What spy camera is smallest, and best for apartment surveillance?

I need to put spy camera in my unit, because my apartment is burglarized more than 3 times, I believe by the management and their staff, and police only did a report. I complained money times to higher ups, and nothing has been done.
I am pretty sure this people are coming back to attack me, for that matter I need to put Illusive spy camera which has audio too. Any suggestions, or better ideas?
Thank you
