## What's improved?

### Improved smoke & fire detection for indoor haze

Smoke & fire detection is now more sensitive to faint, slow-spreading haze indoors. This is often an early sign of a fire starting. Previously, this kind of haze was filtered out as background.

**Note: **This improvement currently requires turning this capability on at a system level. Contact support for assistance if you wish to use this improvement.
:::

**What you should know**

Because the model is more sensitive, busy or cluttered scenes may see more false alarms on smoke & fire rules. Other rule types are not affected. For further tuning, contact Irisity support.

## Known limitations

- Smoke & fire event overlays sometimes don't show, even though the event is detected.
- The range sliders in smoke & fire advanced settings can be hard to drag.
- Face recognition doesn't generate events for static watchlists.
- Users may be logged out mid-session without the stay-connected prompt.
- Upgrading appliances with a single 12 GB GPU (such as CORE100 with RTX A2000) needs extra preparation first. Contact Irisity support before upgrading.
- On some CORE100 units, installation can stop at the alarm-filter verification step. Contact Irisity support if this happens.
