How many microphones can I use with Zummer-GSM?
There is only one microphone in our standard package at the moment. We tested a number of parallel-connected microphones and found out that using them in the same room did not prove to be very effective. One microphone is sensitive enough. In the near future we are going to produce an optional microphone switch to connect up to 4 microphones. These microphones can be placed in different rooms to ensure the whole house is under control.
