Security vs. Emergency Alarms

Although they can go by different names, a security alarm is primarily used for anti-theft protection whereas an emergency alarm is used to protect against natural hazards like fires or harmful gasses.

Common Types of Security Alarms

Security alarms come in two common groups: monitored or unmonitored. Within these divisions, security vendors offer a variety of security alarm products.

Monitored security alarms contact emergency services or some form of a third-party professional when “tripped.” A monitored security system may be monitored by a security company, or by a customer themself. Typical monitored security systems include hub panels, motion detectors, entryway sensors, and keychains.

Unmonitored security alarms do not send out a signal to emergency services or a third-party professional when tripped. Unmonitored security alarms will use noise and lighting to warn homeowners of a possible invasion and scare off any unwanted visitors. Typical unmonitored security alarms include door wedge devices, window break sensors, entryway sensors, and keychains.

Common Types of Emergency Alarms

Emergency alarms come in three primary categories: fire/smoke alarms, carbon monoxide (CO) alarms, and water/flooding alarms.

Fire alarms, also called smoke alarms, sense changes in heat, the presence of fire, and the presence of smoke to warn homeowners and emergency service responders of a potential fire.

Carbon monoxide is an odorless, colorless, and invisible gas that is extremely harmful and potentially fatal to humans. Carbon monoxide detectors catch trace amounts of CO, warning homeowners and emergency service professionals of a dangerous leak.

Water damage from leaky pipes and flooding is very common and terribly expensive. Water/flooding alarms detect liquid leaks in weak points of a home, warning homeowners early to handle a potentially costly water leak.

Types of Home Security Systems

Traditional home security, sometimes called anti-theft security, is designed to keep intruders out of and away from your property. Anti-theft technology can be as simple as a sound-activated door jam, or it can be more intricate, such as a system of integrated motion detectors and home cameras.

Environmental security systems protect against naturally-occurring hazards: freezing temperatures, leaky pipes, gas leaks, and fire hazards. You may be familiar with one of the most common environmental security alarms on the market: the trusty fire alarm.

Generally speaking, smart home technology uses web-integrated systems that make your life a little bit easier. Smart home tech can open or close your garage door, lock the front door, and even change the thermostat from hundreds of miles away. Many contemporary home security systems use some variant of smart home technology, such as connecting your home’s alarm system to a mobile app.

No matter which home security system type you choose, you can be at ease, knowing that each one is designed to keep your home life safe and simple.

The Difference between Upfront Costs and Monthly Monitoring Prices

Although every home security vendor is unique, most vendors require new customers meet two price points in order to access full security services.

The first price point is known as upfront cost. Upfront costs cover the price of security hardware, software, and, sometimes, professional installation. This cost is typically a one-and-done—once paid, the price doesn’t have to be paid again.

The second price is known as monthly monitoring. Many security vendors actively monitor your home, standing at the ready in case an alarm, camera, or sensor is “tripped.” This price is typically subscription-based and paid per month.

Frequently Asked Questions (FAQ)

The most important places to monitor in your home are your entryways, meaning your doors and windows. First-time home security buyers should first secure these spaces with entryway detectors, motion detectors, security cameras, and some form of hub device.
Smoke alarms and carbon monoxide detectors are essential, life-saving devices for any home or apartment. First-time homeowners or renters should always have these devices utilized in and around the living space.
That’s a bit of a loaded question! As you may have guessed, the security needs of a 2,500 square foot home are very different from those of a 500 square foot apartment. When researching to buy a security system, ask yourself these questions: What am I trying to protect? How safe is my neighborhood? How large is my space? Do I already have security measures in my living space? Typically, a smaller space needs fewer alarm systems. A city apartment may only need a few fire alarms and one motion detector, while a suburban home may need four times the hardware to cover the larger space. When researching and purchasing your own security equipment, be sure you’re getting the appropriate equipment you need for the size of your space.
It is always a smart idea to have some form of protection. Folks on a lower budget would be wise to cover the essentials: smoke alarms, carbon monoxide detectors, and a basic form of anti-theft protection. If you have the means, a little more equipment can go a long way. Homeowners and renters can feel safer with 24/7 monitoring, doorbell cameras, and motion detectors. Want the height of luxury? Consider purchasing smart home technology to integrate your home and operate things like garage doors, locks, and the thermostat with the touch of a button.
The price of a home security system varies depending on the security vendor, the amount of hardware you’re purchasing, the size of the space you need protected, and the kind of functions you want your security system to perform. Speaking generally, you can find a great home security system for $100–$600 in upfront costs, and pay $15–$50 per month for monitoring.
