72 reviews for Wireless PIR Motion Sensor Detector Security Alarm Chime (SF20R)
This system is not only very affordable, considering it comes with 2 transmitters, but also works just as we needed it to for alerting us when our 94 year old father gets out of bed during the night and needs assistance. We use the lowest volume bell chime for whomever is on night shift for getting up. The range of the broadcast from the transmitter is ideal in that it is narrow enough(using vertically) so as not to detect any motion but as soon as he sits at the edge of his bed. If a broader range becomes necessary, we can easily rotate to the horizontal position. I really like that there is an option for battery operation or usb. We attached the transmitter with an adhesive Command sticker to the side of a multi plug at the outlet that has a USB port, making installation quite simple. The transmitter ends up being about calf height and we positioned it to diagonally pick up from near where he sits on the edge of the bed to the foot of the bed, catching another route if he gets confused and decides to head toward steps. It is obvious there are multiple mounting options. Very pleased with this product.

This is great! The motion detection is perfect, I love the distance range and the ability to swivel. I use it to cover my hallway to keep track of my sneaky kid at night. The only thing I wish were different would be the alarm sound. The store chime is the best option for us, but it goes of twice each time. Once is sufficient, making twice annoying. The volume selection is great as well.

I work security and often the clients property is vast enough that while inspecting one section you may miss movement on another. I decided to try this and found it so easy to use and effective that I will certainly buy more units to spread around the property and assign different sounds to different locations. I can easily carry the receiver and get alert while walking the property... I’ll update my review after further usage and see how they hold up.

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.
