Why Use RLC-100?

Create an automatic RFID monitoring point above the operational route

Use RLC-100 where tagged assets pass through a defined entrance, room or checkpoint and the project needs event capture, local processing and alert integration without placing reader equipment in the traffic path.

01

Monitor the route without using floor space

Install the reader above or beside the monitored zone to keep the passage clear while capturing compatible tagged items moving through the intended area.

02

Trigger monitoring around detected movement

Use the confirmed infrared or radar configuration to support event-driven RFID reading and audible or system alerts at controlled entrances and asset zones.

03

Process, cache and route events locally

Use Android-based edge handling, local caching and HTTP, MQTT, TCP or UDP communication to reduce raw-data traffic and maintain event continuity during temporary connection loss.

Before / After

From manual zone checks to automatic overhead RFID event capture

Replace repeated observation and item-by-item confirmation with a configured overhead checkpoint that detects movement, captures compatible tags and forwards a validated event.

Before

Manual asset-zone checking

Five repeated actions at the monitored area

Operator manually checking tagged assets item by item at a storage zone
01Watch the zone
02Stop the movement
03Find the label
04Confirm the asset
05Record the result

The process depends on an operator being present and completing the same confirmation sequence for each movement.

02Reader captures tags
03System receives event
ResultTagged movement can be recorded or escalated without a repeated item-by-item manual check.

RLC-100 supports zone-event monitoring; it does not by itself provide exact real-time item coordinates, guaranteed person-to-item association or room-wide inventory coverage. Final behavior depends on the complete hardware, tag, sensor, mounting and software design.

Overhead RFID Zone Monitoring

Monitor tagged movement without placing equipment in the traffic path

Mount the reader above or beside a defined route and configure the RFID, movement-sensing, alert and event-forwarding behavior around the actual operational checkpoint.

Deployment Guidance

Design the overhead read zone around the route, tag and trigger

The stated read distance is not the design target by itself. Build the monitoring point around the real mounting height, passage geometry, tag orientation, tagged material, sensor behavior and adjacent RFID zones.

Validate the complete event—from movement detection and RFID capture through local processing, alert behavior and system receipt—under the operating conditions expected at the site.

01Select the monitoring point and mounting height

Define the asset route, passage width, installation surface, service access and the area that must remain outside the intended read zone.

02Match the trigger and RFID coverage

Confirm the sensor option, antenna configuration, RF power, tag orientation and timing needed to capture the intended movement without excessive nearby reads.

03Validate data, cache and alert behavior

Test the final protocol payload, duplicate handling, connection-loss behavior, recovery process, buzzer or external alarm and business-system response.

Deployment FAQ

RLC-100 ceiling-reader, sensor and read-zone questions

How is RLC-100 different from a conventional fixed RFID reader?

RLC-100 is designed as an overhead or wall-mounted monitoring terminal that combines UHF RFID reading, Android-based edge processing, local caching, network protocols and a configurable infrared or radar sensing option. A conventional fixed reader may require separately positioned antennas and external event-processing software.

Is the stated read distance of up to 3.5 m guaranteed?

No. The supplied document states up to 3.5 m depending on the tag and antenna configuration. Actual performance depends on mounting height, tag type, tagged material, orientation, RF power, surrounding metal, movement path, interference and the required read-zone boundary.

Can RLC-100 locate the exact position of every tagged item?

The supplied information supports RFID zone monitoring and asset-movement workflows, not precise real-time coordinates. Exact location, person-to-item association or RTLS functions require additional confirmed hardware, algorithms and system design.

Are infrared and radar sensors both included?

The supplied document states infrared or radar sensing. Confirm whether the quoted RLC-100 configuration uses infrared, radar or another sensor option and whether the function is standard or optional.

Can the reader support unauthorized-movement alerts?

It can support an RFID-based alert workflow using movement sensing, tag capture, local logic, audible or buzzer output and a connected application. The final authorization rules, transaction data and alarm escalation remain part of the project software and system design.

Can RFID events be sent to WMS, MES, security or IoT platforms?

The supplied information lists HTTP, MQTT, TCP and UDP. These protocols can be used in a project-specific integration layer, but this page does not claim a native connector for every WMS, MES, security or IoT platform.

What happens if the network connection is interrupted?

The supplied information states that event data can be cached during connection loss and transmitted automatically after connectivity returns. Confirm the exact cache capacity, retention time, retry order and duplicate-control behavior for the selected configuration.

Does RLC-100 support Wi-Fi, Bluetooth, 4G or positioning?

These functions are listed as optional. Confirm the required wireless module, antenna, regional bands, SIM requirements and positioning option before ordering.

How can RLC-100 be installed?

The supplied specifications list ceiling, wall and pole installation. The final bracket, mounting surface, service clearance, cable route, safety retention and structural support should be reviewed for the project.

Can the reader be installed outdoors?

The supplied document provides temperature and humidity values but does not state an IP rating. Do not assume outdoor suitability until the final enclosure rating, sealing, condensation, UV and installation protection are confirmed.

What should be confirmed before ordering?

Confirm the RFID engine, memory, Android version, sensor option, antenna parameters, mounting height, tagged items, read-zone boundary, cache requirement, protocol payload, alarm behavior, I/O, power, wireless options, installation hardware and operating environment.
