🔄 Try this first — Unplug the Blink Arc power cable from the wall socket, wait 10 seconds, then plug it back in. Both cameras will restart automatically. Also restart your router by unplugging it for 30 seconds.

If your Blink Arc is showing this problem, working through the checks below in order will resolve it in the large majority of cases.

What This Problem Means

The Blink Arc is not detecting motion as expected. The camera uses a passive infrared (PIR) sensor to detect motion. When motion is missed, it is almost always a settings, sensitivity or positioning issue.

Common Symptoms

  • No motion alerts received despite activity on camera
  • Motion events not being recorded
  • Detection works sometimes but misses events at other times

Safe Checks You Can Try

1. Check motion detection is enabled

Open the app and confirm Motion Detection is switched on and notifications are enabled.

2. Adjust sensitivity and activity zones

Increase sensitivity in the app settings. Check your activity zones are covering the area you want monitored.

3. Check camera placement and angle

Sensors detect motion best when subjects move across the field of view rather than directly towards the camera. Angle the camera slightly if subjects are walking straight at the lens.

4. Check for interference

Nearby heat sources, direct sunlight or air conditioning can interfere with PIR detection.
