Purchase a sign that says something like, "This property is monitored by security cameras." for future use.
In my neighborhood, when the porch thefts started, they were quickly followed by break-ins. We have Marine Corps and Army stickers on our windows and vehicles. We were the only ones never bothered. My neighbors with a fancy security system had a break-in.
When I was a kid, it was neighborhood teens who did the break-ins. Now, it's adult meth-heads who ride their bikes through neighborhoods all day long scouting. We also have home invasion robberies because there's a university nearby. That's not the meth-heads. That's jilted dealers hitting the wrong house.
What a wonderful world! Hope your packages remain unmolested and you get your Christmas gifts.
