Troubleshooting Power Issues
This page outlines how to diagnose and fix power-related issues for the OV80i system.
note
The camera does not support PoE. Power must be supplied via the dedicated Power & D I/O cable using a 19–24V DC power source.
Common Symptoms
- No LED activity when power is applied
- Camera keeps rebooting unexpectedly
- Excessive heat near connectors or casing
- No response to trigger or web UI access
Step-by-Step Troubleshooting
1. Verify Power Supply
- Use a regulated 19–24V DC adapter (e.g., 65W 19V PSU)
- Confirm voltage with a multimeter before connecting
- Ensure correct wiring using the pinout below
Power Pins to Check (on Power & DIO cable):
| Pin # | Wire Color | Description |
|---|---|---|
| 7 | White/Green | +24V Input (Vin+) |
| 8 | Pink, Yellow | Ground (Vin−) |
2. Check Cable & Connector Fit
- Use only the M12 circular power connector (3m, p/n 1700033944-01)
- Align the notches and securely fasten the threaded collar
- Make sure the connector is fully inserted before powering on
warning
Do not power the camera via USB-C or HDMI or POE. These are not power inputs. HDMI now provides a read-only HMI display, and USB-A/C are reserved for future/support use. Use only the M12 power connector for power.
3. LED Behavior Check
| LED | Color | Meaning |
|---|---|---|
| Power Status | 🟢 Green | Powered on (normal) |
| 🔴 Red | Power Fault | |
| Ethernet Status | 🟠 Orange | Ethernet connected/active |
| User-Defined | 🟡/🟠/🟢 | Application-specific |
4. Try Alternate Hardware
- Swap in a different power adapter (19VDC, 3.42A recommended)
- Try another Power & DIO cable if available
- Disconnect any connected devices (PLC, sensors) and power the camera alone
5. Use the Reset Button
- Short press (Pin 4 to Pin 9): Reboots the camera
note
Only perform a reset with the cable properly seated and power applied.
Still Not Powering?
If the camera still shows no signs of power:
- Double-check cable orientation and seating
- Test with another known-good camera setup
- Contact Overview Support with:
- Power supply details and voltage reading
- A photo of the M12 connector in use
- Any visible LED behavior or overheating notes
