Great idea... Started that some years ago when I got out of guns and into cameras. If nothing else it keeps everything together and the kids out....
Liberty is fine.... I have FT KNOX which is about the best on the market.... I'd say if you get something in the 800lb range you should be OK no matter what the brand.
If you know how to move it, they are easy to move.... Videos on UTUBE or PM me and I can explain. Similarly if THEY know how to move it its easy to move So you need at least one bolt into the floor. Place it in a closet if its smaller... Or somewhere out of casual sight where visitors to the house can't see it..... Also a SIGN on the front that says NO GUNS INSIDE CAMERAS only may discourage theft.....
Last, looker at the bargain shopper newspapers for a used one.... They don't wear out and sell pretty darn cheap used. $1000 should get you a very good lifetime used safe. BTW, no matter what they say, they are NOT and FAR FROM FIREPROOF. (they are ways to inprove that if you want, pretty easy too...
Also before you install, there are things to prepare. If its on a carpet, cut a piece of chairmat to fit under it (slightly smaller than safe so it doesn't show) to protect carpet from rust). If its on concrete, you need a rubber mat under it to protect from cold and hence moisture. Need an outlet installed NEXT TO THE SAFE (not behind it) to plus the dehumidifier and lights into... There are probably a few other things to mention but can't think of them now....
Immediate solution.... Tether your Pelican cases (I do it in the car).... Attach a bolt to something solid.... Go to HOME DEPOT and buy a couple of decent padlocks and a security cable (next to padlocks)..... Attach locks to cases and string cable through the locks.... Makes it hard to run off with cases bolted to the floor or door frame, etc......
Best wishes..
