Best Smart Door Locks for Home Security

0/0

Smart door locks combine the functionality of traditional deadbolts with modern technology. They offer a range of keyless entry options such as keypads, key fobs and remote access systems. Plus, some brands have advanced features like biometrics, proximity unlocking and NFC technology.

Biometric smart locks provide instant access using fingerprint scanners, 3D facial recognition or palm scanning. Proximity locks allow you to open the door automatically as you approach. Digital and NFC locks feature backlit keypads and physical key fobs that grant entry with a tap of your smart phone.

Tip: If you are replacing an old lock, measure your door’s backset, bore hole diameter, thickness and deadbolt clearance to save time and prevent installation issues.

Modern smart locks improve home security by connecting to other devices. For example, you can program your lights to come on when you unlock the door. Or if your smart home security network includes cameras, you can see who’s at the door. There are different connectivity options that provide everything from remote access to real-time monitoring.

Each connectivity type comes with unique features and benefits. For example, Wi-Fi is compatible with virtually every device. Short distance wireless networks like Bluetooth, Z-Wave and Matter Over Thread provide localized reliability.

Wi-Fi smart locks connect directly to your home network. Once they’re linked to your router, they have unlimited range. You can lock and unlock your doors from anywhere without needing extra hardware or hubs. Plus, you’ll never worry if you’ve locked the door again. Wi-Fi locks can be set to automatically lock at a certain time or when your smartphone is out of range. However, Wi-Fi locks typically need new batteries every 3–6 months and may rely on a strong internet connection to work smoothly.

• Locks and unlocks doors from anywhere
• Check on your home while traveling
• Lets guests in without keys

Bluetooth smart locks are simple to set up. Just pair your smartphone with the lock using the manufacturer’s app. Once connected, the lock will recognize your phone and unlock automatically when you’re within range. Bluetooth locks work within 20 to 40 feet, making them ideal for straightforward setups without the need for Wi-Fi or hubs. However, the limited range may not suit every situation.

• Quick and easy installation
• No Wi-Fi or hubs required
• Built-in encryption for added security

Z-Wave smart locks use special radio frequencies to connect with other devices in your home automation system. This makes them an ideal choice for fully integrated smart homes. Z-Wave smart locks can sync effortlessly with security camera, lights and other connected devices.

To use a Z-Wave lock, you’ll need a home automation system with a controller to activate the lock. You’ll also have to connect a smartphone or other device via the internet. Z-Wave locks may require professional installation but provide great security.

• Keyless entry for convenience
• Voice recognition for hands-free access
• Autolocking to enhance security

Matter over Thread is a new technology that makes it easy for devices from different brands to connect. Thread is the low-power network that pairs with Matter. Unlike Wi-Fi or Bluetooth, Thread networks can fix connection issues on their own and handle more devices without slowing down. Matter over Thread is a stable, fast, simple and reliable connectivity option.

• Connects different devices from different brands easily
• Uses less power than other connectivity networks
• Works well in homes with lots of devices

Smart door locks offer advanced features to enhance your home’s convenience and security:

• Get real-time notifications on your phone. Track who’s coming and going, even when you’re not home.
• Check activity logs to see who used the lock and when.
• Manage access with ease. Use scheduling tools to grant permanent or temporary access for guests or service providers.
• Boost security with tamper alarms. Get instant alerts for attempted break-ins.
• Automate locking with geo-fencing. Outer doors lock automatically when you leave a set range.
• Set auto-lock timers to secure your door after a specific time.
• Use voice commands for hands-free control. Lock or unlock your door through a virtual assistant.

Tip: All smart locks run on batteries with a typical lifespan of 6 months to one year. Most locks emit an audible alert or send a push notification to your phone when the battery is low. Key fobs also use batteries which last 1 to 3 years depending on usage.

A deadbolt adds an extra layer of security. Choose a new smart lock that is compatible with your existing door hardware. However, if you decide you want to keep your existing deadbolt, there are a few smart locks that fit or clamp over the existing deadbolt, essentially turning your deadbolt lock into a smart lock. Installation can be complete in as little as 15 minutes.

Make sure any smart door lock that offers remote access has a locking system compatible with your smart hub protocol: Wi-Fi, Bluetooth or Z-Wave. Even the best smart locks are vulnerable to hacking. Keep your software updated and use strong passwords.

Keypad and key fob smart locks offer versatile and secure ways to access your home. Keypad locks allow you to enter a code using the number buttons on the door. Key fob locks unlock with the press of a button when you’re in range. Most smart locks also include a traditional key option.

You can create custom keypad codes to share with service technicians or neighbors while you’re away. Advanced models even offer fingerprint unlocking for quick, secure access.

• Multiple unlocking options for flexibility
• Custom codes for temporary or shared access
• Advanced encryption for enhanced security
