To ensure high data accuracy, Density conducts periodic data audits, which amount to approximately 80 MB per device, per month. During these audits, the sensor sends raw depth data files to its cloud service, which is then analyzed manually by the Density team to train our machine learning algorithms. Because Density’s technology is anonymous by default, at no point during any of these audits is personally identifiable information processed available.

Note that the amount of data used during an accuracy audit may be higher than 80MB during an initial calibration period after the installation, during which the device’s algorithms are initially trained and configured for accuracy in each particular doorway. During the calibration period, bandwidth consumption may vary based on variables such as amount of foot traffic and network environment.
