There is one setting on indoor 2k pan & tilt cam I don’t really understand the use of.
Interval time (mins)
Interval time between event notification and recording.

Why would you want the camera to wait some minutes after notifying an alarm event BEFORE it starts recording? Surely you want that as short as possible or even pre event recording !


PLEASE…Someone at Eufy, can you expound considerably on the “INTERVAL TIME” setting for the indoor 2K PTZ cam?

The explanation in the app is beyond poor. It does NOT adequately instruct users as to what the setting does, much less how the individual (user selectable) time variables actually CHANGE the behaviour(s) of the cameras recordings and/or the way(s) in which these settings modify the triggering of notifications within the app. I’ve attempted to discover what modifying these time intervals does in my specific situations but it is not clear what is actually occurring.

The only thing I can say beyond a shadow of doubt is that notifications are routinely LATE coming to my phone and often are occurring AFTER I’ve opened the app to check for recorded video due to being already fully aware that I should have been notified that someone was on my property.

It is puzzling and frankly irritating beyond words to be viewing a recorded clip and THEN suddenly a notification for this event pops up …as if the event is just occurring! This despite the event occurring minutes to even hours earlier. The app is a HUGE battery drain and it does NOT get better with successive updates. If anything, it gets worse.

So, as such, I do need to know if this interval time setting in any way relates to WHY notifications are far too often LATE. This is not all the time, but it is most of the time. I have the app set to allow in the background unlimited bandwidth and no battery optimization because I don’t want the app killed otherwise the notifications certainly won’t come through! I wish I didn’t have to set the app to other than OPTIMIZED on my Galaxy S22 Ultra because it shouldn’t require unlimited battery usage and the app is already ill-mannered when it comes to chewing through smartphone and tablet batteries!
