I agree that snoozing notifications (turn on privacy mode for X minutes) would be extremely useful. My Canary Flex provides a view of my driveway. However, when I take the kids outside to play, it is annoying to get multiple nuisance Canary notifications on my phone. It would be perfect to click a quick-action snooze button on the first notification to enable privacy mode. I would have to take a guess on the snooze length based on how long I think I will be outside, but this would still eliminate countless extra notifications.
The snooze feature also prevents situations when I forget to turn off privacy mode. Currently, I manually enable privacy mode, but never remember to turn it back off. I have an automatic task set up through Wink to disable privacy mode every morning at 8 AM, but that means I generally miss notifications while the camera is in privacy mode from, say 7 PM until the next morning.
