Long Range Wireless Doorbell for Business and Home - ERA-UTDCR 4000 ft Range - Heavy Duty Weatherproof Push Button or Magnetic Door Contact Transmitter

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.

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.

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

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 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.

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.

Super easy to install, I was able to use our existing magnets on our doors for our Fireworks Business. Customers can now ring the bell to enter from 2 doors or if the door is open for business our Pyros are notified a customer has entered and know to go help from in the back warehouse which makes us much more productive.

What a pleasant surprise. I installed this for a elderly, hard of hearing person. I installed the "chime" in the front hall and it resounded through the house and for a person of normal hearing it would be sufficient. My client also spends a significant amount of time in her TV room and as you can imagine the TV volume is Loud. I purchased and installed an additional chime for that room which really did a good job. The chime has 12 chimes (sounds to choose from) and 4 volume options. The chime receiver can be used to activate all manner of things (relay and voltage outputs). The button itself is somewhat large but it claims to penetrate most building materials. I haven't used it for that. Overall, the product worked well, the instructions were clearly stated. If I had the need I would certainly purchase it again.

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
