Firmware updates happen periodically to improve your camera experience and introduce new features for the camera.

In Apple HomeKit, a powered on and connected camera checks for new firmware automatically every night. If new firmware is available, it is automatically downloaded and installed and cannot be requested on our support channels. The rollout of firmware may happen over the course of days or weeks and therefore it is normal and expected that one or more of your cameras is updated before the others.

NOTE: If you are using a router secured with HomeKit, you must ensure that your settings are set to 'No Restriction' or 'Automatic' for any updates to be installed. You can learn more about this at the Apple support site.
