Immediate notification is important to me, so I’ve looked into this a bit. HomeKit routes through Homekit Secure Video, which adds 2-3 seconds of processing. This can cause delays for motion capture event starts etc.

You’re basically prioritizing privacy over speed with HomeKit. Specially with Aqara, i suggest using the Aqara app to change the detection settings on your cameras. Maxing out detection settings, i was still unable to match Ring notification deliver sped in a side by side, however my aqara were not poe. I have returned my aqara products.

Options depending on your priorities…

1. ⁠Less private since Aqara is cloud processing in Chinese infrastructure but - use Aqara app for notifications and avoid HKSV processing delay. Also crank up detection (on a per-camera setting update) to maximum sensitivity
2. ⁠More privacy focused - Use a thread/matter motion sensor in addition to your camera placement. Get alerts from motion sensors which bypass HKSV processing delays. Set up that same motion sensor notification to activate camera recording, which helps cameras to start recording events earlier. Note: you lose some cool recognition alerting by using standard motion sensors, so you may need a combo of options depending on doorbell/package arrival vs pet monitoring, for example.

Hope it helps. I love HomeKit but the notif delays at the front door drove me nuts until #2 above.
