openwrt 挂载摄像头

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"

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

# Daemon

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

# Start in daemon (background) mode and release terminal (default: off)
daemon off

# File to store the process ID, also called pid file. (default: not defined)

process_id_file /var/run/motion/motion.pid

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

# Basic Setup Mode

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

# Start in Setup-Mode, daemon disabled. (default: off)

setup_mode off

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

# Capture device options

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

# Videodevice to be used for capturing   (default /dev/video0)

# for FreeBSD default is /dev/bktr0
videodevice /dev/video0




# Image width (pixels). Valid range: Camera dependent, default: 352

width 320



# Image height (pixels). Valid range: Camera dependent, default: 288

height 240









# Motion Detection Settings:

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

# Threshold for number of changed pixels in an image that

# triggers motion detection (default: 1500)
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)

noise_tune on

# Live Webcam Server

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

# The mini-http server listens to this port for requests (default: 0 = disabled)
webcam_port 8081   #远程端口

# Quality of the jpeg images produced (default: 50)

webcam_quality 50

# Output frames at 1 fps when no motion is detected and increase to the

# rate given by webcam_maxrate when motion is detected (default: off)

webcam_motion off

# Maximum framerate for webcam streams (default: 1)

webcam_maxrate 1

# 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

webcam_limit 0

target_dir /tmp/cam1       #保存目录

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

# HTTP Based Control

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

# TCP/IP port for the http server to listen on (default: 0 = disabled)

control_port 8080

# Restrict control connections to localhost only (default: on)

control_localhost on

# Output for http server, select off to choose raw text plain (default: on)

control_html_output on

# Authentication for the http based control. Syntax username:password

# Default: not defined (Disabled)

; control_authentication username:password

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

# 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.

开机自启动

/etc/init.d/motion start     启动

/etc/init.d/motion enabel 是自启动

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/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
