What a great product. I bought a set of six and doorbell unit. Thanks for the review.

Great video and thank you for taking the time. Is it easy to add additional units to the system if you decide to buy two 4-packs? I'm guessing that it is as you were able to integrat the door bell monitor. Just thought I'd make sure. Thank you in advance!

Great video

Can I use just the outdoor doorbell unit with these intercoms? I like the ring feature of the handhelds, but don’t like the handhelds for my in-laws as they will just lose them and not charge them. Prefer the wall mounted unit. I’m considering buying a 2pack of the 666, and a single outdoor bell, if it can chime the 666. Thanks for your very helpful videos!

I can transmit from Wuloo to my programmed Baofeng on correct frequency but cannot answer from the handheld? No PL codes chosen. Just simple channel 462.725

Hello, can you monitor multiple rooms at once? If I have 3 youngsters in three different rooms I want to be able to listen in on all of them throughout the night.

Mines didn’t come with a remote control, am I still able to monitor sound from another intercom in my kitchen over my intercom in my mancave?

How does GROUP function work? Does it simultaneously transmit to all 10 channels or does it use a common pre-defined frequency between all wuloo intercom units?

Is the communication via this intercom system secure? Or speech can be heard from any walkie talkie or SDR if it in range?

Do you have to hit call? Can't just press 1 then "talk" and it will broadcast what you say into the room?

I have a question for you: I am considering purchasing both the doorbell and intercom units. However, I read a note from the owner's manual that states although these units are compatible with each other, the outside doorbell unit cannot summon or ring the intercom base. Can you confirm this and elaborate your experience? If you do not have this experience, would you try it and provide your feedback? Thanks...

I programmed ch1 freq into a Baofeng uv-5r with no results. Any suggestions?

Do you know how this model differs from the WL-888 model? Great video, by the way.

Mine works intermittently. I can call them and they can respond. Then an hour later I can call them but then I cannot hear their response. Any suggestions?

whenever i try to change the channel to a different one, it never stays and goes back to one, i lost the instructions, so how can i fix this?

Can you speak to someone without calling them? As in can you just select the required channel and then click the talk button to speak directly?

Sounds like this is using digital transmissions and not analog. Can this be listened to by radio scanner or SDR?

If you have a walkie-talkie, will this work with intercom system?

So how many extension can it hold

Can you provide 12 no instruments in this system
