About the Open Dashcam

The Open Dashcam (ODC) is an open source dashcam that is approved to operate on the decentralized mapping network. Hivemapper is building the first dashcam - the Hivemapper Dashcam - based on the Open Dashcam, but as an open source project other hardware manufactures can build their very own version of an Open Dashcam compliant device. We hope that others will build versions that are optimal for certain markets in the world, especially Asia, Africa, and South America.

What problem is ODC solving?

  1. 1.
    "Set it and forget it" experience. To enable passive collection and support a large set of contributors on the mapping network, the experience must be "set it and forget it." The collected imagery must be automatically transferred to the Hivemapper Network.
  2. 2.
    Location authenticity. The Hivemapper Network must trust that each device collecting on the network is providing accurate and authentic location information.
  3. 3.
    Open source. By making the device fully open source, hardware partners can create, market, and sell unique dashcam devices for specific use cases and markets.

Key Capabilities

  • Open Dashcam must collect 4K imagery or above
  • Open Dashcam must dynamically adjusts frames per second to avoid over-collecting.
  • Open Dashcam must automatically transfer the collected imagery to the Hivemapper Contributor App where the content will be further compressed and uploaded to the Hivemapper Network over Wifi.
  • Open Dashcam must encrypt the GPS data to ensure the contributor's privacy and ensure the authenticity of the location data.
  • Open Dashcam must collect and transmit information about seen Helium hotspots to verify location.

Why is it open source?

  • Enables other manufactures to incorporate support for mapping within their own dashcam.
  • Enables the community to verify that the Open Dashcam is only collecting the information it needs for mapping, and not secretly recording your conversation or something else nefarious.
  • Enables the community to enhance features, fix issues, and generally contribute to the project.

Tech Specs

Below are the tech specs for the original version of an Open Dashcam compliant device that Hivemapper is building. Soon, the Hivemapper Foundation will detail the minimum specs required to operate a dashcam on the Hivemapper Network.

Camera Specs

  • Imager: Sony IMX477 - a high resolution, rolling shutter CMOS image sensor
  • Resolution: 12.3 MP
  • Sensor Format: 1/2.3"
  • Sensor Type: Back Illuminated CMOS
  • Shutter: Rolling Shutter
  • Frame Rate: 10hz
  • Lens: CIL023
  • IR Cut Filter: T=50%@650nm+-10nm
  • F#: 1.8 Fixed
  • Vertical FOV: 93.9 degrees
  • Horizontal FOV: 110 degrees
  • Distortion: <5% TV
  • Imager Circle: 8.5mm

Image Processing

  • Raspberry Pi Compute Module 4
  • Quad-Core Cortex-A72 (ARM v8) 64-Bit SOC @ 1.5GHz
  • To ensure the Open Dashcam does not needlessly over-collect the Open Dashcam and Hivemapper App will work together to ensure that frames collected while a vehicle is stopped or parked are not collected.

Connected features

  • Built-in Wifi: 2.4 GHz, 5.0 GHz IEEE 802.11 b/g/n/ac
  • Lora: Semtech SX1262 LoRa Transciever and support for Helium
  • Lora Antenna: 915MHz, 860MHz, 490MHz, 433MHz support planned depending on region
  • GPS: U-Blox NEO-M9N or similar
  • GPS Antenna: Kyocera AVX 1004322 or simliar
  • The Open Dashcam connects to Hivemapper App via APIs to transfer imagery and Hivemapper App is responsible for processing and uploading to the Hivemapper Network

Sensors, storage, and power

  • IMU: critical for dynamically adjusting FPS
  • eMMC drive: Min of 16GB. Stores operating system image, and can store minimal amounts of imagery
  • EEPROM IC: for encryption key storage
  • Power: 9-28V
  • Current: 0.5A @ 12V

Firmware

Hivemapper App Integration

The Open Dashcam is being designed to connect to the Hivemapper Contributor App enabling backhaul (aka upload) of the data to the Hivemapper Network.

General

  • View live imagery - from the Hivemapper Contributor app you can view the live imagery feed.
  • Warnings - the Hivemapper Contributor app will warn you if the Open Dashcam is not configured or mounted properly.
  • Storage - view the amount of storage currently available.

Data offload

  • Transfers imagery - the primary capability is to transfer imagery from Open Dashcam to Hivemapper App. The app will show yow how much imagery has been transferred from the Open Dashcam to the Hivemapper Contributor App over the past day, week, month.
  • Limit imagery transfer - one can limit the frequency and amount of imagery that is transferred.

Mounts

There are four approved mounts when contributing with a dashcam on the Hivemapper Network. The Open Dashcam must support one or more of those mount positions.
