Is there a way to filter out the IR LED red glow?

As a baby monitor mounted inside the box of a robot, the red glow of the IR cans appears very ominous to my child.

I am using [CAM008](https://shop.pimoroni.com/products/night-vision-camera-module-for-raspberry-pi?variant=12516582752339) setup as a DIY baby camera running `picamera` on a Raspberry Pi Zero 1 W.

Based on datasheets, the wavelength of the IR is 850nm. Therefore, I have attempted to filter out the visible red light with 850nm IR glass filters such as with the [Linghuang ZOMEI IR 850nm 25mm Art Glass Infrared Filter](https://www.amazon.de/gp/product/B08Z79SH8W). The red glow is reduced but still visible at night.

Any solution for the baby monitor use case? If not, a workaround could be to only fire the emitters camera exposure is active and/or when someone is remotely viewing the camera feed.
