Does this work in Argentina ? I will travel there to film a miniseries so I want to buy 6 of these!
Hollyland does not recommend using the Hollyland Solidcom C1 Pro-4S Full-Duplex ENC Wireless Intercom System with 4 Headsets (1.9 GHz) outside of North America because it is made to work according to frequency laws within North America. However, some folks have successfully used this system outside of North America and its efficiency in your intended region would ultimately depend on that region's wireless frequency laws.

Will this work over walls / 2 floors?
Sorry but not. The walls will influence the transmission of wireless signals greatly. The wall's obstruction will reduce the Solidcom C1 wireless signal and communication performance. Thus, we do not recommend the user use the intercom device between walls.

can I buy a 4 pack and latter ad some more headsets ? will they all work together ?
Yes, you can. The master headset support pairs with up to 7 remote headsets. Thus, the latter purchased remote headset can pair with the master headset if the firmware version and country version are the same. Also, if you are with the requirement to separate the users into A, and B different groups, UAC and cascade functions, the C1 Pro Hub is needed.

If I buy two separate Pro-4S system, can I use them near each others? Or will there be some sort of interference?
