No, we currently do not offer options to extend the alerts videos stored on the cloud past 10-12 seconds.
However, using a microSD card with the ‘record on event’ feature turned on will allow the camera to record the rest of the footage that the cloud video does not capture. A good way to use this feature is to view the alert video under the Notifications tab first, and if you believe there is more information needed you can then go to the Playback tab and view the rest of the footage.
How the 'record on event' feature with microSD card works: The camera breaks the video feed into 1-minute increments. If motion is detected at any point within a 1-minute increment, that 1-minute increment is recorded to the microSD card. This means that the camera will record continuously when there is motion, and will not record when there is no motion detected.
Note that this is independent of the 12-second alert videos that are captured and stored on the cloud for 14 days based on the camera’s motion detection settings. The 12-second alert videos have a 5-minute cooldown period, so when there is constant motion the camera will record a 12-second alert video every 5 minutes and save that video to the cloud for 14 days. With a microSD card installed and set to Record events only, the camera will save video to the microSD card as long as motion is detected.
