簡易監視系統DIY
最近單位內頻遭竊, 但預算有限, 專門的監視及防盜系統只能慢慢建立, 所以在此介紹建置一個簡單的監視系統.
硬體需求:
PC x 1
webcam x 1
感應式LED燈 x 1
軟體需求:
Java Runtime Environment (JRE) 6 or later.
DirectX 9 or later.
Windows Media Player 9 or later.
Windows 2000/XP/Vista/7/8/10
yawcam
webcam能連上PC, PC效能不拘能24hr開機即可.
慼應式LED燈的選擇應考量:
感應距離, eg. 3m
感應角度, eg. 270度
光通量(照度), eg. 900lm
夜間(或光線不足)時感應範圍內物體移動時亮燈一段時間, eg. 30s
兩腳扁型(一般家用)電源揗頭
目的是為1.提供webcam照明 2. 嚇阻小偷
webcam和感應式LED燈應該在NT$2000以內可以搞定.
yawcam軟體可在http://www.yawcam.com 網站免費download及使用.(Yawcam can be used for free both commercially and non-commercially.)
安裝好軟硬後, 接下來進行相關設定
yawcam會用到tcp/8888(http), tcp/udp/8081(stream), 請先設定好host and network firewall及router(設定port forward). (註: UPNP請參考http://www.yawcam.com/help/help_upnp.php)
若PC IP是dynamic, 請參考http://www.yawcam.com/help/noipguide.php
