Netgear's Arlo line consists of security cameras for indoor, outdoor, and on-the-go monitoring. With Wi-Fi baby monitors all the rage, it's not shocking that the manufacturer has set its sights on "guarding your most precious asset." What is pleasantly surprising is just how well it pulls it off. On the outside, the $250 Arlo Baby has little in common with the distinctive look of other cameras in the Arlo line. It's essentially two roughly tennis-ball sized spheres, one stacked on the other, to create an hourglass shape.
