    Just because you’ve got a big house doesn’t mean you need a big home security bill. Cove’s equipment is cheaper than comparable wireless components from many home security providers we’ve reviewed, so even homeowners living in the proverbial mansion should be able to secure it without having to take out a second mortgage on cameras and sensors.

    While you won’t get smart home automation like you would with an alternative like ADT or Vivint, Cove’s security sensors run the gamut — from smoke, flood, and CO, to burglary and intrusion. And now that Cove is partnering with RapidSOS, emergency services should (theoretically) respond to alerts faster.

    • Simple DIY Installation
    • No Contracts, Month-to-Month Service
    • Smartphone Controls
    • Touch-screen Control Panel
    • 1080p HD Indoor and Outdoor Cameras
    • Alexa and Google Assistant Compatible
    • Low-Cost Monitoring
    • Lifetime Warranty Option

    • App Experience Could Be Improved
    • Limited Home Automation Features
    • No Self-Monitoring Option

    Homeowners want to feel secure throughout their homes. This can be a challenge if you live in a bigger place. (We’re talking anything above 2,500 sq. ft.) There’s more entry points and more space you can’t be monitoring all the time. Which typically translates into complicated home alarm systems with fees to match. Not so with Cove.

    In our hands-on Cove wireless equipment review, we figured you could rig a 3,000 sq. ft. home for around $350. (Even a massive home with 12 window sensors, three door sensors, and a doorbell cam came out to under $450.) Add a Cove Plus monitoring plan for $24.99 monthly — which gives you round-the-clock emergency assistance backed by RapidSOS and live video feeds at 1080p HD quality — and you can rig the whole palace for under $500.

    Of course, if you’re looking for smart home automations to shave money off your electricity bill (and possibly save you money on your home insurance premium), Cove isn’t going to help there. Ditto for smart door locks. Cove doesn’t carry them.

    However, if you want professionally monitored, top-of-the-line wireless security equipment you can install yourself in under a half hour, Cove might do the trick. For more on Cove’s plans and features, check out our complete Cove pricing guide.

Features of Home Security Systems for Large Homes

Some of the most important features of home security systems for large homes includes customized home security, home automation and surveillance. Customized home security secures your entire home no matter how large. Here are some of the other popular features of home security systems for large homes. And for more tips and benefits, visit our in-depth security system buyers guide.

Arm/Disarm Security

Control panel, mobile apps, remote control — there are several different methods of arming and disarming your security system. If you have a large home and desire peace of mind, then you’ll be glad to know you can control your system from virtually anywhere. Most security systems for big homes offer mobile access. That’s total home protection, from the convenience of your smartphone.

Door Locks

Door Locks is another popular feature among those who own large homes. And not just door locks, but smart door locks. This option automates your entryway with an electronic locking mechanism. And it’s stacked with benefits. Get keyless entry, remote locking and unlocking, and many smart locks even let you hand out virtual keys to friends, family, and service providers.

Home Automation

Here’s another top home security feature that’s especially helpful in large homes. Home Automation puts smart home features — features like smart lighting, door locks, thermostats, garage door controls, security cameras, and more — right on your mobile device. Now you can control, adjust, monitor, and do just about everything from your smartphone. Smart home automation makes your life just a little bit easier.

Remote Access

Do you own a large home? If so, Remote Access allows you to hop on a mobile app, from anywhere in the world, to access and monitor your home security system. If your home is outfitted with automation features, you can even do things like remotely lock and unlock doors, open and close the garage door, turn on the AC, and more.

Doorbell Cameras

A smart doorbell camera is a wise investment for those with large homes. If a visitor comes a-knockin’ and you’re on the other side of your house, this feature allows you to tap into your doorbell video from your smartphone. Some even offer two-way talk — a unique feature that enables you to speak and hear visitors. Welcome to smart home security.

Expandable

Don’t limit yourself when it comes to home security, especially if you live in a big house. It’s important to choose a home security system that is expandable. An expandable system syncs with third-party equipment and devices. Security cameras, motion detectors, smart home automation features — all of these work together to deliver a well-rounded security system.

Motion Detection

It’s no secret that large homes require more attention to detail. This holds true for home security monitoring, too. Strategically mount motion detectors throughout your home. The moment they detect motion, the alarm will sound and alerts are sent. Motion detection is particularly important in rooms with high-value items like art, jewelry, or a gun collection.

Entry Sensors

Entry Sensors are a standard offering with every security system. The magnetic sensors are mounted on doors and windows. When the magnets separate, the system signals a security breach by sounding the alarm and sending alerts. If you live in a large home, purchase a package with enough sensors to cover your multiple entry points. Or purchase additional sensors sold separately.

Glass Break Sensors

Large homes tend to have plenty of entry points. And many criminals like to bash windows and make off with your belongings. Stop them in their tracks with Glass Break Sensors. These sensors use microphone technology to detect the distinct sound frequency of glass breaking. When triggered, the alarm sounds and alerts are sent. Go with glass break sensors to protect your property.
