Bring Peace of Mind
The monitoring function is exceptionally well-suited as an aid for children or the elderly, enabling them to seek assistance quickly and effortlessly. Rather than constantly running up and down the stairs, you can better take care of your loved ones.
The monitoring function is designed to operate continuously without any time restrictions. It never automatically shuts off, providing you and your family with complete peace of mind and a sense of security.

Do the intercoms need pairing to work? If I add extra units to the existing system, do they need pairing?
No. They’re pre-configured at the factory—just plug in the power and use them right out of the box. Adding extra intercoms also does not require pairing. It’s very user-friendly for first-time intercom users.
Why can only one side be heard while the other side can’t hear?
Your environment is too noisy, causing interference. For two-way (hands-free) talk, use a relatively quiet place (e.g., a room, living room, or garage). If you need to use it on a noisy jobsite, press and hold “Talk” while speaking for communication
The call volume seems a bit low?
The other person is likely too far from the microphone. We recommend speaking about 30 cm (12 in) from the mic for better pickup and clearer sound.
Can the intercom use batteries?
No. The intercom has no battery compartment.
However, we include a charging cable and adapter with each unit, so you can plug it in and use it right out of the box.
What is the Monitor function? How do I use it?
The monitor feature must be started from the device being monitored, so you can’t listen to someone proactively. This protects privacy.
For example, unit 1 must press the Monitor button first, then select channel 2. Only then can 2 start monitoring 1

Easy and effective
Works great, and set up couldn’t be easier.I bought this to install a “plug-and-play” intercom system so I didn’t have to yell at my kids from across the house anymore. It works exactly as I need it to. I started with just two, and bought two more for additional rooms – they all automatically connect as soon as you plug them in. I have them all linked so when you speak through one, it transmits through all of the others simultaneously, but you can program it to only transmit to a single unit at a time using a simple and easy channel system. (There are nine channel numbers, so my guess is that is the maximum number of units that can be linked together, but I haven’t fact-checked that.) The sound quality on the transmission is great – clear and loud (which is great for children and the elderly). It has different settings where you can either transmit by holding a button down (like a walkie-talkie) or press an “on” button once that transmits continuously (like a telephone). What’s more, all of this versatility is truly optional and not complicated. Like I said, you can just plug it in and it’s ready to go, literally no set up required.They are built simple and compact, the size of a small book, are light-weight and their appearance doesn’t stand out any more than any of our other electronic devices.The one possible down-side is that the material feels very light-weight, so it is possible that it might break easier than one would like. However, my kids have already (of course) thrown them around a bit and they held up fine. Also, even if they end up being more fragile than is ideal, they still are worth the very reasonable price.

Works better than expected. Very satisfied.
Wasn’t expecting much for the price, but these turned out to be a pretty nice set of intercoms. Voices are clear, and the quality of the units is good. Each unit comes with it’s own cord and power block, so I am very happy with that. We have a large house, so I ordered a set of 4, but you can get 2, 4, or 6 units and assign each one a station. Set-up was as easy as plugging each unit in and assigning each one a number by pressing that number on the keypad.Okay, I’ve read some poor reviews that I would like to address now.1. These ARE Dual VOX. The trick is to assign each unit a number by pressing and holding a different number for each unit. When you talk, press the number of the unit you want to talk through, and then wait for someone to pick up. For example, if you are at station #1 and want to speak to someone at station #2, press the button with the “2” on it, and then wait for someone to press the “talk” button. You can then talk easily without pushing the talk button.2. Voices are clear when speaking, but keep in mind that these are VOX units, and there is a slight delay when speaking, so wait a second before responding.3. The “MONITORED” feature is NOT for having a conversation.Watch the video in the Amazon description for more information about other functions of these intercoms.
Older 1 than I thought –
get ready to spend some time using it and understanding the point by point instructions.
good working product but we’re still trying to get it working. Its a slow learning experience for an 88 yr old. Gets very frustrating. It could use step by step instructions. Other than that it appears to be well worth the money.

Extremely simple to use, good for the elderly
I bought these intercoms as my elderly parents had just moved into a larger house. My dad has limited mobility, and my mom was worried about being too far away from him in the house. We just set these up last week, and they are exactly what we needed in this situation. Using the intercoms is as simple as could be – you just hit the group call button, it rings the rest of the intercoms, and then from any of the other intercoms you can answer the call and start a conversation. It’s clear when a call is active, and also really simple to end a call. My measure is really whether my elderly mom can learn how to do it, and she absolutely did.The intercoms also allow for a bit more complex functionality, like setting them on different channels and allowing 1:1 calls between intercoms. We don’t need that for our use case, so I don’t know how easy it is to set up. But for what we needed, these were perfect – easy to set up and learn, reliable, and the audio came through very clearly.
Amazon Customer –
Full duplex, work great! Highly recommended
These are fantastic. Full duplex, hands free talking. For those reviews stating they are not full duplex, they are certainly mistaken and not using the correctly. These intercom units look nicer than so many other out there too. Crystal clear and they are perfect to put in my office, kids rooms, etc. so nobody needs to yell to communicate. Highly recommended, took no time at all to plum them in and start using them. Virtually 1 button to set them up and assign a different number to each unit. Better price than other 4-packs as well.

Not full duplex + annoying beep
These just okay, but they are a bit annoying. The unit beeps every time you press a button, and there doesn’t seem to be any way to turn it off. This is especially driving my wife crazy. I was also hoping to use them in duplex mode, but they are not full duplex as advertised. Full duplex means you can both listen and talk to each other at the same time. What these do is they activate the transmit mode when you speak loud enough, and then the other person can’t talk at the same time. The problem is you have to talk in a pretty strong and loud voice in order for it to transmit. Even when she was sitting right by it, my wife talked in a normal voice, but it wasn’t loud enough to make the unit transmit in the “duplex” mode. If you want to use these like an old-fashioned intercom by pressing the talk button, and don’t mind getting beeped at, they should work pretty well.

Seems OK for our outside annexe about 100 ft from the house. Range gets considerably restricted if there are windows

Muy fácil de configurar solo me falta ver si tienen ese Alcance que dice en una casa de dos pisos desde la cosita a todos los cuartos
Reliable Evaluation –
I was excited to try this but was dismayed by its abysmal performance. Major Communication issue with this device/tech; either one sided voice or no voice on either side is what I experienced 90% of the times. I will have to box this and look for alternatives. A lot of money was lost as this was imported.
