Review on π Enhanced CWA2000 Chamberlain Wireless Motion Alert by Matt Louis
Might give you some advance warning.
I was trying to find a device that actually transmits in the specified kilometer range. The maximum distance we were able to receive a signal from the transmitter to the base station is about 750 feet. It was a disappointment. We also have a Guardian system (rated for half a mile) that provides about 600 feet. Our driveway is nearly 1,000 feet long and lined with trees, so I understand not getting range, but accept the claimed range with a grain of salt.
- Easy to use
- Short instructions
