Where To Start With DIY Home Security?
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?
Agree - I just went through the process of researching and installing an alarm, and the bottom line is that while the technology seems cool at first it is actually finicky and you are dealing with a serious pain-in-the-ass when things don't work right (your neighbors won't be friends for long when stray cats are setting off alarms next door at 3am).
Therefore I went with an Elk M1 system that is pricey but infinitely expandable into a complete home automation system and comes with an ethernet module that lets you do whatever you want in software - and that is where I will have my geek fun with it.
I went through this about 6 months ago.
I ran Linux zoneminder and Blue Iris - a commercial but inexpensive Windows program each on their own dedicated servers. The servers were single rack space Dual Atoms. I then installed a $100 eBay wireless IP camera, a Linksys wireless IP camera, A usb video capture card with 1 camera, and a regular USB web-cam so I could try each of these out in comparison.
The $100 camera was useless - terrible focus. The linksys, being the most expensive at $250 was the best, but is not an outdoor camera without additional housing. The USB camera is acceptable but requires proximity to the servers. The video camera is also acceptable.
After running the software for 2 months, I eventually settled on Blue Iris. It was $49 and a lot more stable than ZoneMinder. There were some features of zoneminder I liked, but after using both I found several instances were ZoneMinder had flaked out and I could not retrieve data/images that I would need if I was really researching a theft. The errors are very cryptic, often requiring extreme measures to determine what had gone wrong. Usually I just gave up and rebooted everything and it would start working again. The configuration for zoneminder is also very difficult, having to get various versions of video for linux V1 and V2, java applets/jar files etc all tied together. You can go with their 'ready to run CD' to avoid the painful configuration work, but then you are stuck with their Linux distribution, and I wanted to go with the current Ubuntu.
In the end, I have a system I am confident will provide me with images after an incident that will lead to an arrest. I plan on adding/replacing with more of the Linksys style wireless IP cams, at about $250 a pop as budget allows. The entire system will probably get its own dedicated wireless lan eventually. I can also browse in when I am on the road and check in on things, although that is more of a 'peace of mind' thing and doesn't really have much practical use.
Server - $300ish with 1.5T disk space, wireless hub (eBay) $50ish, wireless cams - $250ish each, Windows+Blue Iris - $150ish - reasonably expect up to about 6 cameras. This puts it in the same range as a decent Hard disk based dedicated security recorder from say Radio Shack, but with a wireless ability and lot more flexibility.
slashdot troll = you make a compelling argument I do not like the implications of.
So, SOMEONE slashed my motorcycle tires. I didn't want that to happen again since those particular tires are expensive for my bike (whitewalls). I went to Fry's and realistically spent about $2,000 on hardware. Now, I KNOW I am not going to keep all of it, but I just wanted to see what worked best for my needs. About 3 trips later I ended up with:
# $250-$350 4 channel DVR (I don't remember how much but it was the cheapest decent recorder).
# 1 $275 + tax wireless camera with receiver. (awesome quality and sound!)
# 1 "bullet cam" that is not tiny, but small enough to be hidden in plants. It is wired. Maybe $50?
I later returned the Fry's DVR and got one off of newegg for $100 +tax and shipping, though I had to provide a SATA drive that I already had.
I also spent a bit more, like $80 on 8 D cell rechargeable batteries, and then like $145 on a powermaxx (best company EVER) for a D charger with 4 batteries. Although I had a wireless camera, I had no where to plug it in. So I made a battery pack. My #'s indicate I could run that camera for at least 24 hours with consistent connection and quality, then about 12 more hours and it got dimmer, crappier video quality and less night time infrared abilities as the batteries died.
Thanks to Fry's excellent return policy, the only thing you lose is your time! But I was able to return all that went unused. Here are some things to avoid: Small/tiny wireless cameras: their quality and resolution sucks. Avoid very expensive cameras as that they'll be no better than middle range cameras. Don't worry about the DVR, they all pretty much suck. Don't use your PC as a DVR, pretty much most people have problems with it. Oh, and of all the DVRs I used, all of them had issues being accessed through the internet.
Someone ended up stealing that wireless camera, and I have that on DVR! My buddy put it on youtube for me: http://www.youtube.com/watch?v=IE0NkvA1uh4
I ended up buying another 2 of those cameras and mounted them high up and attached securely to the wall.
If you want more info on what exactly I bought, feel free to email me.
My abilities are only limited by my imagination
As someone who's been trying to whip up ZoneMinder into a marketable state for over a year now, I have to say it's not all it's made out to be. The capture daemons are brittle and crash frequently due to resource and memory leaks. When they exit abnormally, they always do so with the same code 255, and don't produce workable logs. Timestamps of " 1 january 1970" happen all the time, which mess up the timeline view of events. The web front end is arcane, spartan, and really time-intensive to learn. (E.g. clicking on a monitor's name does something different from clicking on its IP address, even though both screens go to a different subset of camera settings. The difference between a "modect with no zone" and a "monitor" is arbitrary. All the different camera "modes" are strange in my opinion. That there's ten different ways to view events is weird. And so on. It's not unlearnable, but it's far, far from usable.)
So instead of just whining, I patched a lot of these issues, along with adding some new cameras to the database and improving the translation for my native language. I sent the maintainer a pretty nice patch set, if I say so myself. Guess what? Absolute silence, never heard anything back. Which I could live with, if my patches at least showed up in the next release. But no new releases for over a year. So my patience with this project is pretty much over.
+1 on the Elk M1. The serial interface has an extensive command set. It is also accessible over ethernet, but their ethernet module is little more than a standard terminal server so you can just as easily use your own. I have written a Perl module to communicate with it using the POE framework. So you can integrate it with your insteon, A/V, etc. It supports nearly all of the Elk commands. http://www.seanadams.com/ha/automogator
Birdshot is not good even at across the room distances. It will not attain needed penetration. You don't want to hurt the bad guy you want to stop him.
00 is fine, slugs are better. You don't care that what happens later, this ain't the movies and you need the bad guy to stop now.

An awl could be almost as effective in the right hands, but it requires you to get much closer to the intruder and therefore increases risk
Not of you shoot a bundle of them from a siege mounted crossbow.
(Apologies to Sir Terry for stealing Detritus' weapon of choice).
So rather than pay for your own security, you prefer to let everyone else pay for it after your house has been robbed. How very philanthropic of you.
You betray your lack of understanding of simple economics. The insurance company isn't interested in subsidizing you. They will charge (to the very best of their penny pinching knowledge) exactly what they expect to pay out in claims, to a person with similar income, living in a similar apartment, in a similar neighborhood -- plus a comfortable markup for their trouble.
If you choose a homeowner's policy with a sensibly high deductible, then you're covered for catastrophic losses (the only really necessary role of insurance, for anyone with a shred of financial sense), but you're not on the hook for the (rather silly) folks who think that an insurance policy should protect them from anything and everything unfortunate that might ever happen to them. Not only that, by choosing such a sensible policy, you're also only sharing your risk with similarly sensible people.

Home burglary is almost dead. What's to steal? Any TV that can be easily carried has zilch resale value. Anything with a CRT has negative value; you have to pay the recycling center to take it. Used computers have little value. Nobody keeps much cash around any more. Cell phones are usually in someone's pocket. Who has real silverware today? Used kitchen appliances are nearly worthless. Same for used clothing. Used furniture? No market there.
In the current recession, pawnshops are currently choked with stuff they can't sell, so unloading stolen property is tough.
I just looked at the crime map for my area, which is an urban area of about 100,000 people, ranging from very poor to very rich. About ten burglaries in the last month, and only one was a residence. The rest were break-ins into vehicles. There were more attempted burglaries with arrests than successful ones.
When we signed up for $240/yr monitoring, I left specific instructions. "If the alarm goes off, call the police directly, not us or any contact. I will pay any false alarm fine. I live 2 min from the police station, so there is a chance of actually catching someone. Is this OK?" The answer was "You are the customer"
So, we went on holidays, game my mom the code, and a passcode if she tripped the alarm. Warned her that if she did expect the boys in blue. She is 81, was nervous and sure enough she tripped the alarm. So instead of cops, the security company called the house. My mom was flustered, couldnt answer the security question, but the monitoring agency figured she was too old to be a crook and told her how to reset the alarm. They couldn't understand why I was furious and canceled, after all they saved my mom an embarrassment.
so now, I purchased a couple of IP cameras that motion sense and an email to my gmail with a picture. As long as I have my phone, I see who is entering within a few minutes or less (typically 20s). Also makes it very hard for your kids to lie about what time they came home. The 4 cameras cost me $80 each on ebay, and I connected them to my wireless network. I can also at anytime now log into a web page and monitor the surroundings. So even in bed, I grab my iPhone, and have a look outside if I hear a noise.
We also did the 2 big black dogs. They are now part of the family and a great deterrent.
