Any piece of equipment weighing more than 50lbs will probably deter a burglar -it's tough to run with a 50lb pack - so buy heavy gear :-)
Seriously, I was once told by a guy who lived in a high crime area that all he did was to display Radio Shack security stickers on every window on the ground floor
He was never broken into while other houses around him were always getting hit
The so called "professional thief" will not be deterred by anything, but then they are only scoping houses with more serious valuables that are easier to carry.
Give the stickers/signs a try.
