(jian),每(mei)(mei)個(ge)按(an)鍵(jian)通過呼(hu)(hu)(hu)叫(jiao)線(xian)(xian)(xian)(xian)與(yu)相對(dui)(dui)應的住(zhu)戶(hu)(hu)(hu)(hu)連(lian)接(jie)(jie)。直(zhi)接(jie)(jie)按(an)該住(zhu)戶(hu)(hu)(hu)(hu)呼(hu)(hu)(hu)叫(jiao)鍵(jian)即可直(zhi)接(jie)(jie)呼(hu)(hu)(hu)叫(jiao)住(zhu)戶(hu)(hu)(hu)(hu),直(zhi)觀好用,但無(wu)保密功能(neng)。該類(lei)樓(lou)宇對(dui)(dui)講(jiang)系(xi)(xi)統的連(lian)接(jie)(jie)系(xi)(xi)統,除了送話線(xian)(xian)(xian)(xian)、受話線(xian)(xian)(xian)(xian)、地線(xian)(xian)(xian)(xian)三根(gen)共用線(xian)(xian)(xian)(xian)外,每(mei)(mei)個(ge)住(zhu)戶(hu)(hu)(hu)(hu)需要一根(gen)呼(hu)(hu)(hu)叫(jiao)連(lian)接(jie)(jie)線(xian)(xian)(xian)(xian),如該樓(lou)有20個(ge)住(zhu)戶(hu)(hu)(hu)(hu),則需要20根(gen)呼(hu)(hu)(hu)叫(jiao)線(xian)(xian)(xian)(xian)。該類(lei)呼(hu)(hu)(hu)叫(jiao)系(xi)(xi)統主(zhu)機成本較低,但連(lian)接(jie)(jie)系(xi)(xi)統成本較高,且電路連(lian)接(jie)(jie)線(xian)(xian)(xian)(xian)較多,連(lian)接(jie)(jie)復雜。
2、數碼式對講系統
在主(zhu)(zhu)(zhu)機(ji)上設置0~9十個數位按鍵,內置編碼(ma)(ma)(ma)(ma)識別(bie)系(xi)統,每個住戶(hu)(hu)設置一(yi)組數位編碼(ma)(ma)(ma)(ma),輸(shu)入(ru)(ru)該(gai)住戶(hu)(hu)的(de)(de)密(mi)(mi)碼(ma)(ma)(ma)(ma),才能呼(hu)叫(jiao)該(gai)戶(hu)(hu),假如(ru)不知道該(gai)戶(hu)(hu)編碼(ma)(ma)(ma)(ma),無法呼(hu)叫(jiao),具(ju)有一(yi)定(ding)的(de)(de)保密(mi)(mi)功能,避免用(yong)(yong)戶(hu)(hu)被無端(duan)打(da)攪。該(gai)類對講(jiang)系(xi)統全部使(shi)用(yong)(yong)者通過一(yi)根(gen)呼(hu)叫(jiao)共用(yong)(yong)線即(ji)可與主(zhu)(zhu)(zhu)機(ji)連(lian)接,輸(shu)入(ru)(ru)數位后,編碼(ma)(ma)(ma)(ma)系(xi)統識別(bie)后呼(hu)叫(jiao)相應的(de)(de)用(yong)(yong)戶(hu)(hu)。該(gai)類樓宇對講(jiang)系(xi)統主(zhu)(zhu)(zhu)機(ji)成(cheng)本較高,但(dan)連(lian)接系(xi)統連(lian)接線少,成(cheng)本低(di),只需(xu)要呼(hu)叫(jiao)線、送話(hua)線、受話(hua)線、地線四根(gen)共用(yong)(yong)線。
3、可視對講系統
可(ke)視(shi)(shi)(shi)對講(jiang)系統(tong)(tong)(tong)分直按式可(ke)視(shi)(shi)(shi)對講(jiang)系統(tong)(tong)(tong)和數碼式可(ke)視(shi)(shi)(shi)對講(jiang)系統(tong)(tong)(tong),除主機(ji)上(shang)設置(zhi)攝像、分機(ji)上(shang)設置(zhi)顯像器(qi)材(cai)外,系統(tong)(tong)(tong)連(lian)接在上(shang)述1、2類(lei)連(lian)接線的基礎上(shang),還需增加視(shi)(shi)(shi)訊(xun)訊(xun)號連(lian)接線或視(shi)(shi)(shi)頻放(fang)大器(qi),每個(ge)使(shi)用(yong)者還需增加一個(ge)視(shi)(shi)(shi)頻顯示用(yong)的小電源(yuan)。
