[labnetwork] Paging system

[John Nicholson]

Iulian,

	We have a "ring down" phone installed by the clean room entry that
rings a phone in the relatively quiet interior access corridor as soon
it's picked up. Anyone can use the interior phone to make local calls
(i.e. my office) or LD calls if they have an access code and the
interior phone can also be called from any other phone. The facility is
small enough (~1500 SF) so that the phone can be heard from any of the
user bays despite the pump and HVAC sound level. The only drawback to
this arrangement is that our number is one digit off from the campus
Financial Aid office and I get too many wrong number calls from parents
who should be wearing their reading glasses.
	The initial plan was to use the AXIS networked cameras in the clean
room bays as an intercom with video via my office computer. However when
I asked for equipment recommendations from the campus police (they were
the only ones with video monitoring on campus at that time), I was told
to contact the campus legal office before implementing any audio/video
monitoring. After six months or so I finally got the legal opinion that
having the ability to control an audio feed without the lab users
knowledge from my office violated Massachusetts privacy laws (even if
lab users signed a consent form). Cameras were installed without
intercom ability. A video intercom may not have this restriction in your
location (and it may no longer be an issue in Massachusetts).
	In one of our chase areas, any intercom without some kind of noise
cancellation would be difficult due to pump noise.

P.S. My initial post - I've been following the list postings with great
interest for a while so I thought I'd make an attempt to contribute.
