Main Reasons For Red Flashing
A red light on your Blink camera usually points to a problem. Here are the most common causes:
1. Wi-fi Connection Lost
When your camera can’t connect to the internet, it flashes red. For example, if your router is off or the Wi-Fi signal is weak, your Blink camera struggles to stay online. According to Blink support, over 60% of red light issues happen due to Wi-Fi failure.
2. Camera Setup Mode
During first-time setup or after a reset, the camera flashes red to show it’s ready for pairing. This is normal and stops once the camera connects to your app and Wi-Fi.
3. Battery Low Or Dead
If the batteries are drained, your Blink camera may flash red as a warning. Blink recommends using AA lithium batteries for best performance.
4. Firmware Update
Sometimes, the red light appears briefly during a software update. This usually stops after a few minutes.
5. Motion Detection Alert
Blink cameras also flash red when they detect motion and record. It’s a quick blink, not a constant flash.
How To Fix The Red Light Issue
If your Blink camera flashing red does not stop, try these steps:
1. Check Wi-fi Signal
Move your camera closer to the router or use a Wi-Fi extender. The ideal signal strength is above -60 dBm.
2. Replace Batteries
Put in fresh AA lithium batteries. Avoid using alkaline or rechargeable types.
3. Restart Camera
Turn off the camera, wait 30 seconds, then turn it back on.
4. Reset And Reconnect
Press the reset button (usually found on the back) for 5 seconds. Reconnect to your Blink app.
5. Update Firmware
Make sure your Blink app is updated. The camera will update firmware automatically if connected.
