     today introduced a new product category to its Arlo line of smart home security devices -- the Arlo Audio Doorbell and Chime.

> Due out this fall with pricing not yet confirmed, the Arlo Audio Doorbell is a battery-powered buzzer designed to replace your existing doorbell. Interestingly, though, Netgear took a different approach than Nest, Ring, August and other major competitors.
