DVR Add-On Camera Spotlight Keeps Flashing
Last updated:
If the spotlight on your Swann DVR add-on camera keeps flashing, the issue may be caused by insufficient power or a damaged cable. This can happen when a camera that was working normally suddenly starts flashing or when the issue occurs during the initial setup.
DVR add-on cameras connect to the DVR using a video cable with a BNC connector and a separate power connection. Unlike a feature that can be enabled or disabled through settings, the spotlight should not flash as a normal camera feature. Troubleshooting should focus on the camera's power supply and cable connections.
Before You Start
Before troubleshooting, make sure you have the following:
- Access to the DVR and its connected add-on cameras.
- Access to the camera's power adapter, power splitter, and cables.
- A safe way to disconnect and reconnect the camera's power connections.
Safety note: Disconnect power before inspecting or reconnecting cables. Do not use damaged cables or power adapters.
Common Causes
A flashing spotlight on a DVR add-on camera may be caused by:
- Insufficient power: The 12V power adapter or wall outlet may not be supplying enough power.
- Damaged power adapter: The adapter may be faulty, especially if the spotlight started flashing after working normally.
- Damaged camera cable: The camera's video cable or power connection may be damaged.
- Damaged power splitter: The splitter distributing power to multiple cameras may be faulty.
- Cable length: During a first-time setup, a cable that is longer than expected may require more voltage to deliver sufficient power to the camera.
- Incorrect power distribution: Cameras using longer cables may need a separate power arrangement from cameras using shorter cables to avoid overvoltage damage.

Step-by-Step Fixes
Check the 12V Power Adapter and Wall Outlet
If the spotlight started flashing after the camera had been working normally, check whether the power adapter or wall outlet is supplying sufficient power.
- Disconnect the power adapter from the wall outlet.
- Inspect the adapter and its connections for visible damage.
- Make sure the adapter is securely connected to the power splitter.
- Plug the adapter into a different, known-working wall outlet.
- Restore power and check whether the spotlight still flashes.
If the spotlight continues flashing, the power adapter may be faulty or unable to supply sufficient power.
You can also test the camera using the DVR's power adapter, provided it is a compatible 12V adapter and the connections are suitable.
When swapping adapters, check their output ratings:
- Matching output ratings: If both adapters are rated at 12V 2A, for example, swapping them can help determine whether the original camera power adapter is faulty.
- Different output ratings: Do not assume the adapters can be swapped just because both provide 12V. Check the required output current for each device.
- 16-channel DVRs: These commonly use a higher-rated power adapter, typically 3A to 5A. The camera's lower-rated adapter may not provide enough power to operate the DVR, so swapping the adapters may not be practical.
Expected result: If the camera works normally with a known-working, compatible adapter, the original adapter may be faulty. If the spotlight continues flashing, inspect the power splitter, camera cables, and cable length.
Important: Always use a compatible 12V power adapter with the appropriate output rating. Do not use an adapter with an unsuitable voltage or insufficient current capacity.
Inspect the Camera Cables and Power Splitter
A damaged cable or power splitter can prevent the camera from receiving sufficient power, causing the spotlight to flash.
Check all three components:
- Camera cable: The cable connecting the camera's power and video connections to the system.
- Power splitter: The component that distributes power from one adapter to multiple cameras.
- Camera's built-in cable: The cable attached directly to the camera.
Follow these steps:
- Disconnect the camera's power supply before inspecting the cables.
- Check the camera cable for cuts, exposed wires, bent connectors, or other visible damage.
- Inspect the power splitter and its connectors for damage or loose connections.
- Check the cable attached directly to the camera for visible damage.
- Reconnect the components securely.
- Restore power and check whether the spotlight still flashes.
If the issue persists, test the camera using a known-working, compatible cable and power connection, where possible.
Expected result: If a damaged cable or splitter is causing the problem, replacing the faulty component with a compatible one should resolve it.
Check the Cable Length (First-Time Setup)
If the spotlight has been flashing since the camera was first installed, check whether the camera cable is longer than expected.
Longer cables can cause greater voltage drop, meaning less voltage reaches the camera. The longer the cable, the more important it is to ensure the power supply can deliver sufficient voltage to the camera.
Follow these steps:
- Check the length of the cable connecting the camera to the system.
- Confirm that the camera is using a compatible cable and power arrangement.
- If the cable is longer than expected, have the power requirements checked to ensure the camera receives sufficient voltage.
- Check how the camera's power connection is arranged relative to other cameras using the same splitter.
- If the issue continues, test the camera using a shorter, compatible cable to determine whether cable length is contributing to the problem.
Expected result: If cable length or the power arrangement is responsible, correcting the setup should allow the camera to receive sufficient power without exposing other cameras to excessive voltage.
Important:
Keep cameras with longer cables on a separate, appropriately rated power arrangement when required.
Do not simply increase the voltage supplied to all cameras on the same splitter. Cameras using shorter cables may receive excessive voltage, which can damage them over time.
Check the Camera's Power Connection
If the spotlight continues flashing, isolate the affected camera from the other cameras to help identify the source of the problem.
- Turn off or disconnect the camera's power supply.
- Identify the affected camera's power connection on the splitter.
- Check that the connection is secure and that the correct power adapter and splitter are being used.
- If possible, test the affected camera using a known-working, compatible power connection.
- Restore power and observe the spotlight.
If the spotlight stops flashing with a different, compatible power connection, the original adapter, splitter, or associated cable may be faulty.
If the spotlight continues flashing, the camera's built-in cable or the camera itself may be damaged.
Note: Do not connect multiple cameras to an undersized power adapter or use an unverified power supply to perform this test.
Do not factory reset the DVR or change camera settings to resolve this issue. The flashing spotlight is not a camera feature that can be enabled or disabled through settings.
Why Does My DVR Add-On Camera Spotlight Keep Flashing?
A flashing spotlight on a DVR add-on camera may indicate that the camera is not receiving sufficient power or that a cable or power connection is faulty.
This can happen when a power adapter or wall outlet stops supplying adequate power, a cable becomes damaged, or a first-time installation uses a cable length that causes excessive voltage drop. Incorrectly distributing power between cameras can also cause problems, particularly when cameras use cables of different lengths.
To help prevent this issue, use compatible power adapters and splitters, inspect cables periodically, and ensure that cameras receive the correct voltage for their cable lengths.
