# Configure Tamper Alarm on Door Phones

The tamper-proof feature prevents anyone from removing the devices without permission.

The supported tamper-proof method varies by model. There are two types:

- Gravity Detection: Trigger an alarm when the door phone detects a change in gravity.
- Button Status Detection: Trigger an alarm when the status of the button changes.

| Gravity Detection | Button Status Detection |
| --- | --- |
| X916 | S539 |
| R29 | S532 |
| R28V2 | X915V2 |
| R27 | X912 |
| R20 Series | E18 |
| R25 Series | E16V2/V3 |
| A01/A02/A03 | E12V2 |
| A08 | E13 |
|  | DB01 |
|  | A05V2 |
|  | A094 |
|  | X910 |
|  | S538 |

This article takes X915 and R20A as examples.

## Gravity Detection

1. Use the device IP to log in to its web interface. The initial username and password are both admin.
2. Click **System > Security** and find the **Tamper Alarm** part.
3. Enable the feature and set the **Gravity Sensor Threshold**.

The threshold is for adjusting the gravity sensor sensitivity. The lower the value is, the easier the tamper alarm will be triggered by some small movements. It is 32 by default.
