Rodann ElectronicsTXRX1000A Indoor Wireless Transmitter and Receiver 500 Foot Range 70dB

This is my second doorbell like a repeat order . The first one is working like a baby since 4 years or so . So I did not want to take any chances . User can control the unit very easily . Thanks for such a good product guys

I've been in C store business for 29 years and everytime I had the new locations I installed this .It last forever.There are many less expensive de vices out on the market, this is most professional and reliable.

I have a 4,000 sq foot commercial building. The receiver is at the front door and the buzzer is 75 feet from the front door with 2 interior doors between. The buzzer picks up the signal perfectly from the front door, no problem. We also have a loud repair shop and we can hear the buzzer almost all the time unless we have the grinder going. Otherwise the buzzer can be heard over all basic shop/mechanic noises.

This product works well as an overhead entry alert in our storefront. It was easy to install and the wireless battery operated motion sensor is convenient (we haven't had it long enough to learn how long the 9V battery actually lasts...). Changing the sound is done by varying combinations of DIP switches which makes it a little annoying to try out different tones, but it works. The volume control is also handy to dial it in where you need it. Overall this is a good product that works as advertised.

I am very happy with the wireless transmitter. I operate a small business. We have a wired "dinger" for the back of the store, but I could never hear it in my office. On the days when I worked by by myself, I'd have to jump up and check to see if customers were in the parking lot. It made for a less productive day. Now, I know when customers come in, and they don't catch me asleep anymore! (Just kidding!!) The service was really fast as well.

Bottom line, this is a quality system that works just as expected.I run a small restaurant and the alarm has already paid for itself 30x over in just a few months by allowing my employees to concentrate on prep in the kitchen with the confidence that they won't miss customers who walk in.Less standing in front waiting for customers in the morning and on slow days between lunch and dinner = happier, active, less bored employees and lower overall labor expenses! Win, win!

Great detector. We installed it at the front of the firm under a counter. Downgraded one star because the detector could be a bit smaller. It stands out more than I would have liked. But it works great.

No talking to answering machines, real live customer service that is polite and patient. This is a good quality you can’t put a dollar amount. PERIOD!
