I encourage EUFY to consider these accessories.
1. Screw-in mount for out doors
2. Silicone covers - would do several colors, a small brim would prevent water on the lens
3. USB charging cable at different lengths that fits in the waterproof slot and an outdoor charger
4. IFTTT integration with a host of devices. Would target the biggies first samsung, alexa, google, apple, wink etc.
The door bell without subscriptions as a standalone device and a 16 to 24 VAC supplied device are the next products to develop. The ring door bell has much to be desired. The nest costs too much.
Perhaps extension of the hub to do zwave, zigbee, wifi, alexa etc home automation with an open API like the samsung platform
