Can an external speaker be added to an old CCTV camera phone to make the voice louder while using MoGo CCTV App?

Absolutely!!

MoGo CCTV app utilizes all the underlying features of the mobile phone working as CCTV Camera.
This allows for the connection of an external speaker (via bluetooth) to make the voice sound louder during 2-way communication.

We have seen customers using this, especially when using the MoGo Mobile CCTV application for :

Parental Monitoring

Pets Monitoring

Dash Camera in the Car

Baby Monitoring

Maid Monitoring

Kids Monitoring

A louder voice through an external speaker can help convey audio messages better and more effectively.
