首頁 > 業務范圍 > 樓宇對講

    樓宇對講即在樓宇建筑中起通話作用的一種設備,也稱可視門鈴。通俗的說,樓宇對講就是指你們家的門鈴系統,我們常說樓宇對講、可視門鈴、可視對講、對講門鈴等幾個詞語,都是同一個意思,即指一套訪客對講管理系統(一套包含軟件、硬件及售后服務的人性化管理訪客操作系統)。

    廣域網可視對講系統是在internet廣域網的基礎上構成的,數字室內機作為小區網絡中的終端設備起到兩個作用:
    一是利用數字室內機實現小區多方互通的可視對講;   
    二是通過小區以太網或互連網同網上任何地方的可視IP電話或PC之間實現通話。
    隨著整個產業步入良性循環,一個全新的寬帶數字產業鏈正逐步清晰, 基于寬帶的音頻、視頻傳輸和數據傳輸的數字產品是利用寬帶基礎延伸的新產品,它既包括寬帶網運營商和寬帶用戶駐地網接入商,未來以視頻互動為特征的寬帶網內容提供商、寬帶電視等下游產業也正在浮出?傊梢晫χv產品的發展的主要方向是數字化,數字化是可視對講系統發展的必由之路。
