Camera Server Efficiencies

Our CCTV system has been hacked and pieced together over the last 10 years and became more convoluted than necessary. Now that the Avermedia setup is running, I've been able to simplify things quite a bit. Our system previously used an IR controllable 4-1 composite video switcher to select an active camera based on user input or motion sensors. The automation server would use this feed to take snapshots of the activity. Each camera was also modulated so we could view them on our TVs or Slingbox. Now, the Avermedia records all 4 cameras based on its software motion detection. Also, the software is running full screen as a quad viewer. Since the server is headless, I've connected a VGA to composite video converter and modulated that output. This allows me to remove 3 modulators and the video switcher while still allowing the automation server access to all 4 cameras (albeit smaller views). Finally, an old series 1 TiVo was recording the camera feed continuously and that too got turned off along with its modulator.
