Ask HN: Is RaspberryPi and flask and opencv a good solution for office entry

Hello All, one of my clients asked me to build a solution for their office entrance and attendance logging.

They want to use Raspberry pi + python flask + opencv

I can build them that solution that's not an issue.

But is it viable or required to do that ?

Or are any existing solutions better ?

    Raspberry Pi 5 lacks video encoding, so if the solution is meant to provide live streaming while monitoring multiple entrances, then your CPU may struggle.

    One of the newer ARM SBCs utilizing an NPU might be a better foundation for this.

    Have you tried Frigate with a Coral TPU on an Intel N100 system? Works great and could probably facilitate this use case better than an ARM SBC.
