The Darca Solutions Suite
One connected monitoring platform: Collect. Connect. Command
Whether you deploy wired or wireless monitoring, Darca connects sensors, connectivity, and cloud software into one intelligent platform delivering complete visibility, real-time alerts, and actionable insight.
The architecture
From measurement to meaningful insight
Whether you're monitoring with wired or wireless devices, Darca brings everything together in one connected platform. Collect measures environmental conditions, Connect transfers data securely, and Command provides the visibility, alerts, and reporting you need to make confident decisions.
Trusted by leading organisations including the Natural History Museum, Westminster Abbey and the University of Edinburgh.
Collect
Wired PT probes and wireless transmitters and repeaters, the sensing layer that scales across large, complex sites.
Connect
SRV450 hubs and SMS450 alarms, the connectivity layer that relays wired or wireless data and keeps people notified.
Command
Darca Command cloud, live dashboards, alarms and compliance-ready reporting, on any device, wired or wireless.
Darca Collect · The sensing layer
Measure. Extend. Monitor.
Accurate environmental data from every location that matters.
Darca Collect is the sensing layer. Wired PT resistance probes and wireless GenII transmitters capture accurate temperature, humidity and environmental readings across large, complex sites, and reach the places that are hardest to monitor, without invasive cabling through sensitive or listed fabric.
- Wireless GenII transmitters for temperature, humidity, CO₂, differential pressure and more
- Wired 3-wire and 4-wire PT resistance probes for high-accuracy fixed points
- Probes and sensors matched to harsh, regulated and hard-to-reach environments
- Repeaters that extend range across large, multi-zone and multi-building sites
Darca Connect · The connectivity layer
Connect. Collect. Protect.
Darca Connect is the connectivity layer, the secure link between your sensors and the cloud. Whether readings come from wired loggers or wireless transmitters, Connect keeps data flowing and people notified, so a problem becomes an action, not a missed reading.
SRV450 hub
Gathers data from your wireless network and relays it securely to the Darca Command cloud, a single-box link from site to software.
SMS450 alarms
Turns a threshold breach into an instant SMS alert, so a problem is escalated to the right person the moment it happens.
Darca Command · Cloud monitoring platform
Monitor. Alert. Assure.
Darca Command is the cloud layer of the suite, the single place your team monitors conditions, investigates trends and proves compliance. Data from every wired and wireless device flows into one secure platform, so whether you run one site or a national estate, the whole picture is one login away.
Any device. Any location. Darca Command runs in the browser, so you can check live conditions and respond to alarms from the lab, the plant floor or your phone on the move.
Live dashboards, every site and zone
See current temperature, humidity and conditions across the whole estate at a glance, then drill into any single sensor.
Real-time alarms
Breaches raise instant alerts by SMS, email and on-screen, so the right person responds before conditions cause damage.
Compliance-ready reporting
Scheduled and on-demand reports with full audit trails, suited to regulated environments including GxP, GMP, HTA and 21 CFR Part 11 workflows.
Documentation & records
Keep calibration certificates, procedures and evidence attached to the sites and sensors they belong to.
User management & permissions
Role-based access keeps the right people in control across teams and sites.
Per-site configuration
Tune sites, zones, thresholds and schedules to match exactly what each environment needs.
Eltek Bridge · BRI-250
Bring your legacy system into Darca
Wirelessly receive data from legacy transmitters into your Eltek monitoring system.
For sites already running a legacy Eltek system, the Eltek Bridge (BRI-250) links those existing transmitters into your current monitoring setup, and lets you add new transmitters to the same network. You keep the equipment you have already invested in, and extend it, rather than starting over.
From there, the Darca Solutions Suite layers live dashboards, alarms and compliance-ready reporting on top, bringing your installed base into one connected, cloud-monitored system.
- Twin-antenna wireless receiver for reliable reception from existing transmitters
- Extends, rather than replaces, your current Eltek installation
- Add more transmitters to the system you already run
From the field
We have found the Eltek Bridge and Darca Command software to be very user-friendly. The modern interface makes it easy for us to view data and create charts and reports. Eltek has listened carefully to our feedback in developing and improving the system and has been extremely helpful and responsive throughout the process.
