It works!
These serve a simple purpose but are also useful. They can be used to monitor another room (like a baby monitor) and I may use for them for that purpose on occasion. Currently my use is to communicate from a house to a detached garage/workshop area. They work fine at ~160 feet or so through multiple walls. The sound quality is a bit worse than I had expected, even when used closer than that, but sounds/voices are still easily understood. There is a lo-fi quality to the sound transmitted that was a little disappointing at first but easy to get used to. The intercom system can be expanded too, which could be a great use for a small business. There are multiple channels that can be paired up to use - a push of one of the number buttons is all it takes to change. There are also 3 channels (A,B,C) that can be selected in case there is interference on one. I tested them to see if they would improve the somewhat "lo-fi" sound quality, but they didn't. I didn't expect them to though since it's more for noise interference which I didn't feel I had, but wanted to at least test to make sure. Additionally, the units are a good small size as well - perfect for their purpose!

Makes multilevel homes easier to communicate in!!
Recently my dad and sister had to move in with my family. They fixed up a couple rooms in my basement. Our usual mode of communication was to stand at the top of the stairs and yell down to them. I am so grateful to have found these. I no longer have to yell and just hope my dad either hears me or understands what I say. They were super easy to set up and they work great. You can hear whoever you are speaking to clearly and the volume is adjustable so we can do louder for him and not so loud for me. There are more features than I can list that this system is capable of. My favorite is the monitoring. This way if my dad is ill I can allow him the comfort of his bed but still be able to keep check on him. Wonderful quality and I would def buy from this company again.

Need help
Good morning we bought this intercom in 2024. The power inlet on the back is floating in the machine and the machine is not getting power to it. Is there anything you can do either repair it or replace it. Thank you.

QNIGLO Intercoms Wireless for Home uses FRS frequencies
QNIGLO Intercoms Wireless for Home. This is a nice little unit, if you want a base station type FRS radio. I got multiple neighbors on multiple channels, so the range is pretty good. Easy to use. Press a button for a channel, and set a transmit frequency with a switch. I wanted to use this for a house intercom, but do not want my infirm mother broadcasting to the neighbors that she needs to go to the bathroom. Otherwise it would be great, and would work with FRS handheld radios. Great unit. Gave it a 4 star due to lack of privacy frequencies.

Awesome product
Living next door to my mother who’s up there in age, this has been a lifesaver! Literally!! Works great and would definitely buy again!

Disappointing
I got this for our family for Christmas and since setting it up (on frequency A), for each room it has not worked as described. When I try to call a specific room (3 and CALL) the device broadcasts static as a ring tone in the two other rooms and the conversation is heard in all rooms. Sound quality of the conversation in all rooms is very poor, distorted and hard to understand. Unfortunately for me, the window for returns closed 4 days ago as I would return it after multiple attempts to troubleshoot the intercom with the directions.

Perfect for my Clinic!
This little unit is well built and easy to use. I was worried that the signal would be compromised due to some lead lined walls in my x-ray room, but there was no problem at all. The voice transmission is crisp and clear. Well worth the money. I would give is six stars if I could.

Static
Picks up signals from every kid’s walkie-talkie in the neighborhood…..Not what we expected.

Llevo usando 2 semanas y funciona muy bien, es una casa de 350m2 dos niveles y paredes de concreto y la señal se esucha fuerte y claro, prácticamente no necesita instalación solo conectar y una configuración rápida. Hasta ahora todo bien!

The Voice from this wireless device is a bit distorted and broken and this is a Flimsy device . Its okey for home use but not for official inter-departmental communication .

Easy to set up but works like a walkie talkie. Cannot do a two way simultaneous conversation. Only one person at each end can use it at a time. Has a reasonably long range and I set it up one on the ground floor and one on the first floor of my house.. the sound quality could be better. Overall just about serves purpose... Unfortunately there is no better product available in the market
