Ah, and on that: http://www.netbotz.com/ (rackmountable and wall- or 
camera-mountable Temp, RH, air speed, door contact, camera, and 
external sensors: all web/SNMP addressable w/email alerts available). 
I've got four WallBotz 310 units, in server rooms, wiring closets, 
and cluster rooms. And the cluster room has a thermostat monitored 
24x7 by our Physical Plant. Braces and belt, when that much hardware 
is on the line.
