Summary

This article explains the steps to set up loitering to trigger a strobe and send an HTTP request using the XNF-9013RV.

Preparing the Equipment

Gather and set up the following equipment as shown in the picture below.

To power the relay:

Wire the 12V Power Supply to the relay.
Confirm that positive goes to positive and negative goes to negative on the relay.

To connect the XNF to the relay:

Wire the Black wire from the XNF to DC- (Negative) of the relay.

NOTE: Depending on the sensitivity of the Relay – this may require a small resistor 
between the negative from the XNF to the relay.

To connect the strobe to the relay:

Complete the circuit to the strobe to receive power.
Wire the positive wire from the strobe to the positive (DC+) of the relay.
Wire the negative wire from the strobe to the NO (Normally Open) on the relay.
Using a separate wire, wire the DC- to the COM terminal. This is required to compete the circuit when the relay switched after being triggered.

To set up the alarm output and event:

Navigate to the camera GUI.
Verify that the camera is on latest firmware. For this example, the XNF-9013RV is on firmware 2.23.03.
Navigate to Event, and select Alarm I/O.
Select I/O 1 and set it to Output.
Click Apply.
Select NO (Normal Open) for I/O 1 Type.
Navigate to the Analytics, and select IVA.
Select the checkbox by Enable IVA.
Select Virtual Area tab. In this example, we selected Person as the object to detect.
Enable Loitering and set the required minimum Duration. For this example, it is set to 4 seconds. In this example, we created one Area by dragging the mouse.
Navigate to Event, then select Event Rule > Add to add a new rule.
Create a rule to trigger output from IVA.
