Hi,  
  
I am new here and looking for something which I hope exists, probably basic even! 
  
I wish to install a HD IP PTZ on each corner of a building so they can constantly sweep righ/left and left/right continuously to detect moving objects and then zoom in and track until the object leaves the cameras view and then retrn to the sweep mode. 
  
I would also like to setup the cameras to be in sync thus ensuring no black or dead spots, this means if a camera leaves the sweep and returns it needs to re-sync with the other moving cameras. 
  
I am planning to use a QNAP NVR as this is compatible with the Control4 system being installed but this can be changed to other NVR or platform if needed. 
  
If what I propose isnt possible or simply flawed I would consider other alternatives such as the fisheye and PTZ combinations i have seen if they are reliable and perform well? 
  
I have attached a PDF showing the setup from a aerial perspective along with the specifications of the PTZ. 
  
Thanks in advance and I apologize for the long post.
