Q&A

1 minute.

Each device takes 2-3 minutes to install.

Up to 88,209 units.

It functions well from -30°C to 80°C.

Dust and dirt do not affect the device's performance, as messages can pass through walls.

Each Rack Sentinel device is mounted on the back side of the load beam, which shields it from front-facing forklift contact. Because forklift impacts almost always come from the aisle side, the sensor stays protected while still measuring beam deflection accurately.

Each Rack Sentinel sensor runs for 12 to 18 months on a single battery under normal warehouse conditions. The device monitors its own battery voltage and sends a low-battery alert before it dies, so replacement happens on a planned cadence rather than on failure.

When the battery is low, the device will send an alert to the assigned person requesting a replacement.

The device monitors battery levels and sends alerts when they are low, so there's no need for regular mass replacements. The battery lasts over 18 months under normal conditions.

No maintenance required.

No, it has internal memory that retains the last settings, even after battery replacement.

The device will detect it and instantly send an alert to the assigned person.

The device will continue sending alerts until the overweight issue is resolved.

Yes, it waits 5 seconds to confirm the overweight condition. If the load shifts longer than 5 seconds, it sends an alert, but will notify users when the beam returns to normal.

Rack Sentinel only fires an alert when measured beam deflection exceeds the configured threshold for more than 5 seconds, which filters out transient load shifts during pallet placement. We have not observed false positives in production; if one occurs, the device can be reset from the dashboard or by power-cycling.

Each device sends a message to the gateway, which passes it to the cloud. Modern cloud technology can handle millions of messages.

Yes, users can customize thresholds for various pallets and beam lengths.

Yes, by performing data analysis. We offer this service as part of a premium package.

Each time the device is turned on or off, it sends a message to the assigned person.

Every power-state change is reported to the cloud, so the assigned safety contact receives an alert the moment a device is turned off, removed, or loses power unexpectedly. Tamper attempts are visible in the dashboard audit trail.

Yes. Rack Sentinel supports role-based access so warehouse managers, EHS leads, and frontline operators each see the alerts and configuration scopes appropriate to their role.

No. Each sensor talks to a gateway over encoded radio, and only the gateway needs WiFi or Ethernet to reach the cloud. This keeps deployment cheap in large or RF-noisy warehouses where blanket WiFi is impractical.

Each gateway is designed for a 100-meter radius to surrounding sensors, though steel racking, freezer walls, and pallet density can shrink that in practice. For larger or partitioned facilities you can install multiple gateways, and a handheld signal-verification unit is used at install time to confirm coverage before sensors go live.

The system automatically resumes functionality when Wi-Fi is restored.

The system uses encoded radio communication, so there's no interference with Wi-Fi.

Updates are done over-the-air (OTA) from the cloud, requiring no user intervention.

Yes, generating reports is part of our premium service package.

Sensor-to-gateway traffic uses encoded radio; gateway-to-cloud traffic is TLS-encrypted to AWS IoT Core. Customer data is segregated per account in the cloud backend, and the platform is built by engineers with backgrounds in cloud security and data privacy.

Rack Sentinel is designed to help warehouses meet OSHA general-duty obligations around storage-rack safety (29 CFR 1910.176) by giving teams continuous, documented monitoring of rack condition. We do not currently hold OSHA certification ourselves — OSHA certifies workplaces, not products — and we are actively pursuing the relevant product safety listings.
