Yes, you can have a doorbell camera in an apartment. There are a few things to keep in mind when installing one, however. First, check with your leasing office or landlords to see if there are any restrictions on installing cameras in your unit. Secondly, consider where you will place the camera so that it has an unobstructed view of your door and entryway. And finally, make sure to read the reviews of different doorbell cameras before purchasing one to ensure that it meets your needs.
