This WiFi security camera earned The Best rating from the Hammacher Schlemmer Institute because it provided the best audio and video quality and was the easiest to set up. Its speakers and microphone provided the clearest two-way audio, its camera the clearest 2K video resolution and night vision with a 32.8' range. It connected to a 5G network automatically without an ethernet cable, and its speedy app allowed setup via QR code or WiFi in addition to providing easy movement of the camera's 360° pan and 96° tilt.
