SFWR0036 : FleetMind Cellular Data Usage – Do’s & Dont’s

Description:

This document is intended to provide knowledge on how FleetMind services consume Mobile Data, which applications trigger the data usage, and how can we prevent overusing your data plan. We will also talk in detail about Camera recording data calculations & VNC (Virtual Network Computing) data calculations.

What Triggers Data Usage?

StreetSmart – Streaming Video/ Archive Videos/ Events/ Uploading Video/ Downloading Video from the server.
FRM Reports – BreadCrumbs/ Bin Monitor/ Alarms/ Exceptions/ Incidents/ Accidents etc.
OBC Updates – Updating WasteApp Versions
VNC – Updating Configurations (Note: VNC is only for FM Customer Support Use)

How can we prevent overusing your data plan?

Not using VNC for Streaming Realtime Videos, VNC needs to be used by the FM Support/Deployment team only.
When downloading the video, don’t save all the cameras, use the specific Camera angle as per your requirement
Check your camera settings

Camera Recording Data Calculations:

Resolution D1 with 12 frames per second.
1 cam * 1 min = ~13.5 MB
1 cam * 1min * 60 = ~ 825 MB
1 cam * 10 hours = 8250 MB
1 cam * 90 days = ~7.30 GB

Sampling from the City of XXX/Vehicle YYY

Example 1: The vehicle was moving ~50% of the time.
- 4 cameras recording + 4 black. – 1 minute – 55 MB (1 camera = 13.75 MB)
Example 2: The vehicle is on a halt. Cameras were recording blinking lights.
- 6 cameras recording – 1 minute – 66 Mb (1)

Local Tests

Average storage consumption for 1 x Camera (non HD) per 1 minute

CAMERA	RESOLUTION	30 FPS	24 FPS	15 FPS	12 FPS
1	D1	14.2 MB	13.9 MB	13.4 MB	12.4 MB
1	CIF	9.7 MB	8 MB	5.5 MB	4.1 MB
1	QCIF	4.5 MB	3.1 MB	2.0 MB	1.8 MB

1 camera, 1 day, 10 hours per day ( x * 60 min * 10 hours * 30 days )

CAMERA	RESOLUTION	30 FPS	24 FPS	15 FPS	12 FPS
1	D1	8520 MB	8340 MB	8040 MB	7440 MB
1	CIF	5820 MB	4800 MB	3300 MB	2460 MB
1	QCIF	2700 MB	1860 MB	1200 MB	1080 MB

1 camera, 30 days, 10 hours per day ( x * 60 min * 10 hours * 30 days)

CAMERA	RESOLUTION	30 FPS	24 FPS	15 FPS	12 FPS
1	D1	255600 MB	250200 MB	241200 MB	223200 MB
1	CIF	174600 MB	144000 MB	99000 MB	73800 MB
1	QCIF	81000 MB	55800 MB	36000 MB	32400 MB

Camera Recording Streaming Settings:

Cif with Frame Rate 5 which is low but acceptable

For Upload:

D1 with FrameRate 12

About 12.4 per 1 min for 1 cam
5 Cams will be 124 Mb compressed around 40 to 80 Mb
8 Cams will be 198.4 Mb which around 80 to 100 Mb

VNC (Virtual Network Computing) data calculations:

Virtual Network Computing (VNC) is a graphical desktop sharing system that uses the Remote Frame Buffer protocol (RFB) to remotely control another computer.

Below is the comparison between different types of VNC under Lower Bandwidth: In terms of network utilization, during a fairly low-activity, non-use period of time when I leave the connected screen untouched for about 5 minutes.

VNC is majorly used by the Fleetmind Customer Support and Deployment Team.

We don't encourage consumers/clients to use VNC.

We use 8bits with 256 colors to lower the data Consumption.
