Due to frequent breaking, we now have hugh thick metal doors but what I see is that their hinges remain small and why are the hinges place outside and not inside??
Please advice
For safety from gas cutter, how about metal sandwich door with either concrete or plywood in between. Would that make the door more secure than just thick metal door as plywood or concrete prevent the penetration from the oxyacetylene torch.
My layman suggestion to the problem on safety.
I recall an article I read years ago of an actual bank vault door that were taken on by a group of burglars.
Yes, vault doors are now made with a sandwich of various material.
In this particular incident, the burglars ran out of gas for the torch trying to geth thru this layer (after getting thru a number of layers).
Unknown to them a hammer at this stage would break that particular layer
Cos it was made of some space-age material that can withstand very high temperatures but not whacks from a hammer.
I have this particular experience of a bank vault the floor space of a single storey house.
One day a huge flood occurred, water leaked thru the ceiling into the vault!!
Moral of the story...the vault was as strong as it's weakest point...which in this case...the concrete roof which was the floor slab of the floor above.
Getting thru the door would haven a long time, but if one were hack thru the roof slab, that would be much easier.
My take on the current state of physical enhancement used are only effective to delay than prevent.
Whilst a secondary security system is used (upon break-in) to alert the owner for any subsequent action.
I think it's been commented enuff here there's no way to prevent a determined thief.
Also I recall a report that ropes were left behind after a theft, guess where they entered through?
Also another posting of electrification of the obvious entrances for both owls and burglars...stepped down voltage?
How does one defeat a grappling hook attached to a 1/8 inch steel cable?
Dun know of any legal precedence of burglars killed by booby trapping.
That too can be defeated by cutting off power.
Any security gizmos require power, as such a standalone backup power will be preferable?
I figure that the least broken into BHs are the ones with a stay-in resident.
I am aware that not many will not be willing to discuss their measures in the fear of being defeated.
But a determined thief will probe your BH weaknesses until the chink in the armor is found.
I realise there are desperate thieves and brutal robbers who would not hesitate to inflict physical harm...
But if one has taken all sensible measures, the rest will be calculated and acceptable risks, similar to driving, taking a flight..etc.
Living among politicians in theiur human form is an unavoidable risk, they may bite and give you rabies or kill you thru a heart attack.
YET Perhilitan has yet to categorise parliament a zoo and the inhabitants wildlife.
Which brings me to the Wildlife Conservation Act 2010 Bill.
No one has any concerns and happy if it goes thru with the 2nd and 3rd reading in Parliament and be gazetted to become law?
