Safeguard Supply Long Range Wireless Doorbell for Business and Home - ERA-UTDCR 4000 ft Range | Push Button or Magnetic Door Contact Transmitter

I walked 1/4 mile away from receiver and had 4stucco drywall framed structures and 3 Rockwall fences between transmitter and receiver. It worked great. I intend to use this in the Philippines through a stainless steel gate and a concrete house wall.

So far, this wireless doorbell works very well in my home. The doorbell part rings just fine upstairs when the ringer button is pressed downstairs. There's a significant distance between them, so we are very satisfied with this product at this time.

Straight forward installation. Just pair and install. Nothing complicated. Would definitely recommend. Transmitter connected to receiver (where others fail).

Easy to set up, and worked great at long range through some metal doors and walls that other wireless doorbells we tried could not. Also, receiver can be set to ring very loud, which is nice if you have a noisy work space. Time will tell if the transmitter will hold up to the elements of the weather.

I have tried the 1000' and the 1300' foot range doorbells - even one that claimed to go through "4 walls" and they all did not work. This one did and does every time.

I've successfully installed this door chime inside a package drop box. The box is about 500 feet away and the signal is getting through the steel drop box door, landscape vegetation and a masonry wall. The only gotcha is making sure that both the transmitter and the receiver are mounted vertically. My first install had the transmitter slanted matching the angle of the package drop door flap. The result was some missed signals. This was the third device I tried and the first one that seems to work reliably. Update: The unit sometimes fails to trigger. It works when I test it after a failure. It has failed 3 times in the last 4 months out of maybe 30 deliveries. minus 1 star for being a little unreliable.

I got this for an elderly relative who lives about 1,300 Feet away to use as an alert, not for emergencies. I wanted a long range, loud doorbell, that would fit in her pocket. But one that would alert me that she needs something, rather than calling 911. She already has one for 911. This works great. Recommend if you need a loud long range doorbell.

I love when it goes off, scares my coworkers. We use this for the back door

Habia probado otros aparatos con alcance de 300 m y no llegaban hasta caseta de vigilancia. Este si alcanzo a timbrar desde dentro del elevador hasta la caseta de vigilancia. He querido comprar otro timbre transmisor para que sirva desde otro elevador hacia el mismo timbre receptor, pero no lo he podido localizar
