Firmware versions compatibility + possibility to downgrade
Hello.
We recently bought F455 device and updated firmware. During the update we received information that stored face prints have to be deleted to continue with update. Probably because otherwise face prints created on older firmware would not be compatible with new firmware.
We assume it is possible to have face prints shared between multiple F455 devices. Based on information we received during firmware update we also assume that if we would have two F455 devices with different firmware versions, face prints stored on one device would not be compatible with firmware on other device. Therefore sharing between devices would not work.
1) Do we understand it correctly?
2) If answer to first question is yes: Is it possible to also downgrade firmware? Or is there some other solution to our business model?
We want to use F455 device as part of our attendance system solution. It means we will often deliver multiple PCs with F455 (with current version of firmware) to our customer companies. After some time our customer might want to order another PC with F455. But it also might be after few years from first order, therefore there probably will be newer version of firmware on F455 we will buy at that time (which would cause incompatibility between older devices and the new one).
Thank you for your answers, Martin Hochmal.

Hello Martin,
In the current FW versions, while downgrading and upgrading FW does not delete the faceprints, it is recommended to re-enroll users because faceprints are not compatible across FW versions. However, a new recognition model will be introduced in the next release and will require re-enrollment. We plan to finish all database and recognition changes within a few weeks and then it'll be frozen.
Only then it makes sense to enroll all people and create the final database.In general, it is a best practice to always install the latest FW versions in order to keep with the latest security enhancements, bug fixes, and new features.
Sincerely,
Jesus G.

Hello.
Thank you for the information. Is it possible to narrow time estimation to some more specific information? Do you have some probable date when will that release be out if everything goes well? Or some deadline when it must be done even if there will be troubles during development?
I am asking because as I said previously we are considering this device as part of our solution which we would like to offer to our customers. But it is important for us to know time estimation so we can decide if we should wait for this solution to be fixed or to use different one.
Thank you for understanding, Martin Hochmal.

Hello Martin,
The best I can give you is in about 1 month. However, this feature will be rolled out via a firmware update that is easy to do. You can purchase a RealSense ID device any time and upgrade the firmware when the feature is released.
