We are  now working with CE Telecom Network Services Inc.  They are a provider of Network Services, Network Cabling, Video Surveillance, Remote Monitoring,  and other office security applications.   Check out  http://ce-tele.com , there are several links to videos that explain the services that your office might need, and some interesting links to camera demos that allow you to try the PTZ cameras by Advidia and Panasonic.  PG Technology still does the non-regulated functions like Managed Services (Full Service Help Desk 7x24, telecom services, including new Gigabit Internet connections), and CE Telecom Network Services Inc. does network build out and regulated Texas State Private Security activities (Security Cameras).   Stop by and take a look at VMS  (Video Management System)  With the purchase of an Advidia camera the VMS software is free.  A quote off of their website:
"Enterprise VMS Features at No Extra Cost

Each Advidia camera comes bundled with a free copy of Video Insight Enterprise Video Management Software, which includes: Health Monitor, Video Wall, Automated Failover, Unlimited Clients and Users, Active Directory / LDAP Integration – all at no extra cost." 

Check out the features then compare! They also have VMS training available, a two day class, web based videos, and if needed on-site training for a group.  The software is very powerful and allows you to use all of the features of their cameras. It also scales very well for the Enterprise environment.
