Works great - especially at this price
Used for entry to office. Handy when office staff is light. Receiving unit plugs into wall outlet - no power problem there. Sending unit w/ infrared motion sensor runs on 9-volt transistor battery. Expect to change battery once or twice per year without any notice. We mounted it to a wall with Velcro tape because it needs to be removed and flipped over to remove battery cover to change battery. Has about 30 different alert sounds, although ding-dong seemed best for us for professional office. If we need more, will buy again.
So easy to use
So easy to use. I put it on the floor near the front door and plug it into the back room. This way I know when some one comes in the front door. Awesome.
Still trying to adjust, but it does go off occasionally with out provocation
Does the job, good range

works good very satisfied
Does not work all the time.
I bought this product based on the good reviews, and I will join the chorus. Good product, a snap to set up and adjust.
Its not good idea for battery operated on this device, battery ran out fast
It will end up in the garbage where it belongs.
Tried multiple places to put this and it works maybe 20% of the time. It actually dings more when people are leaving. Absolute junk. I’d give it zero stars if I could.

We have purchased numerous SadoTech Wireless Motion sensors and receivers and they continue to be sent to us with some defect. We have purchased this product 9 times since September 2015 (through amazon each time) and we continue to have issues.
Had this for 2 years and still works great. Has multiple ring tones
happy with this
Works well, happy with this purchase
This unit has been working perfectly for my garage! Awesome!
These just plain work really really well, good range...almost no real setup required ( Just pick which tone you like and the volume ).Also, battery life is very good...a really good product.
IT WORKS GREAT.
WE USE THIS IN MY OFFICE AT THE FRONT DOOR. IT WORKS GREAT.
Did not last long, the speaker on the receiver unit is dead.
Exactly what I needed for the office!
Plugged the receiver in the back conference room with the motion detector on a table by the front door. Now we dont have to ask anyone to ring the bell!

it works great. one small problem it can be a bit sensitive, I have some palm trees close to where I have it installed, and the blowing palms sets off the doorbell.
Too confusing to buy
Company offers such a mix of products. Bought one thing and found a way better deal on the same product later.
This product works very inconsistently. Very disappointed.
Delivered as Promised
The doorbell sensor works very well for us. We use it inside our house to let us know when my wifes mother is entering the bathroom. We have plugged the receiver in different parts of the house and have not had any problems hearing it. We did have to find a good location for the sensor that was out of the sunlight because of the sensor. The only thing we dont like is that it uses a 9v battery.
Well Made and Easy Set up!
Easy to set up and very happy with how it works! Does the job! Dont see why anyone would have a complaint about it!
very good security product, i use it at home. Very effective
It’s just me

It need a little tweaking but works great now. We know when someone is coming close to our front door.
Great product at a great price I used it for my restaurant so this alerts us when customers come in.. Awesome. Thanks Chuck
My dog cannot sneak out now.
Item arrived on time and in excellent condition. It seems to be working quite well. Occasionally, when it is hot in the house, it might miss me. Yes, in the house. I am using it, in an upstairs hallway, to detect when my dog leaves or enters the master bedroom. She is small, but it detects her very well. I think she has learned, that she can trigger it to get my attention. It works fine for my intended use. I would recommend this to others.
Works like a charm! Found someone sitting outside my window one night, so I purchased this hoping to be alerted anytime someone gets near. Just wish it came with command strips!!
We could not get this doorbell to chime when someone ...
We could not get this doorbell to chime when someone walked in the door, only once they were inside and then chimed within 6 feet of the thing. just did not work properly. Too late to return once figured it out...my fault on that. Out $30.
Good while it lasted.
I bought this product and loved it for the first few months. It suddenly stoped working so I purchased another asap. It only lasted about 2 months. Im very disappointed.
works great, keeps sneaky children in their rooms!
does the job. has a decent range to it as well
Great for stores
We use it in a store I manage. The issue before was the door would go off from the wind. After a little research I found this one and it works great.No more running to the door for customers that are not there.

Better than expected
I only just got this announcer so I couldnt tell about its long term reliability; however, I can tell its fit and finish is excellent, setting it up is a cinch, just plug in the receiver and set the sender in a wall with the hardware supplied. I simply put it in a shelf near the garage door, no mounting necessary, and it works like a charm.The receivers sound if of good quality, does not sound cheap, and the choice of sounds is endless, even piano music from well known and famous composers.I like it and wouldnt hesitate to recommend it, nice product at a great price.
doesnt work at all. Amazon took it off and said the product was having problems.
Way too many false alarms. I spent hours trying to adjust it, but still too many false alarms.
Ding dong, ding dong
This device saved us allot of time to focus on the customers. They can be greeted as soon as they walk in.No more surprise, we know when to expect someone now.So many chimes to choose from. We settled on a typical ring. From the purchase to the shipping and handling went smoothly.
They stand behind their product!!!
Awesome product and awesome company.....I had my motion sensor for about 6 months and for some reason it stop working. I emailed the company and they sent out a new one fast! Will definitely be buying more products from this company.
Richard L. C.
Pros: many different ring types and variable noise level.Clean and easy to use.Cons: the effective range of use is nowhere near what it states.Overall it does what I want to do I just had to adjust my range of use.

Placed at door to warn if dog wanted to come in. Placed high pointed down. Did not work for dog, only worked 1 of 5 tries as I (63). tried to trigger it."
Product as described. Works well.
Works correctly sometimes them other times just keeps ringing then other times doesnt ring at all.
Great Motion Sensor Alert Device!
Wonderful product!I use this as a motion sensor alert and I had to do an adjustment for the sensitivity, but after that it works like a charm!This product met all my expectations so far, by doing what its suppose to do!It gave me the piece of mind that I needed... :-) Ty!

ordered this wireless motion sensor doorbell but got the wrong product received just regular wireless doorbell instead.but decide to keep it to avoid return shipping fee. product good got 50 something sound use for my mom to call in case she need someone. work fine.
Exceptional alarm for the price. I especially like that there are so many alarm tones from which to select and several loud/soft settings. I would devinitely buy this item again.
Stopped working after only several uses
I would use this for my job when I was the only one there at night and it was perfect, very loud (volume is adjustable) and clear, and alerted me when someone walked in my store, did its job. After only a couple uses though, the sensor and receiver stopped communicating, they both still work on their own, the receiver chimes when I click the volume button and the sensors light still flashes red when I walk by it, but they arent working together anymore. Antennae is all the way up and they arent far from each other at all, so I dont know what the problem is.

motion sensor doorbell
Nice product, just didnt fulfill my needs.
I really liked all of the options in the sound category of this item. The ease of installation was also well designed. My only objection was that it is not weatherproof. I missed that part when I ordered it. So, I gave it to my brother to use on his porch as an entry notifier. It works well for him.

Purchased item January 16. Sometimes it worked and most times it did not. We spent more time moving it to try different places in our store and even changing the sensitivity. Even paid anhandyman person to help us try and figure it out. Today it just quit working. Decided to contact seller to return and replace only to find out return window closed. Very dissapointing.
Great doorbell.easy install. I actually use it to alert my sleepwalking husband when hes raiding the refrigerator.
works well with necessary adjustments
solid product, perfected through trial and error when it comes to placement and sensitivity. ring tone is loud and clear and works well for front desk area.
Got it for work as we had an annoying sounding alert for customers previously. This is much more pleasant and am very happy with the product.
Did not do as advertised. I returned it.
Had to return it
I had to return it... didnt work more than a 4 foot distance :(
I love this doorbell! (Had it for a year so far)
I love this doorbell! Funny to say I love it, but I do; especially for the price. Ive had it for one year now. It is trustworthy and always goes off when I (or someone) walk through the range. For us, it had more than a 4-foot detection area. It was easy to install and it was easy to test and see that it was working. I agree about many of the chimes being annoying - We use the Ding dong ding dong" (doorbell-sounding one). Its a pleasant chime and has been no problem to just use that one from the start. The volume ranges from decently loud to really loud. We use the quietest setting (decently loud) and it awakens me from sleep. ALSO I like how it "pauses" a while before chiming again. For example you walk through the detection area and it chimes immediately. But then if you keep walking around that area it waits several seconds before chiming again. So its not like this constant "ding-dong" - its reasonably periodic. In summary yeah weird -- I love the functionality of this product."
Easy to set up and works great. Just wish the range on the bell was better through walls.
Works great for our store. Pretty good range and very loud when at max power.
stopped working same day
stopped working within an hourno power on receiver
works like a charm . so far so good . it is loud enough to hear incoming customer from distance i love it .
THIS IS MY 2D PURCHASE OF THIS DOORBELL-ONE FOR FRONT DOOR-ONE FOR BACK. WORKS GREATT.
This product was shipped quickly and worked exactly as described. This is a great bell for my work place. We are alerted when any one comes in the door.
Worked for awhile then false alarms, Then quit.
Too difficult to set up
Too difficult to set up. Traffic on the street would ring the bell.
We are pleased with this sensor Doorbell
We are pleased with this sensor Doorbell, ~ my husband even extended its sensitivity by attaching a wire to its antenna which he threaded alongside top of our front door. ~ price is good for its features and well probably be ordering a second one soon. ~ thanks ! = A+++
Bought for my business, seems to work well. Very sensitive to motion, had to put a piece of cardboard (Like a blinder) on the reception desk side so it wouldnt chime if someone was working at the desk.
I LOVE THEM!
cant beat the price for the quality you get with these doorbells. I LOVE THEM!
Would like this one much better if on/off switch was on ...
This was a replacement for one I had for 15 years. Would like this one much better if on/off switch was on the receiver instead of the part that is outside. Annoying to have to go out to shut it off when not needed.
Works well with reservations
The Sado Tech wireless door bell system works perfectly but with a couple minor hicups. It does reach as far as it says with both the push buttons and the motion sensor. I have it working at about 300 feet. Now for the hicups. The white receiver does not play all the same sounds the gray receiver does. So depending on what you select it may not ring the same in each room. The biggest disappointment is the window/door transmitters only transmit about 60 feet. So I cant get them to trigger the the alarms from my outside gates to my house or to my garage which is about a 150 feet away. The motion sensor does not work well outside since it triggers every few minutes no matter how you place it even with the sensitivity turned all the way down. Inside they work perfectly and all in all I am happy with the system. Very easy to set up.
All A. M.
Lots of types of alarms. Sensor can be adjusted for sensitivity.
It states it is 433mhz but it is not interfeered with and does not interfer with my other similar alarm that is 433mhz made by 1byone". The sadotech has an easilt removable cover on the sensor which allows you to adjust the delay time between alerts and also sensitivity. The delay seems to be a choice of either 15 seconds or 30 seconds. WOuld be nice if had a 5 second and 60 second option.I have the sensor outside about 50 feet from receiver which is inside. There are three 2x6 walls between them. I have the antenna all the way down (inserted in sensor) and there is no problem with signal.receiver/alarm has a button for loudness and there is at least 4 levels of voluum. It also has too numerous to count sounds. Soome as simple as a single bong and some actual song tunes. Some of which are Christmas tumes. A VERY nice aspect is if you unplug the receiver it will have the same settings when you plug it back in.the blue light on receiver only lights up when alarm/alert activated. i.e. making noise. The red light on sensor lights up when sensor is triggered. It lights up for 1-2 seconds. It is not super obvious in day. At night it gets your attention. You can easily tape over the light if you wish and it will not affect the way the system works."
Works when it wants to, not reliable
Did not work. Ever.
works really well
Not a good door bell it goes off and on to easy.
what a deal !!!! thanks WORKS GREAT
Great easy to use product
Great easy to use product
Wont work inside the mail box even with the antenna outside.
I wanted to like this. My mailbox is about 300 ft away. I found it triggered reliably from the mailbox while holding it. So, I first tried to put it inside the box and drilled a hole in the top for the antenna. It would trigger but would not sound the alarm. Next I tried mounting in a clear plastic box on the backside of the mailbox. I and cut a hole in both the plastic and metal mailbox so the sensor could see through the box. Again it would trigger but no sound was heard at the house. Next I mounted it under the mailbox with the antenna pointing down. Again nothing. Next I put it beside the mailbox on a pole. It did work when I walked by it but it would not trigger when I drove the car to the mailbox. Problem 1. I read that this is an IR sensor, so Im guessing it has to see body heat to trigger the sensor. 2nd problem I think the metal box grounds out the signal. Even when I just set the sensor on top of the box it would not trigger the house sensor. So I have to return it. I can attest that it does work from greater than 300 ft though.
graet stuff easy to instal .....thank you dany
Great use for puppy waiting to go outside!
This device really helped us know when our puppy was waiting at the door to go out. Otherwise we couldnt see it was behind us.
Great function. Lots of ring/sound choices.
Easy set up; works perfectly!!
34 years I’ve been needing something like this.I set this up today and wowzer!! It worked right out of the box and has saved me so much time going to the other room to see if someone has come early or late or not at all for scheduled appointments. And also alerted me to the property owner coming in today.I received a very nice email today from the seller with a user manual and a phone number if I should need any help.As you can tell, I am very happy with my purchase. Thank you to the seller for making this available at such a reasonable price!!
Works in the garage!
This works perfectly for what I want. I have placed it in the garage and when the garage door opens it alerts me that someone has come home. If I leave the garage door open it can reach all the way to the street and alerts me to cars passing by. The volume ranges from fairly low to VERY loud. I wish there was more in the middle but I leave it on the lowest setting so it does not wake my SO when I leave in the morning and the alarm goes off.It is annoying that your sound/volume selection is not saved if you need to unplug it however my preferred noise is the fourth down so its not too much of a hassle.Overall: Great price, does exactly what it says.
I am very impressed with this unit. It works well. I was not sure if it would meet my needs, but it did. I would recommend it to another business person. I have a store front and my office is in back of the store. I am made aware of anyone coming through the store or leaving.
Works well, just as advertised

Soooooo simple to install/use. Beats my old X10 (aka Activehome) setup by a mile. The range of the RF surprised me, as the detector is in one building and the alarm in another and has worked flawlessly from day one. Also, the range of choices for the chime, bell, etc. is phenomenal ... you can do just a simple ding dong, or entertain yourself with the multitude of other choices (the lone rangeer one is TOTALLY COOL). Gotta find more locations to need these and get more!!!

I bought this product about a couple months ago and it is still working great! The motion sensor is sensitive and the alarms can be adjusted to different sounds and sound level.
Works great in my salon. Totally love it
Installation is very easy, but it does work when it wants to. The sensor also seems to need sometime to be able to detect for second time. When there is another person come in short amount of time, it doesnt respond. sometime it doesnt respond at all. I am not sure if this is the spec or defective. I set up about 12-15 a part, and there is a glass window between. It doesnt respond every time... I will keep it because I dont want to hustle returning.
Sensitive to tree motion and leaves blowing by
So-so. Reacts to every leaf that blows by. Trees moving in wind set it off. Would not recommend if you have trees or pets that might cross its path. If those problems dont effect you it works well and is loud and clear wherever you choose to plug in the receiver. We dont use it.

Not a good product.
The product arrived late. On reading the instructions, it stated not for outdoor use but listed as a doorbell. This is very misleading as it is listed as a doorbell. I can not get the doorbell" to work properly. It does not ring when someone crosses in front of it or rings sporadically. The sensitivity has been adjusted with no affect and if it does ring it is delayed.This product does not work as advertised!"

Very please with the doorbell, works great. We use it in our retail store as an alert when a customer walks in or out. Would recommend this to all small businesses.
I have moved it inside the entry way onto the show floor it has been working better, about 90 per...
I have had this about a week. I need this to notify me that I have people coming in the front door as I am a craftsman and while working dont notice that I have someone waiting on me. The front door is located on the opposite end of a show floor that is about 90 feet away from where I work. When I place it in the entry way it works about 10 percent of the time, usually as the customer is leaving. I have moved it inside the entry way onto the show floor it has been working better, about 90 percent but it also goes off for customers that are already in the store that are looking at merchandise. Annoying. I have replaced the battery, changed the position of the sensor to several different high, low and in between, because I really want it to work. But I am debating at this point as to whether I should return it. The entry way is double door glass enclosed, but somehow the glass is messing with the transmitted signal. So, the 500 foot boasted range must be referring to completely unobstructed. Very sad it isnt working as expected
Did not work. No customer support. Do not buy!
Does the Job.
We use this in our retail store to know when customers are walking in. I especially love the 30 second delay so we arent getting a continuous beep when customers are standing in the doorway or moving back and forth as they tend to do...The volume & tone are both adjustable and we have the receiver pretty dang far from the motion detector with zero problems :
Pros and cons- overall a good product.
I bought this to replace a door chime from 1978-- so its automatically better than what we had. But there are a few small downsides to consider. Here are my pros and cons.Pros:-has several different tones to choose from and four different volumes ranging from not very loud to VERY LOUD. We use the very loud setting and have it in a room that is not occupied, but the chime can be heard in the whole office.-the chime part plugs into the wall. So no need for batteries on this part.-the product is modern designed and wont look very tacky set up anywhere.-motion detector is battery operated (9v) so there arent any wires.-convenient on/off switch on the motion detector to turn off the system without having to unplug anything or having to reset the chime.-distance between the chime and the motion detector is 50 ft so it can be plugged into various places to suit the user.Cons:-when choosing your chime tone, if you cycle past what you want you have to keep going to get back to it or unplug the chime and start the tones over.-if the power goes out the chime will reset and you will have to program your chime back to the desired tone and volume.-the motion detector has a wide range of detection so sometimes will pick up unwanted activity if not placed properly.-the motion detector also has a delay. I havent figured it out but it seems like if someone walks in and 10 seconds later someone walks in directly behind them the second entry will not sound the chime.-the antenna on the motion detector is not the prettiest (but I assume it is necessary for the 50ft range. But depending on placement, it could impede the range if you cant raise the antenna.This is my honest review. Overall I do like the chime and it works well in our small office.
