Client Questions from Oct 20th
It was nice to spend time with you and discuss how you may make use of occupancy data and people count. There were a few outstanding questions brought up during our meeting that we thought we'd follow up on in more detail.
This is an unlisted page put together just for you and your team. Please feel free to share it internally, as needed.
- Andrew Farah, Density CEO
We use this technology because it provides a very rich data set and because it's anonymous.
Pictured left is a profile-image of a person holding a flat object in-scene. Each individual white dot is a depth value.
Density's Depth Processing Units (DPUs) generate this data to understand human behavior.
If Density is hacked, can people be identified?
No. Density was purpose-built to only generate anonymous occupancy data. Even if our system were somehow compromised, Density does not generate or store any personally identifiable information (PII).
The DPU is a powerful machine learning device. It handles millions of computations per second, making Density both the most accurate way to measure space and the least invasive.
To achieve this, we've invested heavily in its onboard computing and local algorithms.
What's the purpose of Density's shape and size?
The aluminum chassis and physical dimensions of the DPU are designed to support variable installation types, a professional aesthetic, and comply with safety standards.
The 110mm² enclosure actually serves as a heat sink, cooling temperatures quickly. Our thermal model assumes peak power output; therefore, we’ve incorporated active cooling and necessary space for airflow.
What's the reason for Density's angle and mount?
- To provide the device the appropriate FOV to capture all throughput.
- It is also optimal for accuracy. The orientation and distance are ideal for our algorithm and infrared illumination.
How is size related to accuracy?
The DPU's components are so high speed that if placed too closely to one another, the electricity running through them will add noise to your data. This degrades its integrity and accuracy.
For this production we've laid our traces as close to one another as we feel comfortable without causing problems to "SNR" or signal to noise ratio.
In addition to the API, can I access my data through a dashboard?
Yes. Both are available at any time during your pilot or production deployment.
You can access historical space utilization data through Density's out-of-the-box dashboard or by querying the API.
What industry do you serve?
Corporate workplace strategy & design. Density was thoughtfully designed to serve the needs of corporate teams who manage facilities, corporate real estate, physical security, and workplace technology.
How do you ensure the security of your product during shipment from a contract manufacturer?
As necessary we will employ similar methods used when shipping high-value products like the iPhone; this process is called “Secure Ship.” It can include hardened shipping pallets, full traceability, and even armed guards depending on customer requirements. Our Operations team can offer this to customers who have need for a certain level of physical security (additional costs may apply).
Will you be able to handle our scale?
Yes. We’re engaged with a Tier 1 CM in China capable of producing hundreds of thousands of units a year. In terms of our initial capacitation for this product, we will be capable of producing thousands of DPUs per week by mid-2018. Capacity can be ramped up from there depending on demand.
How accurate is Density?
Very accurate but variable based on environment. Accuracy can be affected by environmental complexity (ex: number of humans per hour, odd behavior, unplanned occlusion, etc). However, as a comparable, one of our customers installed Density on a full-floor cafeteria. Over 90 days, the 5 installed DPUs counted over 1 million human ‘events’ (entrances and exits) with a combined accuracy of 94.2%.
Can Density measure a space with many doors?
Yes. With 1x DPU above each primary entryway, you can associate all units with the same space. Additionally you can define “spaces of interest” within your Density network.
Can Density be ceiling mounted?
Yes. We sell a specially designed modular mounting bracket, affectionately called the "backpack." The backpack makes ceiling mounted installs straightforward.
How wide of an entryway can Density support?
Currently, up to 8 ft wide entrances.
How does Density handle system security?
Why does counting people require powerful computing?
People do strange stuff in doorways. See How Density Works to learn more about how our algorithm makes sense of it all.
