Instructions SNMP-capable PIR Motion Detector

This SNMP-compatible Motion Detector Sensor from Didactum is equipped with passive infrared technology and serves the detection of presence and movement in critical infrastructure. Protect important rooms and systems such as computer and server rooms, research and development, production, warehouse logistics or archives with this PIR motion detector. As soon as this sensor detects presence or movement, you and your colleagues are immediately informed by the networked monitoring and control system via SNMP trap, email or SMS.

If you are using a computer or network monitoring tool (e.g. Nagios, Check_MK, OpenNMS, PRTG, Zabbix, etc.), the remote monitoring and control unit also sends messages in the form of SNMP traps. The current state of the sensor (motion detected / no motion detected) can also be queried remotely using the SNMP command. At the same time, the remote monitoring and control unit can issue a visual or audio-visual alarm if desired. To do this, simply connect the flashing light or siren to one of the two 12VDC outputs of the main sensor unit.

Compatibility of the SNMP enabled Motion Detector

The PIR motion detector is compatible with all current measuring and monitoring devices:

Didactum Monitoring System 50/100 (48VDC) / 200 /300 (PoE) / 400/500 (48VDC) / 600 (48VDC) / 700 (48VDC) and Didactum PDU 700

Installation

The PIR Motion Detector from Didactum can be mounted on the wall as well as on the ceiling. Fastening material is included in the scope of delivery. With the support of the ball joint, you can fine-tune this SNMP capable motion detector sensor.

Here is an example of how to connect the SNMP-capable analog sensors from Didactum.

Connection of the PIR Motion Detector to the remote monitoring unit

The PIR motion detector is connected to a free, analog sensor port of the web enabled Didactum remote monitoring unit via plug and play. The expansion unit for analog sensors is also supported by this sensor. An additional power supply is not necessary as this sensor is powered by the main monitor.

On request, you can extend the cable of the motion detector up to 50 meters (approx. 164 ft). Manufacturer Didactum offers suitable sensor cables.

Configuration in the web interface of the monitoring & control system

The connected sensor is immediately displayed in the system tree of the remote control system.
With the support of the autodetect function, this SNMP capable motion detector sensor is automatically detected by the main sensor unit and listed in the responsive webGUI.

Configure this PIR motion detector in the web interface
The configuration menu of the motion detector opens with a mouse click of the mouse. See the name of the sensor, the SNNP OID, the sensor class (discrete), the analog sensor port used (hardware port) and the status monitored in real time. Please leave the sensor in "Normally open" mode. In our example we rename the sensor to " Didactum PIR Motion Detector" and click "OK" or "Apply".
Selection of the timer function with time planning in telecontrol unit.
Definition of the week days and the time
Use a mouse click to select the days and the time when an alarm should be triggered when access, presence or movement is detected. To do this, simply click on the boxes. In our example, no motion alarm is issued from Monday to Friday from 6 a.m. to 6 p.m., since no alarm must be issued during normal working hours. Then we name the timer as " Timer Function Motion Detector" and click "Apply". This rule appears after saving in the "system tree" of the SNMP-based remote monitoring & control system.

Timer function of the PIR Motion Detector

In addition to full SNMP support, e-mail and SMS * notification and alarm features, each Didactum Monitoring System offers other useful additional functions, such as trigger, weekday or timer functions.

In our example we do not want to be notified by the Didactum motion detector on weekdays from Monday to Friday from 6 a.m. to 6 p.m. In the remaining time, an alarm must be triggered when access, presence and movement is detected in our critical infrastructure. We set up a schedule for this in the web interface of the monitoring system. To do this, we go to the "System tree" menu and then click on the "+" sign in the top right. A new menu "Add a new element" appears. We select "Timer" and the corresponding menu is opened automatically:

Setting up notifications, alarms and automatic actions in the remote monitoring & control device.

Alerting when presence and movement are detected

In the web interface under "Logic Scheme" we now set up the desired messages and alarms when the PIR motion detector is triggered. Every SNMP enabled remote monitoring & control device from manufacturer Didactum can send notifications and alarms in the form of SNMP traps, e-mail and / or SMS text messages (* via GSM or LTE modem).
How to set up and configure an e-mail account or the built-in LTE modem in the measurement and monitoring system is shown here in this technology portal. In our example, you and your colleagues receive an alarm when the infrared sensor is triggered by e-mail and SMS *. By clicking on the diskette icon (top right), the rule is then permanently saved in this smart monitoring & control system.
