Ask Slashdot: Inexpensive SOHO Crime Deterrence and Monitoring?

First time accepted submitter trellz writes "My sister and brother-in-law are self employed, and run a small business with a storefront. It was broken into about a year ago, and since then they have reinforced physical security; bars on the doors and windows, better locks, etc. Unfortunately, their store was broken into and vandalized again last week, in spite of the added security measures. Being technically savvy, I'm trying to come up with inexpensive ways to add deterrence, monitoring, and alerting to their business. They run an extremely lean lifestyle and profit margin, so the solution needs to be almost free. They do have an internet connection at the store, so motion detection, web cameras, Arduino devices, and the like are certainly an option. Ideally I would like a rock-solid alerting method. Something like an email or text to a laptop at home, or a dedicated prepaid phone, but without the pitfalls of such a solution (i.e. random wrong numbers, solicitors, email spam, etc). I'd also prefer not to poke holes in their firewall at the shop if at all possible. I was considering an email with some sort of long code or hash in the body, and then could white list that on the receiving end to key off of. The goal is to never have a false alarm based on the transmission/reception method." What advice, beyond ZoneMinder?

    Bars on the doors and windows suggests someone was pretty aggressive about getting in there - or your physical security upgrades are just insufficient. If people can still get in, and if what they take is relatively lightweight, a sophisticated alarm isn't really going to help you all that much compared to just something which makes a lot of noise.

      Yeah, a good bar system should take longer to get through than anyone would be willing to commit. My first question was, "what do they have in there? Guns or drugs?" and the second is "what are the bars made of, rubber?"

      My vote is for a cheap $50 (or less) motion detector tied to a loud speaker. Nobody wants to rob a place so loud it hurts. You could set it up to send an email when triggered or such, but that's not going to make a huge difference in the robber's response. Unless the plan is to get a $200 cheap PVR/camera security combo so that they can catch people, rather than scare them off after they've done $1000 damage to windows and bars before running off.

That's the best case image you're going to get -- stuff from usual cameras used for monitoring looks much worse. Most security cameras are completely useless. You can barely tell between a human and a gorilla on most of the feeds that catch large areas. A small storefront may leave you with a bit better image than most, but it's still way too large area of an to cover if you want to see any faces. Other than recognizing faces, what's the point? I mean, you know there was a break-in, there's no reason to look at a video recording to confirm what's obvious. Either you get faces that are recognizable, or it's mostly useless.

      You've basically fallen for the security monitoring scam: people love it until they actually need to see the images and realize they are useless.

      To get good monitoring you need HD cameras, and plenty of them. For a small storefront monitoring, you may need coverage from two 1080p webcams. They are not exactly the most inexpensive of things. Alternatively, if you believe in a bit of luck, a digital photo camera taking timelapse pictures every second may also be likely to catch the faces. I'd go for one of the Canons where you can replace stock firmware with CHDK. You can then make it delete old pictures and keep new ones in round-robin fashion.

  4. Almost free? by mysidia · · Score: 5, Insightful

    They run an extremely lean lifestyle and profit margin, so the solution needs to be almost free.

    Doing nothing has a cost too... possibly more break-ins = more lost profit. There is a potentially high risk cost of doing nothing; depending on what it is, they might be able to budget a lot of money, and the net cost could be zero: assuming the break ins are actually causing damage and hurting their business revenue.

    The idea that you run a business, and you are not willing to spend any money on security is absolutely ridiculous. You should be willing to spend an appropriate amount of money to manage the risk.

    The most important mitigation is probably to have insurance, but again... the premium may increase, the more breakins.

    This may be a matter that a security consulting firm should be hired to look at.

    Hidden cameras with a DVR may be useful to help catch the perps.... however, there is a problem: this is only useful, if responders become aware of the breakin and get there, before the thief can locate the DVR associated with the cameras and destroy it.

    Visible cameras, may be used as a deterrent; however, they are subject to vandalism.

    One of the best deterrents which should not be overlooked is a professionally Monitored security alarm system with External sounders, Internal motion detectors, Door sensors, Glass break detectors, perimeter coverage, and an alarm loop and cellular backup to a central monitoring station, that will dispatch authorities in the event of an alarm.

      Um, this is 100% a waste of money. A monitored security alarm gets rid of nobody but the dumbest B&E'ers. Even if the alarm company is listening, and verifies that a person is physically inside the premises, and phones the cops, the response time is still ridiculous [in downtown Vancouver BC, it was like 20-30 minutes]. And the thieves know it.

      $5 for stickers saying you have a monitored alarm works just as good.

      DVR's need to be fairly good to be able to positively identify somebody, nevermind at night in the dark. And that assumes the police put much effort into looking at it [it usually amounts to the detective on the case looks at the video, and either recognizes the guy or doesn't...end of video]. And does catching the guy make a difference to your business [as in, how fast does the guy have to be caught for him to still have the stuff so you get it back, as once he has passed it along, the likelyhood of ever seeing it again goes WAY down].

      And your insurance rates go up the same amount whether or not the guy gets caught [unless of course, you recover enough stuff to not bother making a claim, which is very rare].

      In general, your best bang for your buck is loss prevention. As in, preventing the stuff from exiting the store prematurely.

      For ground-level shops, try roll-shutters over the windows and doors. As a bonus, they also prevent vandalism like window-smashing.

  9. Security should be "in depth" by rusty0101 · · Score: 4, Insightful

    I'm seeing a lot of partial solutions here. Both in what has been done, and in what is being proposed. The first thing you should be doing though has been mentioned, and that's talk with your insurance adjuster. At the very least you can find out what your liabilities are for various security measures, and possibly what measures will reduce your insurance rates.

    Start by looking at what a thief is going to see as they look at how to enter the property. You may find the TV series from a few years back "it takes a thief" (or something like that) helpful in looking at the entire place for security problems. The doors and windows may be barred, but is it possible to gain access through the floor, or ceiling? Even a good barred door may be a problem if it's sheltered in such a way that you can't see if someone is working on the lock.

    Part of that should also be looking at what you can do to improve deterrence. Signs, visible (if non-functional) alarm panels, even a steadily blinking light next to a sign labeled 'Alarm System' can be a deterrent.

    And finally look for ways to monitor the approaches to the property both front and back, and if the building is stand alone, all around the building. You may want to use PIR along with IR Lighting to capture movement around the building.

    If you are presuming that someone will break in after you've identified (and hopefully fixed) the issues from outside, then you're to the detect and defend internal options. High resolution cameras, covering the access points. Motion detection, door and window open sensors, glass break detectors, etc. These are intended to generate alerts and set up a means to capture what information you can about the thief. Tip, mark the door frame on either side of likely entrances with contrasting tape to form a crude (half foot or 20 cm increment) tape measure to give you a quick estimate of how tall someone passing by the entrance is.

    Obviously you will need to decide for yourself how critical it is to secure different parts of your store. High value gem dealers usually place their entire stock in a vault of some sort overnight. If you know what the reason is behind the break-ins in the area (paying for drugs being common) you may be able to protect high value items by making it easier to steel a few low value items that you are less concerned about loosing.

    Understand what the thief is working with. Unless you've been cased for a professional theft, in which case you're insurance carrier may have other suggestions for you, Most thefts are a snatch and grab variety, the thief is looking to get in, get something and get out. Be gone before the cops show up. If you know the cops will be there within 20 min, (talk with other businesses in the area that have experienced break-ins to find out if that estimate is even in the balpark) then you know how hard you have to make it for a thief to get at the valuables.

    Also set policies (and follow them) for how to deal with elements of the store that are critical for operating. Assume that a thief can get the cash register, all cash within the store, and possibly your computers in the store. Does someone have a spare cash register, and operating cash for the day that they can bring in at the start of the day if you need to get going while making repairs? Is there sufficient spare stock in an off-site storage to get up and running the next business day, or are you going to be waiting a week for your suppliers to restock? Is the customer information on your systems at work in a secure system? Do you have off site backups of your inventory and books? Have you a policy of depositing all cash over and above what you absolutely have to have for daily operations on a nightly basis?

    Your shop needs a door and to be inviting it needs to be airy and this is done by making it out of glass. But a glass door is easily shattered. A wooden door with two large glass panes separated by a wood bar in the middle is ALMOST as inviting but now the burglar either needs to remove the door, open it or climb in through ONE of the smashed panels. This is slower. He will still get in but be able to steal less in the same amount of time. This makes it less profitable.

    Shutter I mean one of those rollup "fences" that drop out ofthe celing, no idea what their english name is.

    One thing you could do for instance is leave your display window open but install a shutter inside the store itself as an additional barrier to overcome. Barely visible during the day, at night an extra barrier. Many people place them infront of doors but this just requires you to lift the shutter, then bust in the doors that tend to open inwards.

    Place an electrically lowered shutter BEHIND inwards opening doors, how do you open that one without a key? You can't push the doors in because the shutter is blocking that and you can't lift the shutter because the doors are in the way. Remember, theft prevention is like preventing being eaten by a lion, you don't need to be able to outrun the lion, you just need to outrun your neighbor.

    Hard is similar to slow of course in that you make the burglars work just that little bit harder. Just one more lock, just one more barrier to overcome. One thing we as consumers hate is those plastic wraps around products but they have a simple reason. They are very large meaning it is hard to conceal for shop lifters or at least conceal as many. And they are hard to open to make it hard to open them and take their contents. We know this works because well, we all bitch about how hard they are to open. Most of the large plastic containers are pure theft prevention and contain a fully serviciable selling/display package inside for shops that don't need to fear shoplifters.

    Do you NEED to store all your most valuable products in handy to carry containers right near the entrance to the warehouse? Or could you place your most expensive products on the highest shelf in the furthest corners? And lock up the ladder? And add some barbed wire to the shelves for those trying to climb it?
