Chamberlain CWA2000: Wireless Motion Alert

Chamberlain is the leader in motion alerts. The CWA2000 is ranked as one of the best motion alerts in the world and comes at an impossible-to-miss price. Before we dig deep into our assessment of the 2000, let’s discuss some of the product’s specifications.

CWA2000 Specifications

  • Weight: 2 pounds
  • Detection Range: 30 feet
  • Base Unit Range: ½ mile
  • Dimensions: 3.44” x 1.87”
  • Expandable: 4 sensor option
  • Alert: Sound


Installing is a breeze. Within 20 minutes, you’ll have everything setup and ready to go. You’ll need 4 AA batteries and a screwdriver to mount the sensor. All that is needed is to screw the mounting plate into the desired location and attach the sensor.

Two switches are provided to change the range of detection from 15 to 30 feet. Sensitivity levels are adjusted with Switch 2 and have high and low levels.

The base unit is simple and will take a DC adapter and 4 batteries for backup. This is self-explanatory with on/off, antenna and volume settings provided. Once installed, you’ll come across several great features that can be adjusted to make your alert even more powerful.

Sound Options

The alerts provided are all done with beeps. You’ll find a volume control right on the base unit, which can be adjusted to a satisfactory level. From my experience, you’ll be able to hear the alert with ease on medium. If you have a home with several floors, you can increase the volume so that you can hear the beeps with ease.

Alert Style

Beeps are provided as the alert style. These are not tones, but beeps that will be rapid or slow depending on how many expansions have been added. The beeps will change depending on how many “zones” have been setup. For example, you will hear one beep for zone one, two beeps for zone two and so on.

Expansion Options

There is the option to add more sensors with a total capacity of up to 4 with the CWA2000. Four accompanying sensors will allow you to monitor the front and back parking lot, garages and a lot more. The best part is that expansion is easy, and you’ll only need one base unit. The alert setting is also intuitive with the beeps provided during an alert matching the zone that is putting off a signal.

Weatherproof, you’ll be able to use this model in virtually any climate as long as you choose batteries that do not freeze in low temperatures. Lithium batteries, for example, can withstand cold up to 20 degrees below 0. If you live in a very cold climate, you’ll want to keep this in mind during the setup process.

The Chamberlain CWA2000 does exceptionally well when it comes to accurate detection. Motion detection can be fickle if the sensitivity is set to high. Deer and larger animals may set off the alarm if you have the high setting active. Adjusting the setting and finding an accurate level of sensitivity is the most difficult part of any motion detection setup.

The CWA2000 gets our seal of approval and is used all across the country. Click here to learn more about this product.
