Doorbell with HD camera
With this you can see who is visiting you wherever you are via your mobile phone.
Can be used with power connection or via batteries. The batteries can film up to 30 hours between each charge and charged with the included Micro USB.
Use external chime bell with the camera if you wish. This is not necessary as it rings on your mobile phone and your family's mobile phones (you choose how many you connect), but you may still want one in the garden, for example. If you want a chime receiver it will be sent in random color. (Black or White)
Can use SD card to store (smart as security when attempting burglary since the camera has a motion sensor and automatic movies)
