Working From Home During COVID-19: How to Monitor Alarms

By Morgana Siggins

August 11, 2020


Many companies are facing serious challenges due to the measures being taken to contain the Coronavirus pandemic. With the stay-at-home order, many employers are being forced to operate and manage their networks completely from home.

If you have a remote gear and processes that are vital for your operations, you need to be able to ensure that your technicians can adapt to the "new normal" and are equipped to do their jobs of monitoring alarms away from their offices.

You might already have a remote monitoring system in place, but now you need to prepare your team to efficiently manage it from their homes. Let's take a look at how your employees can efficiently monitor network alarms from wherever they are.

COVID-19 in the US
In order to maintain your operations up and running and reliable to your end-users, you need to make sure your techs have the tools to continue managing your network monitoring system from home.

It All Starts With a Competent Monitoring System

Downtime, now more than ever, brings a huge financial impact to companies that have networks at remote locations. A competent monitoring system will allow you to keep track of your remote equipment and keep track of your processes.

Having full visibility of your alarm data can help you maintain your mission-critical network running smoothly and at full capacity even during hard times in our society. Of course, priorities are not the same right now, but keeping your business running as close to normal as possible is critical for your employees and clients.

Staying at home is important to maintain the health of your team, but it may not be possible for them to create the exact same space that they have at work. However, an efficient remote monitoring system will have important features that will allow them to keep working productively even from home.

Some of these main features are:

Effective Alerts

Receiving alerts from your monitoring system is your first line of defense. You need detailed and actionable information in order to correct a problem. Unclear and incoherent alerts won't help you prevent not react to network issues.

Your techs should be receiving alerts with sufficient details so they are able to adequately respond. But, they also need to know if the alarm was cleared. This is especially important if they are on their way to a remote site because they can't simply go back and avoid spending time and resources for a condition that doesn't represent an alarm anymore.

Also, the notifications need to reach you wherever you are. Especially if your team is working from home, they need alternatives ways to receive alerts, such as text messages and phone calls. Moreover, if the first person notified isn't able to react to an alarm within a time frame for whatever reason, another tech should be notified and so on - until someone acknowledges it.

Effective alerts will make your team can stay on top of any issue occurring at your remote sites even if they are not working at the office.

Remote monitoring notifications
Without meaningful alarms, you won't know how to properly respond to an emergency on your network in a timely manner.

Remote Control

Being able to remotely monitor your equipment and processes is essential to maintain operational uptime even during a quarantine. But, being able to remotely take action when an issue is detected is critical.

An efficient remote monitoring and control system will provide control relays and serial data ports on top of discrete and analog inputs (which are used to gather monitoring data). Control relays can be used to operate any device that's normally operated by a button or switch.

A control relay is simple contact closure that will either latch or release depending on the command it receives. You can configure your relays to latch when you want, allowing you to remotely open doors, turn on generators, etc.

Now, it's great to be able to remotely operate your equipment, but since your team will be working from home they can be easily distracted and miss an alarm and not manually operate a relay. So, the best systems allow you to pre-program rules for each control relay you have. Whenever these conditions are met, your RTU will automatically latch a control relay.

Your tech will still get a notification but your RTU will correct the situation even if he's not paying attention.

Filter Nuisance Alarms

Now, more than ever, it's important to have your team focused on real alarms.

If your alarm management system is always sending out notifications about events that don't require any action, your technicians will become more and more desensitized to alerts. This will defeat the purpose of having a monitoring system in the first place because your techs might stop taking all alarms into consideration.

These non-essential, recurring notifications are called nuisance alarms. Make sure your monitoring system has the capability of filtering them, so your team can remain productive and can prevent problems from becoming real network threats.

Working from home can already be really distracting. So, make sure your team can remain efficient and focus their efforts on real issues by filtering nuisance alarms.

This functionality of filtering nuisance alarms will include the following features:

  • Alarm qualification
    If problems are self-correcting there's no need to know about them. These alarms can be filtered by using an alarm qualification time that will set how long the alarm condition must be in effect before a notification is sent.
  • No log
    Alarms that are not important don't need to show up in your monitoring screen. It will be recorded in the history file and can be retrieved later for analysis, though.
  • Alarm tagging
    Oscillating alarms can be tagged to stay silent until untagged.
  • Alarm silencing
    In case of oscillating alarms, you can also silence them for a specified period of time.

Don't Forget About Security Features

With employees continuing to work from home, it's a priority for most organizations to ensure that their teams can carry out their tasks securely.

Security concerns was already a big factor for many companies, but now it is even more critical because it involves accessing mission-critical networks from computers at home. It's essential to be able to protect your network against data breaches, hacks, cyberattacks, ransomware threats, and phishing scams.

It's important to remember, though, that even when your staff is not on the clock, your network might still be at risk. So, make sure your remote monitoring system has the latest features and capabilities to ensure the safety of your network information.

Some of these features are:

HTTPS Web Viewing

Since your employees will probably be accessing the monitoring system from ordinary computers and web browsers, your system might be susceptible to viruses and other security holes. In order to protect your mission-critical data and equipment, your monitoring system needs to be secured from open internet access.

Your network master station interface should support secure web access over HTTPS. The HTTPS module supports Hypertext Transfer Protocol over Secure Socket Layer, which is the industry-standard secure web protocol for online sales and financial transactions.

So, when you access your master station's interface using HTTPS, the server establishes a secure connection to your web browser. The data traveling through a secure connection will be encrypted. This way, the information will be protected against eavesdropping and "man in the middle" attacks.

RADIUS Authentication

Remote Authentication Dial-In User Service (RADIUS) technology is an industry best practice for an authentication method. It gives you a way to administer logins to your many different types of devices in one central location.

The RADIUS structure is fairly simple. Multiple RADIUS equipment is connected to a central RADIUS server. This means that every time a device receives a login request (usually through a username and password combination), it will request authentication from the central RADIUS server.

RADIUS security

All the authentication requests are controlled by the central server and not the devices themselves. So, updating user-profiles and access permissions can only be done in one main place. The RADIUS capability gives your network many security advantages, such as:

  • Centralized management
    You'll be able to administer logins from a central RADIUS server. This means that you won't have to worry about updating every single remote device. For example, if an employee leaves the company, you can easily revoke his access rights to all remote devices.
  • Unlimited users
    The RADIUS capability can support virtually as many user logins as you want.
  • Integration with enterprise management
    When your monitoring system devices use the same RADIUS authentication feature as your other important equipment, you'll considerably reduce the complexity of managing all your network.
  • Be aware for all login attempts
    Another important advantage of RADIUS authentication is that you'll know about all access attempts, as well as authorization, and user activities.


The Simple Network Management Protocol (SNMP) is a common communication protocol in many remote monitoring systems. The latest version of SNMP, the SNMPv3, comes with encryption to provide secure transmission of data.

SNMPv3 security comes in 2 main forms:

  1. Authentication
    Authentication ensures that SNMP messages are read-only by the intended recipient. When messages are created, they are given a special key that is based on the EngineID of the device. This key is shared only with the intended recipient and used to receive the message.
  2. Privacy
    Privacy will encrypt messages to make sure they can't be read by unauthorized users. Any intercepted messages will be filled with garbled characters and will be unreadable. This is especially important if your SNMP messages must be routed over the Internet.

NetGuardian RTUs and the T/Mon Master Station follow these and many other security best practices.

A Building Access System Is More Needed Than Ever

Today, social distancing has changed our daily lives and it's safe to say that viruses can spread easily in environments like workplaces. For many companies who are now operating with minimal staffing or fully remote teams, this also means changes to who has building access and how employees are coming and going.

Most companies with the network at remote sites, never had employees working regular shifts at these locations, they simply send teams to fix issues when needed. Even so, there are still security risks that need to be taken into consideration:

  • Access for regular maintenance
  • Updating door schedules
  • Access to clean and disinfect the facility
  • Sharing conventional keys

One way to minimize and even eliminate these problems is by deploying a modern building access system. The DPS Building Access System is a complete electronic access control platform that prioritizes the protection of the user and facility. It has many features and functionalities that not only protect your mission-critical network but also prevents the spread of germs.

remote access control
The Building Access Control System gives network alarm managers the ability to control and regulate door entry access.

The DPS Building Access System offers multiple tools to provide an efficient remote security management system. Here are some of them:

  • Real-time alerts
    You'll get notified at the moment an access event occurs. This includes potential security threats, such as a door propped open or forced open. These alerts will give you peace of mind that your remote sites are secure.
  • Remote unlock
    Any of your entry points can be remotely unlocked from anywhere you are. So, you won't need to be on the premises or send techs on truck rolls when unforeseen situations happen. This is also important in order to avoid contact with keys and other objects that can be contaminated.
  • Door schedules
    Now that many techs are working from home, you can easily navigate you the Building Access Control system's interface and make real-time changes to schedules and permissions for entry doors.
  • Integration
    If you have NetGuardian RTUs and the T/Mon managing equipment and processes, you can easily integrate your Building Access system into your current monitoring network.

We can provide you with a custom access control solution that will give you the flexibility to tailor your system to suit your unique requirements.

The Bottom Line: Remote Monitoring Systems Can Minimize The Impact of COVID-19 in Your Business

Many companies in the US have their employees working from home in order to help prevent the spread of COVID-19. Some of these organizations were hesitant to deploy remote monitoring systems before (many of them thought of monitoring systems just as a cost center), but now they found that they can actually bring many benefits.

Remote monitoring systems have the capacity to offer a safe way for staff to keep managing remote equipment and processes and to successfully maintain network uptime.

Effectively deploying a monitoring system for the first time and being able to successfully work with it is a big task. So, having a system with competent features is essential for your success.
