Here is another smart video doorbell that lets you monitor your door from your smartphone. The VEIU comes with a 720p camera with a 180-degree view and night vision. The Monitor has a 5″ touchscreen display and lasts up to 2 months. The companion app lets you hear and speak to visitors.
The VEIU is compatible with iOS and Android devices. It has a motion sensor to detect activity and send you a snapshot. No subscription is required either. More info is available here.
