I'd prefer not to give an entry code to lots of different delivery drivers if possible.In this position I'd wait until packages actually started getting stolen before doing anything, or maybe I'd get a Ring doorbell or camera. 

SIDE NOTE / NOT AN ANSWER:  Any tax title property I own with a building structure on it and is apparently vacant, has at least one 8MP TASCO Game camera pointed at the house starting from the day I purchased tax title. 

We have cleaned out those tenants, and have security cameras, and access control pads to the courtyard to deter unwanted elements from coming by.

A lighted inspection camera/borescope costs fifty bucks. 

You need security cameras.

Do what you need to do.Can you change code on lock or change locks after their stay is up.Do you have cameras?

I do not have a Ring camera (buying one now) and when I reported it to Airbnb they basically said if I can’t prove it there is nothing they can do.Any suggestions?

Does anyone have knowledge to cameras on your properties.

His property , he can place cameras anywhere he wants . 

Or do you use a combination of something like a ring camera and schlage lock?
