[廣告]複合式 WIFI wireless VIDEO SERVER

將UVC CVBS Grabber card 連接至 WIFI 無線分享 伺服器  就變成  1CH wireless  WIFI Video Server

專業的監控設備在意的是Security , 但相對的安裝就不容易..通常需要有系統整合廠商到府安裝

我做的產品有別於專業的的監控設備,我在意的是安裝容易度,

目的是要讓消費者自己也可以安裝...

至於有沒有 "Security "等級,這就見仁見智....

好比說, 專業的"Security "玩家會認為, 攝影機的低照度 寬動態, 壓縮率,Dual stream 等等很重要...

但我的目標市場不是專業的玩家....

我這個玩意是可以讓一般的Webcam 或一般的類比攝影機變成可以"居家監看" 的DIY 產品..

Webcam 當然不會在意低照度 寬動態等監控等級要求。 但好處是,隨手可得,隨手都買得到.. 

很容易自己DIY

這個WIFI Video Server 除了當 Video Server 之外,還可以個別使用，以下是使用方式介紹

1.  ①UVC CVBS Grabber card + ②WIFI 無線分享伺服器  = 1CH WIFI Video Server (無線影音伺服器)

2. ①UVC  CVBS Grabber card 單獨使用

3. ②WIFI  無線分享伺服器 + Webcam  = WIFI IP Camera  / Baby Monitor

c.  the placed away from the walls and railings.

    The best location of  antenna is open void (wide spacious)
   ( in my video demo, it is not 100% spacious and empty-void.)

  in my test environment, it  is not good
