This review is from: WC121 Wired Intercom System Gate Entry for Home/office Doorbell interphone
This works more like a hard wired baby monitor, which is what i wanted. i use it for my 7 yr old son and we call it the "intercom system" because saying baby monitor would just not work for a 7 yr old :)
4x AAA battieries go into the master side of the two intercoms. The master side can be used to turn off/on the system. With the system off the Non-master side can only send a squak to the master speaker by using the talk button. With the system on, the master side can hear everything in the non-master room no matter if the talk button is pushed down or not. Also, with the unit on, the non-master unit CANNOT hear anything from the master side unless the button is pushed down.
Like i said, it is a hard wired baby monitor that allows you to talk back if you want.
