I've looked at safes and boxes like this in the past, main problem is that my gear usually sits right next to me in the office or living room, neatly packed into a backpack. And my camera usually lives on a table or shelf, I never put it awa. Only when we go on vacation, then I hide things in different areas, behind junk in a junk closet, inside the bed (not visible and hard to get to even if you know where it is) etc and some stuff might just end up under the dirty laundry or with laundry in the dryer.
Of course, all spots that an "educated" thief will find, but most smash and grab are just then, smash, run in, grab, run out. It's all insured of course.
I will do a small remodel soon though, where I plan to hide a large narrow junk closet inside an other closet behind a false wall. Impossible to tell from the outside, impossible to find unless one spends a lot of time and starts taking things apart. That's where my gear and other things will then hide, if I don't take it with me on vacation.
That box just screams valuable and if somebody has time to spend they will get it out or open, probably causing damage to your house. And having my gear locked in there all the time would annoy me more in the long run than having it snatched and replaced IF that even ever happens.
My parents house was robbed (despite security glass with film and all that, they used a patio brick and spent some time smashing). Like the cops said, if somebody is determined to get in they will.
I did however do one thing, I copied the logo of a local alarm company and made clear stickers on my printer, put those on doors and windows. Just as I had a blinking LED with a battery pack installed in my dashboard of my old car. Figure if a crook doesn't care that I (might) have an alarm they'll not care about much else either. But a smash and grab will probably move on to next door.
If I really was that afraid or had big values at home, I'd get a real safe with biometric lock so I can open it with my fingerprint instead of fiddling with padlocks or numbers and keys. Yes, more expensive, but a lot less annoying. I'd get the same for guns, if I had any.
