Will my doorbell camera work without Wi-Fi?

Will your doorbell camera work without Wi-Fi depends on type, but most modern smart doorbell cameras like Ring, Nest, Arlo, and Eufy require Wi-Fi to function fully, as they need internet to stream video to phone, send motion alerts, and store footage to cloud. Without Wi-Fi, they will not send notifications, allow live view remotely, or record to cloud, and you cannot view footage from app outside home. Some doorbell cameras have limited offline functionality, for example Ring and Nest can still ring indoor chime if hardwired even without Wi-Fi, and some models like Eufy with local storage can continue recording to internal storage or base station without Wi-Fi, but you cannot access footage until Wi-Fi returns. Wired traditional doorbells without camera work without Wi-Fi, as they use low voltage wiring to chime. If you need doorbell camera to work during internet outage, choose one with local storage and battery backup like Eufy S330 or Ubiquiti G4 that records locally, or have secondary traditional chime. Some doorbells have cellular backup via alarm system. So for most people, doorbell camera essentially does not work as smart camera without Wi-Fi, it becomes just a doorbell button, losing smart features.
