Choosing a Wi Fi Gate or Door Intercom System

If your search is for a portable intercom station that you place around your home or business for inside communication, there doesn't seem to be one of those available on the market. Similar options utilize wireless frequencies rather than Wi-Fi. However, we have found that the Amazon Alexa devices like the Echo Dot are about as good as you can get for this application. You just use the "Drop In" feature described here: Amazon Alexa
What we specialize in is Wi-Fi door or gate intercoms. These intercoms communicate via either CAT-5 cable or Wi-Fi through your home or business router to an App on an iPhone or Android smartphone or tablet PC. They not only provide two-way audio communication, but also one-way video from the intercom to the App.
These WiFi intercoms are available for single-occupant or multiple-tenant applications like apartment buildings, condo buildings, or multi-tenant business buildings.
