Cheap DIY babycam with night vision
When I did this project in 2012 babycams cost from NOK 2000 and up, so I decided to see if I could build one using a Raspberry Pi, an IR light and a very cheap webcam.
This will of course only be a level 0 night vision (active).
- IR LEDs with a 12V PSU.
- Raspberry Pi with a 5V PSU.
- Webcam. I don’t have a link to it, but pretty much any webcam will do.
I set up a test and was disappointed that the IR setup hardly gave any visible picture at all, so I threw it in the trash. Then I rememberd that all digital cameras have an IR filter to sharpen daylight pictures. To remove it I did this:
- Unscrew any lense or cover.
- Look for a small, slightly colored piece of glass covering the CMOS chip, and remove it by force.
Now the IR seemed to light up objects several meters away. As IR light can hurt eyes, I have the light pointed towards the ceiling, so only reflected light is ever hitting people.
- Installed raspbian.
- Installed motion.
- Webcam is now available to local network for PCs (browser, VLC) and phones (VLC, video streaming apps).
