• Composite Video - The Complete video signal
consisting of the video information, the sync, pulse, and
threshold reference signal.
• DSL - Deep Scattering layer; Digital Subscriber Line
• Ethernet - A system for connecting a number of com-
puter systems to form a local area network, with proto-

simultaneous transmission by two or more systems.
• Exception - Suspicious cash register or ATM trans-

so they can be mixed and or switched through other

• Ground Loop - An unwanted electric current path
in a circuit resulting in stray signals or interference,
occurring , e.g., when two earthed points in the same
circuit have different potentials.
• Inventory Shrinkage - Is the loss of products be-
tween point of manufacture to purchase from supplier
