Buzzerboy is really cool. Yes we know that, so in order for it to work for you here what you need:
You must have a telephony intercom system
This means that when the intercom system in your lobby calls you on your cellphone or landline telephone. You can answer the call, talk to your guest, and press a button on your phone to open the door.
You DO NOT need to purchase any hardware
We have made Buzzerboy’s AI particularly so that it works with your apartments existing system, so you do not need to purchase any new hardware system.
You DO NOT need to an internet connection
Buzzerboy AI runs in the cloud, but it is accessed by a telephone number, so unlike Siri, Alexa and others you do not need an internet connection to make it work.
