Detailed List of the Best Affordable Home Security Systems

  • 1. SimpliSafe - Best No Monthly Fee Home Security

    Editor's Rating
    SimpliSafe Home Security System

    SimpliSafe helps make security cheap with optional contracts. Many other security companies require 12-month to 48-month contracts, but with SimpliSafe’s contracts, everything is month-to-month.

    Why would you want a contract? Two benefits are:

    • Contracts let you pay for expensive security systems over time.
    • Contracts can provide 24/7 professional monitoring. In other words, the company will call 911 in case of an emergency.

    With SimpliSafe though, home security systems are cheap (about $200 and up), so people can pay all at once. Professional monitoring is optional and starts at $14.99 per month. Without professional monitoring, you can still receive free text alerts from the system in case of an emergency.

    What We Like
    • Affordable security equipment
    • Portable
    • DIY installation
    • Free text alerts
    • Optional monthly contract
    What We Don’t Like
    • No outdoor cameras
    • Proprietary equipment

    How SimpliSafe is the Best No Monthly Fee Home Security

    SimpliSafe lets you completely avoid monthly fees or choose cheap monitoring month-to-month. Besides that, with SimpliSafe you can save on equipment and installation.

    Equipment by SimpliSafe is cheap, user-friendly, and tamperproof. It’s affordable partly because SimpliSafe manufactures the equipment themselves. For comparison, most other security companies buy control panels and sensors from third parties such as Honeywell and then resell at a markup.

    As for installation, with SimpliSafe there’s no cost except your own labor. All equipment is wire-free for simple setup in about 30 minutes. These affordable security systems are also easy to re-install when you relocate.

    About SimpliSafe Equipment

    A basic SimpliSafe set costs about $200. You might find a deal that includes a free video camera, which sells for $99 separately. Equipment is available in black or white to blend with your decor.

    The most affordable home security system includes:

    • A base station
    • Two entry sensors
    • One motion sensor
    • One SimpliCam (limited time only)
    • Keypad
    • Remote control

    The base station is a small tower with a loud alarm. It plugs into a wall outlet and has a battery backup. A soft blue light indicates that it’s working – and if someone tampers with the system, police can be notified automatically with the cheapest paid monitoring deal, $14.99/month.

    Entry sensors can be set to chime when motion is detected. In case you’re out of earshot, alerts about entry and other security events can be sent to your mobile phone for free.

    As for the wireless camera, SimpliCam captures video with high-definition footage. The device is triggered by motion and can send alerts to your mobile device.

    You can expand the basic set with additional entry/motion detectors and SimpliCams. Also, a SimpliSafe system can monitor the environment with smoke, temperature, and water sensors.

    In sum, SimpliSafe provides affordable home security with savings on equipment, installation, and monitoring. A possible downside, however, is that the SimpliSafe camera isn’t weatherproof.

  • 2. Cove - Most Affordable System with Professional Monitoring

    Editor's Rating
    Cove Smart Home Security

    All of Cove’s systems come with one of two plans, Basic or Plus, but both include 24/7 professional monitoring and cellular backup, which starts at $14.99 a month. This is a very low price; the only lower price we’ve seen is from Ring, which offers the same features for $10 a month. Cove’s Plus plan throws in even more features, like Alexa and Google Assistant integrations plus remote control, for $24.99 a month. Even though it’s $10 more than the Basic plan, we think it’s worth it to be able to arm and disarm our system remotely and control it with our voices.

    What We Like
    • Professional monitoring starts at $14.99 a month
    • Cellular backup from AT&T LTE
    • Alexa and Google integrations available
    • Easy and free DIY installation
    What We Don’t Like
    • No outdoor or Cove-branded cameras
    • No option to self-monitor
    • Smart home integrations start at $24.99 a month
    • Remote control starts at $24.99 a month

    Why Cove is the Best Affordable System for Professional Monitoring

    We’ve already told you about Cove’s low prices for 24/7 professional monitoring, but those weren’t the only costs that struck our fancy. Their equipment is also priced at a low rate, and we even got a YI indoor camera, completely free. You can learn more about the exact prices on our page on Cove costs, but keep in mind that their most expensive component, the Touch Panel, still comes in at less than $100. This makes Cove a particularly affordable option, especially for those that live in small homes or apartments. You can buy as much, or as little, equipment as you need.

    About Cove Equipment

    Equipment-wise, Cove offers the following:

    • Touch Alarm Panel
    • Door, motion, window, glass break, smoke, heat, freeze, flood, and CO detectors
    • YI indoor camera
    • Medical button
    • Key remote.

    While Cove doesn’t make any of their own cameras, we were happy that they gave us an indoor camera from YI, completely free. And even if you want more cameras, they would have just been $29.50 each, a strikingly low price. Learn more about how the camera and system worked in our Cove review.

    Prices for ADT equipment and monitoring (required) depend on your home’s layout. You need to talk with an agent for a price quote, but ADT is best in terms of their money-back guarantee: It’s effective for six months and provides for a full refund of expenses.

Tips About Affordable Home Security Systems

Security savings take different forms. How do you get a trustworthy system for a great price?

Cheap Security Installation

Installation can be an easy way to save. Often there’s no need to pay a professional electrician. You can set up a wireless system yourself in an hour or less:

  • Some cheap security systems are plug-and-play. An example above is Abode’s iota Smart Home Tower.
  • Typical DIY installation takes about 30-60 minutes for setup without tools. Sensors can attach to surfaces with removable adhesive, yet are tamper-proof too. Favorite options come from SimpliSafe, Frontpoint, and Abode.

If you’re set on pro installation, ADT is a top recommendation with a maximum charge of $99. With other companies above, there’s no charge for installation because you do it yourself.

Cheap Security Equipment

Equipment prices from the leading companies start around $100. For instance, with Frontpoint, you can get a basic set for just $99.

When choosing a home security system, remember to consider whether it’s proprietary or can be monitored by another company. If it’s proprietary, you’ll need to buy new equipment if you switch monitoring companies.

Another tip: Find out whether you’ll own the system after a monitoring contract is fulfilled. Some companies reclaim the equipment.

Save On Security Monitoring

Monitoring for emergencies is the third main area for savings.

When you own security equipment from select brands, you can self-monitor it for free. For example, SimpliSafe systems send text alerts when systems are breached.

However, generally, the best home security comes with professional monitoring. Pro monitoring ensures that someone will call 911 in case of an apparent threat to you, your loved ones, or property. This can give you extra peace of mind.

When you get a home security quote, make sure that it fits your situation. Some companies advertise low rates that actually only apply for landline signaling. Cellular signaling is less vulnerable to tampering.

Ask About Insurance Discounts

Home security can help you save on insurance.

If you have homeowner insurance or renter insurance, tell the provider about your home security system and flood/fire protection. Many insurance companies give discounts of 10 to 20 percent when you help protect your home.
