First, a brief description is given of an application scenario related to an embodiment of the present application.

At present, a monitoring system is widely applied to various video monitoring scenes. During video monitoring, when the camera equipment in the monitoring system monitors that an external event meets a preset video triggering condition, the video recording mode can be automatically started, and a recorded video file is stored in the storage equipment. In some scenarios, there may be a linkage relationship between multiple image capturing devices in the monitoring system, and in this case, there is also an association between the video files recorded by the multiple image capturing devices having the linkage relationship. When searching for a video file, if a certain video file is searched, it is generally desirable to be able to search for all other video files associated with the video file. In the related art, users can only manually search one by one from a large number of stored video files, which results in complex operation and low search efficiency.

Next, a brief description will be given of an implementation environment related to the embodiments of the present application.

Referring to fig. 1, fig. 1 is a schematic diagram illustrating an implementation environment including a storage device 110 and a plurality of image capture devices 120 according to an exemplary embodiment. Wherein the storage device 110 can establish a communication connection with each of the plurality of image pickup devices 120 through a network. Further, the implementation environment may further include a search device 130, and the storage device 110 may further establish a communication connection with the search device 130 through a network. In addition, some or all of the plurality of image pickup apparatuses 120 may establish communication connection with each other through a network.

The storage device 110 may be configured to store video files recorded by the plurality of camera devices 120. Further, the storage device 110 may also be used to store other information related to the video files or the image capturing devices transmitted by the plurality of image capturing devices 120, for example, the device identifier of the image capturing device may also be stored. In some embodiments, the storage device 110 may be a terminal such as a notebook computer, a desktop computer, a portable computer, and the like, which is not limited in this application.

The plurality of camera devices 120 may be configured to record video files and send the video files to the storage device 110 for storage. In some scenarios, a user may configure device information of other image capturing devices in a certain image capturing device 120 according to actual needs, and thus, when the certain image capturing device 120 performs a video recording operation, the configured other image capturing devices may be triggered to perform the video recording operation together, so as to obtain a plurality of associated video recording files. In some embodiments, each camera device 120 may be provided with a communication module, a processor, a memory, a camera, and the like, so that each camera device 120 may establish a communication connection with other camera devices 120 through the communication module, and in addition, may capture a video image through the camera to record a video file. The memory may be used for storing data or instructions, and the processor may be used for executing the instructions stored in the memory, so that each image capturing apparatus can execute the relevant operations of the method provided by the present application.

In addition, when the number of searched video files is plural, the plural video files may be played simultaneously in different display areas. In some embodiments, the search device 130 may be a terminal such as a tablet, laptop, desktop, laptop, or the like. The embodiment of the present application does not limit this.

It should be noted that the above-described implementation environment is only exemplary, in another embodiment, the storage device and the image capturing device in the implementation environment may also be integrated on one device, and in another embodiment, the storage device may also be provided with a search function, which is equivalent to that the storage device and the search device in the implementation environment are an integrated device, and this is not limited in this application.

After the application scenarios and the implementation environments related to the embodiments of the present application are introduced, the method for storing the video files provided by the embodiments of the present application will be described in detail with reference to the accompanying drawings.

Fig. 2 is a flowchart illustrating a method for storing a video file according to an exemplary embodiment, where the method for storing a video file is described in the embodiment of the present application by way of example as being applied to the implementation environment illustrated in fig. 1, the method for storing a video file may include the following steps:

step 201: when the image pickup equipment detects a video trigger event, generating video trigger indication information, wherein the video trigger indication information is used for indicating a master-slave trigger relationship between main trigger equipment and triggered equipment, the main trigger equipment is the image pickup equipment which triggers the triggered equipment to execute a recording operation after detecting that an external event meets a video trigger condition in the plurality of image pickup equipment, and the triggered equipment is any image pickup equipment in the plurality of image pickup equipment.

As described above, in an implementation environment, a plurality of image capturing devices may perform linked recording, and in implementation, the plurality of image capturing devices may be controlled to perform linked recording in a triggering manner. According to different triggering modes, the plurality of image pickup devices can be divided into a main triggering device and a triggered device, wherein the main triggering device can actively trigger other triggered devices to carry out linkage video recording under a certain condition, and the triggered device carries out linkage video recording after being triggered by the main triggering device.

Because the image capturing apparatus that detects the video recording trigger event may be the main trigger apparatus or the triggered apparatus, based on this, the situation that the image capturing apparatus detects the video recording trigger event is also different, which may specifically include:

in the first case: and when the external event is detected to meet the video recording triggering condition, determining that the video recording triggering event is detected.

The external event may refer to a user behavior, an animal behavior, a vehicle behavior, and the like in the monitored video picture. In addition, the video trigger condition may be preset according to actual requirements, for example, the video trigger condition may include, but is not limited to, a flame event being detected, a smoke event being detected, a human accident event being detected, and an article loss event being detected.

In this case, the image capturing apparatuses are main trigger apparatuses, that is, the image capturing apparatuses having a linkage relationship are not always in a linkage video recording state, but one or some of the main trigger apparatuses perform a monitoring operation, for example, in a video monitoring process, the main trigger apparatus may analyze a monitored video image, and when it is monitored that an external event satisfies a video recording trigger condition, start to perform a linkage recording operation to generate video recording trigger indication information, where the video recording trigger indication information may include a main apparatus identifier of the main trigger apparatus. And the main trigger equipment triggers other camera equipment which has linkage relation with the main trigger equipment to execute linkage video recording operation together.

In the second case: and when a video recording trigger signal sent by the main trigger equipment is received, determining that a video recording trigger event is detected.

In this case, the image pickup apparatus is a triggered apparatus, wherein the video recording trigger signal is sent by the main trigger apparatus and used to instruct the triggered apparatus to perform a linked video recording operation, and at this time, the triggered apparatus performs the linked video recording operation to generate video recording trigger instruction information.

For the triggered device, after receiving the video trigger signal sent by the main trigger device, the video trigger indication information may be generated to indicate the main-slave trigger relationship between the main trigger device and the triggered device by using the video trigger indication information, in other words, it may be determined who triggered to execute the recording operation according to the video trigger indication information.

As an example, the recording trigger signal may carry a master device identifier of a master trigger device. In this case, the specific implementation of the triggered device generating the video recording trigger indication information may include: and generating the video recording trigger indication information based on the main equipment identifier and the slave equipment identifier, wherein the slave equipment identifier is the equipment identifier of any one image pickup equipment.

The device identifier may be used to uniquely identify one image capturing device. That is, the triggered device may record the master-slave triggering relationship between the master triggering device and the triggered device through the corresponding relationship between the master device identifier and the slave device identifier.

Further, the triggered equipment executes the video recording operation. When the triggered device is also configured with device information of other image capturing devices, the triggered device may send a trigger signal to the other image capturing devices to trigger the other image capturing devices to perform a video recording operation, where for the other triggered image capturing devices, the triggered device is relatively a main trigger device. That is, the master triggering device and the triggered device described in this application are relative concepts.

Step 202: the camera device sends video data to the storage device, the video data includes the video trigger indication information, and the video trigger indication information is used for the storage device to establish a master-slave trigger relationship between the master trigger device and the triggered device.

The video data may further include a video file recorded by the camera device, that is, the camera device may carry the recorded video file through the video data.

As described above, the image pickup apparatus may be a main image pickup apparatus or a triggered image pickup apparatus, wherein the main trigger apparatus transmits the video recording file recorded by itself to the storage apparatus, and also transmits the video recording trigger indication information to the storage apparatus, so as to inform the storage apparatus that the current video recording file is from the linked video recording. Similarly, for the triggered device, besides sending the video file recorded by the triggered device to the storage device, the video triggering indication information is also sent to the storage device, and at the moment, the video triggering indication information comprises a main device identifier and a slave device identifier, so that the storage device can know who triggers the linkage video recording of the triggered device.

As an example, the recording data may further include other information, such as at least one of a start recording time, an end recording time, and an external event type of the recording file.

It should be noted that, because the image pickup device sends the video data to the storage device, the video data includes the video trigger indication information, so that the storage device can determine the master-slave trigger relationship between the master trigger device and the triggered device based on the video trigger indication information, and thus obtain the video files recorded by the plurality of linked image pickup devices according to the master-slave trigger relationship.

As an example, the storage device may store the content in the video data as follows.

Step 203: the storage device receives video data, which is recorded by a plurality of image pickup devices.

In a possible implementation manner, the storage device may store the video files recorded by each image capturing device with the device identifier of each image capturing device as an index. Further, when the image capturing device further uses at least one of the recording start time, the recording end time, and the external event type, the storage device may further use at least one of the recording start time, the recording end time, and the external event type and the device identifier together as an index to store the video file recorded by each image capturing device.

Step 204: when the video data comprises video triggering indication information, the storage device records a master-slave triggering relationship between the master triggering device and the triggered device based on the video triggering indication information.

As described above, the main triggering device is an image capturing device that triggers the triggered device to perform a recording operation when detecting that an external event satisfies a recording triggering condition, and the triggered device is any one of the image capturing devices.

When the video data includes video triggering indication information, it is indicated that a plurality of camera devices are linked for video recording, and in order to facilitate the follow-up search of all video files with association relations at one time, the storage device records the master-slave triggering relation between the master triggering device and the triggered device indicated by the video triggering indication information.

In a possible implementation manner, when the video recording trigger indication information includes a master device identifier of the master trigger device and a slave device identifier of the triggered device, a specific implementation of recording a master-slave trigger relationship between the master trigger device and the triggered device that are indicated by the video recording trigger indication information may include: and correspondingly recording the master equipment identifier and the slave equipment identifier into a master-slave triggering relation table, wherein the master-slave triggering relation table is used for recording the master-slave triggering relation between the camera equipment with the association relation.

In some embodiments, the master-slave triggering relationship table may include a master device identification item and a slave device identification item, so as to correspondingly record a master-slave triggering relationship between the image capturing devices having an association relationship through the master device identification item and the slave device identification item. In this way, the storage device may add the master device identifier in the video trigger indication information to the master device identifier item, and add the slave device identifier in the video trigger indication information to the slave device identifier item.

For example, if the master device identifier a and the slave device identifier B of the triggered device in a certain video trigger indication information are assumed to be a, the master device identifier a and the slave device identifier B are correspondingly recorded in the master-slave trigger relationship table, and the obtained master-slave trigger relationship table may be as shown in table 1:

TABLE 1

Of course, if the number of the video data is multiple, the storage device may record the master-slave triggering relationship between the master triggering device and the triggered device indicated by each video triggering indication information based on the video triggering indication information in each video data, and the recording result is as shown in table 1 above.

Further, the recording data further includes at least one of a recording start time, a recording end time, and an external event type, and at this time, the storage device records at least one of the recording start time, the recording end time, the external event type, the master device identifier, and the slave device identifier in the master-slave trigger relationship table in a corresponding manner.

For example, assuming that the recording trigger indication information in a certain recording data includes a master device identifier a, a slave device identifier B of a triggered device, and the recording start time, the recording end time, and the external event type in the recording data are 10:00, 11:30, respectively, and MOTION, the storage device records the recording start time, the recording end time, the external event type, the master device identifier a, and the slave device identifier B into the master-slave trigger relationship table, and the obtained master-slave trigger relationship table may be as shown in table 2:

TABLE 2

Master device identification	Slave device identification	Type of triggering event	Recording start time	End time of recording
					A	B	MOTION	10:00	11:30
A	F	MOTION	10:00	11:30
					A	G	MOTION	10:00	11:30
F	G	MOTION	10:00	11:30
					F	D	MOTION	10:00	11:30
...	...	...	...	...

Similarly, if the number of the video data is multiple, the storage device may correspondingly record at least one of the recording start time, the recording end time, the external event type, the master device identifier, and the slave device identifier in each video data into the master-slave triggering relationship table, where the recording result is as shown in table 2 above.

Because the storage device stores the master-slave relationship among the camera devices of the plurality of linkage videos and also records the corresponding relationship between the information such as the device identification of each camera device and the video files, when a user needs to search out a plurality of video files with the linkage relationship, the storage device can search out all the video files at one time based on the information such as the device identification of any camera device in the plurality of camera devices of the linkage videos, and thus, the searching effect of the video files is improved.

In the embodiment of the application, the storage device receives video data recorded by a plurality of image pickup devices, and if the video data includes video trigger indication information, the storage device records a master-slave trigger relationship between the master trigger device and the triggered device according to the video trigger indication information, that is, records which image pickup device triggers which image pickup device to execute a video recording operation. The main trigger device is an image pickup device which triggers a triggered device to execute recording operation after detecting that an external event meets a video recording trigger condition in the image pickup devices, and the triggered device is any one of the image pickup devices. Because the storage device records the association relationship between the camera devices with the master-slave triggering relationship, all associated video files can be searched out at one time according to the master-slave triggering relationship when a search request is received, so that a user can simultaneously check videos recorded from a plurality of angles.

Fig. 3 is a flowchart illustrating a method for searching for a video file according to an exemplary embodiment, where the method for searching for a video file is described in the embodiment of fig. 1, and the method for searching for a video file may include the following steps:

step 301: the storage device receives a search request.

As an example, the storage device stores a video file obtained by linking video recording of a plurality of image capturing devices, and further records a master-slave triggering relationship between the plurality of image capturing devices, and a specific implementation thereof may be seen in the embodiment shown in fig. 2.

Illustratively, the storage device records the master-slave triggering relationship among the plurality of image pickup devices in a master-slave triggering relationship table. Further, the master-slave trigger relationship table records at least one of a recording start time, a recording end time and an external event type, and the at least one of the recording start time, the recording end time and the external event type is correspondingly stored with the device identifier.

As an example, the search request may be sent by a search device, and when a user wants to search for a certain recording file or certain recording files in the stored recording files, the search request may be sent to the storage device through the search device, and the search request may carry a device identifier of a certain image capturing device. Wherein, the device identifier may be a master device identifier, and the master device identifier is used to identify a master trigger device, and then the following step 302 is executed; or it may be a slave device identity, which is used to identify a triggered device, when the following step 303 is performed.

Step 302: when the search request includes the master device identifier of the master trigger device, the storage device determines the device identifiers of all the image pickup devices triggered by the master trigger device according to a master-slave trigger relationship table, wherein the master-slave trigger relationship table is used for recording master-slave trigger relationships among the image pickup devices with the association relationships.

That is, when the device identifier carried in the search request by the search device is the master device identifier, the storage device determines, according to the stored master-slave trigger relationship table, the device identifiers of all the image capturing devices triggered by the master trigger device, for example, referring to table 2 in the embodiment of fig. 2, assuming that the device identifier carried in the search request is a, the device identifiers of all the image capturing devices triggered by the corresponding master trigger device may be searched, including: B. f, G are provided. Further, since the searched triggered device B also triggers another image pickup device D, the image pickup device D can be indirectly considered to be also a triggered device, and thus the final query result can also include the device identification D.

Step 303: when the search request comprises the slave equipment identification, the storage equipment determines the master equipment identification corresponding to the slave equipment identification according to the master-slave triggering relation table, and determines the equipment identifications of all the image pickup equipment triggered by the master triggering equipment corresponding to the master equipment identification.

When the device identifier carried in the search request is the slave device identifier, the storage device determines, according to the master-slave triggering relationship, a master triggering device that triggers the triggered device corresponding to the slave device identifier, and then determines device identifiers of all the image pickup devices that trigger the master triggering device.
