High-end smart home systems with professional installation & professional monitoring Vivint is a longtime leader in smart home security. Their equipment can automate your home in many ways, and Vivint handles installation. A Vivint system can be your customized all-in-one solution to guard against crime, monitor for carbon monoxide, use electricity more efficiently, get voice control over your home, and more. Vivint can even guard your vehicles no matter where they’re parked! Professional monitoring is included with each smart home plan: A $39.99 monthly payment can help dispatch police, firefighters, or paramedics even when you can’t personally call for help.
Along with pro monitoring, customers get system control with the Vivint mobile app. The app lets you remotely view old and new surveillance footage, close your garage door from across town, adjust Z-Wave lights and locks, arm/disarm, and otherwise control the system as if you were home.
Google Home works with Vivint for remote control too. This voice-responsive app gives you hands-free power over connected equipment: Just tell Google when you want to arm your system and adjust lights, thermostats, and appliances. You can also summon Google Assistant to play music, read weather forecasts, play games, and otherwise enhance your day in countless little ways.
- Pro installation
- Seamless integration of all home systems
- Works with Google Assistant
- Supports Z-Wave for endless home automation options
- Pro monitoring can send police, firefighters, and paramedics
Vivint Smart Home Control
A Vivint security home system lets you control equipment in three ways:
- Home control with the Vivint Smart Hub, a computer with 7” touchscreen. The Smart Hub plugs into a standard outlet and has a 24-hour backup battery. In case of security breaches, it sounds a 100-decibel siren. The hub also has emergency call buttons and supports two-way talk for communicating with emergency operators.
- Voice control at home with a Google Home speaker
- Mobile control with the Vivint Smart Phone app for iOS and Android
Vivint Smart Home Equipment
Vivint Smart Hubs are Z-Wave compatible to give you endless add-on options. Listed here are some types of smart home devices that work with the Vivint hub. Some are made by Vivint, and others are third-party products.
- Doorbell Camera – This clever security device has a camera triggered by motion. The Vivint doorbell camera has night vision and lets you respond through the intercom as if you’re at home.
- Ping Camera – This indoor security camera has a motion trigger and gives the option to record continuously. It also has a video talk button for connecting with your mobile phone.
- Smart Locks – Vivint smart locks feature keypads with PINs for keyless entry and remote control. PIN use is trackable with the Vivint app.
- Garage Door Controller – This gadget can remotely sense and adjust the open/closed status of your garage door.
- Element Thermostat – This smart thermostat can adjust the temperature based on when you’re home and away. It’s programmable and responds to voice control.
In sum, Vivint is a top option for all-in-one smart home solutions. With one app you can monitor all home systems; there’s no need to use separate accounts for cameras, smart locks, lights, and so forth. Equipment is professionally installed too, which can save you lots of time if your home is large.
Any drawbacks? Vivint systems only work with a monthly payment for professional monitoring. If you’d prefer a system that works without fees, jump ahead to abode or Ring Alarm.
America’s oldest home security company, always with cutting-edge technologies
When ADT first provided security, they sent alerts with the latest technology: the telegraph. More than a century later, ADT leads the home security industry with smart wireless systems. ADT Pulse security systems are compatible with Alexa and Google Assistant for voice control, plus they have top-rated mobile apps for Apple and Android phones, tablets, and smartwatches. You can set up custom alerts in case sensors for intruders, smoke, or carbon monoxide are triggered. You can also remotely control your garage door, lights, locks, thermostats, and more.
ADT smart home customers start with professional monitoring. When your contract is up, you can choose another monitoring company without investing in a new system; ADT installs universal equipment.
- Pro installation
- Seamless integration of all home systems
- Works with Alexa and Google Assistant
- Supports Z-Wave
- Pro monitoring to send police, firefighters, and paramedics
ADT Smart Home Equipment
New wireless ADT systems use the Pulse iHub. This slim black box by Netgear looks similar to an Internet router, and it uses Z-Wave to connect smart home devices. Here’s a sampling of compatible equipment.
- Garage Door Controller – ADT’s mobile apps let you remotely check and adjust the open/closed status of your garage door.
- Smart Lights – ADT smart lights and bulbs let you control lights from anywhere you have mobile access. ADT Pulse can also change standard lamps into remote-controlled dimmers.
- Smart Locks – Use your smartphone as a house key. Smart locks in ADT security systems let you remotely lock and unlock your doors.
- Smart Plugs – ADT smart plugs give you the convenience of controlling appliances remotely.
- Smart Thermostat – Smart thermostats can help you stay comfortable and use home energy wisely. You can set up schedules, temperature alerts, and more.
- Doorbell Camera – The ADT Video Doorbell lets you talk with visitors even when you’re away, and you’ll be alerted to their presence even if they don’t ring the bell.
In sum, ADT Pulse can be your all-in-one solution for monitoring against crime, getting environmental alerts, and automating your home for energy savings and convenience. In many ways, Vivint and ADT Pulse have similar benefits and policies. It may come down to just making a price comparison. ADT Pulse prices are variable, as systems are customized for each home.
3. SimpliSafe – Best Google Assistant Compatible Home Security
SimpliSafe graces our best security lists consistently, and the list of best smart home security systems is no exception. Not only did SimpliSafe work with Google Assistant, but it also worked with Alexa, allowing us to arm our system in home or away mode with no hands. Of course, this option required that we buy the more expensive Interactive Plan. However, with 24/7 professional monitoring included as well as 30 days of cloud storage, $24.99 a month didn’t seem too steep, especially considering that some companies charge $60 for the monitoring alone. While we could’ve self-monitored and avoided all monthly fees, we wouldn’t get the push notifications or the smart home integrations without the top-tier Interactive plan, which makes the system truly smart.
Aside from working with two of the most popular voice assistants, SimpliSafe also works with Nest thermostats and August smart locks. This meant that we had our system arm in away mode whenever our doors were locked, meaning we’d left the house. At the same time, we had our thermostats lower down, saving us money on heating and cooling when we were away. Everything was controllable through both iOS and Android apps, both highly-rated on the Apple and Google Play stores, respectively. A relatively new security system, SimpliSafe was smart from the beginning, so we’re expecting more IoT integrations and voice commands in the future. And with a 60-day money-back guarantee, SimpliSafe is smart enough to let us return the system easily, if we had so pleased.
- Either DIY or professional installation for $79
- Works with Google Assistant, Alexa, August smart locks, and Nest thermostats
- 24/7 professional monitoring starting at $14.99 a month
- Notifications and smart home integrations for $24.99 a month
SimpliSafe Smart Home Control
We could control SimpliSafe not only with Google Assistant, but also with Alexa. Let’s start with Google Assistant and the commands we used successfully:
- Hey Google, arm security in home mode.
- Hey Google, arm security in away mode.
Alexa had even more commands in addition to the above, including:
- Alexa, ask SimpliSafe what’s shaking.
- Alexa, ask SimpliSafe for my current status.
- Alexa, ask SimpliSafe if I am protected.
- Alexa, ask SimpliSafe if my house is secure.
So while both Google Assistant and Alexa let us arm SimpliSafe in either home or away mode, Alexa was even more advanced, with a status-checking function. Still, for those in either ecosystem, SimpliSafe is a great option…that is, if you sign up for the Interactive plan.
4. Abode – Best DIY Smart Home Security
Do-it-yourself smart home security with optional pro monitoring Abode is a leading smart home company with contract-free options. Even without paid monitoring, your Abode siren and other security equipment will work! That’s not the case with systems by ADT Pulse and Vivint (above). Abode lets you enjoy the same sorts of features for safety and home automation as companies that require contracts – and they even go beyond ADT and Vivint by supporting Zigbee in addition to Z-Wave, Alexa and Google Assistant.
As an Abode security system owner, you’ll set up the equipment yourself without the need for special skills. The simplest option is an all-in-one plug-in system with optional add-ons. Thus if your home is small, you could accomplish setup within 30 minutes. However, you can add up to 160 sensors to a hub.
The free Abode mobile app lets you remotely control the system, plus it saves security footage short-term. You can add longer-term video storage ($8/month) or pro monitoring with video storage ($20/month) anytime.
- DIY installation
- Optional pro monitoring
- Supports Z-Wave and Zigbee
- Alexa and Google personal assistants
Abode Smart Home Equipment
Abode gives two choices for smart home hubs. Whichever you choose, it will work with Z-Wave and Zigbee. First, the iota security tower ($229) can be an all-in-one security solution: It has a wide-angle motion sensor, a high-def video camera with privacy shutter, a siren, two-way audio with VOIP, and other integrated features. It can also monitor up to 160 external sensors. Another option is the Gateway ($199), which has a siren and can monitor the same types of smart home equipment as iota. It can monitor up to 151 devices.
Here are examples of smart home sensors compatible with the base stations:
- Smart Speaker – Adding an Amazon Echo or Google Home speaker gives you voice control over the smart home system.
- Abode Cam – This indoor security camera can be set on a tabletop or attached to a wall with removable adhesive. Highlights are night vision, a motion sensor, two-way voice, and pre-alarm recording. If any part of your security system is tripped, the Cam will be activated.
- Smart Home Power Switch – Smart power switches let you remotely control the connected appliances such as lamps, fans, and toaster ovens.
- Smart Locks – Abode can support smart locks by Kwikset, Yale, and leading other brands. Enjoy keyless entry and control your locks from anywhere you have mobile access.
- Smart Thermostats – Add a Nest thermostat to your Abode system for convenient temperature control and energy savings.
That’s just a small sampling. The Abode security hub can also monitor video doorbells, outdoor security cameras, electronic window blinds, video screens, and other devices.
5. Ring Alarm – Best Alexa Compatible Home Security
Smart home systems with DIY installation and optional professional monitoring Ring first earned fame with smart video doorbells, and today they offer complete smart home systems. With Ring Alarm you can own a system with cutting-edge features for security, home automation, and environmental monitoring. Bundles are sold, plus you can build your own kit. Choose from an ever-growing list of Z-Wave devices by Ring, Nest, and other brands.
As an Amazon-owned brand, Ring has been developed to work seamlessly with Amazon Alexa. The voice commands feel natural, and you can ask Alexa to control a wide range of smart system functions. Examples are “Alexa, turn on the family room lights” and “Alexa, show the latest activity from the patio.” Additionally, with Ring you can use Google Home speakers and ask Siri for help.
Monthly payment isn’t required to keep a Ring Alarm system running. For instance, for free you can get text alerts and remotely view live camera footage. However, payment of $2.99 and up per month lets you save footage from Ring doorbells and other security cameras.
For under $10/month you can save video and get professional 24/7 monitoring of alerts as well.
- DIY installation
- No contract required for monitoring
- Supports Z-Wave
- Works with Alexa, Google Assistant, and Siri
Ring Alarm Smart Home Equipment
The Ring base station can monitor up to 100 devices. You can choose the elements individually or get a Ring Alarm starter set ($199 and up). Here are some popular add-ons:
- Stick Up Cam – This weatherproof camera is easily set up anywhere on your property to guard the vicinity and allow two-way talk. It’s handy for everyday communication with family members as well as communicating with Ring Alarm operators.
- Garage Door Tilt Sensor – The EcoLink garage door sensor can indicate whether your garage door is shut. The Ring mobile app lets you remotely open and close the door.
- Smart Locks – Schlage smart locks work with Ring to allow keyless entry. You can set PINs and track their use with a mobile app.
- Smart Outlets – The Ring app can connect with General Electric smart plugs to automate your household appliances.
- Smart Thermostats – Ring works with Nest thermostats for smart energy management and the convenience of setting the temperature by voice.
All in all, Ring is a flexible smart home solution with a straightforward DIY setup and easy control with Alexa. Paid video storage is affordable at just $2.99/month for one camera, and for $100/year you can get pro monitoring for all Ring equipment.
The Questions We Get The Most
Who has the best home security system?
The best home security system is SimpliSafe, as it offers self-monitoring, professional monitoring, DIY or professional installation, plus smart home integrations with Alexa, Google Assistant, Nest thermostats and August smart locks.
Is Nest better than ADT?
No, Nest is not better than ADT; rather, ADT is better than Nest, albeit more expensive month-to-month. While Nest has had multiple security and surveillance issues, ADT has been in businesses for over 140 years without incident. ADT also offers professional installation, while Nest is all DIY. However, those that don’t want to commit to a long-term contract should choose a monthly plan from Nest, as all ADT plans require a three-year commitment.
What is the home security system with the best value?
The best home security system with the best value is SimpliSafe. You can avoid paying any monthly fee whatsoever with SimpliSafe, if you’re okay with having a local alarm system only. However, if you want professional monitoring, cellular backup, remote control, notifications and smart platform integrations, the price is only $24.99 a month with no long-term commitment.
Is Ring or SimpliSafe better?
We prefer SimpliSafe over Ring Alarm, although both systems are two of the best. Although Ring Alarm is cheaper with a wider selection of cameras and video doorbells, SimpliSafe offers a professional installation option for $79, plus integrations with Nest thermostats and August smart locks. Ring works with the less popular Dome, Ecolink, GE, Leviton and First Alert IoT devices. SimpliSafe also has better iOS and Android apps and a three-year warranty as opposed to one-year with Ring. Similarly, SimpliSafe offers a 60-day money back guarantee with shipping covered, while Ring has a 30-day return policy which does not reimburse for the cost of shipping.
