A Brief History Of Alarm Systems
It might sound like an elaborate, Looney Tunes-ish setup, but it was actually quite similar in many ways to modern alarms.
The first alarm systems were likely domesticated dogs (or even geese!) that would raise an alarm as soon as they noticed something was amiss.
Meanwhile, the first mechanical alarm was invented in the 1700s C.E. by an Englishman named Tildesley, who was obviously upset over the fact that someone apparently stole his first name. Tildesley fastened a set of chimes to a doorknob, so that any turning of the knob would cause a racket. It was effective at waking people up in the event of a break-in — provided the intruder used the door, of course.
About a century and a half later, a Bostonian named Augustus Russell Pope got a little more creative with his design, using electricity, magnets, and a bell attached to doors and windows. The idea was that an electrical current would pass through a circuit, and if that circuit were interrupted by someone opening the door or window, the resulting flow of electricity would hit the magnets, causing them to vibrate. This would then set off a hammer that would hit a brass bell.
It might sound like an elaborate, Looney Tunes-ish setup, but it was actually quite similar in many ways to modern alarms. Unfortunately for Pope, he didn't get much traction with his idea — but when he sold it to a shrewd marketer named Edwin Holmes, the system took off.
In 1867, a New Yorker named Edward Calahan conceived of a central monitoring station, which would alert all the houses in the area when one was being burgled. He used technology he'd already created when he invented the stock ticker to make his dream a reality, and Calahan would later go on to help form ADT, which is still one of the big names in home security today.
The 20th century saw new innovations, including motion detectors, video surveillance, and wireless systems. Staying one step ahead of criminals isn't easy, and trying to outsmart larcenous citizens is big business even today.
Of course, there's not a criminal in the world who would mess with a house that had a trained attack goose.
Pros And Cons Of A DIY Alarm System
The biggest advantage to a DIY alarm system is obvious: you won't be tied down to any pricey monthly contracts.
Most DIY systems are programmed to alert you when there's activity you should be aware of, which then allows you to decide how to proceed. You can have the alert forwarded to a neighbor who can check on your property, it can go to the cops, or you can just ignore it.
Professional alarm systems, on the other hand, have a central command center that performs that function for you. They'll investigate the activity, and if needed, contact the proper authorities.
The only other reason to consider a professional system is that they'll do all the work for you, including installation and maintenance.
This may seem like an unnecessary redundancy, but it could come in handy if you've been attacked and are incapacitated or otherwise unable to call the police. However, that's also a relatively unlikely scenario, and you may not be willing to pay exorbitant fees to protect against a long-shot occurrence.
Plus, one of the biggest advantages that any home security system offers is the ability to deter intruders, so just posting some cameras and a sign or two may be all you need to stay safe, even if the cameras aren't hooked up. It's a large part of what the pros would offer you, so it might make sense to just cut out the middleman.
The only other reason to consider a professional system is that they'll do all the work for you, including installation and maintenance. These systems don't usually require a lot of upkeep, so the maintenance shouldn't be overbearing, but it's up to you how much a hassle-free experience is worth.
At the end of the day, all that matters is that your family is safe, regardless of how you make that happen. And if that means you end up on a first-name basis with the cops that are always showing up after you forget your password, well, that's a small price to pay.
Other Ways to Keep Your Home Safe
By far the biggest thing you can do to help keep your home safe is get a dog. Studies have shown that over 95 percent of convicted criminals — the very people you really don't want in your home — would be scared away by the presence of a dog. Naturally, larger dogs are more intimidating, but even a small dog can be an effective deterrent if it's loud enough.

Even better, dogs can help improve your mood and your health, giving you lots of bang for your security buck. And, if you don't want to have to care for another member of the family, just getting a few "Beware of Dog" signs can be extremely effective.
You may also consider buying a gun. This isn't generally considered an advisable course of action, because you're more likely to use it on a loved one than a criminal and it's something that's only effective when the bad guys are already in your house, rather than keeping them out entirely.
Still, there are certainly situations where having a gun could save your life. It's just a matter of weighing risks — and it should go without saying that, if you have a gun, keep it somewhere safe.
Beyond that, a lot of the most effective strategies are just basic housekeeping. Don't let newspapers or fliers pile up by your door, and leave a light on when you're not home. You don't want to advertise when the house is a sitting target (and that means not announcing to the entire world when you're on vacation, so keep that info off Facebook and Instagram).
Staying safe doesn't have to be difficult. Just make smart choices, and above all, if you do decide to get a dog, send us some pics.
