Beacon: Wireless Passive Monitoring Device
for warehouses, transportation & pharma cold chain
Enabling seamless, near real-time monitoring across warehouses, transportation, and the pharmaceutical cold chain. Continuously capturing temperature data, ensuring full visibility, compliance, and product safety throughout storage and distribution. Send us a message
Scalable Wireless Monitoring for
500+ Partners
Challenges you can overcome with Beacon passive monitoring
Wired complexity vs. True Wireless Deployment
Traditional passive monitoring systems often require cables or fixed installations, limiting flexibility and increasing setup effort.
Fully wireless device design enables fast deployment anywhere without cabling or infrastructure changes
Hidden environmental risks vs. Continuous Passive Tracking
Critical changes in temperature or conditions can go unnoticed between manual checks or active polling intervals.
Always-on passive sensing captures every measurement point for complete environmental visibility
Fragmented monitoring vs. seamless data capture
Some systems rely on multiple components or manual logging, creating gaps in recorded data.
Integrated passive logging ensures continuous, uninterrupted data collection in a single device
Limited placement options vs. Total Installation Freedom
Fixed or wired sensors restrict where monitoring can take place, especially in temporary or hard-to-reach environments.
Wireless design allows flexible placement across warehouses, transport boxes, or remote environments
Data Logger for Cold Chain
Tec4med’s wireless temperature monitoring devices are called “Beacons” and continuously store data on their internal memory. The data can be collected using our SmartHub gateway or Tec4App for smartphones. The recorded data is then uploaded to Tec4Cloud for convenient access and analysis.
Our passive monitoring solution ensures compliant temperature reporting of your refrigerator, freezer, warehouse, storage, etc. In case of temperature deviations, alerts are sent immediately via email and browser.
We offer two versions of our Beacons: TempBeacon and CryoBeacon, which is equipped with a digital/analogue interface that facilitates the connection of external probes.
Your Benefits
Efficient, targeted monitoring
Focus resources on critical shipments and high-risk scenarios instead of over-monitoring every asset, improving operational efficiency.
Scalable compliance management
Easily expand monitoring across higher volumes and multiple locations without increasing system complexity or compliance workload.
Simplified operational workflows
Reduce manual checks and administrative effort through automated data capture and centralized monitoring.
Stronger audit readiness
Generate reliable, continuous records that support regulatory requirements and simplify inspection processes.
Reduced risk of product loss
Act faster on deviations and trends to prevent spoilage, ensuring higher product integrity and reduced financial loss.

Tec4App for Near Real-Time Monitoring
Tec4App for Near Real-Time Monitoring
The Beacon Wireless Passive Monitoring Device streamlines temperature monitoring by enabling bulk readout of multiple devices through the Tec4App, eliminating the need to scan each logger individually. Collected data can be uploaded to Tec4Cloud in a single step, providing a centralized view of all monitoring records across shipments and storage locations.
This unified workflow reduces manual effort, accelerates data collection, and ensures complete, audit-ready documentation. Whether monitoring warehouses, distribution hubs, or pharmaceutical shipments, Beacon delivers efficient wireless data capture, simplified compliance, and seamless integration into your existing cold chain monitoring process.
Frequently asked question about Tec4med’s wireless passive monitoring
The Beacon continuously records temperature and environmental data throughout storage or transport. Data is stored on the device and can be wirelessly collected using the Tec4App whenever required.
Yes. After readout, measurement data can be uploaded directly from the Tec4App to Tec4Cloud, where it is securely stored, visualized, and available for reporting and compliance documentation.
No. The Beacon operates independently and stores measurements locally. An internet connection is only required when uploading collected data from the Tec4App to Tec4Cloud.
Yes. The wireless design makes the Beacon ideal for warehouses, cold rooms, transport containers, insulated packaging, and pharmaceutical shipments.
Absolutely. The combination of wireless operation, bulk readout through the Tec4App, and centralized cloud management makes it easy to monitor hundreds or even thousands of devices across multiple locations.
