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.

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.

Rated 5.0 out of 5.0 by Thom 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.

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.

We really like our system. We have no problems with it.

Rated 2.0 out of 5.0 by RCSteve 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.

Rated 3.0 out of 5.0 by WW1955 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.
