Here are a few things to consider about the Arlo Pro 4 hardware: The Arlo Pro 4 comes in two colors, black and white. You can pick whichever color you like better or think would be more inconspicuous in your yard. The Arlo Pro 4 is wireless and comes with rechargeable batteries. These batteries are supposed to last six months, although our tests show they probably won’t last quite that long. Either way, when the batteries come up empty, you can remove them from the shell and charge them. The Arlo Pro 4 has free local storage if paired with an Arlo base station or SmartHub. (Local storage means you’ll use an SD card to store footage instead of the cloud.) The Arlo Pro 4 works with other security and [tooltip]smart home[/tooltip] devices from Amazon Echo, Google Home, IFTTT, Apple HomeKit, and Samsung SmartThings. This is a huge win if you’re into the smart home scene.
