Full Disclosure and Disclaimer: To the best of my knowledge at the time of this writing, I do not know anyone that works for the Chamberlain company or for Amazon.com, nor do I hold any stock in either one of those companies. I also will not receive payment of any kind for this review. The views expressed here are only from my own experience and testing. Your results with this product may be different.
For the past several weeks, I have been trying out different types of wireless motion detectors to be used at my Mother's home. I was looking for something that was inexpensive (as far as motion alert systems go), easy to install, easy to use, could be moved to another location if needed/wanted without it being complicated, didn't give off too many false alerts, and one that would be functional in case of a power outage. That was a very "tall order" I know, but I actually have found something that meets all that criteria.
The Chamberlain Wireless Motion Alert CWA2000 system seems to be exactly what I was looking for. At the time of this writing the base and one (1) sensor costs $39.28 on Amazon.com. You are able to add up to 7 more sensors (for a total of 8 sensors) on the same base at the cost of $29.32 per sensors. If you live in a cold climate like I do, you will want to use lithium batteries instead of alkaline batteries in the sensors if they are to be used outdoors, The base unit uses both electricity and batteries as a back up. The base unit can be kept up to a 1/2 mile away from the sensors and will still work very well.
I have also tried much more expensive motion alert systems, (some that were up to $500 for just the base and one sensor) but in my humble opinion, over all they didn't perform any better than what the Chamberlain does. I have read some reviews on this product that claimed it was hard to hear the alert when it would go off, but I didn't have that problem at all. In fact, I had to turn the volume down quite a bit.
The only down side that I have found with this product is that the sensor needs to be hip high or higher. That is because a person's stride might be wide enough to allow someone to one walk right by the sensor without the sensor detecting the motion. But that is easily resolved by placing the sensor up a little higher.
I am passing this information along and what I have found because I know that several of my subscribers are looking for something along this line due to the increase in crime. If nothing else this product does give a lot of peace of mine. Thanks for reading and visiting my blog. :-)
