Logitech's doorbell, which somehow managed to sneak onto Apple's online store late last year without any previous announcements is here, and it includes everything that you would expect from a HomeKit Secure Video-compatible doorbell: great design, easy installation, excellent visuals, fast response times, and timely notifications, the Circle View Doorbell has it all. Of course, no HomeKit accessory is perfect, and with some rather steep requirements and limitations, the Circle View Doorbell isn't quite a doorbell for everyone. Let's dive into what makes the Logitech Circle View Doorbell an insta-buy for HomeKit fans and a pass for those outside of the Apple ecosystem.
