Project for hotel security -- might be something for CHA gurus

["Robert L. Bass" <robertlbass@xxxxxxxxxxx>]

I received a call from a hotelier this morning.
He has an interesting problem which I
thought I'd run by the newsgroup.  The hotel
has cameras in all the hallways to protect
guests from intruders (or other guests?).

The cameras are monitored at a security desk.
The problem is security people get bored
staring at a monitor and may not be looking
when something bad happens.

In a hotel hallway the sound level is usually
quite low -- typically >30dB.  They would like
to install a system to detect audio above a
threshold.  They don't want to monitor or
record conversations -- just activate a flashing
light at the security desk if there is a scream or
any noise above a given threshold in the
hallways.

This should be simple enough.  I don't happen
to know of a ready-made hardware device that
would work as the sensor.  If any of you have
done this or something similar I'd appreciate
your suggestions, which I will pass along to
the gentleman.

Thanks in advance.
