True, but from the few school sessions we had, about breaking locks (for comsec reasons), the time it takes someone, to crack manual dials, most thieves won't have, unless they break into a home and TAKE the safe with them..
I wonder, if they've ever made a key lock that can't be picked??
True, the determined will always get in, even if they just have to break it to get in it..
We had a gal when i was stationed in Bahrain, who had her home stateside broken into. HER two safes (One for her coins, one for her important documents), had a manual dial safe covering it up, then she had the electronic lock to get in. Cops said the criminals cut into the first lock cover, but by the time they saw the second, the just left her home with what loot they stole already. Compared to two other homes they broke into that they were able to get OODLES of stuff, because the owners had NOT ONE thing under lock and key...
Would you care for a side of fries with that...
Never thought of bolting it to TWO walls (in a corner) AND the floor...
Before his death, my Stepfather was considering a retirement side-job playing with guns, in order to meet BATF guidelines we had to put security gates on all the windows of his house, bolt down the safe storage and he went a little bit 'extra' to make sure-part of that, was bolting gun safes into corners on three sides to make them more difficult for someone unauthorized to remove.
The basic idea remains the same though-you can try security-through-obscurity, (safe that looks like something else), Security through structure, and so on-but the central key is that, if you arne't spending the budget of a third world country, all your measures aren't to stop professionals, because pros know how to get past them.
The measures are to block
Opportunistic thieves. a Junkie looking for something to pawn for their next high is going to focus on what's left 'loose', followed by what's not very well locked down, so the longer it takes for your intruder to get past your 'ordinary' security measures, the better those measures will protect your goods-criminals don't inconvenience themselves if htey don't have to, or they wouldn't be criminals.
Hence why your deadbolt on the front door of your house is the best investment you can make on a cash-to-effect basis-if the door is locked and the lock is a pain to overcome, that's going to freeze out a lower tier of crook. the more time they have to spend getting at anything they can re-sell? that's going to deter a slightly better level of crook looking for an opportune score.
give someone sufficiently determined enough time, however...
anyway, my vote is pick a corner in your closet, bolt it floor-wall-wall. it's more bolts, sure, and you still have to secure the actual access to the safe, but depending on what you're using, that's going to take time.
as for the question of Digital versus Mechanical locking schemes? do your own research there, and keep in mind that there has never been, and never will be, a lock that someone with sufficient resources can't overcome if given enough time or resources. Your locking safe is to inconvenience the opportunistic criminal, not the dedicated professional.
