Wireless Split Doorbell PIR Motion Sensor Detector Security Driveway Alarm Chime for Shop Store Office Home Front Door Entry Welcome Doorbell,Mailbox Alert Door Bell(1 Receiver and 1 PIR Detector)

We have a severely autistic 14 year old son. Unfortunately, he likes to put his hands in the toilet after he uses the bathroom. This has been a huge mess and a huge stress. I found this product when searching safety products for people with alzheimer's because I couldn't find any autism-related products. I placed the sensor on top of the toilet (didn't install it in case I want to move it) and set the alarm to the Beethoven chime setting. It works perfectly and was VERY easy to set up. Now I can check the monitor every time the chime sounds and see what he's up to. It has helped tremendously because I can catch any shenanigans early and stop him before it gets worse. For instance, I heard the chime yesterday and found that he was dunking his stuffed animal in the toilet for some reason. I was able to run up there, stop him, and tell him no. I would highly recommend this effective and easy to set up sensor detector.

This works great. I have one of the two sensor/transmitters mounted on the front porch overhang, pointing down to the front porch. The receiver/chime I placed upstairs. We can’t hear our downstairs doorbell from upstairs, so this alerts us to the presence of someone on the porch, even if they’re not pressing the doorbell, such as for online deliveries.And it works fine, these are all battery powered so it is easy to move the receiver to any room we want at any time. I don’t have a current use for the second sensor unit, but I keep it handy in case I need extra security for some room such as when company comes over; I can just set it down anywhere.You can select from 36 different ringtones and four different volume levels. There are several modes you can select from, and to avoid having to look up the four different control buttons on the receiver I put Dymo labels on it for “MODE”, “ON/OFF”, “SONGS”, and “VOLUME”. I didn’t want to hit the MODE button by mistake and have to dig out the instructions to reset that function.When you turn the receiver ON or OFF it gives short distinct ringtones to let you know you turned it ON or OFF. I would have preferred an LED to provide the ON/OFF status. As it is, if I can’t remember if the receiver is ON or OFF I have to click the ON/OFF button which toggles the state and gives me the ringtone for the new on/off status.

System works great but the second sensor I would like to have a different sound for the back door of the business. Can anybody help me out?

Only complaint is that it’s range may be a bit limited but not bad. Does what its intended to do.

They are easy to set up, and they are definitely loud enough, could use one more setting for low. However, they are very sensitive to reflections. Our business is on a busy road and the reflection off the cars would make it go off randomly. We ended up turning it off.

If you have dogs like mine they will go to the back door and wait to be let out but won’t make much noise to let you know. If you don’t notice or get there in time then you will have an accident to clean up. This is a great motion sensor to put at the base of your door to let you know when your puppies need to go potty. The only downsides would be the sensor sensitivity and volume. If my dogs walk by the door or feel like sunbathing it will go off and can be annoying. Also the volume doesn’t go very low so it could wake up my kids at night. Solution it has a light only option and you can just turn it off if it gets annoying. I hope this helps.

We are very happy with this unit. We set one up in our mailbox so we know for sure when it has come to avoid repeated trips down a long driveway. It works every time.
