Datacenter environment monitoring and access control systems

Comprehensive Monitoring Solution for Modern Data Centers

Comprehensive solution of environment monitoring and access control for data centres. The temperature and humidity monitoring can be extended to number of checkpoints and additional sensors.

In 2025, this solution was updated to demonstrate the advantages of using Perseus platform units for this type of monitoring installation.

Issue description: 

A company operating a network of datacenters and server solutions needs to implement a suitable monitoring system. The company operates large datacenters as well as smaller premises, and also offers server housing services. In this sector, environment monitoring is a must; be it in a room or just in a particular cabinet. 

Datacenters usually represent substantial investments that can reach hundreds of thousands of dollars. Damages in case of adverse events can be even higher due to the stored and managed content. 

​

Potential risks:  
- Overheating of components with subsequent fire
- Water flooding the room including the cabinets
- Unauthorized person entering the premises, or loss of / tampering with data

​

The second requirement was to implement a suitable access control system to keep track of who and when entered the premises, and capable of assigning access rights to particular doors to individual technicians.

Both requirements of course include the option to connect the system to a custom SNMP SW.

Solutions

Requirements:

  • Temperature/humidity sensors with the 1-Wire bus or RS-485

  • Digital inputs, including 3rd party detectors, digital outputs

  • Water sensing cable

  • Communication using SNMP, MQTT

  • Alarms via email, SNMP trap, relay switching (signaling a horn using relay output), additionally SMS/Call alerts

LAN Perseus Monitoring 150 offers perfect top-of-the-line monitoring unit, suitable for datacentre environmental monitoring.

Eight 1-Wire ports, one RS-485 port, and sixteen dry contact digital inputs offer capability that is sufficient for connecting up to 100 meters of any type:

  • Temperature, Humidity or combined Temperature/Humidity sensor

  • Water Leak Detection sensing cable A

  • Power detector/switch

  • Door contact detector

  • Motion detector

  • Smoke detector

  • Airflow detector

  • DO relay

If multiple monitoring zones are needed for water detection with WLD sensing cable, Perseus platform offers capability for adding multiple zones via WLD-Relay.

With the addition of SMS gateway multiple Perseus devices without LTE can all use single gateway for SMS and Call alerts. SensDesk Technology is available for installations and projects wishing to have their data and control over monitored parameters, as well as the device itself (relay outputs switching) in the cloud SaaS solution.

Benefits

  • Ethernet: RJ45 (100BASE-T); WEB: Built-in web server

  • 8xRJ11 port - max. 2 external sensors 1-Wire UNI per port

  • RJ11 sensors: Temperature, Relative Humidity (Indoor / Outdoor), Voltage, Current (0-30A or 4-20mA) and much more

  • RS-485 (Modbus/RTU): 1x terminal block

  • WLD: 1 zone for external Water Leak Detection sensing cable

  • DO (Digital Outputs): 4x DO (relays)

  • DI (Digital Inputs): 16x DI (dry contact)

  • Detectors: Smoke, door contact, fan failure detector, power presence, etc

  • Device Alerts: SNMP trap, email, (SMS / Calls with external SMS GW)

  • Portal Alerts: Email, SMS / Calls, Device Invalid Alert

  • Open API: SNMP, XML, Modbus/TCP, MQTT, BACnet

  • Professional product: IPv6, SNMP Traps, SNMP v3

  • Security: Radius - IEEE 802.1X, Admin and user accounts, HTTPs (customer certificate)

  • Meters API (LAN): HWg devices XML, Modbus/TCP, SNMP, MQTT

  • Data processing: Condition & Actions, Virtual sensors, Scheduler

  • Remote Configuration with SensDesk Technology
