PHYSEN Wireless Door Motion Sensor Alarm,Door Open Chime Detect Alert, Home Security Door Entry Chime with 1 Motion Sensor and 1 Receiver,400ft Range,52 Chimes,4 Volume Levels,Build in LED Indicators

I recently purchased 4 Physen receivers and 3 different types of Physenwireless transmitter (motion detector, window/door sensor, push button).All are used in a two-story house within a range of approximately 100 ft.All devices work as advertised.Each receiver has 4 different volume levels (none totally silent) and lightsup when activated. Each receiver offers some 52 different ring tones(bells, chimes, melodies). Each ring tone can be sampled on YouTube. Simplysearch for "Physen CW Door Bell Ringtones". The only way to select aspecific ring tone is to cycle through them, looking for the sound desired.This is a bit awkward. A nice feature would be a number system permittingeach ring tone to be located directly using a unique number.Each transmitter can easily be programmed to play one of the ring toneson one or more of the receivers. Each receiver can be set to play adifferent ring tone based on the signal received from a specific transmitter.Overall, this product is readily extensible, since each type of transmitterworks with each receiver.The one feature that could be improved might be the sensitivity of the motiondetector to detect motion at a wider range. At close range, it works fine.

At my wife's restaurant there are only two people and at times both need to be in the kitchen. This chimes in the kitchen each time the door is opened insuring they have someone in the front of the restaurant. Saves time and increased their safety knowing someone has entered the restaurant. Best money I've spent there. They as most of these could stand some work on the chimes, but a door bell chime is what they needed and it has one unlike the other one I am stuck with.

We live in the country and it’s always nice to know when someone is walking up to the door. This door chime works every single time. It has different volume levels and tones; even plays music if you want! It is wireless but you have to plug the receiver into the wall in order for it to work. Overall it’s a good product for $25.

Our church was looking for a way for our secretary to know that someone was in the church when she was working in the office, This quiet doorbell placed in the office (and sensor placed near the outside door) works great.

This unit has a multitude of sounds to chose from when monitoring for movement. Unfortunately, no simple single beep. The next simplest sound is a two tone chime. We've gotten used to to the chime, but with so many choices, one would think a simple single tone would have been included. Otherwise, works well, and doesn't go off with every flying leaf.

Worked for three weeks then started working sporadically. Worked 25% of the time, and then five week later stopped working altogether. Even changed the batteries and still doesn't work. Find a more reliable product. This was great when it did work, but not it's useless and it's too late to return it.

It works very well, and works without fail 99% of the time. It has a very wide sensor range that triggers slightly too often in areas further than the doorway. I spent about an hour adjusting it as best as possible, but it reaches about a 10-15' radius from a 15' ceiling.Very audible and excellentt for the price.

I am giving it a 2 stars for coming in on time, but this equipment does not want to stop chiming. I may have gotten a bad equipment. I tried everything that is written on the instruction manual, but I could not seem to get it working properly. It wont detect motion but it goes off every few seconds. It's just frustrating for me.It says that it is paired right out of the box but it doesn't seem to work properly.I could not get a hold of the company that is why I am writing this review. I was glad to see the good reviews but, I can't give a good one on this. Right now I think it is junk.
