There are several features and measures in place to prevent the theft of a Eufy doorbell: 1. Tamper Detection - The Eufy doorbell is equipped with tamper detection technology. If someone tries to remove or tamper with the device forcibly, it will trigger an alarm and send a notification to the homeowner's smartphone through the EufySecurity app. 2. Secure Mounting - The doorbell comes with a secure mounting system that makes it difficult for thieves to remove it from its position. It typically requires special tools and knowledge to uninstall the doorbell properly.   3. Cloud Storage - Eufy doorbells offer cloud storage options, allowing the recorded footage to be securely stored in the cloud. Even if the doorbell is stolen, the footage remains accessible to the homeowner through the EufySecurity app.   4. Two-Factor Authentication - The EufySecurity app supports two-factor authentication, adding an extra layer of security to prevent unauthorized access. This ensures that even if someone steals the doorbell, they cannot easily gain access to the app and its data.   5. Deterrence - The presence of a visible doorbell camera can act as a deterrent for potential thieves. Knowing that their actions would be recorded and potentially lead to identification can discourage theft.
