Wireless Alert System,
April 18, 2008
"I installed the alarm along the driveway to alert me of anyone coming or going. The line of sight between the receiver and transmitter is obstructed by a small patch of woods/brush, but it works great. Total distance is approx. 500' . No more surprise visits or people at my door without me already knowing they are coming. I would recommend this product to all."

Driveway alert system,
April 17, 2008
"Installed two months ago and has worked flawlessly. The distance from my driveway entry sensor to the location in the house for the receiver is only about 200 ft but the signal appears to function each time on people or vehicles. The post on which the sensor is mounted is about 20 ft from a right angle roadway where many vehicles pass so I used the angle feature on the mounting to focus it away from that road to keep out unwanted alerts. Also it is set to the lower sensitivity mode. Additionally I added a 12v digital counter to the auxilliary contacts so I could tell when there is an entry when we are not in the house and it will increment by one on each entry--not that we would necessarily know who it was but still helpful."

Not worth a dime !!,

"Don't believe a word in the advertisement. This thing works when it wants to, but mostly not at all. I messed with the range and sensitivity to point I'm sick of it. No amount of adjustments gets this thing to work as stated in the ads. Northern should do it's customers a favor and drop this from inventory, it's nothing but an aggravation."

"It doesn't have the advertised range, but I still like it! My two indoor units and three outdoor units pass thru 3 block walls at a range of 250 feet. Batteries last two years. Very reliable."

"I mounted my motion detector at the end of my driveway which is roughly 400 feet from my house. The receiver was unable to pick up a signal at that distance. I ended up having to move my motion detector within 100 feet of my house before the receiver would pick up the signal. Another problem is that the motion detector is not consistent. Sometimes cars go by and the alarm on the receiver does not go off. To be fair, perhaps mine had some kind of defect, but I would probably look at other options next time."

Hit or Miss,
October 19, 2009
"I hung the transmitter on a tree down by the entrance to my driveway, then put the receiver up in my shop, about 200' away with line of sight. The only thing between the two is the wall of my shop, which is standard frame construction with vinyl siding. It started out working pretty regular, but degraded in a couple of weeks to hit or miss. It will see my wife's Chevy HHR leaving, but not coming back. Ditto for my father's Rav4. Yet it sees the kid next door on the garden tractor on just about every pass he mows, up to about 40' away, and sometimes sees tri-axles on the main road, even though it's pointed away. Drives me frickin' crazy. I've played with position and sensitivity till the cows come home, to no avail. Save your money."
