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.Read more ›
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.
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.Read more ›
