I'm developing a system for smart entry/access solution for academic staff offices as my Masters' Thesis.

Well this would be up to you, you need to sort out your project first ,so size, cost, camera needs, etc... are up to you to decide. Just to sit by a door to type one, I would think any tablet you can find will work.
