# Upgrades

Owners buy property upgrades from `/housing` → property → **Upgrades**. Each upgrade is either a single tier or a level-up tree.

| Upgrade                | Tiers | Effect                                                                                            |
| ---------------------- | ----- | ------------------------------------------------------------------------------------------------- |
| **Cleaning**           | 1     | Disables dirt spawning.                                                                           |
| **Cameras**            | 3     | Adds 2, 4, or 6 cameras plus a video filter.                                                      |
| **Alarm**              | 1     | Enables [alarm dispatch, sound, and SMS](/paid-resources/rcore_housing/features/alarm-system.md). |
| **Peephole**           | 1     | Door viewer (SHELL / IPL only).                                                                   |
| **Anti-Burglary Door** | 3     | Raises lockpick difficulty per tier.                                                              |
| **Eco**                | 3     | Discounts utility bills by 10 / 20 / 40 %.                                                        |

For prices and per-level features, see [upgrades configuration](/paid-resources/rcore_housing/configuration/upgrades.md).

## 📷 Cameras

Cameras are placed from the property UI after purchase. Each level raises the camera cap (2 → 4 → 6) and swaps in a different video filter for the live feed.

The list of camera prop models is `Config.Cameras` - see [main config](/paid-resources/rcore_housing/configuration/config.md). Add custom camera props there.

## 🔐 Anti-Burglary Door

The Anti-Burglary Door upgrade does not change the door visually - it raises the lockpick minigame difficulty. The per-level minigame settings are in [raid configuration](/paid-resources/rcore_housing/configuration/raid.md).

| Level          | Lockpick experience |
| -------------- | ------------------- |
| 0 (no upgrade) | Easy                |
| 1              | Slightly harder     |
| 2              | Hard                |
| 3              | Very hard           |

## 🌱 Eco

Each Eco level multiplies the property's utilities bill by a modifier:

| Level | Modifier | Saving |
| ----- | -------- | ------ |
| 1     | `0.9`    | 10%    |
| 2     | `0.8`    | 20%    |
| 3     | `0.6`    | 40%    |

The modifier is applied at bill generation time - see [Billing and Rent](/paid-resources/rcore_housing/features/billing-and-rent.md).

## 👁️ Peephole

{% hint style="info" %}
Peephole is restricted to `SHELL` and `IPL` interiors. MLO interiors are skipped because they handle doors with their own collision.
