I’ve notice that base doesn’t cover cameras mounted behind base. Is this correct? So to get camera to work in typical rectangular house i need to have 2 bases, which is a bit crap?
The base broadcasts pretty omnidirectionally. It has several antennas inside that allow it to cover well in any direction. That said, if you are having issues in one direction, try turning the Homebase slightly to see if the coverage improves. I have had 2 Homebases before, but through careful siting of the Homebase I now only use 1. I have cameras and sensors completely around my house and out in a shed in back and they all work fine with a single centrally located Homebase. Its far more likely that your interior construction might be causing your coverage issues.
