The vampire is hardly going to be hanging out in a cardboard box just waiting for someone to come along and stake him. He'll have some prep and emplaced defenses too.
Things I'd think about, if I were a black court vampire:
I don't have a wizards tech problems, so plenty to electronic security. That will work versus more mundane threats, and non-wizards. And any wizard coming for me will cause it to fail, meaning that I'll have some warning.
Simple physical barriers. Some heavy metal doors and similar stuff between me and the world give me more time to get organized, if someone attacks me. Sure that can be broken, but that take time and energy.
Using my mental powers on people tends to make less stable results, by a pack of Renfield dogs is probably a fine thing to keep around long term.
So you are looking at skill 3 or 4 dogs with maybe base weapon 1 teeth, with possibly some inhuman stats. And they know how to stack maneuvers against a single target to bring it down quickly.
Some more intelligent stuff to guard me would be nice too. Of course, since I'm going to be pretty much helpless during the day, it needs to be something I have a great hold over. So while simple hired security may work for my outer perimeter, I'll need something much more loyal as a last resort. Of course, if I have the knack for more delicate mind whammies, I may be able to keep some humans around, long term. If not, then I'm looking at things like bound demons, magical constructs, and similar stuff.
I'll have a selection of awesome fire suppression systems, for when they try to set me on fire. For example, I note that Halon based fire suppression systems both put out fires and make it very hard to irritating fleshy vampire hunters to breathe, something to keep in mind.
Ideally, I also have a getaway that my coffin can be stuffed into, as a last resort, and something I trust to drive me away.
-------------------------------
So, my setup might look something like this:
I have an outer perimeter of mundane guards. They have guns, radios, armor, night vision goggles, various electronic alarms, and so on. Since I can't take them over and still trust them to do their job, they aren't trusted to guard the inner perimeter. I also have some solutions in place in case they get turned against me, but they are paid well and threatened carefully, so it would probably take supernatural action to do that.
Then, my middle perimeter is guarded by a pack of 'Renfield' dogs:
The look something like:
Athletics 3, fists 3, alertness 3, stealth 3, might 3
inhuman strength, inhuman speed, weapon: 1 teeth possibly inhuman toughness, or maybe just tailor made bullet resistant armor.
Likely combat tactics are several dogs trying to generate maneuvers against you based on steath, athletics, or might and then just one or two dogs cashing in those maneuvers to bring you down.
They probably stand a reasonable chance of finding someone coming in under a veil too.
-------------
The inner perimeter will probably have a couple of bound demons on constructs to make a mess of things, something like Kalshazzak (OW p36).
And if all that fails, then I have a smarter, servitor, who knows how to drive. He'll have directions to load my up in the armored car (either one of those 'executive protection' style armored limos, or a cash transport type) are drive out of there, while leaving the whole place exploding or on fire to confuse the issue.
------------------
Remember that the vampire nest that Harry attacks was put together in something like a week, and was just there to trap him. The permanent home of a survivor of the Stokerlypse will be much better defended.
