openwrt 掛載 UVC攝像頭
opkg update
opkg install kmod-usb-ohci #一般BCM用的是ohci USB控制器
#opkg install kmod-usb-uhci #UHCI USB控制器
opkg install kmod-usb-video
opkg install kmod-video-gspca-core
opkg install kmod-video-core
opkg install kmod-video-uvc #免驅攝像頭
opkg install kmod-video-gspca-zc3xx #中微星攝像頭 如zc301 zc303 zc305
opkg install kmod-i2c-core
opkg install kmod-input-core
opkg install motion
攝像頭用motion做監控非常棒！
畫面上只要有變化，就會保存照片到置頂位置。太適合做監控了
我在三個路由實現了該監控,分別是mi424wr,db120,7231-4p.其中7231-4p是使用dd-wrt 其餘兩個使用openwrt-backfire.
首先在http://downloads.openwrt.org/backfire/10.03 根據硬件平臺下載安裝motion及相關的ipk包,
然後編輯vi /overlay/etc/motion.conf, 我的編輯文件內容如下
# Rename this distribution example file to motion.conf
#
# This config file was generated by motion "3.2.11.1"

# Threshold for number of changed pixels in an image that

threshold 1500 這個是改變探測靈敏度,越小越靈敏

# Automatically tune the noise threshold (default: on)

# Restrict webcam connections to localhost only (default: on)
webcam_localhost off #必須改成off才能通過pc訪問
# Limits the number of images per connection (default: 0 = unlimited)
# Number can be defined by multiplying actual webcam rate by desired number of seconds
# Actual webcam rate is the smallest of the numbers framerate and webcam_maxrate
webcam_limit 0

##############################################################
# Thread config files - One for each camera.
# Except if only one camera - You only need this config file.
# If you have more than one camera you MUST define one thread
# config file for each camera in addition to this config file.
##############################################################
# Remember: If you have more than one camera you must have one
# thread file for each camera. E.g. 2 cameras requires 3 files:
# This motion.conf file AND thread1.conf and thread2.conf.
# Only put the options that are unique to each camera in the
# thread config files.
thread /etc/thread1.conf
thread /etc/thread2.conf
# thread /etc/thread3.conf
# thread /etc/thread4.conf #如果有多個攝像頭要把使用這部分,否則全部註釋掉
因爲字符限制,上面只是把需要修改的地方寫上了
修改好後,在/etc目錄下 輸入 motion -c motion.conf
這時候只要攝像頭畫面有變化,就出現採集圖片到設置目錄了.
在windows下也可以使用palantir (在這裏下載http://www.fastpath.it/products/palantir/pub/pclient.exe) 的pc客戶端 連接 192.168.1.1:8081就可以看到圖片了,這個完全是一張張圖片播放的 所以不連貫.

openwrt 掛載ZCXX攝像頭
1、先修改opkg源爲openwrt.cn， 安裝openwrt.cn中文網提供的kmod-usb-video、kmod-video-gspca-core；
opkg update
opkg install
http://www.openwrt.org.cn/downloads/backfire/10.03/brcm63xx/packages/kmod-usb-video_2.6.32.10-1_brcm63xx.ipk
opkg install kmod-video-core
opkg install
http://www.openwrt.org.cn/downloads/backfire/10.03/brcm63xx/packages/kmod-video-gspca-core_2.6.32.10-1_brcm63xx.ipk
opkg install
http://downloads.x-wrt.org/xwrt/backfire/10.03/brcm63xx/packages/kmod-video-gspca-zc3xx_2.6.32.10-1_brcm63xx.ipk
