Wireless PIR Motion Sensor Detector Security Alarm Chime,Shop Store Office Home Front Door Entry Welcome Doorbell,Mailbox Alert, Garage Driveway Alarm,with Night Light (1 Receiver and 2 PIR Detectors)

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.

We have a loud embroidery and screen printing shop. We set this motion sensor up by the front door and put the two receivers near the loud machinery so we can hear if someone walks in. It has been wonderful! I literally used to always glance at the door non stop to make sure I hadn't missed someone walking in. No more anxious glances....we can just work and know exactly when someone enters.

We have bought two of these for our businesses. Easy set up, work well

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?

Worked great in the store to notify when anyone came in. We used the hello welcome as it was very inviting.

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.

Sensor response is very fast and sensitive, the trigger is basically no delay, recommended!

Works well placed over door. Only alarms when someone is close enough to touch the door
