For the house with no doorbell wiring, a dead transformer, or a front door nowhere near a chime circuit. The ADC-VDB780B runs entirely on a rechargeable battery pack, so the install is choosing the best viewing angle rather than working backwards from where the wire happens to come out of the wall.
Built for the installer
The 9540 mAh pack is rated up to six months between charges and recharges over micro USB in about seven hours. IP66 and a 160-degree horizontal field of view. A 10-degree tilt wedge is in the box, and the optional wedge kit (ADC-VDBA-780B-WMK) adds 15-degree tilt plus 15 and 30-degree pan wedges for doors on perpendicular walls.
Read the connectivity requirement before quoting. This doorbell does not join the customer's router directly. It must connect over Wi-Fi to an Alarm.com Smart Chime (ADC-W115C), Smart Gateway (ADC-SG130), IQ Panel 4, IQ Panel 4 Hub, IQ 4 NS or Qolsys IQ WiFi 6, all sold separately. If none of those is on site, the job needs one added.
