Michael,
I'm sorry about confusing the wrong TV show in regards to the "Zombie Special".
On a side note about home security, I have had the pleasure of living with some older people as roommates in the past (I'm in my 50's, so they are... lets say (edited to be politically correct)... elderly). I'm not sure of the reason, but many of my roommates at that time seemed to be brought as a young people, that if someone (I mean anyone) knocks on your front door, you must open the door and see what they want! I tried on may occasions to outline the dangers of these actions, but 5 minutes later, they were opening the door to anyone (newspaper salesperson or active shooter, it did not matter to them). I finally installed a dead bolt locked on both sides. There were 5 other exits for them, so I was not concerned about a fire escape/safety issue. After installing the new dead bolt (key locked on both sides with no key), someone knocked on the front door. Afterwards, I asked one roommate why they did not use a different door or the garage door to greet the stranger. The roommate replied " They did not knock on the garage door!"

The point of this story is, video surveillance is very helpful to you and your family in identifying who is at your door. I have found that some strangers that knock on your door and they see you through a window, will almost knock you door down if they know someone is at home and is not or refusing to answer the door.
Of course you can do what my neighbor does, if anyone knocks on her door, she just calls the police! The police arrive at her home about 5 times week, she always claims that someone is trying to break into her home! Someday when she truly needs assistance, the police will be the last to arrive.
Michael and Mike, I will be looking forward to your new shows on home and personal security tips.
Thank You, keep up the good work!
