Just wondering if anyone has any knowledge of Checkpoint Clarity Concept III systems. I work for a large retailer and we were told we could keep our old system but would not receive any tech support. Fast forward to today one of my lovely new guys hit the service button, everything went black so i reset the system and we have video but we cant move the cameras. (even before today the menu button has never worked so we have been unable to set presets ect) Thanks for the help in advance
