9.2 Data Usage Consumption
Data usage depends on the size of data uploaded from the device. Uploaded data contains video data and positioning data.
Video data calculation formula: Bitrate (Kbs)/8 x Number of channels /1024 = Data usage consumption per second (MB)
(Note: The formula is applicable to scenarios that the device is monitored continuously via the platform or uploads video files
continuously. It will become unavailable when functions of monitoring and FTP uploading are enabled at the same time or
operators have special data usage calculation methods.)
Positioning data calculation formula: 0.2KB x 3600/GPRS interval x 24/1024 = Data usage consumption per hour (MB)
(Note: The formula is applicable to general use scenarios. It will become unavailable when commands are frequently sent to
read and write, photos are frequently uploaded, or operators have special data usage calculation methods.)
Under normal circumstances, data usage of the device is as follows:
