Reserve Your Seat TodayYour server room equipment doesn't just fail from hardware problems. Temperature spikes, humidity imbalances, water intrusion, and unauthorized access can take down an entire room before anyone realizes something is wrong.
A server room monitoring system gives you continuous visibility into the environmental conditions around your equipment. When something goes out of range, your team gets an alert automatically.
At DPS Telecom, we've deployed monitoring solutions in over 1,500 organizations and manufactured more than 172,800 devices. Our NetGuardian RTUs and D-Wire sensors are purpose-built for exactly this kind of application.

A complete environmental monitoring setup covers the conditions most likely to damage equipment or trigger a failure event.
| Condition | What It Catches |
|---|---|
| Temperature | Overheating from HVAC failure or cooling imbalances |
| Humidity | High moisture that causes condensation damage; low moisture that causes static buildup |
| Water / Flood | Leaking pipes, HVAC condensate, or raised floor flooding |
| Smoke | Early fire detection before suppression systems activate |
| Airflow | Cooling system degradation or blocked venting |
| Door Contacts | Unauthorized access to the room or cabinet |
| Motion | After-hours presence at sensitive equipment |
For a deeper walkthrough of what to track and why, our environmental alarm monitoring guide covers the full picture.
A server room monitoring system has three basic components:
For smaller environments (a single server closet, for example), an RTU with a built-in web interface can serve as your entire monitoring system. You log in at any time to check status, and the unit sends alerts autonomously. For larger deployments across multiple rooms or sites, RTUs report up to a central alarm master like the T/Mon LNX, which aggregates all data in one place. Our guide to planning and buying remote server monitoring tools covers how to scope the right setup for your environment.
The NetGuardian ENV is a dedicated environmental monitoring RTU designed for server rooms, equipment shelters, and IT closets.
It supports D-Wire sensors for temperature, humidity, water detection, and more, and reports via SNMP to any compatible management platform. Every unit is configured to your specific application requirements before it ships.
If you also need to monitor network equipment alarms alongside environmental conditions, other models in the NetGuardian product family add discrete alarm inputs, analog inputs, and control relay outputs in the same unit.

D-Wire is DPS Telecom's sensor line for environmental monitoring. Sensors daisy-chain over a single cable run, which simplifies installation in server rooms where you need readings at multiple points (top of rack, bottom of row, near the CRAC unit, etc.).
Available D-Wire sensors include:
All sensors connect directly to NetGuardian RTUs without additional conversion hardware.
When a monitored value crosses a threshold you define (for example, temperature above 85°F or humidity below 20%), the RTU fires an alarm. Notifications can be sent by:
Thresholds are fully configurable per sensor. You can set warning levels and critical levels separately, so your team knows whether a condition needs attention soon or right now.

NetGuardian RTUs support SNMP V1, V2, and V3 (V3 includes encryption). If you already use an SNMP manager such as SolarWinds, IBM OpenView, or Castle Rock, your server room RTUs can report directly to it without requiring a separate platform.
If you need a multiprotocol management layer that consolidates alarms from both SNMP devices and older equipment using protocols like Modbus, DNP3, or TL1, the T/Mon alarm master handles all of them from a single interface.
At minimum: temperature, humidity, and water detection. These three conditions can affect all equipment in a room simultaneously and are typically not reported by the equipment itself.
The NetGuardian sends email and SMS notifications automatically when a configured threshold is exceeded. It can also send SNMP traps to any compatible network management platform.
Yes. All NetGuardian RTUs support SNMP V1, V2, and V3 and integrate with any standards-compliant SNMP manager.
The NetGuardian ENV is optimized specifically for environmental monitoring. Other NetGuardian models add discrete alarm inputs and control outputs for monitoring and controlling network equipment alongside environmental sensors.
Yes. DPS offers a 30-day loaner program where you test the equipment in your environment and pay only for shipping. Equipment also carries a 2-year hardware warranty and a money-back guarantee.
DPS Telecom application engineers work with you to match the right RTU and sensor configuration to your environment before you commit to anything. There's no obligation.
