Terminal collection station:

basic skills:

1. Automatically correct the time of the law enforcement instrument:

When the law enforcement recorder is connected to the data collection device, the time of the collection station is automatically used to correct the time of the law enforcement instrument, and the time tags of the documents are batch corrected.

2. Automatically synchronize the detachment server time:

After all collection stations are connected to the detachment server, the time of the collection station is automatically corrected by the collection system, and the time of all collection stations and the time of the detachment server are synchronized.

3. Large file transfer function:

It can stably and quickly transfer large files up to 4G.

4. Breakpoint resume function:

The law enforcement instrument can be directly pulled out and used during data transmission with the collection station. After use, the law enforcement recorder can continue to transmit the files that have not been transmitted last time when it is connected to the same collection station.

5. Mass storage read and write:

Using optimized algorithms, it realizes fast reading and writing of large-capacity storage space, provides access to large-capacity disk space speed, and realizes the simultaneous data collection speed of five law enforcement instruments simultaneously higher than 4.0Gbps / minute.

6. Real-time monitoring technology of the collection station:

The status information of the collection station is transmitted to the server background in real time, and the storage space of the collection station, whether it is online, and the number of files can be monitored in real time through the management background.

7. Efficient disk space:

After customizing the space management strategy, the system automatically manages the disk space without manual intervention and can periodically clear out expired media files according to the customized strategy. When multiple law enforcement instruments transmit data concurrently, they can automatically find free disk storage data. If there are multiple hard disks in a collection station, after a disk is full, it can automatically convert the drive letter storage according to the order.

8. Intelligent upload strategy management:

It supports real-time and regular uploading of video files to a file server. Users can formulate upload strategies so that the system only uploads important video files.
