Always have a door/front porch camera installed with a screen in a central location. Dont open your door until identifying the threat (yes, the cops count as a threat). Dont open the door groggy from sleep, take a second and wake up. Use an intercom to address them so you dont…

This is NOT a suggestion. Dont do it. But I saw a house that had flood lights installed that would blind anyone approaching the house.
