First, the Snap is recording as long as it is: connected to good WiFi, receiving power and not disabled from recording in the Snap app.
With the Snap, you can view live footage. Furthermore, you can view past footage based upon your cloud plan. The available past footage is based upon your cloud plan. For example, if you have the 7-Day Cloud Plan, you can view footage from up to 7-Days ago.
First, open the Snap app and press the plan button on the camera you wish to view. This will take you to the live page. From here, you can have a live view of what the Snap is viewing.
To view previous footage that your Snap has recorded, you would press the “History” button at the bottom of the live page. This will take you to the History page. From here, you can scroll back in the timeline to look at certain hours and choose which day to view footage from.
