At risk of having the whole Internet scream out in pain because portrait video is the worst evil in the universe, I would like support in the app for recording portrait video - I have a camera on the wall to one side of my front door, monitoring the front of the house. The best coverage is achieved by turning the camera 90 degrees on its axis. This avoids half the picture being wall. Putting the night-vision LEDs furthest from the wall also means that splashback from the wall doesn't ruin nighttime exposure.
At the very least, the ability to reorient the timestamp. The app should default to "fullscreen" viewing for a portrait camera on a phone, and there should be the option of 90 or 270 degrees rotation from "normal" to allow for all mounting options. If possible, native recording of portrait video to the microSD so that the file is 1080x1920 etc.
Also, much more configuration for the timestamp would be great: The current 18.104.22.168 fw in 1.0.5(EU) app renders ten minutes past midday as "00:10 PM" for the GMT+0 London timezone.
