Sensor Monitor Essentials:

Here's a handy checklist of essential features you should look for in a sensor monitor. Print this checklist out and use it to rate the sensor monitor you're evaluating. If a system can't meet these basic requirements, cross it off your list.

Essential alarm sorting and analysis functions

• Root cause analysis: Finding the underlying cause between alarm cascades can take hours of patient detective work. Look for a system that can automatically correlate repeated combinations of alarms.
• History and trend analysis: Identify problem areas and eliminate recurring problems with a system that keeps a complete alarm history that's exportable for trend analysis.
• Alarm sorting: A large, complex network can create a cascade of alarms. Some are unimportant, but others are critical. Look for a sensor monitor that can automatically sort and prioritize this flood of information for you.
• Nuisance alarm filtering: Even the best NOC staff stops taking alarms seriously if they're bombarded with status alerts, oscillating conditions, and unimportant alarms. Look for a system that filters these out.
• Custom combination alarms: A low battery isn't a serious problem, and neither is a failed generator, but they're pretty serious when the happen at the same time. Look for a sensor monitor that can watch many different alarm inputs and spot critical alarm combinations.

Critical alarm collection and device management functions

• Control relays: Many common site problems, from power outages to high temperature alarms, can be solved by quickly turning on a generator or an air conditioner. Remote operation of site devices is the best way to eliminate unnecessary site visits and it's a lot faster than going in the truck.
• SNMP support and ping alarms: If you're responsible for both telecom and IP equipment, consolidate all your monitoring on one sensor monitor.
• Back-up dial-up reporting: Don't rely on your primary network to bring back alarms. If anything goes wrong with your transport, you'll lose your telemetry data just when you need it the most. Look for a sensor monitor that support dial-up alternate path reporting.
• Multiprotocol support for your existing devices: Make sure your next sensor monitor collects alarms from all your existing devices, including your older legacy gear. You can get rid of all your specialized consoles and monitor your network from one screen.
• Live analog monitoring: You can't adequately monitor battery levels, temperature, and humidity with one-threshold contact closures. Look for a sensor monitor that support for analog inputs, including live monitoring of actual analog values.

Key alarm presentation and notification functions

• Web interface: Everybody knows how to use a Web browser. A Web interface makes sure all your field techs can access your sensor monitor, from any computer from any location.
• Pager and e-mail notifications: Pager and e-mail notifications let your field techs respond to alarms while they're still in the field, speeding repairs and reducing windshield time. Look for a sensor monitor with SMS support, which can send detailed alarm notifications to alpha pagers, cell phones, and PDAs.
• Detailed alarm notifications: Summary "major/minor" alarms don't give you enough information to make dispatch decisions. Look for a sensor monitor that include detailed diagnostic information in each alarm.
• Alarm correction instructions: Detailed instructions included in alarm notifications ensure that system operators, without extra training, will know precisely what to do and who to call if an alarm happens.

"All the sensor monitors I make are backed by my no-risk, money-back guarantee. If you buy my equipment and you're not satisfied for any reason during the first 30 days, simply return it for a full refund. If my product doesn't solve your problem, I don't want you to have it." - Bob Berry, CEO, DPS Telecom
