Sensor works great.

Wow, the sensor is so sensitiveGreat product

I paired the sensor to the receiver but it will not work if the sensor is more than 15 ft from the receiver and it has to be inside my house

Sensor is so sensitive that it is set off numerous times on a windy day.

Would like a replacement sensor

This sensor is junk.

Love this infrared alert sensor and receivers.

That first sensor paired immediately and works perfectly, even managing to transmit a 100 feet and through the metal mailbox!The second unit, though, has to be paired manually

Sensor is super accurate !

The sensor is very difficult to get positioned correctly

This seems to be an issue with cheaper motion sensors, but I'm not sure what causes them to loose their detection capability.

The sensor pairs well with the base at a fair distance and with moderate obstacles (house floors and walls)

i have set up 3 sensors and they work perfect at night

Sensor works well

The sensor works great.

Pros: the sensor and receiver work well from one bedroom to another; even in the dark of night with hardly any

This sensor is amazing

But, after a few hours, the sensors seem to no longer work or the chime loses its memory that it sync'd with the sensors.

Also, compared to other motion detection alarm that I have evaluated, IMO, I find the 1byone unit offers more flexibility and option in terms of volume control and tunes; the sensor is quite portable with decent range, so I can move it to various location as needed.

I have other smart sensors that notify my phone, but nothing seems available to give me a simple audible chime like these do for this price.

Unreliable sensor.

It comes with 2 passive IR sensors and a receiver that you plug into the wall.

I only discovered just how much of a piece of junk this sensor was when my car was broken into with $2k+ worth of tools stolen

this sensor is really sensitive works great

this sensor is really sensitive works great

However, the street is about twice that distance and the sensor detects large objects on the street (the garbage truck, for example).

During the day, the base is unplugged so we don't hear it but know the sensor is working because it lights up.

Sensor reads all the way to the street so it won't work for me because every car that goes down the road causes bell to go off

We're working on a more 'sturdy' holder so the sensor isn't so sensitive

the sensor and receiver are maybe 80 feet away from each other with a few walls in between.works great, the sensor does take batteries but i haven't needed to replace them in the 6 months or so since Ive had it.

Purchase product, one sensor defective and would not work.

These are great wireless sensors

I think I'll go for a more expensive door sensor next time.

I like the setup, very easy, but the sensor really has a hard time working properly sometimes.

We placed the sensor about 50 feet away from the transmitter and it won't work

Another issue is that sensors are pretty sensitive, so a cat or squirrel or leaf that passes across the sensor also triggers it.

The box serves the purpose of protecting the sensor from UV rays as

May not have quite the same range, but was easier to setup, can be expanded with multiple motion detectors, has a decent remote interface (easy to see blue activity light on sensor), seems to have better battery life (sensor), has better range on loudness settings and of course allows many tunes to choose

The sensors work alternately and intermittently but never as designed

The receiver has now quit working and that means the sensor for the most part is useless.
