There are some 50 sounds to choose from. There are two receivers. They plug into a 110v outlet. There are three “transmitters” (I put on doors). You can choose a different sound for each receiver, depending on which door is opened.(the front door opens-ding-dong, the back door opens-honk-honk —- but on both receivers). The sounds are loud and clear. The problem for me is that when any one of the three doors are opened, both receivers “chime” (per the chime you select which can be different for each door). They should have included a “silent” sound also. I wanted to know if the back door opened at night (on the back room receiver), but never the front door. There are off and on switches on each transmitter, but it’s easy to forget to turn one off (or back on during the morning). Please make a “silent” sound also. I don’t care if the front door opens during the daytime (which causes the back door receiver to also chime-I selected the least annoying). NOW: I have the third transmitter on the deck out away from the house. About 150 feet away. The receiver is by the back door. It works that far, through the back door (there is a doggie door in it). So kudos for the distance (but if I move the receiver to the back bedroom it doesn’t reach). Normal for going through so many walls. They have a button battery, so I’m not sure how long it will last. I wish they were just USB rechargeable. Programming them is easy enough, read the short instructions. There seems to be no way to program the receivers like below: Receiver #1: Front door opens: ding-dong. Back door opens: honk-honk Deck door opens: bark-bark Receiver #2: Front door opens: I want that silent. Back door opens: honk-honk Deck door opens: bark-bark

Easy to install, good price, good quality. I like that you can turn the volume down, they are exactly as described and function perfectly. Chime every time the door is opened.

This is a pretty simple to install and use door alarm. Properly installed it provides a plethora of alarm tone options loud enough to almost raise the dead and inform you the door has been opened. When turned on, it has not failed. There are times I do not want it be armed and there is a manual off switch. It would be nice if it had a remote for on/off and volume control but this was a low priced system and is totally functional as is.

Sure it works and has a long range and does have MANY different chime sounds but I can’t get any of them to work when you open the door except the ding dong that is its default. I’ve followed the instructions multiple times with no luck. I emailed the support address but no one ever responded. If you don’t want to hear only a ding dong door bell sound, don’t buy this device.

These work well and are easy to install. They are loud enough to hear. The reason for 4 stars is that if you aren’t careful it will fall off the door and have to be put back several times whenever you are turning off and on.
