Recs for cctv for your door?

I live alone in my 1K apartment, my package has been taken twice now. Honestly am about to go to the police about it cuz I'm sure a neighbor did it. The post office rang my bell so I have proof of unattended delivery (I asked for attended delivery, but they left it anyways)

Does anyone has any recs for a small cctv that runs constantly/based on movement??

I'm honestly thinking of just buying dead bugs and put it infront of my door.. but I shall be graceful for now.

Edit: went to the police and they told me to get a camera lmao
