openwrt 挂载 UVC摄像头
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            #免驱摄像头
opkg install kmod-video-gspca-zc3xx    #中微星摄像头 如zc301 zc303 zc305
opkg install kmod-i2c-core
opkg install kmod-input-core 
opkg install motion

摄像头用motion做监控非常棒！

画面上只要有变化，就会保存照片到置顶位置。太适合做监控了

我在三个路由实现了该监控,分别是mi424wr,db120,7231-4p.其中7231-4p是使用dd-wrt 其余两个使用openwrt-backfire.
首先在http://downloads.openwrt.org/backfire/10.03   根据硬件平台下载安装motion及相关的ipk包,
然后编辑vi /overlay/etc/motion.conf, 我的编辑文件内容如下
# Rename this distribution example file to motion.conf
#
# This config file was generated by motion "3.2.11.1"

############################################################

# Motion Detection Settings:
############################################################

threshold 1500 这个是改变探测灵敏度,越小越灵敏
# Automatically tune the threshold down if possible (default: off)
threshold_tune off

# Noise threshold for the motion detection (default: 32)
noise_level 32

# Automatically tune the noise threshold (default: on)

# Live Webcam Server

# Restrict webcam connections to localhost only (default: on)
webcam_localhost off #必须改成off才能通过pc访问

# 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

##############################################################
# 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   #如果有多个摄像头要把使用这部分,否则全部注释掉

因为字符限制,上面只是把需要修改的地方写上了
修改好后,在/etc目录下 输入 motion -c motion.conf

这时候只要摄像头画面有变化,就出现采集图片到设置目录了.

在windows下也可以使用palantir (在这里下载http://www.fastpath.it/products/palantir/pub/pclient.exe) 的pc客户端 连接 192.168.1.1:8081就可以看到图片了,这个完全是一张张图片播放的 所以不连贯.

openwrt 挂载ZCXX摄像头

1、先修改opkg源为openwrt.cn， 安装openwrt.cn中文网提供的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
