| Door and frame compatibility |
Confirm the door thickness, backset, latch type, strike plate position, and whether the door opens inward or outward. |
A smart doorbell lock may not fit cleanly if the existing cutouts, latch alignment, or frame depth do not match the lock body and camera position. |
Ask: Which door dimensions and existing lock types does this model support without drilling new major holes? |
| Power source and backup access |
Review the battery type, expected replacement method, low-battery alert, and mechanical key or emergency power option. |
Video, Wi-Fi, and lock motors draw power. A weak backup plan can leave users locked out or unable to use the doorbell function. |
Ask: What happens if the battery is flat, and how can the door be opened from outside? |
| Connectivity and app control |
Check whether the lock uses Wi-Fi, Bluetooth, a hub, or a wired connection, and which phone systems the app supports. |
Connectivity affects remote unlocking, video calls, notifications, and reliability at the front door where signal strength may be poor. |
Ask: Does remote viewing or unlocking require a gateway, subscription, or constant Wi-Fi connection? |
| Access methods and user management |
Compare fingerprint, PIN code, card, app, temporary code, and physical key options, including how users are added or removed. |
Homes, rentals, offices, and shared entrances need different access control. Temporary codes and user logs may matter more than extra unlocking methods. |
Ask: Can I create time-limited codes and delete a lost card or former user immediately? |
| Outdoor exposure and installation details |
Verify the stated use environment, camera placement, night viewing method, and whether the exterior unit is protected from rain and direct sun. |
A doorbell lock sits outside, so weather, glare, and viewing angle can affect both locking reliability and visitor identification. |
Ask: Is this model intended for exposed outdoor doors, or does it need a covered entrance? |
