How to Build a DIY Night Vision Scope Out of an Old Webcam


Building your own night vision scope using a webcam can be a fun and rewarding DIY project. With just a few common materials, you can construct a device that allows you to see in low light conditions. In this guide, I will walk you through the full process of creating your own night vision webcam scope on a budget.

Gather the Necessary Materials

To build the night vision scope, you will need:

Disassemble the Webcam and Remove the IR Filter

The first step is to disassemble the webcam and locate the IR filter. This filter blocks infrared light, so it needs to be removed for the camera to see IR.

  1. Carefully disassemble the webcam case and locate the image sensor and lens assembly.
  2. Identify the small glass IR filter positioned over the image sensor. It will appear purple or blue in color.
  3. Use a small screwdriver to pry and remove the IR filter from the sensor. Be very gentle to avoid damaging the sensor.
  4. Reassemble the webcam without the filter. Make sure wires are connected and it functions normally.

Add Infrared LEDs for Illumination

With the filter removed, IR light can now reach the sensor. IR LEDs need to be added to provide illumination that the camera can detect.

Construct the Webcam Body

The webcam needs to be housed in a scope-like body with lenses for magnification:

Create a Visible Light Filter

The webcam sensor needs a filter to block visible light or else the image will be overwhelmed.
