A doorbell with a camera, microphone, and speaker that streams to your phone.

- Integrates with locks, lights, and cameras
Direct answer
A video doorbell is a doorbell that includes a camera, microphone, and speaker, so residents can see and speak with visitors from a mobile app or in-wall panel. It records events, supports motion pre-roll, and integrates with locks and lights. In UAE villas Smart Citizens pairs doorbells with wired 24 V transformers, PoE, or dedicated intercom cables for reliability in high heat.
Detailed explanation
A doorbell has three power options: wired 8–24 V AC into an existing chime, PoE from the network switch, or battery. Wired options are strongly preferred in UAE villas — heat, dust, and long distances quickly age batteries.
Practical value is not in the video alone: pairing the doorbell with the smart lock, a hallway light, and a camera creates a verified answer/unlock/entry flow that logs into the customer portal.

Common mistakes and best practices
What to avoid, what to do
- Prefer PoE + local NVR for reliability
- Add an in-wall panel or Echo Show for the elderly
- Trigger a hallway light on doorbell press at night
- Battery doorbells in unshaded UAE sun
- No secondary chime, so calls are missed
- Recording to cloud only, with no local NVR backup
Frequently asked questions
Frequently asked questions
Do I need a subscription?
Local recording works without one; cloud clip history usually needs a plan.
Do doorbells replace an intercom?
For a single villa yes; multi-tenant buildings still need an intercom system.
Can it unlock the door?
Yes if the doorbell is integrated with the smart lock via the hub.
