Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
It should be noted that although functional block divisions are provided in the system drawings and logical orders are shown in the flowcharts, in some cases, the steps shown and described may be performed in different orders than the block divisions in the systems or in the flowcharts. The terms first, second and the like in the description and in the claims, and the drawings described above, are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order.
In a first aspect, referring to fig. 1, fig. 1 is a flow chart of steps of a method for accessing a video file of an office camera.
The method for accessing the video file of the office camera comprises the following steps:
step 1, dividing a video file obtained by an office camera into a first image file and a second image file, storing the first image file in a first memory, and storing the second image file in a second memory, wherein the average sampling time of the first image file is later than that of the second image file;
step 2, obtaining an access request of an accessor, and requesting the accessor to provide a first check code;
step 3, checking the validity of the first check code;
step 4, when the first check code is legal, establishing an independent communication channel which is in contact with the visitor based on the first check code, and requesting the visitor to provide access permission through the independent communication channel;
and 5, obtaining the access authority provided by the visitor, and sending the access address of the first memory or the access address of the second memory to the visitor according to the access authority, wherein the access authority of the first image file is higher than that of the second image file.
The method for accessing the video file of the office camera aims to reasonably limit the access of the video file obtained by the office camera so as to avoid the video file from leaking.
Therefore, the video file access method of the office camera divides the video file obtained by the office camera into a first image file and a second image file. The image reflected by the first image file is closer to the current situation than the image reflected by the second image file. The concrete expression is as follows: the average sampling time of the first image file is later than that of the second image file. The average sampling time of the first image file refers to the average time of the office camera when the content reflected by the first image file is sampled. The average sampling time of the second image file refers to the average time of the office camera when the content reflected by the second image file is sampled. The average sampling time of the first video file is later than the average sampling time of the second video file, which indicates that the average sampling time of the first video file is closer to the current time and the average sampling time of the second video file is farther from the current time. The purpose of step 1 is to separate the first image file and the second image file by the first image file and the second image file, and store the first image file and the second image file in the first memory and the second memory respectively.
After the first image file and the second image file are separately stored, an access request of the visitor can be responded. Specifically, the access request of the visitor may be obtained, for example, a request instruction indicating that access is required is obtained, where the request instruction is sent by the visitor. After obtaining the access request, in order to check the validity of the identity of the visitor, the visitor is requested to provide a first verification code.
When the visitor provides the first verification code, a validity check may be performed on the first verification code to verify the identity of the visitor. Access by an illegal visitor is avoided. In some preferred embodiments, the checking the validity of the first verification code specifically includes: and acquiring a first check code, wherein the first check code is encrypted in advance by an encryption server, the first check code is sent to a decryption server for decryption to obtain a second check code, the second check code is locally matched, and when the matching is successful, the first check code is considered to be legal.
The first check code can be used for early screening of the visitor, so that access of illegal visitors is avoided.
When the first check code is legal, an independent communication channel which is in contact with the visitor can be established based on the first check code, and after the independent communication channel is established, the visitor can be requested to provide access permission based on the independent communication channel. The access right is preset and refers to a right for accessing the first image file and the second image file.
Through establishing independent communication channel, can guarantee that the visitor carries out data transmission in independent communication channel, can promote data transmission's rate, guarantee communication channel's independence, can avoid the interference of other factors.
After the access authority of the visitor is obtained, whether the visitor can access the first image file or the second image file can be known according to the access authority, wherein the access authority of the first image file is higher than the access authority of the second image file. After the access authority of the visitor is determined, the access address of the first memory or the access address of the second memory may be sent to the visitor, so that the visitor can access the first image file or the second image file conveniently, and the video file desired by the visitor is obtained.
The visitors can be further classified by setting the access authority, so that the access of the visitors is limited, and the security of the office camera video file is protected to the greatest extent.
According to the method for accessing the video file of the office camera, multiple restrictions are performed on an accessor, so that the security of the video file obtained by the office camera is protected to the greatest extent, and illegal access is avoided.
In some preferred embodiments, in step 1, dividing the video file obtained by the office camera into a first image file and a second image file, storing the first image file in the first memory, and storing the second image file in the second memory specifically includes: the method comprises the steps of setting a buffer, wherein the buffer is used for storing video streams transmitted by an office camera in real time, when the video streams stored by the buffer exceed a set capacity, the video streams stored by the buffer form video files, the video files are cut into a first storage as first image files, the first storage is used for storing the first image files with the set capacity, when the capacity of the first storage is full, all the video files stored by the first storage are cut into a second storage, and the storage capacity of the second storage is larger than that of the first storage. By the distribution mode, the video file can be well divided into the first image file and the second image file, and the first image file and the second image file are correspondingly stored.
In some preferred embodiments, in step 4, establishing an independent communication channel with the visitor specifically includes: and allocating a communication channel, taking the first check code as an authentication identifier for entering the communication channel, and only allowing a visitor holding the first check code to enter the communication channel. The first check code is used as the authentication identification of the access communication channel, so that the visitor can conveniently access the communication channel, and other illegal persons can be prevented from intruding the communication channel, thereby realizing the independence of the communication channel.
