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.

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.


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.
