Northern Apex Updates Its Personnel Tracking Solution

Northern Apex has announced an update to its Personnel Tracking Solution designed to help companies track employees throughout their facilities as part of security and safety processes. The solution uses a last-time location system (LTLS) architecture—which, according to Northern Apex, requires less infrastructure and is more cost-effective than a real-time location system (RTLS).

The LTLS system uses choke points—sensors on doors in key areas—to track the last time an employee passed through a location. From that, the system uses algorithms to make logical decisions regarding where that individual is located within a building.

The new upgrade features improved software algorithms that have been designed to provide more accurate readings, the company reports. "In some cases," explains Kevin Knuth, Northern Apex's business development manager, "we have adjusted our antenna and tag choices to help as well, but since each installation is custom, this varies by customer." While installations are custom and vary in terms of equipment, Knuth says, the preferred implementation is driven by the company's custom software, in concert with Impinj Speedway Revolution readers and tags made with Monza 5 and 6 RFID chips.

"Our system isn't like what you see in the movies," Knuth says. "In Mission Impossible, they can track someone and watch them walking along a corridor. That's an option we can provide if a customer wanted it, but we've found most companies don't need that level of granularity. The greater the granularity, the more expensive the system. Our system is designed for companies that need to track employees in and out of secure zones, such as a bonded warehouse or a high-value item lock-up area in a department store. It's a cost-effective solution to personnel tracking, and the uses are limited only by your imagination."
