CCTV and BOSCH Plena Systems

CCTV and PA systems are common equipment in any modern building, they are often taken for granted. 

Common they maybe, I bet you rarely see where the other end of it go. Here's how it  looks like; 

BOSCH PLENA SYSTEM

 Bosch Plena system is one of the easiest to install, I their routers use external Audio Amplifiers via XLR cable. The processor is can be easily configured using a laptop and it has a feature which can tell you whether the system is properly configured, cables and all.
Zone speaker wires are connected to the router and processor via phoenix connectors, no soldering needed. Call are connected via CAT5/CAT6 and they can looped for several locations where call station and keypads are needed.

The image on the right shows the back of the rack.
The processor, router, tuner and amplifiers are all mounted with 1 RU in between.
