And the router of ADSL routing functions.
Camera device, stop shooting instruction for receiving, close camera function；Receive and start shooting instruction, start shooting
Function；
In the embodiment of the present invention, camera device carries out respective handling according to the instruction of reception, that is, receives and stop shooting instruction
Afterwards, current camera function is terminated, camera device is placed in holding state；Receive after starting shooting instruction, restarting shooting
Function is imaged.
Router, for monitoring the mobile communication equipment belonged in the wireless network, if monitoring that mobile communication is set
It is standby, obtain the positional information of the mobile communication equipment, according to the positional information calculation obtained and the mobile communication equipment away from
From：
If the distance calculated is less than the last distance calculated, and less than the first distance threshold pre-set, and really
Determine camera device and be currently at shooting state, exported to the camera device and stop shooting instruction；If the distance calculated is more than
The distance that last time calculates, and more than the second distance threshold value pre-set, and determine that camera device is currently at non-shooting shape
State, exported to the camera device and start shooting instruction.
In the embodiment of the present invention, if mobile communication equipment is once into the WiFi signal covering model of oneself wireless router
In enclosing, it is possible to camera device is closed in triggering, and when mobile communication equipment once leaves the WiFi signal of oneself wireless router
Coverage, then the camera function for needing triggering to start in camera device is imaged, to be taken the photograph in real time to scene in household
Picture, ensure house security.So, after user enters the WiFi signal coverage of wireless router, but user is also introduced into
The image pickup scope of camera device, the camera function of camera device is closed, so as to effectively prevent the leakage of user privacy information, carried
The security of user privacy information is risen；Further, when user leaves home, when user is gradually distance from the WiFi of wireless router
Signal cover, and user is located at outside the image pickup scope of camera device, then the camera function for starting camera device is triggered, both
Shooting of the camera device to user, security monitoring of the and can effective guarantee to household can be avoided.
Certainly, in practical application, according to positional information calculation and the mobile communication equipment obtained distance and enter
The judgement of row distance information, it can also be arranged in camera device and carry out.
In the embodiment of the present invention, the first distance threshold can be configured with second distance threshold value according to being actually needed, example
Such as, can according to user be actually needed and the WiFi signal coverage of combining wireless router determines first apart from threshold
Value, as long as the first distance threshold of setting is less than the WiFi signal coverage of wireless router.Certainly, practical application
In, as another alternative embodiment, the first distance threshold of setting can also be more than the WiFi signal covering model of wireless router
Enclose.For example, the first distance threshold could be arranged to 200m, 500m, 1000m etc., i.e., in the router, according to setting not
With the first distance threshold, following automatic closing camera device option can be set：

In the embodiment of the present invention, second distance threshold value can be identical with the first distance threshold, can also be with first apart from threshold
Value is different.
As alternative embodiment, if the distance calculated is less than the first distance threshold pre-set, and shooting dress is determined
Put and be currently at non-shooting state, do not deal with；If the distance calculated is more than the second distance threshold value pre-set, and determines
Camera device is currently at shooting state, does not deal with.
As alternative embodiment, router can timing or the request of not timing broadcasting equipment position enquiring, in the router
WiFi signal coverage in, if the mobile communication equipment in wireless network receive broadcast device location inquiry please
Ask, the positional information of itself is carried in the response of device location inquiry request, is back to router, router receiving device position
Inquiry request response is put, it is determined that the mobile communication equipment for sending the response of device location inquiry request is the movement in wireless network
After communication equipment, i.e., mobile communication equipment is authenticated, after authentication passes through, perform the position for obtaining the mobile communication equipment
The flow of information.
In the embodiment of the present invention, as alternative embodiment, mobile communication equipment is by scanning WiFi network and obtaining WiFi
Access point identity information, determined whether for wireless network network, to be defined as wireless network according to the WiFi access point identity information of acquisition
After network network, wireless network network is accessed by access pin, receives the device location inquiry request of wireless network network broadcast, and will be certainly
The positional information of body is carried in the response of device location inquiry request, is back to router.
In the embodiment of the present invention, WiFi network can broadcast WiFi signal, and mobile communication equipment is sent out by searching for WiFi network
The WiFi signal gone out, is thus connected to WiFi network.Specifically, when mobile communication equipment enters the 802.11b/ for the standard that is laid with
During g network environments, the WiFi signal receiver built in mobile communication equipment can be utilized, passes through 802.11 protocol suite Plays
Protocol interface sends the WiFi network in link information scanning current environment, is determined currently according to the connection response information of return
After environment has WiFi network, the WiFi network identification information of the existing WiFi network is obtained.For example, can be by mobile communication
Equipment judges that mobile communication equipment is to access internet by mobile communication base station or lead to according to the connection response information of return
WiFi access points access internet is crossed, and when it is determined that mobile communication equipment accesses internet by WiFi access points, obtains and moves
The WiFi access point identity information of dynamic communication equipment connection.Wherein, WiFi access point identities information can be WiFi access points (road
By device) service set identifier (SSID, Service Set Identifier) information or WiFi access points IP address letter
