The Good: Netgear's $250\/\u00a3300 Arlo Pro provides indoor and outdoor security monitoring in a single camera. You get seven days of free event-based cloud storage, and its rechargeable battery is supposed to last for up to six months. The Bad: The Arlo Pro costs more than its competition, and it was difficult to see what was happening in night-vision mode. Some customers won't want to deal with a hub accessory during installation. The Bottom Line: The Arlo Pro is an even smarter DIY cam than Netgear's first-gen Arlo, but competitors are closing in fast with innovative designs and updated apps. There's a lot to love about Netgear's $250\/\u00a3300 Arlo Pro security camera. Its rechargeable battery is simpler to deal with than the original Netgear Arlo's expensive and hard-to-find CR123s. The Arlo Pro also adds in two-way audio so you can tell any unwelcome guests to get off your lawn, as well as receive audio alerts. Otherwise, this indoor\/outdoor DIY home security camera is essentially the same as the first-gen Arlo, which Netgear still sells for $180\/\u00a3135. That's mostly a good thing, since Netgear nails the features category with seven days of free cloud storage, a wide-angle lens, a loud siren built-in to the Arlo Pro's next-gen Wi-Fi hub and compatibility with IFTTT and Samsung SmartThings platforms. The Arlo Pro is a solid choice, particularly for outdoor, scalable security since Netgear sells multicamera kits and the hub can help extend the camera's reach beyond that of your WiFi router. I'd also consider the $199\/\u00a3159 Canary Flex, as it has similar features with a more streamlined hub-free design. Arlo Pro up closeThe Arlo Pro shares a lot of similarities with the original Arlo camera. The main difference lies in the type of batteries Netgear uses. Instead of needing CR123 batteries to power a single Arlo camera, you get a single rechargeable battery with the Arlo Pro, designed to last for anywhere from four to six months. Netgear also improved the required hub accessory that comes with your Arlo Pro purchase. Not only does the router-connected hub help extend the Wi-Fi range for longer distance outdoor camera installs (around 200 feet when I tested it, although Netgear claims it has a "300+ feet line of sight" range), this updated version also has a built-in 100-decibel siren.You can use the related Android or iPhone Arlo app to program the siren to sound when the camera detects activity. The one hiccup is that the siren sounds from the hub, not from the cameras. So, if you have your cameras installed outside around the perimeter of your yard and the camera detects activity, the siren will only sound inside your house. 100 decibels is pretty loud, but it might not be strong enough to scare off someone lurking around outside preparing to steal your car. The Arlo Pro also adds in two-way audio via a built-in microphone and speaker so you can communicate with someone at your front door or tell your dog to stop chewing on your shoe. The Canary Flex and the Logi Circle are two Netgear Arlo Pro competitors. Check out the chart below to compare their main features and specs:The Arlo Pro has a definite advantage over both the Canary Flex and the Logi Circle in terms of features. Its rechargeable battery is supposed to last longer, it offers free 7-day event-based cloud storage and it works with IFTTT and SmartThings.And while I didn't test this camera over several months to fully explore its battery life, the battery indicator in the app is still showing that it's fully charged after roughly a week of testing. The Canary Flex is still showing a mostly full charge, but it's closer to 80 or 90 percent charged at this point. At the same time, the Arlo Pro costs more than its competitors and some people won't want to deal with the added hassle of installing the related hub -- especially if they have no need for a Wi-Fi range extender.
