Apple says the Apple Intelligence features in the Home app for HomeKit Secure Video cameras require a 2TB iCloud+ subscription. The requirement is described in release notes for the third macOS 27 “Golden Gate” beta and is expected to apply across iOS 27, iPadOS 27, and macOS 27. The Home app features include written summaries for motion alerts and the ability to group activity from multiple cameras into a single view or described event, with natural-language search and consolidated notifications. Apple previously indicated that some Apple Intelligence capabilities would depend on an iCloud+ plan, but it did not specify the tier ahead of the Home app detail. For HomeKit Secure Video, a paid iCloud+ plan has long been required: the 50GB tier supports one camera, the 200GB tier supports up to five, and the 2TB tier allows an unlimited number of cameras. The HomeKit Secure Video cloud storage does not count against the iCloud storage limit, so the full 2TB allocation remains available for photos and other data. Apple is also separately increasing HomeKit Secure Video recording support to 4K with the OS 27 updates.
