VEIU can be set up to automatically take pictures (snapshots) or videos. This is called Passive Infrared (PIR) motion sensor. Even when VEIU gets disconnected from the internet, you won’t miss anyone, since the snapshots or videos will be saved at the local storage.
The delay time for PIR is completely customizable. Under "Detection Setup", you must turn "PIR Detection" on. A line below that, you would see "Auto-Alarm Delay" and you have several options for the delay from 1, 3, 5, 10, 15, and 20 seconds. Another line down and you would see "Detection Sensitivity", where you can set it to "High" and "Low".
