Some tips I remember from an interview with a burglar a few years ago (can't find a link now): Make it difficult for someone to conceal themselves while breaking in. If a burglar has to be in full view of the neighbors while he breaks in, it increases the risk of him getting caught. Avoid tall/thick shrubs around your windows and doors. Avoid privacy ...

Don't have anything valuable. Or at least, don't appear to. Look like you care about upkeep and security. You don't have to outrun the bear, etc. Secure your air conditioners if they're in-window. That's so easy to do. Avoid doors which have glass near the doorknob. I watched This Old House putting in a beautiful glass door in a crappy part of Boston and ...

Any lock can be opened. The questions are: How long will it take? How much skill is required? What tools are needed? Depending on the particular deadbolt, it will be somewhere between trivial and moderately difficult. At some point, anyone who wants to get in will just move to the windows or other weak points.

If your lock is a just a simple pin tumbler then its vulnerable to bumping. There are some pin tumbler locks that say they protect against bumping, but in practice it might be a little more difficult, but still very vulnerable. In fact the only deadbolt lock that I know of that isn't vulnerable to bumping, rakeing or other simple attacks. Is the ...

In general, a professional is going to be able to open anything you have, because that's what they do all day. The reality though is that with the exception of high security locks like Medeco, it doesn't even take a professional to open them. But you ask about a deadlock, so let me provide some background... A deadbolt is more about resisting kicking open ...

I ordered a set of bump-keys and tried my doors. It was $15 (with shipping). What's particularly interesting (at least to me) is that the method of 'bumping' open a lock has been around since the 1930s. It just wasn't well known by the general population until it was picked up by some TV shows/News stations in the 2000s. Anyway - read the countermeasures ...

The lock in the knob can be set to be locked when the door is closed. In other words, you do not have to do anything extra to lock the door, just pull it closed. This can be good or bad depending on how you look at it (it can be easy to lock yourself out this way). The dead bolt on the other hand always requires an extra step to lock the door (put the key ...

Forget securing the door, and install a security system with a motion sensor. Put labels up outside saying there is a security system (some people only put labels up, and don't have a real system). Even if you have a door with a locking mechanism, if someone manages to defeat it (eg, kicks it open) or you forget to lock it, you still have the alarm go off. ...

There is a product called Window Security Film which is a thin (a couple mm) film that adheres to the window and makes it exceptionally difficult for someone to break. Many lock smiths/security companies can install it. Here's a video of it in action: http://www.youtube.com/watch?v=vYdVK3BqPfk This is a duplicate of my answer from this question.

They make locks for the doors that only unlock when the collar worn by the dog is within a few feet. There's this product: http://www.petdoors.com/cat-mate-electronic-cat-doors.html . It's a cat door, but it works on the same principle. Also, most of these you can set to 'allow onyl departures' or 'only arrivals' as well. - might not be applicable to ...

Buy a crappy, broken laptop from a flea market for $5. Leave it in the entrance hall. Leave the front door unlocked. Most intruders just want to grab something valuable and get the heck out. The faster you can give them something that they think is (a) portable and (b) valuable, the faster they will leave.

You could add some inexpensive window break alarms to supplement your current alarm system.

What I have yet to find a solid answer on is what is typically run to the keypads. Do I run cat5/6, or use the same security wire (or both)? I recommend running 22/4 and cat5e from the security panel to the keypads. That provides lots of options. Once I run the wires to each window, where do I leave the wire? I recommend leaving a coil of wire ...

Looks like a wireless garage door keypad.

Note, I'm not anywhere near an alarm professional, however I have installed a couple systems before and have just recently been researching again as I prepare to move into a new house where I'd like to install an alarm. Keypads You'll want a keypad anywhere you normally enter/exit the house, such as by the garage door or back door. As @bib points out, you ...

IR motion sensors can be thought of as a low quality camera with only one color, IR. They are constantly comparing the IR levels across a grid to see when there is a quick change in IR levels. When you look at the housing of a sensor, you can see this grid, and unlike that of a digital camera with mega-pixels, these sensors only have a dozen or so ...

It's called a spanner slotted (or slotted spanner) head. Useful site here. Hard to find in the UK, why the owner used one I cannot imagine. Screwfix doesn't have them. This site may do, although it is international. You'll need to figure out the correct size before you order. Alternatively get a real cheap flat-head screwdriver the right width and file ...

I've used something similar on my front door for about 4 years now (4xAA instead of a 9V) and it's great not having to carry keys everywhere. On average, I change the batteries about every 12-18 months. I guess it all depends on how often you use it and how worried you are about getting locked out. Personally I don't bother testing the batteries because ...

I agree with Jeff and Mike's answers, but you also have to make sure the lock was installed correctly. When I bought my house and changed the locks, I found out that the strike plates installed (deadbolt and doorknob) on the front door were only screwed into the trim with 1/4" screws. It wouldn't have taken much force at all to rip them right out. (My guess ...

My guess is that it is a security keypad. The DNS on the cover could be from D.N. Security Services, Inc. a company from Northern California that was acquired by Universal Services of America in 2009: http://www.universalpro.com/news2.html.

For this to happen there must be some voltage to the light socket. It may not be noticeable with a standard incandescent bulb because it apparently is not the full voltage and current. If you are comfortable in what you are doing, you could measure the voltage across the two wires and ground to see what you get. Incorrect wiring could be the problem, such as ...

I like the buried chain idea. In fact, you don't even need to use cinder blocks. They make 'earth screws' which are large auger-looking thing that you literally screw into the earth. Typically used as playset tie-downs or party-tent tie downs. Alternatively, maybe attach a bar to one of the fence posts. I'm thinking one of the stainless hand-bars you'd ...

Presuming you're talking about passive infrared or PIR detectors, you do not want them pointing at your windows. They detect changes in the ambient temperature in the field of view, and pointing at windows causes them several problems: heating registers are often located under windows, so when your heating system turns on and off, the temperature will ...

Chances are good that there is only one cable coming into that light, and it is switched by the interior switch. If this is the case, as I suspect, you cannot draw power for your cam without the light being on. you will need to find a continuously powered set of wires or run a new set to your cam.

As Shirlock mentioned, the switched lamp is a problem ... however, there's a possible solution: replace the light with a fixture that'll switch at dusk. leave the switched turned on. You could bypass the switch, but then it's more inconvenient if you need to do work on the circuit. You can get covers that'll screw on over the faceplate so someone won't ...

As for expanding the hole, I am still confident this post will answer your question. Regarding the Schlage deadbolts, these are not great deadbolts. If you really want high security, you need to look at Mult-T-Lock or Medeco. These are far more secure for a number of reasons. First, they are made of much harder metals - if you feel them compared to ...

You may want to consider keyless entry systems. The cards can be programed to allow or deny access. Once a conventional key is issued it will work until the lock is changed. A keyless system can disable individual cards in the event of loss or theft. The initial cost may seem high but if you are rekeying locks and making 48 copies a couple times a year it ...

If your concern is while you are away at night, you can also set up lights to go on/off using a Lamp/Appliance timer outlet: It has a security feature that turns the lights/TV/radio on/off randomly ("a random setting option, which can turn lights on at unpredictable times to make your home appear occupied when it isn't").

When I was growing up we had a simple system on the dog door into our garage, it was 1/4" thick steel plate that was slightly larger than the opening and a set of rails on two sides and the bottom of the door. When we were away and wanted to secure the door, we simply slid the plate into the slides with the handle that was on the back, and flipped a hasp ...
