This product is prone to line interference and can only use two channels (which you have to remove it from the wall to change). Even if your intercom stations have 4 channels, this unit can only use only "A" or "B" which limits your ability to bypass interference on your home wiring. If the unit is installed in a sunny location, the heat can also cause it create it's own static. Having said that, it does do a reasonable job and does allow you to find out who is at the door before opening it or to tell the person at the door that you will be there shortly if you are unable to get the door right away. It is a good start and even though it has been out for a few years, I hope they can improve upon it in the future.

I am more than pleased at the quality of the products I have ordered from you and also pleased at the quick and courteous service from your sales staff. I will continue to order products from your wonderful Company... Bob S.

Love the product, none other like it, easy to install, but it has a short life span even in sheltered location.

System works correctly.

Worked perfectly with my gates which are 900 feet from my house intercoms!

Firstly there can be a lot of static. it works best at night when most of the electrical usage is at a minimum. However when the product was new, I had to disconnect the front door bell station in the middle of the night a few times. The static was so loud that we couldn't sleep (probably disurbed the neighbours too). It is not well thought out: 1)The channel buttons are not logical. They can all be pushed in at one time. This would be solved by allowing only one channel button to be pushed in. 2)The door bell station only works on channel A. So if we lock one of the stations so that we can hear the baby, the person standing at the door can hear the noise in that room too. 3) If we use channel B for the baby we have to change the station to channel B in the room we listen from. Then, we won't hear the door bell.
