RSA IVR Unexpectedly Offline
An RSA IVR may successfully install, onboard, and connect to the Spot dashboard, but later drop offline and fail to reconnect.
Network Verification — SIM Card / Cellular Connectivity
Verify there are no network issues in the area
If the unit is using a SIM card, ensure the cellular network service is stable in that location
If you have multiple units in the same area experiencing the same issue, this is a strong indicator of weak or unstable network service in that zone
Contact your cellular provider to verify signal strength and network availability in that specific area
Check if the issue is isolated to one unit or affecting all nearby units — this helps determine if it's a device issue vs. a network coverage issue
If Using a Modem:
Make sure the modem is physically connected to the network
Verify the modem has not been accidentally disconnected
Confirm the modem is powered on and all indicator lights are normal
Check all cable connections are secure (power and Ethernet)
Try rebooting the modem if connectivity is still not restored
Battery issue
Installation Issues
Check for loose connections around the power circuitry that may be causing unexpected power loss to the IVR
Faulty Components
Components such as the DC-DC regulator can fail after prolonged use — inspect and replace if needed
Victron MPPT Users
Verify battery status and charge levels through the Victron app
Install battery over-discharge protection so the IVR can reboot once a drained battery begins charging.
Solar-Powered RSA Units
If not enough solar power is generated, batteries can fully discharge and cause the IVR to shut down
The unit may fail to boot on the next charging cycle and require manual recovery
Make sure solar panels are clean and receiving adequate sunlight
Tech on-site Checklist
Each pole mount unit uses two DC-to-DC converters. If you are using your own trailer unit, also verify the following:
DC-to-DC #1 — Powers the IVR
DC-to-DC #2 — Powers the cameras, speaker, and IVR
There is an LED indicator on all AC and DC batteries
If it is working — LED light should be ON (color may vary, currently blue)
If it is shorted or fails, the LED light will be OFF
Input/Output Testing with Multimeter
Use a multimeter to test input and output voltage, Test positive (+) and negative (−) terminals (it's marked on the battery)
Verify correct voltage is reaching each component
Verify correct wiring for the battery
Make sure there is no loose connector
Make sure wirings are not cross-connected
DC-to-DC Wiring (2 cables)
Connector goes into two DC-to-DC converters
Black = Negative (−)
Yellow or Red = Positive (+)
AC-to-DC Wiring (3 cables)
White = Neutral
Black = Live / Line
Green = Ground
Conduit runs to the panel
IVR online and cameras are offline
Make sure DC-to-DC #2 — Powers the cameras, speaker, and is working test above, verify there is no issue with the battery
If there issue issue bringing 1-2 cameras offline or the speaker is offline, make sure each camera and speaker are connected to the power and network ( ethernet cable)
Water Issue
Check for water ingress around the unit enclosure
Ensure the bullhorn is placed flat-side down ( not up ) so that it will not gather water
Make sure the bullhorn black gasket is properly secured to maintain a watertight seal. The cable should not move around when the gasket is properly secured.
