Our Take on ADT Home Security

Superlative: Best Overall

Recommended Package: We recommend the ADT Complete Package. For $59.99 a month, you can receive professional monitoring, mobile app integration, video surveillance, and smart home automation features.

ADT is one of the most comprehensive options on this list. The company offers professional and self-monitoring options for both wireless and landline security equipment. Landline equipment is an excellent option for business owners or anyone looking for higher quality video and is an uncommon offering nowadays. The company also provides plenty of smart-home options and a user-friendly mobile app to control your system with.

SimpliSafe not only offers comprehensive equipment options, but its easy-to-install packages made it our No. 2 choice in home security systems overall. All of its systems are easy to transport and come with a three-year warranty. The company does offer limited smart-home automation options when compared with ADT or Vivint, but customers avoid the long-term contracts that come with those companies.

3. Abode: Best for Customization

Founded in 2014, Abode is relatively new to the home security industry. However, it provides a wide selection of home security devices and monthly monitoring packages that don’t require a long-term contract. We find Abode the best for customization due to its Build My System option. This option involves working with an Abode representative to create the perfect security package for protecting your home.

Abode Packages & Pricing

Abode prices range from $342–$445 for packages and $0.20–$0.66 per day for professional monitoring.

If you are concerned about getting each of your security needs fulfilled, Abode is a great choice for you. Its Build My System option starts with a questionnaire, which recommends devices based on device preferences and the area you’re protecting.

Many other home security companies provide custom package deals, but Abode’s monitoring plans are affordable and flexible. Products can be used for professional or self-monitoring, and its professional monitoring is charged per day rather than per month.

Vivint prices range between $599.00 and $1,789.92 for packages and $29.99–$49.99 per month for professional monitoring.

Our Take on Vivint Home Security

  • Superlative: Best for Smart Home Integration

This package includes the home security essentials, plus an indoor, outdoor, and doorbell camera. If smart-home automation is more important to you, the Smart Home Control Package may be the best option.

Vivint is a great choice for anyone wanting smart-home automation and a professional installation experience. Customers are guaranteed their system will work, because Vivint does not allow DIY installation of its systems. Vivint offers more smart-home products than companies like ADT or Frontpoint, with integrating capability for third-party platforms like Google Home and Nest.

Our Take on Frontpoint Home Security

If you value control and a user-friendly experience, Frontpoint is a great choice for you. Though other home security systems use smartphone applications, we found Frontpoint’s mobile app to be the most impressive. The app arms and disarms your system no matter where you are, and it also allows you to view live or recorded video. Notifications and alerts can be received over email, text, and push notification. Customers are even able to control locks, thermostats, and lights through the app.

6. Alder: Best for Medical Alerts

Alder Home Security is a basic home security system and ideal for those who are new to home security systems. Alder helps you create a customized package based on your needs and the size of your home. Alder’s medical alert pendants and buttons paired with its professional monitoring make it an excellent choice for those concerned about medical emergencies.

Alder Packages and Pricing

Alder provides only custom packages, unlike most home security companies. It offers a touchscreen panel, indoor/outdoor cameras, door/window sensors, motion detectors, medical alert buttons, doorbell cameras, and other items. You can expect to receive two-way audio with Alder’s indoor cameras.

Alder’s custom package pricing will vary depending on the items you choose. However, professional monitoring fees start at $39.99 per month.

Our Take on Alder Home Security

Alder features many industry-standard home security options like smart-home automation with Amazon Alexa and easy-to-install equipment. Though Alder requires a three-to-five-year contract between, the company provides a 30-day trial period and a one-year warranty on its equipment. We also found Alder’s commitment to life safety a great perk of the company. It adds another layer of security to your system for flooding, fires, and medical emergencies.

If you want to learn about how Alder helps with more than just break-ins, check out our review on Alder.

7. Canary: Best for Two-Way Audio

Canary Home Security is a great option for those looking for top-tier technology in their security package. Each of Canary’s packages comes with a video camera that alerts you to activity inside the home, records video, and automatically adjusts its security mode based on home activity. Canary can also assist with smart-home integration to help monitor temperature and air quality.

Canary Packages & Pricing

Feature Canary View Canary Pro Canary Flex
Feature Canary View Canary Pro Canary Flex
Cost $99 $169 $199
Motion Detection
Night Vision
90 Decibel Siren
Temperature, humidity, and air monitoring
Camera HD Camera with 1080p image sensor HD Camera with 1080p image sensor HD Camera with 1080p image sensor
Field of View 147-degree wide-angle lens 147-degree wide-angle lens 116-degree wide-angle lens

Canary provides three package options. Its packages combine the cameras and services listed above. Here are the packages customer pick from:

  • Starter Pack: Canary Pro (1) and Canary Flex (1)
  • Total Home Pack: Canary Pro (1) and Canary Flex (2)
  • Outdoor Security Pack: Canary Flex (2) and Secure Mount (1)

Canary’s prices include camera costs, ranging from $99 to $199. Customers then choose from Canary’s three service plans, which run from $9.99 to $14.99 per month.

Canary also provides an affordable payment model. When you receive Canary’s equipment you technically rent the equipment for a monthly fee rather than pay for it all at once.

Our Take on Canary Home Security

  • Superlative: Best for Two-Way Audio
  • Recommended Package: We suggest Canary’s Starter Pack, which includes intelligent cameras that feature motion detection, night vision, and a built-in siren. Canary’s Premium Service plan will add two-way audio to this package.

We recommend Canary for tech-minded home security consumers. We find the HD two-way Canary Talk feature paired with live video on Canary’s mobile app particularly impressive. It lets you communicate remotely by speaking into the Canary app on your mobile device and having the audio play out of your Canary device’s speaker.

Canary does not offer separate motion sensors in its packages. Its system uses “computer vision” to register changes in on-screen pixels, registering pixel changes as motion. Canary’s computer vision algorithms then try to filter out repetitive motion from things like ceiling fans, or background motion like lights and shadows to provide you with intelligent notifications.

Canary is also perfect for outdoor monitoring with night vision in all of its packages.

If you want more details and specifications on Canary’s equipment then get more information from our review.
