Hi, please tell me about the security on these. Can someone eavesdrop on our conversations? Is the communication encrypted?

I purchased these units less than two months ago. Recently I have heard multiple conversations coming through the intercom. The other night I had to unplug my units because of the chatter.

I want to use in a Doctor office. Does it have a beep to notify? I want the doctor to press a button and let us know he is on his way out of room.

Hi, Thank you for your attention for Wuloo wireless intercom system. Of course, this intercoms have a beep function to notify. There has a CALL button on each unit, press it and the other devices with the same channel code will receive the ring.
