The Video Doorbell Pro measures 4.35 x 1.35 x 1.12 inches, enabling it to fit on almost any existing doorway.
The Video Doorbell Pro requires an existing wired doorbell system to provide power to the device. In addition, the Video Doorbell Pro does not currently support a wireless chime.
It also requires a WiFi network to function. The wireless router must be capable of broadcasting at 2.4GHz and with an active Internet connection to stream video. Most networks fulfill this requirement.
You’ll need an iOS or Android smartphone to set up the doorbell, although once set up, it can be viewed through web browsers as well.
