In a first aspect, referring to fig. 1, fig. 1 is a flow chart of steps of a method for accessing an office camera video file.
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 a visitor, and requesting the visitor 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 for contacting the visitor based on the first check code, and requesting the visitor to provide access rights through the independent communication channel;
and 5, obtaining access rights 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 rights, wherein the access rights of the first image file are higher than those of the second image file.
The office camera video file access method aims at reasonably limiting the access of the video file obtained by the office camera so as to avoid the video file from leaking.
For this purpose, 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 steps are as follows: the average sampling time of the first image file is later than the average sampling time of the second image file. The average sampling time of the first image file refers to the average time of the office camera when sampling the content reflected by the first image file. The average sampling time of the second image file refers to the average time of the office camera when sampling the content reflected by the second image file. The average sampling time of the first image file is later than the average sampling time of the second image file, which means that the average sampling time of the first image file is relatively close to the current time, and the average sampling time of the second image file is relatively long from the current time. The purpose of step 1 is to divide and store the first image file and the second image file in the first memory and the second memory respectively by dividing the first image file and the second image file.
After the first image file and the second image file are stored separately, an access request of a visitor can be responded. The access request of the visitor can be obtained, for example, a request instruction which is sent by the visitor and indicates that the visitor needs to access is obtained. After the access request is obtained, in order to verify the identity legitimacy of the visitor, the visitor is required to be requested to provide a first check code.
When the visitor provides the first check code, a validity check may be performed on the first check code to check the identity of the visitor. Avoiding illegal visitors from accessing. In some preferred embodiments, checking the validity of the first check 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, a second check code is obtained, the second check code is locally matched, and when the matching is successful, the first check code is considered legal.
The first check code can be used for carrying out early screening on the visitor, so that illegal visitors are prevented from accessing.
When the first check code is legal, an independent communication channel for contacting 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 rights based on the independent communication channel. The access authority is preset and refers to the authority capable of accessing the first image file and the second image file.
By establishing the independent communication channel, the visitor can be ensured to carry out data transmission in the independent communication channel, the data transmission rate can be improved, the independence of the communication channel is ensured, and the interference of other factors can be avoided.
After the access right 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 right, wherein the access right of the first image file is higher than that of the second image file. After determining the access authority of the visitor, the access address of the first memory or the access address of the second memory can be sent to the visitor so that the visitor can access the first image file or the second image file, and therefore the video file wanted by the visitor is obtained.
The access rights are set to further classify the visitors and limit the visitors to access, so that the security of the video files of the office camera is protected to the greatest extent.
The access method of the video file of the office camera furthest protects the security of the video file obtained by the office camera and avoids illegal access by carrying out multiple restrictions on visitors.
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 that a buffer is arranged, the buffer is used for storing video streams transmitted by an office camera in real time, when the video streams stored in the buffer exceed a set capacity, the video streams stored in the buffer are formed into video files, the video files are cut into a first memory as first image files, the first memory is used for storing the first image files with the set capacity, when the first memory is full, all the video files stored in the first memory are cut into a second memory, and the storage capacity of the second memory is larger than that of the first memory. 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 a separate 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 allowing only a visitor with the first check code to enter the communication channel. The first check code is used as an authentication identifier for entering the communication channel, so that a visitor can conveniently enter the communication channel, and other illegal persons are prevented from intruding, and the independence of the communication channel is realized.
