Review on Rodann Electronics TXRX1000A: Indoor Wireless Transmitter and Receiver with 500ft Range and 70dB Signal Strength by Zachary Spaulding

This product would work well as our store entrance announcement. It was easy to install, and the battery-powered wireless motion sensor is handy (we didn't have it long enough to know how long the 9-volt battery actually lasted). Changing the sound is done via different combinations of DIP switches, which is a little annoying when trying different tones, but it works. The volume control is also handy to set it where you need it. Overall this is a good product that works as advertised.
