I would envisage in-house customer engineers or those associated with specialist security firms wishing to install these new systems would have the expertise to fit them now. That is the triumph inherent in providing a system that can be adapted to attach to and control any number of devices/sensors. The wiring/connection is the easy part (for those who do that sort of thing) but making the control interface easy to operate by just about anyone able to walk and chew gum simultaneously, as this is, is the smart part. Perhaps a few more in the market may finally tweak to the fact that TZL really is as good as most of the share holders (not all) believe.
