Micronet SmartCAM Platform Overview

In today’s commercial Telematics industry there is a growing demand for onboard devices that not only send sensor data from the vehicle and driver environment for backend processing, but devices that also analyze, detect and notify the driver in real-time of any potential safety risks, operational errors, and protocol violations. Events such as near-collision, tailgating, unsafe lane departures, hard braking/cornering/accelerating, stop sign violations, speeding, distracted driving, driver fatigue, and more comprise a rich dataset that is used by fleet managers to measure their drivers’ skills and performance. It is also used to deploy training and education programs that result in improved fleet
safety, reduced insurance claims and premiums, higher up-time, and lower maintenance costs. The Micronet SmartCAM™ enables fleet managers to address all these safety events not only through conventional Telematic sensors such as GPS, 3D accelerometer, I/O, and CANbus but also by providing the ‘Full Picture’ through a rich set of real-time, onboard video analytics and AI capabilities enabled by a dual automotive-grade camera for road and in-cabin monitoring all packaged into a single device.

SmartCAM™ Installation

Mechanical Installation
Mounting Sunshield

The mountable sunshield of the Micronet SmartCAM™ should be attached to the vehicle’s windshield using the adhesive provided in the DTK for installation. The fast and easy-to-use permanent bonding adhesive method provides high strength and long-term durability. It is virtually invisible and keeps surfaces smooth. It can replace mechanical fasteners (rivets, welds, screws) or liquid adhesives, and eliminate drilling, grinding, refinishing, screwing, welding, and associated clean-up. It also creates a permanent seal against water, moisture and more.

NOTE:
In-vehicle installation instructions must be provided by a qualified installation technician.

Mounting Location and Dimensions
The sun shield can rotate every 8 degrees for click-turn positioning with two adhesive pads. Place the adhesive pads on the mounting sun shield as shown in the figure below:

Windshield Spacing
To mount the sunshield after applying the adhesive pads, press the sunshield firmly on to the vehicle windshield about four inches above the wiper blade path slightly off-center to the right like below:

Device Installation Steps

1. Determine the optimal positioning of the Micronet SmartCAM™ in the vehicle that provides easy access and a clear view of both the road and the display.
2. Attach the two adhesive pads to the mounting sunshield of the Micronet SmartCAM™ (make sure the sunshield is free of dust and debris.
3. Press and hold the mounting sunshield with adhesive pads on the pre-determined windshield position for at least 30 seconds.

Follow the cable installation steps as described in Electrical Installation.

Electrical Installation

Known Issues

Overview
The Micronet SmarTab 8 has some known issues discovered in the alpha launch and pre-production testing. These are listed below:
Access Point Configuration:
NOTE: No cellular connections are available in the SmartCAM Basic model which requires the device to connect via Wi-Fi. Active WiFi-Direct connections should NOT be available in specific cases i.e. no application may use the device in WiFi-Direct or Hotspot mode when an update is scheduled to allow the device connecting client AP in station mode.

BUG – Cellular Access Points (APs) are not pre-defined through configuration files; neither are the APs automatically generated upon booting the Micronet SmartCAM with microSIM cards.

WORKAROUND (temporary) – Customers should predefine AP data in the Micronet SmartCAM Wi-Fi settings for internet connectivity.

SD Card Format Error:
BUG – When an SD Card is inserted to the SmartCAM, the Android OS attempts to format it as “Internal” (application) storage, which fails and displays “Not Supported” (This is a specific version limitation).

WORKAROUND (temporary) – To use the “External” (data storage) of the SD card, we recommend formatting it externally on a PC as a FAT32 file system prior to inserting the SD card it into the Micronet SmartCAM device. Doing this will ensure the correct behavior of the SD card as external storage.

Battery Depletion Reboot:

BUG – When the battery is depleted below a 5% threshold the Micronet SmartCAM will start booting in a reboot loop after charging for some moments.
FIX IN PROGRESS – Should be fixed by using the correct battery profile in firmware.

Battery Not Charging:
BUG – The Micronet SmartCAM’s battery won’t fully charge and it depletes too fast due to the absence of a customized battery profile.

FIX IN PROGRESS – Should be fixed by using the correct battery profile in firmware.

Roadside Camera Performace:
BUG – The Micronet SmartCAM’s roadside camera performance is degraded due to an uncalibrated camera sensor. FIX IN PROGRESS – Will be fixed by applying correct camera calibrations.

Microphone Gain:
BUG – The Micronet SmartCAM’s external microphone doesn’t provide sufficient gain.
FIX IN PROGRES S – The PCB will require a resistor of lesser value to provide the best possible gain.

IR LED Brightness:
BUG – The Micronet SmartCAM’s Infrared LED brightness of the driver-side camera needs to be finetuned for optimal performance.
FIX IN PROGRESS – Currently undergoing testing.
