RadioShack 4 Channel 900MHz Wireless Intercom System

Arrived on time, in like new condition. Works extremely well!! I’m very pleased.

There was no informaion in the mannual for the product I received. Actually there was no mannual in the cartoon containg the intercams I received. I was able to access a copy of the mannual on the internet... Nothing about authentication or synchronization!.So far I have not received the link to the seller to contact from you folks at Amazon.If I fail to receive the info I am looking for, I will probably wind up returning the new intercoms. It should be noted that Radio Shack , who is the manufactorer of the profuct, is still in bankrutcy..

Ordered this intercom system after having bad experiences with other cheaper brands. This one has real crystal clear sound and transmits over a long distance up stairs and far away. Would definitely recommend.

Came in original box but was clearly used. It didn't work.Sent back without any problems.

I was looking for a simple, cheap, reliable intercom that doesn't need to be on a special circuit to work.This one needs no special setup, and does exactly what you expect a simple intercom to do, for a fraction of the price of higher end models. It doesn't need to be on a special plugged-in circuit, and voice and sound quality is clear.Plug it in and use it. It works great.

This intercom works great, and the setup was easy. Note that this model is not voice activated, you must press the Talk button and hold it while speaking. I actually like this better, voice activated systems can be flaky.

sound quality.

This intercom is a real steal. Works like a charm. The talk is clear and the unit is simple to use.
