openwrt 挂载 UVC摄像头
opkg update
opkg install kmod-usb-video
opkg install kmod-video-gspca-core
opkg install kmod-video-core
opkg install kmod-video-uvc
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:

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

# Automatically tune the noise threshold (default: on)

##############################################################
# 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.


dmesg | grep uvcvideo

spcacat
libpthread
libmjpg


opkg install usbutils
lsusb
dmesg | grep usb

cat /dev/video0 > /tmp/1.jpg


Palantir 、motion、Mjpg-streamer




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/downlo ... 2.10-1_brcm63xx.ipk
opkg install kmod-video-core
opkg install http://www.openwrt.org.cn/downlo ... 2.10-1_brcm63xx.ipk
opkg install http://downloads.x-wrt.org/xwrt/ ... 2.10-1_brcm63xx.ipk
