Where To Start With DIY Home Security? 825
secretrobotron writes "I'm a recent university graduate from a co-op system which has kept me on the move every other semester, so I've never really had a permanent place to live, and I've never had the opportunity (or the capital) to buy expensive things. Now that I'm working, those restrictions on my life are gone and I'm living in an apartment with things I don't want stolen. I would love to build a DIY home security system, but I don't even know where to start since Google searches reveal things like diysecurityforum.com, which help only to an extent for a curious newcomer. Has anybody out there successfully built a home security system on a budget? If so, where did you start?" Related query: When similar questions have come up before, many readers have recommended Linux-based Zoneminder (last updated more than a year ago); is that still the state of the art?

It sounds like you're not too keen on Accepting it, so lets consider the other three options. The magic here is to budget for it. Don't spend $1M to protect your $1000 stereo.
Chance mitigation is all about making it less likely for you to be invaded. This is about taking away temptation (eg tint your windows, good curtains), making entry harder (locks, security screens), and discouraging attackers (those cool stickers that threaten trunk monkey attack)
Damage mitigation is about reducing the damage once they're in. Alarm system. Connected to local security firm. Be prepared to pay $1 per day for monitoring.
Insure it. Nuff said.
There is nothing in this about video-ing the perps. There is nothing in it about having a gun, or traps or anything weird. When you assess the possible outcomes, those things don't reduce your loss, and likely increase your trauma.
Good luck!

The odds that you will get your stuff stolen are pretty low. Security systems are mostly a waste of money. Just get some realistic looking ADT stickers (from eBay) that will make the thieves think you have a security system. Having an actual system will get you ZERO extra security, just costs.
In case you get your stuff stolen, get home insurance, they will give you money and then you can buy newer toys! Actually, get insurance anyway, if the building burns or something and you are responsible, you really want insurance.

Better auditory detection capabilities.

More reliable than any electronic equipment.

I've heard of some straight up horrible things happen to dogs when their owners were away. One of my friends came home from work a few years ago and found his dog with a screwdriver through its head. I've heard of oven cleaner being used. Truly fucked up.
I'm a decent sized guy that has been attacked a couple of times by dogs as well (a pit and a doberman), and while I have some good scars, I wasn't ever too worried about handling myself against them. I am scared of rottweilers, but I can easily out run one of those fat fucks. Multiple dogs are really needed to scare off an experienced thief. Even then, don't grow too attached to a guard dog. They don't have great chances if someone wants what you have.

The likely cost of dog, plus regular veterinary maintenance, plus daily feeding, plus pet-sitting while away on holiday or business is substantial. (Remember, you can't board your security system at a kennel, or even store it at a friend's place while you're away -- it doesn't work, then.) You're out of pocket for quite a bit more than the typical homeowner's insurance policy, and the cost of dog food is probably comparable to most security system monitoring charges.
Meanwhile, the typical security system doesn't need to be walked twice a day (rain, snow, or sunshine), isn't going to shed on all of your clothing, and won't chew on your shoes.

Dogs are useful and all, but bear in mind that your neighbours won't be very happy if the damn things bark all night, or whenever a pedestrian walks past your house. They will also be unimpressed if when you take the brutes for walkies you let them shit all over the sidewalk, nature strips, and their front lawns.
OK, so maybe everyone else in your street should stop being so whiny about your lovely, loyal pets. This is true, but it's also true that if I saw a burglar breaking into the house of the redneck with the big noisy dogs that bark the whole damn night and shit where I walk, I probably wouldn't report that burglar.
Social engineering. Make friends with the people next door, and look out for each other. That nosy neighbour who stays at home all day can be your greatest security asset if you're on good terms.

You do realize that most doors can be kicked down by a moderately healthy guy? Many people have locks on their doors that are worth more than the door. If a person is going the route of barring windows and buying good locks for the door, we better remind them to really LOOK AT their door. Is that door really suitable for use as a security device, or is it more suitable for a dressing room, as prevention of voyeurism? What holds the door and it's frame to the studs in the wall? What secures the door itself to the door frame? Believe me, six or nine little #2 phillip's screws aren't going to keep me out of anyplace that I really want to be.

Seriously.
Any security system, starting with a locked door, is simply a polite request to have your things left alone. Someone who chooses not to will not.
If you're techie enough to have real data (including music, etc.), then make sure you have daily offsite backup. The hardware is trivial to replace (given money), but getting your information back requires an offsite backup.
Anything else and you're basically wasting your time.

I subscribe to the theory that thieves are lazy, they will seek out the easiest target.
Technology will only get you so far. Video surveillance will show you the perps after the fact. Alarms might scare off kids and amateur criminals. Shotgun traps will get you thrown in jail.
If you have ground floor windows, plant thorny bushes in front of them. Roses look nice. Invest in motion detecting exterior lighting. Put up a fence. Reinforce your doors. Install better locks. Make sure all points of access are easily seen by your neighbors and the police. Don't leave expensive stuff where it can be viewed from outside.
The goal is to make your place a less attractive target than the neighbors.

So, I read the FAQ.
It's atomized pepper. Does that mean they actually break down the molecules? Apparently so as without cleaning up (it's optional!) there is no harm for humans, cats and dogs after three to four hours. Your toddler and pets will appreciate this fact as they are a lot closer to the ground when that stuff is stirred up again and again.
Also, even though it is a fine-grained powder based on pepper, it's not flammable.
That, or the FAQ is a steaming pile of lies and half-truths.

Agree with the basic sentiment of preferably not killing anyone ever. But are you really sure about that? Perhaps when asked again *at the end* of those two years? Or *at the end* of 20 years, when you still have half your pay check seized for the damages awarded to the intruder(s family), even though he went out of his way to mess with you, had the worse outcome of the fight but a better lawyer in court?

You spend x hundreds of dollars on a "security" system, only to have part if it stolen. You end up in one of the most optimistic situations for the system: using your "security" system to capture the perpetrator in the act of theft. Hell, you even have the guy's face and voice on video and have crowd sourced a search for him (youtube + slashdot), but you still can't get your property back.
What REAL value did you get for you X hundreds of dollars + time?
