Most critical infrastructure runs at sites with no full-time staff. Cell towers, equipment shelters, substations, pump houses, and remote communication huts may go days or weeks between visits. Without active monitoring, security threats can go undetected until damage is already done.
Unauthorized Entry Personnel or intruders accessing sites without clearance, whether by forced entry or using outdated access credentials that were never revoked.
Equipment Theft and Vandalism Copper wiring, battery strings, and communications gear are common targets at sites where nobody is watching, especially in rural areas.
Delayed Incident Response Without real-time alerts, security events may not be noticed until the next scheduled maintenance visit, compounding repair costs and downtime.
Incomplete Access Records Paper logs and standalone keypad systems can lack the audit detail compliance teams need to answer questions about who was on-site and when.
At DPS Telecom, we treat security monitoring as one layer of a unified alarm management framework, so entry events arrive in the same system as your environmental and power alarms. A NetGuardian RTU at each site monitors door contacts, motion sensors, and access control inputs alongside those other alarms. Everything reports over your existing transport (Ethernet, cellular, fiber, T1, or serial) to a central T/Mon LNX alarm master, where your operators can see security status across every site on a single map view.

Each component in the DPS security monitoring architecture handles a specific layer of site protection, from physical entry detection through operator notification.
| Capability | Description |
|---|---|
| Door Contact Monitoring | Magnetic contacts on site doors report open/close status in real time. The RTU can distinguish between authorized and unexpected entry events when paired with access control. |
| Motion Detection | Sensors placed inside equipment shelters or around perimeters trigger discrete alarms on the RTU when movement is detected during off-hours or unauthorized windows. |
| Access Control Integration | Our Building Access 32 supports proximity cards, key fobs, PIN keypads, and multi-factor authentication, with a complete access log for every entry event. |
| IP Camera Integration | NetGuardian RTUs can interface with on-site IP cameras, giving operators visual verification of who triggered a security alarm without dispatching a technician. |
| Automatic Alert Escalation | T/Mon LNX sends email, SMS, or pager notifications the moment a security alarm fires. Configurable escalation rules route the alert to the right person based on severity and time of day. |
| Theft Detection | Our Theft Detector monitors copper wiring and battery connections with a sensor loop. If the loop is cut, the RTU reports an immediate alarm. |
The products below address the most common requirements for securing unmanned sites, from field-level intrusion detection through centralized alarm management. Each links to its dedicated product page with full specifications.
NetGuardian G6 832A
The primary RTU for this use case. The NetGuardian G6 832A monitors discrete alarms from door contacts and motion sensors, accepts analog inputs for environmental conditions, and provides control relay outputs for activating locks or sirens remotely.
Building Access 32
A dedicated access control unit that integrates directly with the NetGuardian and T/Mon ecosystem. Manages authorized entry at up to 32 doors with full logging.
T/Mon LNX
The central alarm master station for networks of any size. T/Mon LNX collects security and environmental alarms from every RTU and presents them on a single geographic map view with configurable notification rules.
DPS monitoring equipment is designed to integrate with the gear you already have deployed, regardless of manufacturer or protocol. If you have an existing SNMP manager (such as a third-party Network Operations Center (NOC) platform), our RTUs can report directly to it. If you run older field devices that use proprietary protocols, the T/Mon LNX platform can mediate them into a standard format alongside your security alarms, and its full protocol and transport list covers the formats most commonly found at unmanned sites.

| Industry | How Unmanned Security Monitoring Applies |
|---|---|
| Telecommunications | Cell towers, fiber huts, and remote switching stations run unattended. RTUs monitor door contacts, motion, and temperature to protect equipment and detect intrusion. |
| Electric Utilities | Substations, relay houses, and distribution automation cabinets contain high-value equipment in isolated locations that benefit from integrated access control and alarm monitoring. |
| Government and Public Safety | Emergency communications towers and 911 infrastructure require documented access logs and immediate intrusion alerts to meet compliance standards. |
| Transportation | Railway communication shelters, transit signal houses, and highway ITS cabinets are spread across wide service areas with infrequent staff visits. |
| Oil and Gas | Pipeline communication sites, pumping stations, and remote well-monitoring shelters face both theft risk and regulatory requirements for access documentation. |
| Differentiator | What It Means for You |
|---|---|
| Custom Engineering at No Extra Cost | About 80% of monitoring requirements fit our standard modules. The remaining 20% gets custom-engineered to your specs. We do not charge Non-Recurring Engineering (NRE) fees when minimum order quantities are met. |
| Free Lifetime Tech Support | Our tech support team includes the engineers who designed the equipment. You get direct access to people who understand the hardware, for the life of the product, at no additional cost. |
| 30-Day Loaner and Money-Back Guarantee | Try the equipment in your environment before committing. Our 30-day loaner program lets you test with your own infrastructure. If the solution does not fit, we offer a money-back guarantee and a 2-year hardware warranty. |

Dickey Rural Networks (Telecommunications)
Centralized Access Control Across Unmanned Telecom Sites
Dickey Rural Networks (DRN) needed tighter control and visibility across unmanned remote sites, including both network alarms and physical access events. Using T/Mon with NetGuardian RTUs and the DPS Building Access System (BAS), DRN built over 1,000 user profiles to manage access for internal staff, contractors, and vendors with location-specific and time-based restrictions.
Wheatland Electric Cooperative (Electric Utility)
NetGuardian RTUs for Door Control at Co-Location Sites
Wheatland Electric Cooperative, serving over 33,000 meters across 19 counties in Kansas, deployed NetGuardian RTUs to manage door access at their tower and co-location sites. The RTU-based approach replaced multiple physical gate locks with a centralized electronic system managed through T/Mon.
Midvale Telephone Exchange (Rural Telecom)
Multi-Camera IP Security Monitoring for Remote Sites
Midvale Telephone Exchange implemented IP camera-based security monitoring integrated with their DPS remote site management system for visual verification across their service area.
DPS RTUs accept standard door contacts (magnetic reed switches), passive infrared (PIR) motion sensors, glass-break detectors, and vibration sensors through discrete alarm inputs. Analog inputs support 0-5VDC and 4-20mA sensors for environmental monitoring at the same site.
Yes. NetGuardian RTUs report via SNMP v1, v2c, and v3, so they can feed security alarms directly into any third-party SNMP management platform you already run. You can also use T/Mon LNX as a dedicated alarm master alongside your existing manager.
T/Mon LNX supports automatic notifications via email, SMS text, and pager. Notification rules are configurable by alarm severity, time of day, and assigned escalation groups, so alerts can route to the right person based on the type and urgency of the event.
The Building Access 32 provides a complete log of every entry event, including card/fob ID, timestamp, and door location. These records support compliance requirements for industries that mandate documented access histories at critical infrastructure sites.
Yes. NetGuardian RTUs support multiple transport options including cellular (GSM/CDMA via external gateway), satellite (via external gateway), fiber, T1, serial, and dialup, so you can monitor security at sites that lack a wired network connection.
If you are managing unmanned facilities and need visibility into who is accessing your sites and when, we can help you design the right monitoring solution. Try our equipment risk-free with a 30-day loaner, backed by a 2-year hardware warranty, money-back guarantee, and free lifetime tech support.
