Remote Site Monitor

The Remote Site Monitor software from Comet Electronics allows users in the Rail community to view with a quick glance the health of their wayside assets.  This software also facilitates highly configurable settings to allow site maintainers to get notifications via email or text when issues are flagged by the reporting equipment.  The issue tracking, issue assignment and issue resolution features provide a proactive approach to visibility of any issues that may arise from your wayside equipment.  View the demo video linked below and call Comet today to begin the process of getting your sites monitored tomorrow.


DynaCam Field


Expand the capabilities of existing Comet AEI systems with car asset health monitoring. Thermal wheel anomalies can be identified down to the car ID and wheel position as a railcar passes the scanning area. Users receive automated notifications allowing for a real-time response to sliding wheels, over/under applied braking, thermal bearing/wheel analysis and more to protect from potential derailments.

Railert ATR

The Railert Automatic Tag Reader(ATR) System bridges the gap between a hand-held data recorder and the traditional full featured AEI system.

Some of the difficulties normally faced with a AEI systems are:

  • Collecting tag data with a hand-held reader is overhead intensive.
  • Purchasing a traditional AEI system can be expensive
  • Traditional AEI systems can provide more functionality than needed

Until now! The Railert ATR is designed to offer a simplified, lower cost option over previous offerings.

Railert ATR is a single-antenna unit with modular components mounted inside a NEMA 4 box. The modular design makes installation and repairs fast and easy. The NEMA 4 box also eliminates the need for expensive shelters. Each unit is fully assembled and tested directly in  house prior to shipment. As an additional cost savings benefit, the Railert ATR is now configured to be installed by you! Contact us for details and pricing.

The system accurately captures data at infrequent intervals regardless of weather, from radio frequency (RF) tags mounted on locomotives traveling up to 30mph.  Reports are generated instantly and delivery via email.

Easy to buy, simple to operate with minimal maintenance are just a few of the benefits of purchasing the system.  The system is provided to you from one of the most trusted names in rail communication; Comet Electronics.

Note: The Railert ATR does not report the presence of non-tagged cars and therefore it is not meant for use where an AAR S-918 compliant AEI system is required.
