Please note that when the Halo camera is in dock mode, it will only generate baby sleep analytics. You can read more about it at https://support.hubbleconnected.com/knowledge-base/how-can-i-activate-baby-sleep-analytics-on-the-halo/.
If you use the Halo camera in a desk mode, it should record* motion-triggered events provided that you have activated motion video recording in the camera sensor settings.
* Note that you need to be subscribed to one of the subscription plans in order to record motion-triggered events. You can review plans at https://hubbleconnected.com/pages/hubble-for-motorola-monitors.
