Why is Your Security Camera Power Light Blinking (But Not Working)?

It’s a common and frustrating scenario: You look at your security camera, and while the power indicator light is blinking, there is no video feed on your monitor or app. This "Morse code" of blinking lights is your camera’s way of saying it’s alive, but it isn't healthy enough to function.
In this guide, we’ll break down exactly what those blinking lights mean and how to get your surveillance system back online.
1. Insufficient Power Supply (The #1 Culprit)
By far the most common reason for a blinking power light is inadequate voltage or amperage. Your camera might have enough power to light up a small LED, but not enough to "boot up" the processor or power the infrared (IR) night vision sensors.
Voltage Drop: If you’ve run a long cable to an outdoor camera, the power can "leak" along the way. By the time it reaches the camera, a 12V supply might only be delivering 9V.
Amperage Mismatch: If your camera requires 1.0A (Amp) but your power adapter only provides 0.5A, the camera will likely enter a "reboot loop," causing the light to flash as it tries and fails to start.
Failed Adapters: Over time, power blocks can weaken. A blinking light often indicates the adapter is struggling to maintain a steady current.
2. Network and Connectivity Issues
For IP and Wi-Fi cameras (like Nest, Ring, or Blink), a blinking light often signifies a loss of communication with the router or Sync Module rather than a hardware failure.
Wi-Fi Dropout: Many cameras flash red or blue when they lose their internet connection.
IP Conflicts: If two devices on your network are trying to use the same IP address, the camera may "knock" itself offline, resulting in a status light error.
Router Distance: If you’ve recently moved your router or added a new wall, the signal might be too weak for the camera to stream video, even if it stays powered on.
3. Firmware Corruption or Failed Updates
Modern security cameras are essentially small computers. If the power was interrupted during an automatic firmware update, the camera’s internal software can become "bricked" or corrupted. In this state, the power light will often blink rapidly to signal a system error that prevents it from loading the operating system.
4. Hardware and Storage Failures
If you are using a DVR or NVR system, a blinking light on the recorder (rather than the camera) often points to a Hard Drive (HDD) failure. Because the system cannot find a place to record the data, it may stop displaying the feed entirely to prevent "headless" operation.
Decoding the Blinks: What is Your Brand Telling You?
Brand | Blinking Pattern | Likely Meaning |
Blink | 3-Second Intervals | Wi-Fi Connection Dropout |
Lorex | Rapid Red/Amber | Firmware corruption or Boot failure |
Reolink | Rapid Red | Low battery or Power shortage |
Hikvision | Alternating Red/Blue | Firmware update in progress |
Eufy | Blinking Red | Battery low / Needs recharge |
Quick Troubleshooting Steps
Before calling for a replacement, try these steps in order:
The 30-Second Power Cycle: Unplug the camera from its power source for 30 seconds. This clears the temporary memory and forces a fresh boot.
Test the Outlet: Plug a different device (like a lamp or phone charger) into the same outlet to ensure the problem isn't a tripped breaker.
Swap the Adapter: If you have multiple cameras, swap the power adapter of the "broken" camera with one that is working. If the camera starts working, you just need a new $15 adapter.
Check the "Night Mode" Draw: Cover the camera lens with your hand to simulate darkness. If the light starts blinking only when the IR lights try to click on, your power supply is definitely too weak.
Reset to Factory: Most cameras have a pinhole reset button. Hold it for 10–15 seconds to wipe the settings and try a fresh setup via your app.
When to Call the Professionals
If you’ve tried the steps above and your camera is still stuck in a blinking loop, it may be a sign of deeper wiring issues, a failed image sensor, or a localized power surge that damaged the internal circuitry.
