To get a sense of what the W.H.E.N. AVH21 A/V hub is capable of, you have to do the math. A single AVH21 can distribute digital audio and control signals to up to eight separate rooms. Feed up to six video zones. Display the output of up to seven security cameras. Trigger two electronic door locks. And uplink to two additional, three total, additional hubs, each of which can do all of the above. But the AVH21 isn’t just about quantity. First and foremost, it’s about quality. Which is why the AVH21 employs proprietary digital signal transfer technologies to minimize signal loss, even over the longest runs.
