1. Introduction 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.
With a rich set of wireless and wired interfaces – Wi-Fi hotspot, BT tethering and BLE, Bluetooth audio, NFC, Wi-Fi Direct, multiple CAN channels (including open/customizable CAN libraries), and multiple I/Os – the Micronet SmartCAM™ can function as an in-cabin hub to easily connect with other devices, sensors, and accessories. Driver notification features such as system status LEDs, warning indicators, internal speakers, and microphone are also provided for device control and driver alerting purposes.
Compatibility with Micronet SmartX Products The Micronet SmartCAM™ is based on the same hardware and software platform as the Micronet SmartHub, SmarTab, and Tab 8 – Micronet’s next-generation Android On-Board-Computer. Telematics Service Providers who develop applications for Micronet’s SmartX series products can easily adjust and run those apps on the Micronet SmartCAM™ for customers who also need that as part of their solution.
and remote training, which significantly reduces operational costs over the lifetime of the product and substantially improves user experience and customer satisfaction. GSD® features white-label cloud-based SaaS solutions offered as two key services: 1. Mobile Device Management and remote control. 2. Fail-safe firmware and application over-the-air updates (FOTA/OTA).

These are listed below: Access Point Configuration: NOTE: No cellular connections are vailable 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.
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 PROGRESS – The PCB will require a resistor of lesser value to provide the best possible gain.
