There's never an exactly "typical day" for your field techs. They're installing equipment at mountaintop cell sites, driving between substations, responding to after-hours alerts, and often working from locations with limited or no network access.

Despite this, you still need full situational awareness of your network.

That involves real-time alerts, remote control, and the ability to acknowledge alarms (without needing to boot up a laptop or ask/beg IT for VPN credentials).

Unfortunately, many legacy monitoring systems (even those that claim to be "mobile friendly") don't make good on that promise. Some just shoot out vague text messages. Others still expect your techs to remote into a workstation - or worse, require app installs that run in conflict with security policies.

In 2025, that's not actual "mobile NOC monitoring". It's a liability waiting to cost you.

Old-School "Mobile" Tools Just Don't Cut It

Let's walk through what often passes as "mobile NOC support" in some older systems:

• SMS alerts without context. You get a cryptic text: "Alarm #17 at Site 142." That's not enough to act. Is it power? Temperature? Access control? Without details, you're left guessing.
• Limited or no acknowledgment options. Even if you do figure out what the issue is, you still have to remote into a central interface - or worse, drive to the site - to acknowledge the alarm or flip a relay.
• LAN-only communication. Many RTUs still depend entirely on Ethernet. When the site's down, you're completely blind. You might have a bulletproof network at more centrally located sites, but very remote sites often demand a failover channel.
• Firewall holes and security risks. Some solutions require you to punch holes in your network firewall just to get remote access.
• App-based control. Requiring techs to install and maintain apps (and update them constantly) creates friction - and triggers IT red flags.

If you're like many of our clients, this should sound pretty familiar.

This was tolerable in a world where most monitoring happened from desks. But in 2025, when techs are moving around 24/7 and sites are more remote than ever, you can't afford that kind of delay or downtime.

What True Mobile Monitoring Should Look Like

Let's imagine what "good" actually looks like. If you were designing a mobile-first NOC tool from the ground up, it would include:

• 100% Mobile Operation. No reliance on desktops or laptops. You get full control from a phone or tablet browser.
• Clear, Context-Rich Alerts. SMS, voice, and email alerts tell you exactly what's wrong - right now.
• Remote Alarm Acknowledgment. The ability to acknowledge alarms from anywhere, with audit trail logging.
• Remote Relay Control. Power cycle routers, unlock doors, and start generators - right from your phone.
• Firewall-Free Security. HTTPS-based access doesn't require risky firewall holes or app installs.
• LAN-Independent Communication. Alarms continue to report even when LAN or Wi-Fi go down.
• Voice-Based Redundancy. When all else fails, you should still be able to hear the alarm and press a phone key to respond.

If your current setup doesn't deliver on all of these points, it's not fully mobile-ready, which is probably holding you back in various ways.

The Mobile Monitoring Checklist for 2025

Here's a practical checklist you can use when evaluating any mobile-ready monitoring system:

Feature	Must-Have?
1. Full mobile access via browser (no app installs)	Yes
2. SMS, voice, and email alerts with full context	Yes
3. Remote alarm acknowledgment with audit trail	Yes
4. Secure relay control from phone/tablet	Yes
5. No required firewall holes or VPNs	Yes
6. Voice alerting & phone-keypad control	Yes
7. Works without LAN/Wi-Fi (cell-only sites)	Yes

Most vendors will hit 2 or 3 of these. But unless a solution hits every single one, your mobile NOC isn't fully covered.

DPS Clients Are Already Mobile Without Compromise

We've been building mobile-ready monitoring gear long before it was so common - because our clients needed it.

DPS systems have long been deployed in environments where downtime is costly, and physical access is limited or delayed.

That's why every DPS product is designed to be:

• Mobile-first. Our tools don't assume you're sitting in an office.
• Browser-accessible. There are no app stores, no IT headaches, and no updates to manage.
• Connectivity flexible. Whether your site is on LAN, wireless, or completely off-grid - we've got a solution.

T/Mon LNX + Mobile Web Interface: Your NOC in Your Pocket

The T/Mon LNX is the central nervous system of your monitoring infrastructure. With its mobile-optimized web interface, your phone becomes your handheld NOC command center.

From a secure HTTPS connection, you can:

• View real-time alarms (Standing and COS)
• Acknowledge alarms with a single tap
• Monitor color-coded site summaries
• Operate remote relays to reboot routers, unlock doors, or start generators
• Securely log all actions for compliance and review

That means no apps, no installs, and no dependencies. Just open your mobile browser and take action.

Stay Connected Without LAN Using Wireless-Ready NetGuardian RTUs

Many of our most popular RTUs - including the NetGuardian 216 G6 and NetGuardian 832A G6 - are built to keep sending alarms even when your Ethernet or LAN goes down.

They do this by:

• Sending SMS alerts directly to your phone using internal cellular modems
• Delivering voice alerts that speak alarm messages to you over any phone line
• Enabling DTMF control, so you can respond using your keypad - even from a landline

They also monitor critical inputs like:

• Temperature
• Power supply voltage
• Battery levels
• Door contact sensors
• Generator status

With DPS NetGuardians, you won't just get alerted - you'll get useful data that helps you fix the problem faster.

Voice Alerts + DTMF for When Some Things Aren't IP-Based

Smartphones are great, but what if your tech is using a flip phone? Or standing in a Faraday-caged shelter?

Voice alerting with DTMF control is the ultimate backup plan.

When an alarm occurs:

• You'll get a voice call with the alarm message read out loud.
• You can acknowledge it using touch tones.
• You'll receive confirmation instantly.

This isn't optional fluff. It's critical functionality that works even when the newest tech doesn't.

Order Wire + OffNet Calling: Even Without Cell or Ethernet

Let's say your site is extremely remote - no LAN, no cell coverage, and no public telephone access. Most vendors would say: "We can't monitor that site."

We say: "Let's set up Order Wire."

With DPS Order Wire and OffNet calling features, you can:

• Create private voice intercom channels between sites and your NOC
• Use "Hoot N' Holler" broadcast paging to speak to multiple sites at once
• Leverage OffNet jacks to place outbound calls via PSTN or cell gateway

Whether you're operating in the desert, a mountaintop, or underground - you stay connected.

DPS Offers Proven, Battle-Tested Solutions

There are a lot of companies selling "monitoring tools" that tick a few boxes on the spec sheet, but ultimately have limitations.

These tools talk mobile but require apps. They talk about "security" but require extensive firewall holes. They talk about "flexibility" but only support LAN as a connectivity method.

At DPS, we build real tools for real sites.

Our advantage comes from 30+ years of deep engineering and close client collaboration. That gives us:

• Custom-fit solutions, not one-size-fits-all boxes
• US-based engineering & support, from right here at our headquarters in Fresno, CA (and from US-based satellite offices in the event you're in a different time zone)
• Zero-pressure consultations, focused on solving your actual problems
• 30-day money-back guarantee to de-risk your purchase
• Ongoing firmware updates, hardware revision support, and direct-to-engineer phone access

You'll never have to explain to us what a remote RTU does or why your tech needs to acknowledge an alarm from a mountaintop in 30 seconds or less.

We already get it - because we've lived it.

Real Example: Cell-Only Site in Wyoming Still Gets Alarmed in Seconds

A major DPS client in Wyoming has dozens of sites that operate without any wired internet access. Winter storms frequently knock out LAN for hours or days.

Here's how their DPS system works:

• NetGuardian 216 G6 sends SMS alerts over cellular
• Voice dial-out alerts call their on-call technician
• The tech acknowledges the alarm by pressing a button on their flip phone
• If needed, they open the T/Mon web interface on their phone to reboot equipment remotely

This eliminates delays, dead zones, and guessing.
