A: The data usage generated during monitoring is calculated based on live stream, while the data usage generated by files
uploaded to the FTP server is calculated based on storage stream.

Power Consumption
The device's power consumption varies depending on the following three conditions:
Sleep mode: 96 mA
Eight cameras and a display: 2–4 A
A single camera: 100–400 mA (The light in the daytime is strong, so the power consumption is low. The light in the night is weak,
so the power consumption is high.)
1)
Q: If the engine is not started, will the vehicle battery be quickly consumed by the device?
A: If the engine is not started, the recording function of the device is disabled. So the power consumption will be lower than
100 mA and excessive consumption of the vehicle battery will not happen.
2)
Q: How to reduce the power consumption?
A: You can reduce the number of peripherals, alert event uploading times and camera channels.

Video Storage
The maximum storage capacity of the MDVR varies depending on the capacity of hard disks on the market. The MDVR supports
a hard disk with a capacity of 256 GB, 512 GB, 1 TB, or 2 TB. So users can choose a proper hard disk as needed. For details about
the storage time of the device with different capacity, see the following tables. As shown in the following tables, the storage time
of the storage disk with the largest capacity ranges from three days to 320 days due to the image quality and the number of
channels.
