Product Description

Amazon.com Product Description

Sometimes you just forget to close the garage door. But if "sometimes" is closer to "usually" for you, you may run the risk of having your garage emptied out by opportunistic passers-by, and you will certainly pay more to heat your house. Chamberlain's Clicker Garage Door Monitor helps you minimize the likelihood that you'll leave the biggest door in your house open. The device mounts easily without tools to your garage door via a Velcro strip; if your door is open, the sensor sends a signal to the monitor, causing a red light to flash. The monitor may be plugged in anywhere in your house where you're likely to notice the flashing light. Depending on your garage-door habits, this device could help prevent theft and lower your heating bills. Includes lithium battery.--Josh Dettweiler

From the Manufacturer

Did you close the garage door after you put the mower away? Go check now... You back? All good? Phew! But for next time, save yourself an unnecessary trip out to the alley with Chamberlain's garage door monitor. The garage door is big, and tough to forget to close. But, when you do, it's very likely that all those valuable tools, bikes, skis, and whatever else you keep in there won't be there by the time you realize what you've done. Chamberlain's garage door monitor lets you know if the garage door is opened or closed without the trip out to the alley in the middle of the night. The system installs easily with no tools. Just set up the sensor on the door, and set up the monitor in any room in the house. A flashing red light on the monitor means the door is open.

4.0 out of 5 stars Works as advertised!, December 7, 2007

My garage is a separate building about 15' away from my house, so I needed something to tell me if I left the door open. I'm using this about 100' away from the transmitter - a bit too much for it. It worked fine at first, but then would lose signal on occasion. I noticed that the receiver had an antenna but the transmitter didn't. I opened up the transmitter and found the antenna "loop" - I simply soldered on a piece of wire of the appropriate length (this uses 390mhz, so I used a 1/2 wave length of wire, which is 14.4 inches). Works perfectly now!

4.0 out of 5 stars Worth the money spent, May 24, 2006

It isn't the most robust device, but it was worth the money spent on it. The sensor attaches to the garage door with sticky back velcro. This makes it easy to remove to change the battery. I put it on the top of the door, so it will indicate open as soon as possible. Range seems sufficient. The only unknown is how long the transmitter battery will last. It uses a nickel sized lithium cell.

Update 2006-10-25: I still don't know about the longevity of the transmitter battery (still going strong), but I have loved this unit for the past few months. It has become a little "confused" two times over the last 6 months. It would indicate open, when the garage wasn't. I unplugged the base unit and immediately plugged it in and all was fine. I would purchase this again and wish I had done so sooner.

4.0 out of 5 stars No problems, June 28, 2006

I received this item three weeks ago. Installation was easy and the unit worked as specified. I didn't have a problem with any distance, however my garage door is only about 50 feet away from the base unit.

You do have to plug the base unit into a wall outlet and it has a slightly bulky transformer. I didn't know that when I purchased it. I thought both units were battery operated. So you can't just hang the base unit up on a wall in the house somewhere.

Overall I gave it four stars.
