Here is another smart doorbell that lets you see who is knocking on your door from your smartphone. The VEIU Smart Doorbell comes with a 720p camera with 180-degree view and night vision. There is also a 5″ LCD display with 2 GB of internal memory and 2 months of battery life. Of course, you can always use your smartphone to keep up with new events and talk to your guests.
VEIU automatically detects motion and sends an alert with a snapshot to your smartphone. It connects to your home WiFi network and lets you save and share video clips through its display. Expected to ship in July.[Source]
