Product Overview

The Wireless Alert Sensor is a Passive Infra-Red (PIR) Motion Sensor that detects movement of people and vehicles, while allowing small animals to pass through undetected. Each sensor has its own unique ID, for a secure radio link. The base station (not provided) can learn the signals of up to 8 sensors. The base station gives a single beep for the first sensor that is programmed, a double beep for the second, and so on. Additionally, multiple base stations can work with the same sensor to sound in different places.

  • Transmits signal to base station up to a half-mile away
  • Detects motion up to 30 feet away with wide 120 degree coverage
  • Adjustable sensitivity controls help prevent false alerts
  • Wireless, weatherproof design makes it portable for use inside or out

Answer: 
Hello Chuck. I see the item connected to this question is a model CWPIR. This add-on sensor is the only sensor that is compatible as an add-on to our model CWA2000 Wireless Motion Alert System and would be the one that you need. If the other sensor you found is a different part number, it is not compatible.

Answer: 
Hello Frenger - The base station that this sensor is compatible to is the CWA2000. I have included a link to the base station so you can see if it matches yours. If it is not the same base station, we do not have a sensor that works with the older sensor. http://www.homedepot.com/p/Chamberlain-Motion-Sensor-with-Wireless-Motion-Alert-CWA2000/202046712?keyword=cwa2000

Answer: 
Hello Happy, and thank you for your question. Yes, this sensor is compatible with the CWA2000 base station. One base station can have up to 4 sensors programmed, and the alarm tones that it produces will indicate which sensor has detected motion.

Rated 3.6 out of 5 by 8 reviewers.
Rated 4.0 out of 5.0 by Added security Purchased two additional sensors for my existing system to monitor my adjacent lot. Both sensors required some tree pruning and brush clearing but are now working great. August 22, 2016
Rated 4.0 out of 5.0 by Wireless Motion Alert System the add sensor is very good and the battery life is also very good the only thing is that some times th device goes to sleep and it does not warn you about intrusion also another thing is that the opening were the sensor is recessed some spiders make a nest there needs to have a glass window built in to avoid spiders from building a nest.

Rated 4.0 out of 5.0 by CHAMBERLAIN MOTION ALERT IF YOU USE MORE THAN ONE WITH THE BASE UNIT, IT IS A LOT OF WORK TO GET THEM IN NOTICE ORDER, SO YOU CAN TELL WHICH AREA HAS MOVEMENT. August 2, 2016
Rated 5.0 out of 5.0 by Armadillo Detection in Yard I live in rural southeast Georgia and have a bad situation with armadillos tearing up my grass in search of grubs. I bought the Chamberlain motion alert system and have had much success detecting these destructive critters in the wee hours of the morning. I mounted the sensor(s) on a flat metal stake about 1 foot off the ground in front of locations where they are digging (I call them "hotspots"). When the alarm goes off at night, I get up, grab flashlight and .22 rifle with red laser sight and take care of business. Its a very effective way of controlling our armadillo population.

Rated 3.0 out of 5.0 by Continuous Alarms I have used these products for many years . This year I ordered a new base and one sensor. The base linked up with my original sensors and with the new sensor however the new sensor gives continuous alarms. I had to remove it from its location and place one of my old sensors in its place.

Rated 4.0 out of 5.0 by motion system We really like our system. We have no problems with it. February 25, 2015
Rated 2.0 out of 5.0 by Driveway Monitoring I have purchase the Driveway monitoring system with sensor plus added 3 additional sensors. I've found that I can be 10 ft away from any unit and if I move very slowly, I can get past the sensor without tripping the unit. After the unit trips once, it will not trip again for at lease 60 seconds. If one were to move very quickly through the monitoring area, the sensor doesn't trigger. I've been able to cross the path of the sensor in about 25 feet with normal walking speed and not trigger the sensors. Would be nice to have a third switch to select reset time to be fast or slow for re-trigger speed along with another for super sensitive and or a better processor to better identify IR from non to even the beginning of some instead of waiting till the one reaches the other side of the sensor before a trigger. Maybe you went too far the other way to reduce the false positives. September 2, 2014
Rated 3.0 out of 5.0 by False Positives I purchased the base+sensor, plus 3 more sensors. I was hoping that I could set them up along my long driveway to know if someone was approaching or if someone were in front of the garage which is not visible from indoors. I set up 2 sensors in the evening and all seemed well. At noon the next day, the sensors were continuously alerting, so I moved them. It was better for a while but then the continuous alarm started up again until I shut off the base. It seems that they are picking up signals from my gravel drive or grass or something when the sun hits. I did not experiment to find the farthest distance, but I confirmed that they will transmit at least 1/4 mile without perfect conditions, so that is comforting. I found that if I drive my side-by-side UTV (like an ATV) past the sensor at 15 mph, the sensor does not report. I will see if the lower sensitivity setting helps my false positives, otherwise I don't know what to do. I wish there were a different sensor option that would detect vehicles with metal so I did not have to depend on motion for some sensors, and could put those alongside or under the driveway.
