2,742 customers mention1,995 positive747 negative

Customers like the quality of the surveillance systems. They mention it works well, is practical, and simple to use. The sensors synchronize and work in harmony. The mounting plate works well and is good value for the money. The units can operate over long distances and through walls with no problems. They never fail to activate the alarm on the base station when triggered.

"...After having it for a while I find it works very well in its intended purpose. It has performed reliably and consistently with no surprises...." Read more

"...The mounting plate worked well, I pre-assembled everything and just screwed the mounting plates directly to trees near the driveway using deck..." Read more

"...I did some research. This model seemed to fit the bill and be reasonably priced ( price has come down since)...." Read more

"...Online research will show that others have encountered sensors with false alarms, which Chamberlain admitted is an issue with some sensors...." Read more

467 customers mention412 positive55 negative

Customers like the ease of setup of the surveillance system. They say the detectors are small and easy to attach to a stake. The instructions are okay if you follow them carefully. They are very easy to train to the base unit, connect to the main base station, and mount. The sensors are easy to learn and the furthest one from the base station is 300 feet. Overall, customers are satisfied with the well thought out design and instructions.

352 customers mention252 positive100 negative

Customers like the range of the surveillance system. They mention that the signal reaches far enough to trigger the monitor in their shop at the back of the house. The sensors work great and have an awesome distance. It transmits very long distances and through walls with no problems. It covers the distance with no problem and has not missed a customer yet. Some like the fact that it is wireless and expandable.

Customers are mixed about the volume of the surveillance system. Some mention that the volume adjustment was just right for their application, and the volume is adequate. However, others say that the beeper is insufficiently loud, has a high pitched squeal, and is not audible from more than 1 room away.

"...The beep when a sensor activates is a long sort of whiny squeal versus a quick chirp, and its a little irritating...." Read more

"...The volume is adequate for me. But I'm surprised it wasn't designed with more available volume. This seems to be the main complaint in reviews...." Read more

"...Great. Then sunset came. It was a bit breezy and was beeping repeatedly for tree shadows that were moving on the driveway??..." Read more

"...Be advised the Chamberlain sensor does not make any sound so if you have a visitor, unwanted or not, they will most likely still be in the area..." Read more

412 customers mention184 positive228 negative

Customers are mixed about the motion detection of the surveillance system. Some mention that it's detecting every vehicle that passes, and it'll randomly detect a person walking by. However, others say that in January 2018, the detection rate fell greatly due to multiple below-freezing days, and the sensors may not detect as well. They also say that the product doesn't have enough detection range, and has trouble detecting cars sometimes.

"...Also I find they don't have enough detection range. If there is rebar in your driveway this could interfere with the detector...." Read more

"...When it is not windy it is 100% accurate. It has great flexibility for adding additional sensors and was relatively inexpensive compared to other..." Read more

"...to the fact that she drives a bit faster and that the receivers can't respond fast enough?..." Read more

"...Its extremely good at detecting humans and animals...." Read more

170 customers mention79 positive91 negative

Customers have mixed opinions about the value of the surveillance system. Some mention it's a great product at a reasonable price, while others say that it'd be better off buying another unit. Some customers also mention that the entire system looks cheap and feels cheap. Overall, opinions are mixed, and it'll be up to individual customers to decide which option is best for them.

"...It is not cheap, but was a better value to me, than ordering separate sensors, which are overpriced.The two new kits came in...." Read more

"...This, combined with the low cost and high mobility of the unit; it comes with multiple methods of mounting and can simply be hand placed if need be,..." Read more

"...And one last thing, the extra transmitters are a bit expensive...." Read more

"...Overall, great value for the price." Read more

151 customers mention58 positive93 negative

Customers are mixed about the battery life of the surveillance system. Some mention that the base unit uses batteries for back up, and the battery feature is nice. However, others say that one week before two of the four batteries were depleted. They also mention that when the batteries get low or really cold, they get an alert every half hour. The main downfall of the product is the lack of battery option.

"...Things you might not like:It needs 8 AA alkaline batteries (4 are optional for receiver backup). But they should last a long time...." Read more

"...Adjustable volume. Receiver has battery backup. It is simple and works.Wish list...." Read more

"...after it kept sounding an alarm every half hour, that my batteries in the receiver were low, not the transmitter!..." Read more

"...The best part about this set up is the remote station also operates off batteries if it's not plugged in, so I could take it with me inside..." Read more

142 customers mention88 positive54 negative

Customers are mixed about the sensitivity of the surveillance systems. Some mention they are very pleased with their sensitivities, the adjustable sensitivity is helpful to detect cars and people, and not small animals. However, others say that it has LOW sensitivity and LOW range settings, and the receivers are not too sensitive and seem to only pick up vehicles.

"...Sensitivity seems fine for my purposes, although sometimes I feel like one given sensor might be slightly more or less sensitive than another...." Read more

"...off all night long... I bought this specifically because it has LOW sensitivity and LOW range settings...." Read more

"...The receivers are not too sensitive and seem to only pick up vehicles, and reasonably large animals like big dogs and deer as long as you have the..." Read more

"...Has adjustable sensitivity to better accommodate your unique requirements...." Read more

I used it for a Uhaul alarm system
5 Stars
I used it for a Uhaul alarm system
I used the Chamberlain as a motion alarm inside my Uhaul truck. I was transporting cross country some very expensive items I did not feel comfortable shipping, and preferred to have my eyes (and ears) on everything the entire time. I stayed in motels where I could have line of sight from my room at all times. The Chamberlain gave me peace of mind b/c I set the motion detector inside the locked cargo box of the truck and had the remote station in my room to alert me. The best part about this set up is the remote station also operates off batteries if it's not plugged in, so I could take it with me inside restaurants or places where I would lose line of sight, bathrooms, etc. The reception is around 1/2 mile but trees, hills, buildings and other things could affect distance so don't expect a full 1/2 mile. The motion sensor runs off batteries only. In extreme cold climates I would suggest batteries designed for cold weather. The information on the ad for this product can be a little confusing in regards to batteries. The receiver station uses 4 AA batteries, or you can just plug it into a wall outlet. The motion sensor if I remember takes 3 AA batteries that last for many months, maybe a year. The home station is pretty small and I could carry it portable inside my jacket pocket running off batteries. Its only like 3-4 inches square with 5 inch antenna. Set up for this product took me less than 5 minutes. You will need a very small phillips head screwdriver to open the back of the motion sensor and install the batteries. TESTING: I used my phone on record function to test the alarm every night during my trip. I would basically put my phone on record next to the receiver in my motel room, go out to the truck, open the cargo door where I had the sensor on the inside, and then go back to my room to listen to the recording. It worked every time. There is a volume level you can set and also a chime or alarm sound. I also used a backup motion alarm designed for a brake caliper of a motorcycle and put that on an outside grab handle of the Uhaul cargo door. At one motel the motorcycle alarm went off at 3am and I could hear it from my room. You have to pretty much bang that alarm pretty good to get it to go off so I knew someone messed with it. On inspection I noticed someone had messed with the lock on my Uhaul b/c I set it a certain way and noticed it was moved. The weather seal on my lock had been opened too. Even if I didn't have the motorcycle motion sensor alarm I am confident the Chamberlain would have also alerted me if they had cut the lock and opened the cargo door (and I was basically 150 feet away). Be advised the Chamberlain sensor does not make any sound so if you have a visitor, unwanted or not, they will most likely still be in the area since only the receiver station sounds an alarm. This Chamberlain was well worth the $50 and is a pretty solid little set up. In my opinion its a sturdy product from a well known established company. Now that my trip is over I plan to install this sensor on the side of my house to alert me when the neighborhood feral cats pay a visit. These feral cats have turned the side of my house into a litterbox and I plan to set up a legal cage trap and be alerted every time I've caught one. I think this Chamberlain would work well for anyone who has valuables stored in their yard, cargo trailers, work trucks, etc. Once I'm done with the cats I will install this on my back patio where I recently caught a homeless guy searching around. He climbed the wall in the middle olf the night, tripped in the dark and made a noise and I heard him and he ran off leaving behind his tweaker backpack full of stolen merch from a local drug store. With the Chamberlain I'll know if he returns (I also have a monitored alarm on the house so I'm not worried). The Chamberlain motion sensor doesn't make an alert sound but it does have a small flashing red LED light I noticed when it detects motion. If you're trying to use it as a stealth detector I guess you could put something on it to cover the red flashing LED light. I hope my review helped.
