Help me select a board

I need to develop a device or system with a camera that can be placed on a door. This system will take photos of people passing through the door and upload them to a cloud server. It will also be capable of recognizing individuals. For example, if a known person passes through the door, the system will recognize them. If an unknown person passes through, the system will mark them as unknown. To achieve this, I'll need to provide the system with images of known individuals, which it will use for identification. After each entry, the system will capture a photo and upload it to a Linux server running on the cloud, storing all relevant information such as time and date in a file or MongoDB database. If the person is recognized, their name will also be stored, which can later be displayed on a web portal. Which rassberry pi model should I use for this?

Also I am little tight on budget

Should the Pi with camera only take the picture and upload it? Or should it also make the adjustment?

Adjustments like?

Currently the main goal is to get the photo and upload it onto the cloud where the recogniton can take place.

Then a Pi Zero 2 or even a Pi Zero will suffice.

Oh, is it capable enough?

Sorry if thats a dumb question, I am new to all of this

Sure, you can even use it as a webcam, so yes, taking and uploading photos is an easy exercise for the zero's.

Awesome, do you have any recommendations for the camera module?

Awesome, whats the power supply I should use?

Or wait

I need a battery

5V 2.5A If no socket is available, yes. But a power bank also works.

Awesome, thank you for the info!
