Question
QUESTION: Dear Prof Cleggsan

Can we build a Smartphone Doorbell app which will trigger Doorbell rings?.

The smartphone circuit hardware have to be modified to make it work?.

Thanks
Prashant

ANSWER: I am not clear on what kind of implementation you are thinking.  Do you want the smartphone to be mounted on the doorbell for visitors to operate? Or are you thinking of a visitor who has the doorbell app and wrings the smsrtphone of the resident?

There are in the marketplace now several versions which requires mounting a hardware doorbell button on the outside of the door which contains a video camera and microphone which when operated by the visitor causes the smartphone to bring up the video and voice of the visitor.  They consist of an APP for the smartphone and the smart doorbell unit mounted outside by the entry door.

See you later.

QUESTION: Dear Prof Cleggsan

Thanks.


The Doorbell manufacturer will supply with the modified electronics hardware and supply a Smartphone Doorbell app which the Consumer will run on his Smartphone.

Using this app, the Doorbell Wirelessly can ring Bells on triggering push buttons on the Smartphone?.

Thanks & Regards,
Prashant S Akerkar

Answer
Yes, simple application of smartphone systems.  Greatest effort must be the button on the door which would need a video camera, audio microphone and WiFi or Bluetooth transmitter in order to establish communications with smartphone.

Here is an example of commercially available such system:

There are other designs that you can find with google or bing.

Hope this helps.
