  • 1. SimpliSafe – Best No-Contract Home Security Overall

    Editor's Rating
    SimpliSafe Home Security System

    An early leader in home contract-free home security, now on its third generation of equipment

    SimpliSafe is a top choice for those seeking good quality without a markup. The company builds mostly wireless security equipment, and you can own a starter set for $229 MSRP.

    What’s “simple” about SimpliSafe? The equipment is remarkably easy to set up. Also, the no-contract monitoring plans let you sidestep stress. For a while, the equipment was rather basic too, but SimpliSafe is now on its third generation. New SimpliSafe systems let you integrate Google Assistant or Alexa to control a doorbell camera, lights, and other connected equipment.

    Many people choose SimpliSafe for totally DIY home security. The base station siren works without paid service, and you’ll get entry alerts on the wireless PIN pad. You can add mobile alerts about system activity for $14.99/month.

    Going beyond DIY, the best SimpliSafe plan provides 24/7 professional monitoring. For $24.99/month you’ll get security backup from the award-winning COPS network of emergency dispatching centers. This SimpliSafe plan also adds the benefit of home automation with equipment from select brands.

    SimpliSafe Home Security Equipment

    Most SimpliSafe equipment is wire-free, which lets you accomplish setup without any tools. The only exception is the SimpliSafe Video Doorbell Pro; it connects to your old doorbell’s wiring, and you’ll need a Phillips head screwdriver for installation.

    Customers choose from various SimpliSafe starter kits. Prices start at $229 before discounts. Kits are designed for homes of different sizes; the bigger your home, the more sensors you’ll need for basic security. Some kits combine security sensors with environmental sensors (e.g., smoke detectors).

    A SimpliSafe Base Station is the heart of each system. This small cylindrical tower plugs into a wall and has 24 hours of battery backup. Its “Heartbeat” feature constantly checks your security system’s integrity, and a soft glowing light lets you know it’s working. Other features of the SimpliSafe Base Station are:

    • Voice prompts for set-up
    • 85-decibel siren
    • Can connect with 41 sensors
    • Cellular chip for optional pro monitoring
    • Tamper detection

    The Base Station works with a wireless keypad for entering your PIN. You can also arm your security system with a key fob, and with paid service, you can call upon a virtual personal assistant: “Hey Google, arm SimpliSafe to HOME.” SimpliSafe’s $24.99/month plan lets you add Google Assistant and Alexa to the system.

    As noted above, the base can monitor up to 41 devices. SimpliSafe makes sensors such as: 

    • Wireless keypads
    • Entry sensors
    • Glass break sensors
    • Indoor motion sensors
    • Indoor cameras
    • Video doorbells
    • Smoke detectors
    • Water leak sensors
    • Water freeze sensors 

    Additionally, several brands make smart home equipment that’s compatible with the SimpliSafe Base Station. Product choices include: 

    • Amazon Echo speakers
    • Google Home speakers
    • Nest Learning Thermostat
    • August Smart Lock Pro

    SimpliSafe lets you try any home security system risk-free for 60 days. If you decide to return the equipment, you can get a full refund and free return shipping.

    No-Contract Monitoring with SimpliSafe

    As you’ll read on our SimpliSafe pricing page, SimpliSafe gives three choices for no-contract home security monitoring:

    • Free do-it-yourself (DIY) monitoring without mobile alerts
    • Paid DIY monitoring with mobile alerts, $14.99/month
    • Paid pro monitoring with mobile alerts and remote control, $24.99/month

    Free DIY monitoring with SimpliSafe is rather limited; if you aren’t home, you won’t be alerted to trouble. At home, you can hear doorway entry chimes, the base station’s siren, and any additional sirens that you might connect.

    Paid DIY monitoring sends you mobile alerts if security is breached. You’ll receive info, but at $14.99/month the app isn’t enabled for remote control.

    For $24.99/month, professional monitoring activates your system’s cellular connection to COPS emergency dispatchers. It also gives you access to all SimpliSafe mobile app functions, including remote control over equipment connected to the Base Station.

  • 3. Ring Alarm - Best Alexa-Compatible No-Contract System

    Editor's Rating
    Ring Alarm (2nd Gen)

    Contract-free home security with the industry’s best Alexa integration Ring Alarm is a leader with smart doorbell cameras and other video surveillance solutions. Their equipment works beautifully with Amazon’s Alexa personal assistant, and a Ring hub can monitor much more than cameras; Z-Wave lights, locks, smart plugs, and other devices are compatible.

    Many customers choose Ring for totally DIY home security. No-contract paid monitoring is available too.

    Ring home security is best known for its doorbell cameras. Some need to be hardwired. Others are mainly battery powered and can be installed especially quickly. You can use a doorbell camera without a physical hub; the Ring mobile app works as a control center.

    Also featured at the Ring website are wireless indoor and outdoor security cameras. Special features are built-in sirens, floodlights, and two-way voice communication. 

    Ring Home Security Equipment

    As mentioned above, a Ring doorbell camera can work independently; no base station is needed. For small apartments with just one feasible entrance, a doorbell camera could be an adequate all-in-one home security system. However, the most robust DIY systems are built around Ring base stations.

    A Ring base station works with a wireless keypad. It can monitor a video doorbell, indoor and outdoor Ring cameras, your household lights, motion sensors, smoke alarms, and much more. The Ring website sells base stations in starter sets for homes of different sizes. The smallest set provides home security essentials for $199. Often Ring includes a free gadget, such as a smart light, to help promote its home automation options. (“Alexa, turn on my porch light.”)

    Surveillance cameras by Ring are cutting-edge and diverse. You can choose from hardwired and wire-free setups. Some Ring cameras can be solar-powered and have long-lasting rechargeable batteries; they can serve for years without maintenance. Especially powerful against prowlers is the $249 Floodlight Cam with bright LED bulbs, a 110-decibel siren, and two-way voice.

    Two-way voice helps make Ring cameras especially useful. This feature, of course, lets you holler at trespassers, but it’s also convenient for non-emergency communication within your household. The Stick Up Cam ($179) is a popular example. It works indoors and out, so with two-way voice family members can easily stay in touch from anywhere on your property. (If needed, a range extender can expand your Wi-Fi coverage.) Pressing a button on the camera or within the mobile app lets a person initiate interaction.

    As mentioned above, the Ring Alarm hub can monitor Z-Wave products from other brands. You can connect up to 100 gadgets such as:

    • Garage door tilt sensor by EcoLink – After driving away, or before sleeping at night, verify that you remembered to close your garage door
    • Smart deadbolt locks by Schlage – Enjoy keyless entry with a convenient keypad and mobile app
    • Plug-in smart outlets by GE – Let the Ring app automate your coffee pot, lamps, TV, and other household appliances

    Keep in mind that only Ring brand products can be professionally monitored. For instance, you could connect a third-party smoke alarm, but only a Ring smoke alarm can automatically alert the company’s emergency operators.

    You can try Ring Alarm equipment with a 30-day money-back guarantee.

    No Contract Monitoring with Ring

    A Ring doorbell or larger Ring security system can work without paid service; a free app for mobile or desktop can alert you to activity. The app lets you see live video and use the two-way voice function of Ring cameras.  

    To save the video, you’ll need a no-contract paid plan. One is for DIY monitoring, and the other adds pro monitoring:

    • Protect Basic adds video storage to DIY monitoring. It covers one device for $3/month or $30/year without a credit check. Videos are stored for up to 60 days each.
    • Protect Plus adds video storage and professional monitoring. It covers all Ring cameras and other Ring devices for $10/month or $100/year.

    Again, there is no contract or credit check for Ring Alarm. It’s a top brand for DIY video monitoring, and the hub works well with Alexa and third-party equipment. You can add professional monitoring anytime.
