Are you having trouble with your Blink Camera?

Have you noticed that your camera is not detecting any motion despite the fact you have turned it on and all of the settings are correct? If yes, you are not alone, and in this guide, I will share my research with you.

I was facing the same issue, and after spending a few hours online, I found some solutions that will help you resolve the issue ASAP.

Blink camera not Detecting Motion – Causes

Based on my research and technical analysis, there are several reasons why this may occur.

  • Firstly, the placement of the camera may be unsuitable for motion detection. You should place the cam in a position that provides a clear and unobstructed view of the area.
  • Additionally, the camera may not have been armed or disarmed unknowingly, which can prevent it from detecting motion.
  • Another common cause is low battery power, as the camera requires significant energy to function correctly.
  • Lastly, a weak Wi-Fi signal or connectivity issues could be the reason for motion detection failure.

With that said, let’s get to the solutions!

1. Enable Motion Detection from the App

Let us start by enabling the motion detection feature via the mobile app. Here are the steps:

  1. Open the Blink app on your smartphone or tablet.
  2. Select the camera that you want to enable motion detection for.
