2. Installation

Ensure the car is parked and follow the instructions to install the product for the best shooting angle and quality.

Mount

Buckle the device with the base holder bracket. Find a suitable installation position, clean the glass, and peel off the cover of the red sticker on the base holder bracket. Stick the base holder bracket to the glass slowly and firmly.

Note: The sticker may lose its stickiness due to long-term sunlight exposure or other human factors.

Diagram Description: Illustrations show the process of attaching the bracket: buckling the device to the bracket, sticking the bracket to the windshield, and adjusting the angles.

Adjust the Lens

Adjust the lens position to achieve a perfect viewing coverage after installation.

Power On & Start Recording

Insert the Micro SD card into the card slot of the device. Connect the power cable (the side connecting to the cigarette lighter plug) to the mini USB port of the device. The device will power on and start recording automatically after the car engine starts. When the car is powered off, it automatically stops recording and saves the recorded file.

Note: Please use an SD card with Class 10 level or above, with a capacity no less than 8GB. The product supports up to 256GB.

Cable Connection

Install and tuck away the cable properly to avoid obstructing the driver's viewing. In most vehicles, cables can be tucked into the headliner. Professional installation is recommended. Please refer to Chapter 6 for more cable information.

3. Basic Operation

Video recording starts automatically and continuously after the D310F device powers on and completes initialization. It can then receive input instructions from an external device (usually a Vehicle Tracker) via the RS232 port. The main cable features an RS232 connection port for connecting to a Vehicle Tracker.

Typical user scenarios include setting up Wi-Fi connection of the D310F to a nearby Wi-Fi AP, triggering an event to the D310F for a short event video clip recording and uploading to a cloud server, or taking an immediate snapshot from a vehicle tracker. The D310F provides a set of instructions (OTUS Fleet Communication Protocol, OFCP) for the vehicle tracker to issue commands, take responses, receive notifications, and return acknowledgments with the D310F. Please refer to the OTUS Fleet Communication Protocol document for complete OFCP instructions.

In some cases, Wi-Fi connection may be broken due to bad Wi-Fi signal or interference. The D310F will report the connection failure status to the external device. The external device can then resume the connection by issuing a re-connection command.

System Connectivity Diagram

Diagram Description: A network diagram illustrates the system architecture. The D310F Network Connected Camera connects via RS232 to a Vehicle Tracker. The Vehicle Tracker communicates via 3G/4G GSM to a Cloud Server, which hosts RTMP/HTTP/FTP Servers and a Fleet Management Center. The D310F can also connect to a local network via Wi-Fi. The diagram shows data flow for Event Video/Live Video (Wi-Fi -> 4G LTE).

Typical User Scenarios

1. Fleet Management Platform communicates with the Vehicle Tracker through a 3G/4G channel.
2. The Vehicle Tracker sends Event Triggers to the D310F Camera via RS232, and the D310F can detect driving behavior events.
3. The D310F uploads video upon Event Triggered and Remote Requests.

LED Indicators

The dash cam integrates LED indicators to help users easily monitor the system status. These indicators include Wi-Fi ON/OFF/Connection, MIC ON/OFF, and Recording ON/OFF.

4. Introduction to Development Tool and Demo Environment for fast D310F Evaluation

As described previously, the D310F starts loop video recording automatically and continuously after power is on until power is cut off or the Vehicle Tracker instructs the D310F to execute other missions. A comprehensive command set has been implemented and deployed on the D310F. A demo and evaluation tool, "FleetDemo.exe", is provided for system designers to quickly examine functionalities supported by the D310F.

4.1 OTUS Fleet Communication Protocol (OFCP)

OTUS Fleet Communication Protocol (OFCP) is designed for communication between a Vehicle Tracker and a Dash Camera (Vehicle Video Recorder). In the role play of OFCP target user scenarios, the Vehicle Tracker is defined as the Protocol Master, and the Dash Camera (D310F) is defined as the Protocol Slave.

In a typical use case of Video Telematics, the Dash Camera plays the role of loop video recording at local storage, as well as creating event-triggered video clips and uploading them to the Cloud Server. Events can be triggered either by the Dash Camera internally based on its built-in sensors or intelligent video analysis, or externally by the Vehicle Tracker based on external connected sensors or remote commands from the Cloud Server.

Please refer to the OTUS Fleet Communication Protocol document for complete information on instruction usage, contents, and examples.

4.2 Typical Scenario

The following figure (Figure 1) shows a typical use case of video telematics, where the role of the Vehicle Tracker is replaced by an RS232 CMD Tool - FleetDemo.exe. This provides a quick way for Vehicle Tracker system designers to examine all functionalities supported by the D310F.

Diagram Description: A diagram illustrates a typical video telematics setup. A 720p AHD Camera is connected via RS232 to an RS232 CMD Tool (FleetDemo.exe). The CMD Tool connects to a local network via a Wi-Fi Router, which provides internet access to a Cloud Server.

4.3 RS232 CMD Tool

Figure 2 shows the user interface of the OTUS RS232 CMD tool - FleetDemo.exe, running on Windows OS. The core functionalities of the D310F include Wi-Fi HotSpot connection, triggering event video recording, live video streaming, snapshot taking, and video recording parameter setting.

Please refer to the FleetDemo User Guide for detailed information on how to use the FleetDemo tool to examine all functionalities supported by the D310F.

Diagram Description: A screenshot displays the "Fleet Dash Camera API Demo" interface. It includes sections for enabling rear camera, Wi-Fi Hotspot information, external triggers, camera settings (front/rear), firmware revision, date/time settings, video parameters (resolution, framerate, bitrate), image parameters (snapshot resolution, quality), and GPS data. A log area shows connection status, command responses, and data retrieval details.
