This is the most common Problem we see!  Here are the Possible causes:

1.  Security Eyes Software set to PAL instead of NTSC
2.  PC's Video Card Drivers not installed (Using Default Windows Drivers)
3.  Using Onboard Style (Unsupported) Video Card.
4.  Cameras not getting correct power
5.  Video Cable connection problems

Here are a few tips:
1.  Change the "Video Format" Setting in the main control panel to NTSC then restart the software.
2.  Load the latest Video card drivers from your Display Adapter Manufacturer's Website
3.  Replace onboard style video card with an AGP or PCIe Video card that meets Security Eyes system requirements
4.  Ensure that the correct polarity and voltage is getting to your cameras.  Cup your hands over an infrared camera to see if the LEDs glow (a good sign the camera is getting power)
5.  Move video cables >2-4 feet away from high-load electrical devices, check for loose connectors, or plug the camera directly into the DVR Card or TV with a short length of cable.

These causes and solutions fix 99% of the blue screen problems that people run into with the Security Eyes Pro DVR Card (Trust us  )
