[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

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

[廣告]硬體工程師有福了!! 可以在IPAD/IPHONE 顯示的WIFI wireless 電子顯微鏡

Wireless Microscope~~~~

公司裡面的硬體工程師是最辛苦的...

版子越做越小,IC 的腳位也越來越小...

硬體工程師的眼力也要越來越好....

長期觀看硬體版子線路,可能眼睛會拖窗....

本人目前已經完成一款複合式的 WIFI 電子顯微鏡,

可以透過智慧手機或平版電腦來監看硬體線路圖.....

在無線網路室內 50公尺範圍內,至少可以同時提供 50人同時監看,

↓IPAD 直接透過內鍵的瀏覽器 SAFARI 就可以直接觀看...
透過 WIFI 的 SSID 主動丟IP, 可同時讓 PC 及 IPAD 至少50人同時觀看
