Customer Questions & Answers

If I have two garage doors, do I need two sets? Will they transmit on the same frequency?

I'm wondering if I need one monitor and two sensors. Will the monitor blink red if one door is open?
Asked by: handyGC
Yes, I have two sensors for two doors, they won't interfere each other

What is the range in feet for the wireless connection?

The garage is on the first floor, our condo unit is on the fourth floor, stucco and wire construction.
Asked by: Robert
Robert, Sorry I don't know the answer. Mine is about 30' away from the transmitter to the receiver through typical 2x4 construction. Suggest that 100' feet line-of-site might be a good estimate between transmitter and reciever. Suggest you buy it, open carefully, try it, and return if it does not work. Good luck.

What Home Depot store has this in stock?

Online says out of stock. If you search stores, you can search only by zip code, which requires you to know all the zip codes in your city or in the country. No way to find if it is available anywhere. Very frustrating. Does Home Depot even carry this anymore?
Asked by: Gary
You can order online and send it to your local Home Depot without paying shipping charges

can this be used with any brand door opener?

Asked by: kaytee
Hello, and thank you for your question. This system operates independently of the garage door opener, and can therefore be used on any garage door.

Does this Camberlain Garage door sensor also have a sound or alarm to indicate the door is open?

Asked by: Anonymous
No. The operator does not alarm as to door position.

Yes. I have two transmitters and one receiver and if either door is open the receiver blinks red to indicate one of the two doors is open.

Does the garage door have to be perfectly horizontal in the up position for sensor to function?

I have not yet received my alarm but noticed that the upper sections of my garage door are not completely horizontal. Very close but only the second door section from the bottom is level. This seems to be the way the door was designed because the roller brackets seem to cause the tilt of the various sections. Can I still place the sensor at the top of the door or should I place it on the most horizontal section even if that is toward the bottom?
Asked by: Richard22
Almost, if the sensor is mounted flat against the door. Suggest mounting the sensor tilted down a little to work earlier.

Garage Door Monitor is rated 4.2 out of 5 by 81.
Rated 2 out of 5 by from Doesn't last This unit worked fine for a couple of years but now it just flashes red/green constantly. Resetting doesn't help.

Rated 5 out of 5 by from Great Security for Obscured Garage Doors The garage door monitor by Chamberlain takes minutes to install and gives you the piece of mind you want when you can't see if your garage door is closed or not. For those of us that walk into the house and then think "Did I close the garage door?", this is your solution. The small transmitter mounts quickly and easily to any garage door with the included adhesive "hook and loop" strip. Make sure to install the transmitter with the curved side facing the bottom of the door so the internal motion switch can operate properly. The battery is included, it's a lithium coin cell size 2032. The receiver mounts to any wall using a small screw. It mounts just like a smoke detector. Adjust the flexible wire antenna into an L position to guarantee it can pick up the signal from the transmitter. The receiver has a plug in power pack, so you'll need to install it within six feet of an outlet. Once installed and the receiver is plugged in it automatically picks up the signal from it's matched transmitter. When the door is closed, the light on the receiver base stays solid green. When the door is open, the receiver base will flash red. It takes just a moment to see if you closed your door. My garage is over 50 feet from the receiver and I've had no signal issues. We've had temps near zero lately and it still worked perfectly. I'm glad I got this. No more wandering outside at night to see if I in fact closed the door. One look at the light gives me my answer without ever leaving the house.

Rated 5 out of 5 by from A Senior Confident I've own this product before smartphones were popular. So for those seniors without smartphones and after coming in from a beautiful day, with this garage door monitor, you'll know for sure the garage door is closed – from any room in the house. Excellent

Rated 1 out of 5 by from Poor Design Great idea, poor design. The sensors work great on the garage doors, but don't transmit very far. This only works in the room closest to the garage. This was not designed by anyone mindful of interior design. The cord and the wire antenna come out of the top, so have to be routed down and around. The power outlet is black, not white. Do you know of any interior walls in America that are complemented by a black, dangling cord? The wire antenna works fine for a garage door opener mechanism, but looks terrible in a house. The LED lights are dim. Too bad this is the only manufacturer who makes such a product that I know of.

Rated 5 out of 5 by from Perfect for the job This works exactly as you would hope. It doesn't care what kind of opener you have, you wouldn't even need an opener. One part mounts on the door, very easily. The other has a power unit that plugs in somewhere in your house where you can see it, and hangs on the wall. GREEN = Closed, Flashing RED = Open.

Rated 5 out of 5 by from garage monitor this is the only thing that I found that is reliable and works great. My doors are no longer left open for critters to come in at night. thank you

Rated 5 out of 5 by from Very useful and reliable Purchased and installed within minutes of arrival. After 33 years in a home without a garage, moved into retirement community in a ranch home with garage. Second day, left the garage door open over night. Installed this unit and no more worries. Advises me of door status, silently and definitively. Well worth the small cost.

Rated 5 out of 5 by from Does the job I purchased it to do. The monitor works as intended, installation a breeze. Mounting the transmitter on the garage door was a no brainer, just follow the instructions, same with the monitor. I have to go outside to enter my small garage, therefore the garage door and my house exit are parallel. Now with the monitor, I can look at it to see if I need to open the door, or if I forgot to close it after coming into the house. Home Depot delivery was prompt.
