Environmental monitoring options

[cabenth at gmail.com (eric clark)]

I'd like to ask the list what products people are using to monitor their
environments. By this I'm referring to datacenters, and other equipment.
Temperature, humidity, airflow, cameras, dry contacts, door sensors, leak
detection, all that sort of thing.

I've used Netbotz in the past. Looking to see what else is out there that
people like.

Thanks
