  Hi Will Sommerville  The regulatory certificates for RealSense camera products can be found at the link below, though do not include a certificate of volatility.

  There is also not a statement about volatility (whether a device's memory is volatile or non-volatile) in the data sheet document for the RealSense 400 Series camera range.

  The cameras contain two circuit boards, the Depth Module and the Vision Processor D4.

   

  There is a 16 megabyte (very small size) SPI serial flash memory on the camera's Vision Processor D4 circuit board for storing the camera's firmware driver.  The recommended part number is IS25WP016 or equivalent.

  There is also EEPROM flash memory on the camera's depth module circuit board for storing the camera's calibration data.

  Flash and EEPROM memory is non-volatile.

  Hi MartyG,
  Can you also confirm that the memory is not user modifiable (aside from the firmware and calibration functions they are designed for)?

  I confirm that the flash memory is not accessible by users except for the purposes of saving firmware and calibration data.  There is also a requirement that a firmware file is digitally signed by Intel, otherwise the firmware will not work.
