The New York Times Recommends SimpliSafe Wireless Home Security Systems describes SimpliSafe alarms as

The New York Times Recommends SimpliSafe Wireless Security Systems

Many alarm companies have absolutely huge sneaky hidden fees. They advertise their alarms as being “from $99”, then they get you to sign a contract for over $1,000—and you can’t leave them for at least 3 years. But SimpliSafe alarms have no hidden charges.

We’re so confident you’ll love your SimpliSafe alarm that we’ll let you try it RISK-FREE with an incredible no-risk 60-day money back guarantee. SimpliSafe alarms are reliable, easy to use, have no annual contracts and no hidden costs.

SimpliSafe has you covered anywhere in the U.S.A with with the Verizon and T-Moble networks
Simplisafe is Safer and More Secure than most alarm systems

Safer and More Secure than 98.47% of alarm systems. Here's Why:

  • 24/7 Live Monitoring by expert specialists
  • We use COPS monitoring–named Best Monitoring 2014 by the Central Station Alarm Association. It's UL Listed, 5 Diamond Certified and FM Approved.
  • 100% Cellular: Faster than a Landline (and can't be cut!).
  • Smash-and-crash & Power Outage-Proof Protection.
  • Uniterrupted Protection: advanced fiber optics and multiple service providers ensure continuous coverage.

9 Things to Avoid When Choosing A Traditional Alarm Company

We listened to all the things you dislike about traditional burglar alarm companies... then fixed them.

Traditional Alarm Company SimpliSafe: a Better Way

Old wired technology. Traditional alarm companies want to put wires in your walls, because they know that ripping their wires out is hard and expensive.
SimpliSafe entry sensor State-of-the-art 100% wireless technology. We took the latest in micro-chip technology and developed smarter software to offer you a robust and reliable security system. With wireless, there are no holes in your walls.

Monitoring is $42.99 a month.

Ours is just $14.99 a month. SimpliSafe protects your home with COPS Monitoring - named BEST MONITORING in the Industry by the Central Station Alarm Association.

The moment you let them put a system into your home, you’re typically locked into a $1,547 contract with no way out.

No annual contracts! Our customers stay with us because of our excellent product quality and helpful customer support.

Auto-renewal clauses grab another $1,547 from you if you don’t cancel them within 90 days of the end of your three-year term. Forget to cancel? You’re legally trapped—there’s no way out.

SimpliSafe guarantee No hidden charges, no commitments, no sneaky tricks.

Many frustrated customers (just google “alarm system complaints” or “alarm contract complaints” and see for yourself).

Growing by word of mouth. See our Facebook fan page.

Uses a phone line to connect to the monitoring center. Burglars sometimes cut phone lines.

Cell tower Uses its built-in and independent cellular connection, which is 5-10 seconds faster, and is uncuttable. No phone line required.

Prices are kept high because there are so many middlemen and salespeople involved.

We don’t have expensive salespeople or middlemen. That’s how we can afford to keep our prices so low.

Installation typically costs between $99 and $500. You’ll need to take a day off of work, while the installer drills holes in your walls.

Set-up is easier than you could ever imagine. No tools needed, just adhesive pads. The unit actually talks to you while you’re setting it up. One of our customers purchased a second system for his daughter’s home and was “looking forward to the joy of installing it for her.” Watch our easy installation video to see what he means.
Does easy set-up mean the system is flimsy or less secure? No! Quite the opposite. No wires means there’s nothing for burglars to cut.

As soon as you sign up, there’s no going back: you cannot cancel even if you try.

We put our money where our mouth is: you can try us completely risk free, with three amazing guarantees.

SimpliSafe is not for you if...

1

You have a HUGE home: If your home is larger than 20,000 square feet (about the size of a football field)—or if it has more than 50 windows on the first floor—you would probably benefit from a system that can handle a huge number of sensors. Our advice would be to go to a traditional contract security company —and keep in mind the things we’ve warned you about.

2

You run a large commercial property such as a shopping mall—you would probably benefit from a system that has CCTV or security guards, in which case you should probably go to one of the traditional contract security companies—and keep in mind the things we’ve warned you about.

However, if you’re one of the 95% of people who don’t run a large commercial property, then SimpliSafe is probably the best choice for you. If you’re in any doubt, contact one of our security consultants at 1-888-957-4675 for free friendly advice.

Our competitor’s model sells for $56.00. Ours is $24.99. How do we sell the
highest quality sensors at half the price? No middlemen.

(dimensions: 3 x 2.25 in.)

Motion Sensor

(always on the lookout)

Full Room Coverage

Detects motion within 30 feet. The sensor has a “field of vision” of 90
degrees, giving you a full range of coverage when placed in a corner.

Flexible Install

The sensor is shaped to stand on a shelf, adhere to a wall, or fit in a
corner for maximum room coverage. Set the sensor to be active
only in “away” mode (so that you won’t trigger it when you’re at
home) or both “home” and “away” modes (for rooms that you want
covered with a motion sensor while you’re home).

Pet Friendly

Your dogs and cats under 50 lbs won’t trigger the alarm. We’ve
designed the sensor to be less sensitive to motion close to the ground.

Our competitor’s model sells for $93.50. Ours is $29.99. How do we sell the highest quality sensors at half the price? No middlemen.

SimpliSafe Works Even If the Keypad is Destroyed

Away mode:

When you go out,
this activates all
sensors.

Home mode:

When you come home,
this deactivates motion
detectors but protects
windows and doors

Keypad

(dimensions: 6.5 x 3.5 in.)

Problem: Most wireless alarm systems have an Achilles
heel—if a burglar smashes the keypad quickly enough, the
police don’t get alerted.

Solution: SimpliSafe took the “brains” out of the
Keypad and put them into a separate Base Station, which is
hidden somewhere in your home or office building. When an
alarm is triggered, the Keypad beeps to distract burglars.

Meanwhile, the Base Station stays quiet while it
alerts the monitoring service (which takes just a
few seconds). Once the alert has been safely sent,
the Base Station will blast its sirens.

Unlike other wireless security systems, if a SimpliSafe
keypad is smashed, the alarm continues to function.

Nest Thermostat

Works with Nest requires our
Interactive Monitoring Plan

Nest Learning Thermostat

The Nest Learning Thermostat programs itself, automatically saves energy when you’re away, and can be controlled using your phone. In independent studies, Nest Thermostat saved an average of 10-12% on heating bills and 15% on cooling bills. That means it can pay for itself in under two years.



SimpliSafe helps your Nest Thermostat know when you’re home or away. When you arm SimpliSafe to leave home, SimpliSafe tells Nest Thermosat, so Nest Thermostat knows it’s time to lower your energy use. When you come home and disarm SimpliSafe, Nest Thermostat knows you’re back and makes home cozy.

(dimensions: 3 x 1.25 in.)

Closed: Less than 2 in.
between the magnet and
the grooves of the
sensor.

Open: More than 2 in. between the magnet
and the grooves on the sensor.

Entry Sensors

(defend your windows and doors)

Easy to install on every type of door or window

The magnet goes on the door or window, and the sensor goes on the
frame (or vice versa). Magnet can be placed up to 2 inches from the
sensor, so sensors fit on all types of doors and windows. SimpliSafe
sensors come with the battery pre-installed and adhesive tape
pre-applied, making installation a snap.

Door Chime

When your system is OFF and a door or window opens, the
Base Station will sound a door-chime so you’ll know if
someone is entering.

How does it work?

The sensor detects whenever the magnet moves more than
two inches away from it- so it knows whenever the door or
window opens.

Our competitor’s model sells for $34.00. Ours is $14.99. How do we
sell the highest quality sensors at half the price? No middlemen.

The Base Station

(the brains of your system)

The base is Plug-and-Play: Plug it in and it will locate
and control all of your sensors, making SimpliSafe
the easiest security system in the world to install.

It’s also responsible for sending all your alarm signals
to our 24/7 alarm monitoring center. Your Base Station
will arrive equipped with the same cellular technology
that’s in your cellphone: Inside there is a SIM card that
gets activated when you subscribe to our alarm
monitoring service. If you’re subscribed to our
Interactive Monitoring Plan, it will also send you SMS
text Smart Alerts & Secret Alerts.

Pressing the panic button will instantly trigger the alarm and
our monitoring center will call to check if you’re okay. If you
don’t answer the phone or don’t give your “safe word” when
you answer, we’ll alert the police that you’re in danger.

Silent Panic

If you are a retail or business customer, we can program your
system to activate a “silent panic” feature for you, allowing
you to signal for help without alerting the intruder.

(dimensions: 3 x 1.6 in.)

Water Sensors

(stop damage from leaks & floods)

Your Water Sensor will trigger an audible alarm whenever it comes into
contact with water. Our alarm monitoring plans offer additional options to
get an phone call and SMS/email alert of any water alarms.

Why do I need this?

Flood damage is the most common Home Insurance claim, and it’s
certainly one of the most expensive. Place it near major plumbing to
detect breaks or in the attic to detect a leaky roof. Undetected floods and
leaks can lead to nasty mold infestations, ruined carpets, warped
wood floors, and damaged cabinetry and more.

Our competitor’s model sells for $44.99. Ours is $19.99. How do we sell the
highest quality sensors at half the price? No middlemen.

Freeze Sensors

(Prevents burst pipes)

The freeze sensor will trigger an alarm if the temperature in your
home falls below 41°. Our alarm monitoring plans also give you the
options to get:

  • A phone call and SMS/Email in the even of a freeze alarm.
  • Access to hourly readings of your home’s temperature in the Online
    Command Center.



Why do I need this?

If you have a vacation home, this sensor is worth it’s weight in gold if it
saves you from repairing expensive burst pipes. It’s also a perfect device
for protecting precious objects like instruments, paintings and plants in a
climate controlled room.

(height: 3 in.)

Glassbreak Sensor

(Detects the sound of smashing glass)

If a burglar breaks a window in order to enter your home,
this Glassbreak Sensor will detect the sound and trigger your
burglar alarm. Pair it with a Motion Detector in any rooms on
the first floor that have multiple windows.

Our competitor’s model sells for $78.99. Ours is $34.99. How do we
sell the highest quality sensors at half the price? No middlemen.

Smoke Detector

(firefighters straight to your door)

When a fire is quickening in your home every second
counts. SimpliSafe Smoke detectors are built with
photoelectric sensors for increased safety over Ionization
sensors. Photoelectric smoke detectors respond faster
(typically 30 minutes or more) to fire in its early,
smouldering stage before it breaks into flame, giving you
and your family more time to get up and out of your home.
Photoelectric sensors are also less likely to trigger
annoying false alarms.

Never worry about sleeping through a fire alarm. This
monitored smoke detector will sound its own internal siren
as well as trigger a full-blown security system alarm.

In addition alarm monitoring plans give you the
options to receive:

  • A call to alert you and firefighters sent to your
    home to ensure you and your family are safe.
  • SMS & Email Notifications automatically
    sent to your phone and to the phones of
    loved ones.
(height: 5in.)

Carbon Monoxide Detector

(sniff out deadly gas leaks)

Carbon Monoxide is a gas that you cannot see, smell or taste.
Deaths due to CO poisoning most often occur at night, when
everyone is sleeping. SimpliSafe’s CO detector uses
electrochemical sensing technology for highly accurate and early
detection of this invisible but deadly gas.

Dangerous levels of CO will trigger both the sensor’s internal
audible alarm and the siren in your SimpliSafe security system.

Our alarm monitoring plans give you the option to receive:

  • A call to alert you and emergency responders sent to
    your home to ensure you and your family are safe.
  • SMS & Email notifications automatically sent to your
    phone and to the phones of loved ones.

SimpliSafe guarantee

What is an “auto-renewal clause” anyway?

Most alarm companies have an automatic renewal clause in their monitoring and service contract (and use teeny tiny font). This means that your contract will be renewed for anywhere from 12 months to three years, unless you cancel by mail within 30 days before the end of your contract. Many of the nationwide and local alarm companies use this tactic. Cancelling early usually involves a penalty of 75% to 100% of the value of the contract.

Sneaky auto-renewal clause

SimpliSafe offers monthly alarm monitoring. There are no contracts to sign, so there’s no fear of getting tricked by fine print and hidden fees. You can cancel your SimpliSafe alarm monitoring anytime by simply giving us a call.
