We have not had any false alarms.
Sally Mae
It is great to know someone is coming up my driveway before they get to the house.
Laura Haskin
The alarm on the high setting was not loud enough for me to hear in the next room.

I have read several negative reviews about the Chamberlain CWA2000 Wireless Motion Alert system... many of which compared it to its predecessor. I have used the former version with success for 3 years and I was disappointed that it had been discontinued and replaced with this model and that it was not compatible with my old sensors.
Despite the negative reviews -mostly about the low volume of the base station - I decided to purchase one anyhow because the price is so attractive. I figured I would send it back if I wasn't satisfied. It works fine! The old model allowed the base station to be put on mute for one hour. That feature no longer exists - but the sound can be raised or lowered which helps compensate if someone will be working in one of my remote buildings - tripping the sensor repeatedly - which is when we would use the mute feature. Another new feature that I haven't tested yet is that this new version can handle 8 sensors, each with a unique signal [1 beep - 8 beeps]. Its predecessor could only be trained for 4.
I live in a heavily wooded & hilly location with a very long driveway and several outbuildings that need to be protected. This unit will work for 300-400+ yards dependably. The volume is adjustable and is certainly audible all over my house. The earlier units may have been "fixed" because the base station makes plenty of noise now. I suggest buying several base stations and training them all to the same codes [1 beep for driveway, 2 beeps for shed, 3 beeps for outside the garage, 4 beeps for inside the garage, etc.]. I also strongly recommend that you use lithium batteries for the sensors if they are to be used in a location where the temperature goes below 20degrees F. Alkaline batteries freeze around 15 degrees F; lithium's are good to 20 below zero F.

I don't normally write reviews, but have to stick up for this product. I bought it along with 2 additional sensors 1 1/2 years ago. It's the best investment I've made in a long time. I've been monitoring my driveway, deck, and basement door. I installed the unit in my master bedroom so it wakes us up if triggered. However, we can easily hear it downstairs as long as we don't have really loud music on. There is one beep for sensor 1, two beeps for sensor 2 and so on. Some people might miss the "one beep" from a very far away or excessive external noise, but I installed my most active sensor (driveway) to be sensor 3 (3 beeps) and never miss hearing it. The 4 AA batteries I originally installed are still working! Yes, it will take 4-5 minutes to open up the units and change them, but you'll only need to do it ever 1-2 years and there protected from weather inside the sensor. I highly recommended if you value knowing when something is on certain parts of your property and don't mind being woken up occasionally if you have deer, cats, or other animals that wander at night. I live in a suburban neighborhood and already caught one person walking up my driveway at 4AM trying to break into our cars. I've also enjoyed hearing the beeps knowing when someone is coming up the driveway during the day.

I have owned/installed 7 of these systems at my childrens/my home over the last 15 years, all the way back to the original "Reporter" models.

The original Reporter had circuit boards made in the USA (printed on the boards). They all worked great at far distances. I could easily get a full 1300 feet(unobstructed view)of reception even though they only claimed they were good for 1000'.

About 4-5 years ago Chamberlain company bought Reporter. Unfortunatly this is the same time I had to replace my old/original units (from weather/sun fatigue) of approx 10 years usage. The new units I ordered had the same transmitter (field unit) case cover and a slightly differnt receiver (house unit) cover, but the circuit bords were all made in China (printed right on the boards). These units were terrible. I tested 6 of these transmitters, each with an unobstructed view. The maximum reception I could get was 400' on one and only 150'/200' on all the other transmitters. All new fresh/expensive Li-Ion batteries here too, so no low voltage excuses. Quality control of these circuit boars is the big issue here!!!! So I ended up moving them very close to my house. I have lived with those for several years (not good).

I just received 2 new sets of this new CWA2000 model on 8-24-2012. I tested both systems side by side on the exact same spot I have used for the last 15 years. These work even better than the original Reporter units. Upon inspection I see the units were assembled in Mexico on 7-25-21012 (yes, just 1 month ago!), so they are the latest/freshest you can get. No made in stamp on the boards, just on the outer plastic receiver case. With only a 1 month duration between assembly and delivery, it is very likely these circuit boards are made in the USA or Mexico.

Your level of satisfaction with this product will be based solely on your application.

First, let me explain how this product works.

This product senses motion between two different temperatures. The outside air and anything warmer or cooler than that air. So, thankfully swaying tree branches do not trigger it.

If you're looking to be alerted to humans or animals, this product does that very well.

If you're looking to be alerted to vehicles (which is why I bought it) there will be some limitations...

Because the vehicles exterior is usually the same temperature as the outside, it's more difficult to detect a vehicle.

The trick is to point the unit so it sees the rear of the vehicle as it passes. Hopefully it glimpses the tailpipe which is always hot.

On a dry day, detection is good. Rainy days, snowy days and some cold days where the vehicles sheetmetal is exposed to those elements thus, the same temperature as the outside, detection is almost non-existant.

So, depending on your application... It's a good unit based on what you expect it to do.

If you want to flawlessly detect vehicles, consider an alert system with a sensor that detects metal rather than movement.

Good Shopping!
