SoftPLC Helps Stop Intruders
An ISP and mobile phone service provider has five
separate equipment locations in the city, connected by fiber.
They use SoftPLC to monitor/control environmental and security
conditions (burglar alarm, fire alarm, temperature, UPS status, water
Environmental information/alarms are sent from the
SoftPLC's to a central SCADA system at the main location.
A web cam feed is also provided, primarily for security
company was concerned that control room operators
would become immune to a continuous video feed and possibly miss an
event. Using the SoftPLC Programmer's toolkit, the user developed
a custom routine that runs in the SoftPLC to implement SNMP
traps. Thus, the SoftPLC systems can trigger live camera images
only upon an
intrusion alarm or detection of motion.
I/O control, communications and the ability for the user to customize
the web cam interface, SoftPLC was the perfect choice to make this
application easy to implement and maintain.
