Doorbell cameras can help deter package thieves and other burglars, while also allowing you to see and speak with welcome visitors. This standout from Ecobee offers a wide 175-degree vertical field of view, allowing you to clearly see packages and other objects pushed right up against the door. It’s hardwired, which makes for a trickier installation, but you won’t have to worry about replacing or recharging batteries. You can also communicate with whoever is at the door through the device’s two-way audio (including through the app on your phone if someone comes when you're away from home). One tester found the app “highly intuitive” to use while another tester praised the camera’s “expansive viewing angle” and “excellent video quality.”
