Ask Slashdot: Linux-Based Home Security 212

Grady Martin writes: I got a new job. Everything about it is perfect, except for one thing: The overwhelming majority of affordable housing within driving distance lies in an area known for its high crime rate. A home security system would afford some peace of mind, and a system whose code I could tinker with would afford even more. What Linux-based options are available? What experience do you have with such systems?

With dual-path reporting minimum: smoke detectors in every bedroom plus one additional per floor hallway, wired sensors for every perimeter door and window, glass break sensors for every window: motion sensors covering major walkways, and high-value areas.

But, it was crude, finicky and not very reliable which meant it required constant monitoring and care. But, for years, anything better or off the shelf would have cost thousands or tens of thousands of dollars.

      As someone who has installed dozens of different security systems, I agree wholeheartedly. DO NOT go with half-baked DIY system.

      Look for multi-zone systems by Moose, Ademco, Honeywell, or other security companies. I don't recommend wireless systems for multiple reasons- they can be jammed and the batteries go dead at the worst possible times. If you absolutely have to use wireless components, use the minimum possible and hard-wire the rest.

      Look for systems that have "home" and "away" modes.
      Mount the panel in a secured location (locked closet).
      Run the siren wires through metal pipe all the way to the siren (especially outside). Your alarm system will be useless if a $2 pair of wire cutters can be used to clip the siren wires.
      Mount the siren high up in an inaccessible location or cage it.

      There's a lot more to it than this, but don't go cheap, avoid wireless if possible, and get a solid, programmable system.

    If you're constantly checking your cameras and your feeds, and waiting for notifications of motion, that ain't peace of mind. Peace of mind is specifically the opposite -- i.e. not checking, not being notified, not being worried that every time you're underground or in an area of poor reception that someone is breaking into your home.

    Peace of mind is knowing that it's someone else's problem. That means that the alarm doesn't go to you, it goes to someone else, like an alarm monitoring company, and that they'll deal with the problem -- including calling you as much as it takes to reach you. That means you can leave, go on vacation, go to the movies, and not care.

    Especially considering that high crime rate is less of a problem when you aren't home -- because you aren't in any danger.

    Just put up entry contacts -- doors, windows, glass-breaks. Motion sensors are generally irrelevant if you have any ambulatory pets. Then let it be someone else's problems. Cameras fight insurance fraud, but do nothing in terms of security, unless you've got someone watching the feeds.

    And damn it, befriend your neighbours, ensure that they know your routines and your vacation schedules.

    Beyond that, you aren't going to stop Ethan Hunt, no matter what you do.

Then spend about 30 seconds rifling through the house looking for valuables and then get in their car and run. The security system did nothing but make noise, and yes the cops were called. So what. Even if they would have been able to react immediately they would never have been able to get here in time.

No one wants to walk up in front of the cameras, and yes I know they could wear balaclavas or some crap, but they can't walk around the neighborhood like that without someone calling the cops, and the whole idea is to be inconspicuous.

Even if you think some fighting classes are worth it or your a big guy, just don't be dumb. A gun doesn't care and neither does a drug addict.

    I'm assuming you will be renting an apartment? Cameras are your best friend. Setup a few hidden inside cameras inside which will catch someone wandering around tearing up the place looking for valuables. Keep them low and head level if you can. A raspberry pi and web cams will satisfy your Linux craving if you go that route. Use a big USB key, 128GB+ to record on a loop. That or get fancy and make a cloud setup for remote access and recording.

    Make it look like someone is home. A light coming on if a loud noise is made or window/door is touched will help. Arduino project perhaps? Maybe send a text if an event comes through. Then use your phone to connect to your web cams to have a look around. The sound of a dog barking is also pretty damn good. Get a big ass dog if you can. No crack head wants to mess with a dog. Dogs, and good outdoor lighting are the best security if you ask me. Plus, you can walk the dog to stores and no one will mess with you.

    Oh, and leave some money laying around in your house. Most break-ins are by drug addicts. If you have 60 bucks on the kitchen table, hopefully that is all they want and they will get the hell out. Keep smaller electronics out of sight like gaming systems laptops and tablets. They go for the low hanging fruit. My friend had his car broken into in a real bad area populated by homeless drug addicts. The back of his car was all computer boxes will Dell and HP printed on them as he was a travelling service tech. They broke his window and stole his ashtray which had a few bucks in cash and a bunch of change. Didn't take one box or the fancy radio. They don't want to fence or pawn shit if they can get cash. Drug dealers take cash only.

    • I think you mean "be wary."

      As a long-term Detroit resident who happened to be white I'd be more concerned about a white neighborhood. Black criminals in a black area will mug you, steal from you, and occasionally threaten your life if you're white; but they will almost never actually physically hurt you.

      They aren't stupid. They don't want to actually hurt anybody (Homicide is a lot harder to evade then the burglary unit, or some patrolman investigating a mugging), except possibly other criminals, and it's n

      If you're not white trash (i.e. you know the difference between "weary" and "wary" and are sick of ignorant fools who don't, I can guarantee that you'd also be weary. ;)

  • The problem is really: Do you want to be managing this stuff yourself? I know, when I get home, the last thing I want to happen is some problem with a security system that I'm the only one who knows how to fix.

    There's no harm in joining modules, but doing everything from integration to day-to-day tasks on a computer that you'll have to manage? That's a pain in the butt.

  • Besides the physical security, there's also getting the neighbors to know you. They're much more likely to call the police, or to notify you of vandalism, if you've established contact with them. They'll also be more willing to feed your pets, pick up your mail when you travel, or let you know if the local kids, or more organized gangs, have been making trouble, if they know your name. And doing them similar favors is a good investment in making the whole neighborhood safer.

  • You've received lots of advice on this forum... some good... some not so good but to answer your question: OpenHAB.org
    OpenHAB is a Java (platform agnostic) open source home automation software with bindings to several hundred different security and home automation hardware sets. If you decide to build a system, it would be a good platform.

  • This is 1000x more effective (literally) than ANY electronics you can buy or build.

    • Not. Burglar hit my home this summer and got around my alarm system. The dog sat there and did nothing. Not a damn thing. One fucking job and the dog didn't do it.

      I can forgive the alarm system failure. We missed a sensor area. I'm angry. But that dog eats and sleeps and craps and hangs around and demands expensive canned food and yet she can be bothered to defend the house? For that I am betrayed.

      • A dog is right there and is HARD to fool. Security systems have, as you discovered, myriad flaws. Beyond that the cops basically figure 99% of all alarms are false, so they're dead last dispatch priority. If you're VERY lucky they get there 30 minutes later, if they bother to show up at all. The average crack head is in and out in 5 minutes or less, so all that fancy alarm hardware and expensive multi-year monthly contract monitoring, worthless.

  • These are the three aspects of what you should consider.

    • Deter = indicate to a potential thief that they would be better off going somewhere else. It could be a "Protected by ACME Security" sticker in the front window or sign on the front lawn, even if it's not backed by anything else. It could be one of those devices that makes lights flash like someone's home watching TV even when nobody's around. You get the idea...and it's also a component of an existing security solution that actually does something,
  • I've got a fancy security system, IP cameras, and a dog. And a burglar still got in this summer. The alarm didn't trip. The dog didn't bite and the cameras, well, he laughed at them. What finally stopped this guy was me coming home to him inside my house and punching him in the face a few times.

    This is a long way of saying even the best systems can be bypassed. If a human spent a lot of time planning it out, somebody else will come along and go "poke" and unravel it all.

    That is the only company I know that has Linux basis. You can do it yourself, good luck however getting an AHJ or insurance company to accept it. And in most jurisdictions you will need code compliant central fire, CO and smoke detection in the entire house

  • Go meet your neighbors, make some friends, and bring the neighborhood up. Throw some potlatches. Maybe help some neighbor's kids code, or help 'em with their homework.

    You don't need a security system. You need a nicer neighborhood. So get to work....

  • When you are *present* on your property, a dog and a gun are simply the best protection for the price. A dog is equivalent to an advanced machine learning system that can tell when things are out of the normal. A pump action Mossberg has an incredibly low mtbf. The best approach to security is layerd: Dog, shotgun, emergency plan, and basic security system. Don't try to overcomplicate it!
  • Do you want a security system or a hobby? Find a professional and let them worry about whether it's been designed and more importantly installed properly.
    That said, before you turn your home into a fortress might I suggest you buy a copy of Ground Control [theguardian.com] a book about British urban planning which has a lot to say about the downsides of "secure" homes.

    So you move to a shitty neighborhood. You drop $5k on miscellaneous security stuff -- locks, alarms, door upgrades, etc. You still get nicked to the tune of $1k per year in out of pocket costs plus extras like door or window repair. And the continual aggravation and paranoia. Plus you drive out of your neighborhood for everything, since shitty neighborhoods have shitty stores and restaurants.

    So you commute instead. The extra driving is a continual hassle and costs extra money for fuel and wear and tear. But this is balanced by no paranoia or break in hassles. You spend the security money on a better car or a more efficient car. You drive less overall since the stuff you want is close by.

    Building a fortress in enemy territory is kind of appealing in a post-apocalyptic way but only if you're there all the time.

  • ... the police chief told my daddy that the giant dog is the only legal protection. If he eats a burglar it's OK but if you kill a burglar it's a crime. Russian law allows killing the killer, not the burglar.

    The second means of protection was a flare launcher. The flare easily burns all the guts of a burglar while it is not legally a weapon, so it's not a crime but only a misbehavior to keep it, and flares are sold w/o license.

    And the third: A wireless signal to the police. Prices are quite affordable, prop

  • So, physical security needs to accomplish, in chronological order, the following against the threat of a potential intrusion: 1) Deter. The area you are trying to protect should ideally scream "Try somewhere else." Steel doors, solid frames, deadbolts, restrictive window coverings (bars), visible tamper proof cameras, etc. There are also a number of devices available these days designed to make a home look occupied, Google "Fake TV" for a number of cheap products designed to make it appear as though a TV is
