Hello, 
  
I finally took the plunge and purchased a avtech DVR 4ch with networking .  It's connected to two fixed cameras and a PTZ unit.  I set everything up via my main computer and it works great 
  
Got it all work and communicating spot on but how in the hell do i set the presets on the DVR for the ptz control?    I go to video web server E on my computer,  Go to the PTZ controller button and select the PTZ camera.  I can move it about, zoom etc  I can even press AUTO and it swings left to right ok.  I have got 16 Preset buttons and would like to preset  certain positions etc so I haven't got to faff about tooo much when looking about. 
  
anyone have any ideas?
