Physen Wireless Doorbell support up to 4 remote transmitters and 4 receiver chimes extension, with waterproof push buttons and working distance about 1000 feet.
Verry helpful video. The directions that came with the product were not written well and the video made it clear on how to pair transmitter and reciever. Also the idea of putting all the components in a single workspace and using a powerstrip made the whole process easier.
I bought something similar. They had hard to get batteries in the remote, that do not "pop out" easily, so after no time at all the batteries have run out, searching for a device at home. If only the battery only was used when you press it. It ended up a big waste of money
The battery in remote button can be used for 4 to 6 month, when battery runs out, you can use a mini screwdriver (which include in the box) to open the remote and change a new one.
It doesn’t work. Can’t change the ring tone sound. Have to use the default to get the thing to work at all. And I have tried every variation of this, it doesn’t work.
when you install that transmitter outside your door and then plug in the receiver inside the door, it is impossible to quickly get from inside to outside in time for the two devices to pair... so it is not easy to change the tune in a paired set - unless I take down the transmitter and bring it indoors to place close enough to the receiver to go through the pairing process. This is a huge flaw in an otherwise well made product.
