IP VIDEO MARGIN TESTER
IPMT-3 - FM SYSTEMS, INC. (FM SYSTEMS, INC.)
The IPMT-3 is a precision attenuator used to test IP video systems to insure that you have an adequate digital signal margin. Digital signal margin is the amount of signal level above the digital cliff that you have in your system to prevent a picture failure from occurring. IP cameras will give you a perfect picture until the network cable loss reaches beyond the minimum allowable signal level and then you suddenly get no picture at all. This effect is called the digital cliff, because like walking off of a cliff, everything is great till you take the last step off the edge and then all is lost.
