Picture freezes up in Vanguard when motion detection is activated or not

[craigakagravy]

Any help out there?  Everytime that I use the motion detection the picture will freeze.  I have four cams, but only using one for motion detection.  Can it be software?  From what I have read it doesn't sound like Vanguard is something I should have installed.  Also, the picture is freezing up without even using motion detection.  Not sure what I can do here.  Is there any options?  Thanks alot.  Craig in Ohio
