Are any crimes being committed or are you just trying to hide the money from burglars? If so, just get a fire proof safe installed in your house, they can secure it anywhere pretty solidly (if someone tried to take it it would be VERY hard to get it out). For maximum security, also get a GPS tracking device installed inside of it so if someone does manage to get it out of your home (very unlikely) you can show the authorities the location of your safe (pretty hard to actually OPEN a fireproof safe, especially if you get one with finger print identification or something similar).
Very high tech, I know but if you are just trying to protect money and valuable that are YOURS inside of your own home, then having a fire proof safe is the way to go, with all of the added stuff I listed above.
