Home security company Brinks is jumping into the smart lock arena with the new Array Smart Deadbolt, on display at CES 2018. The Array is a cloud-connected, Wi-Fi enabled smart lock that replaces your existing deadbolt.

The lock is powered by a rechargeable lithium-polymer battery and has a backup solar panel that can capture the full spectrum of light to charge the lock. Unlocking the Array can be done through traditional keys, a backlit keypad or the Array app, available for iOS and Android devices, including the Apple Watch.
