If you're evaluating proximity detection for your facility, the hardest part usually isn't finding vendors. It's knowing what to actually ask them.
Every system on the market claims to protect workers. The real differentiators exist in how each technology performs under the specific conditions of your facility, not in a controlled demo.
Before you make a decision, get clear answers to these questions:
How does the system detect?
Does it use cameras, RF, UWB, magnetic pulse, radar, or something else? Each technology has different performance characteristics in obstructed or challenging environments. Understanding the method tells you where the system will perform well and where it may have limitations.
What happens when the path between the equipment and the pedestrian is obstructed?
Racks, loads, walls, and blind corners are everyday realities in most facilities. Ask specifically how the system behaves when there's something in the way, not just in open-floor conditions.
Who gets alerted, and how?
Does the alert reach the operator, the pedestrian, or both? What form does that alert take — visual, audible, haptic? How much reaction time does it realistically provide at typical operating speeds?
What are the environmental limitations?
Ask about performance in the specific conditions of your facility: metal infrastructure, dust, variable lighting, temperature swings, or high-noise environments. Every technology has a profile of where it works best.
What does the wearable or tag dependency look like?
If the system requires pedestrians to carry or wear a device, what happens if a device isn't charged, isn't worn, or fails? Is there any indication that protection is compromised?
What does implementation actually look like?
How long does installation take? What disruption should you expect? What training is required for operators and pedestrians?
What does support look like after installation?
Who do you contact when something needs attention? What are typical response times? Are replacement parts and technical support readily available?
Honest answers to these questions will tell you more about a system than any demo will.
