Each Verkada Air Quality Sensor is equipped with an outside LED light. This light indicates its operating status. Verkada offers the SV11 series and SV20 series (including SV21, SV23, SV25).
A flashing white (SV20 series) or flashing blue (SV11) status LED on the front of the sensor indicates the sensor is not communicating with Verkada Command. If you see this behavior:
Check that the network is set up correctly for the sensor’s requirements.
If the problem persists, contact Verkada Support.
When sensors are offline, alerts/events do not trigger. They continue to record measurements and sync with Command once they reconnect.
SV20 series
The SV20 series may reboot where the device recovers with an internet connection or without one. A reboot technically still results in some data loss (no more than 5 minutes of the latest data).
If the SV20 series sensors lose an internet connection, these scenarios can occur:
Scenario Status | Sensor Result |
Sensor still has power and has not rebooted after internet loss. | Sensor should record data as usual, as long as the sensor gets uninterrupted power. |
Sensor power cycles after loss of internet within 24 hours. | Command still records data as usual. |
Sensor powers off for more than 24 hours. | Command does not record data, because the RTC on the device is no longer reliable. |
SV11
As of December 13, 2021, the SV11 supports offline storage.
If the SV11 sensor loses an internet connection, these scenarios can occur:
Scenario Status | Sensor Result |
Device loses internet connectivity. | Device continues recording data indefinitely |
Device reboots at any point while offline. | Device does not record data when rebooted. An internet connection must be resumed for data recording to resume, because of the lack of an RTC. When the device reboots, the timestamp is unknown until an internet connection resumes. |
For all sensors
If any Verkada sensor loses an internet connection, these scenarios can occur:
Scenario Status | Sensor Result |
Device goes from online to offline. | Device records data. |
Device is offline (not connected to internet, but still powered on, then reboots with no internet. | Device does not record data from that point. |
Device reboots with no internet, then internet resumes. | Device recording resumes. |
Required. The device must be online for (Command) to retrieve data from it. If the device is offline, you cannot view sensor data. You should receive an alert (if you previously set up sensor events and alerts) when their device goes offline.
