如何用树莓派部署摄像头

首先你需要将摄像头,怼进去,然后就可以试着在树莓派的debian类似系统用apt-get进行获取网络摄像头软件motion

  • motion的使用方法
    首先我们通过apt-get install 可以安装motion,motion这款软件我们在这里也提及一下,是用于内外网监控的一个软件,它会启动8366端口作为我们的内网查看端口,网上有许多对树莓派安装motion的介绍,这里不细说
    我们只用motion Start,既可以启动这款软件,然后service motion start,即可以启动motion配备的apache服务器,然后就可以通过内网web进行控制。但是我这里想说的是实际上它并不安全,比如我们在外网通过ddns花生壳,以及内网渗透一些方式远程连接上去时候,任何人都可以无需任何密码访问等等。
    这时一个保护密码就必不可少了。
    我们通过vi编辑器进入etc下的motion默认目录,用vi打开其中的配置文件

# External Commands, Warnings and Logging:
# You can use conversion specifiers for the on_xxxx commands
# %Y = year, %m = month, %d = date,
# %H = hour, %M = minute, %S = second,
# %v = event, %q = frame number, %t = thread (camera) number,
# %D = changed pixels, %N = noise level,
# %i and %J = width and height of motion area,
# %K and %L = X and Y coordinates of motion center
# %C = value defined by text_event
# %f = filename with full path
# %n = number indicating filetype
# Both %f and %n are only defined for on_picture_save,
# on_movie_start and on_movie_end
# Quotation marks round string are allowed.

# Common Options for database features.
# Options require database options to be active also.
# motion的好处是可以连接数据库的,并且提供了sql的接口。
#####################################################################

# Log to the database when creating motion triggered picture file  (default: on)
; sql_log_picture on

# Log to the database when creating a snapshot image file (default: on)
; sql_log_snapshot on

# Log to the database when creating motion triggered movie file (default: off)

# Log to the database when creating timelapse movies file (default: off)
; sql_log_timelapse off

# SQL query string that is sent to the database
# Use same conversion specifiers has for text features
# Additional special conversion specifiers are
# %n = the number representing the file_type
# %f = filename with full path
# Default value:
# Create tables :
## 
# Mysql
# CREATE TABLE security (camera int, filename char(80) not null, frame int, file_type int, time_stamp timestamp(14), event_time_stamp timestamp(14));
#
# Postgresql
# CREATE TABLE security (camera int, filename char(80) not null, frame int, file_type int, time_stamp timestamp without time zone, event_time_stamp timestamp without time zone);

# insert into security(camera, filename, frame, file_type, time_stamp, text_event) values('%t', '%f', '%q', '%n', '%Y-%m-%d %T', '%C')

# Database Options
############################################################

# database type : mysql, postgresql, sqlite3 (default : not defined)
; database_type value

# database to log to (default: not defined)
; database_dbname value

# The host on which the database is located (default: localhost)
; database_host value

# User account name for database (default: not defined)
; database_user value

# User password for database (default: not defined)
; database_password value

# Port on which the database is located
#  mysql 3306 , postgresql 5432 (default: not defined)

# Database Options For SQLite3

# SQLite3 database (file path) (default: not defined)

# Video Loopback Device (vloopback project)
############################################################

# Output images to a video4linux loopback device
# The value '-' means next available (default: not defined)
; video_pipe value

# Output motion images to a video4linux loopback device
# The value '-' means next available (default: not defined)
; motion_video_pipe value


##############################################################
# 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/motion/thread1.conf
; thread /etc/motion/thread2.conf
; thread /etc/motion/thread3.conf
; thread /etc/motion/thread4.conf 

然后我们就能看到这样一个配置文件,我们如果要开启里面的某一项参数需要将;号去掉,所以我们只需要将stream_authentication前面的逗号去掉就行了,并且将stream_auth_method改成1,当然这实际上还不是安全的,因为并没有使用md5加密,密码都是通过明文进行处理,所以一旦有人拦截你网上的内网数据,那么就能gg

具体方法之后补充
