Wireless communication problems

[dan_man555]

My grandparents have this issue where they want to communicate with each other in different parts of the house without shouting.

 

I thought the obvious solution was walkie-talkies, but after 3 days the batteries went dead, and they had no intention of stocking up on AAs. Using rechargeable batteries would be too cumbersome as well.

 

If anyone knows of a price conscious solution, that would be great.

EDIT: Some home phone systems have intercom calling built in (Well mine ).

MegaPhones? Lol. Get them like a cheap Android tablet, give them skype and let them video each other with wifi in the house. lol IDK for anything cheaper. Have you tried 2 cups and string?

Inhouse phones? Or speakers? Its oldschool solution which basicly does same as walkie talkies but with wires.

Most phones have the closed loop communication feature. (Wireless ones)

Or you can use google hangouts through Gmail
