What Camera Can Take Night Video?

Our classroom has a webcam so we can view our tank and I can keep an eye on the sump area after hours. It would be great if we could observe what our corals look like during the night! Anybody have any experience with this?

 

I use a raspberry pi controller with noir camera. It's infra red based night camera, u'll loose the colors, but can observe fish/shrimp interaction and snails activity ..

 

Never thought about using Raspberry pi and can find out about noir camera. I have students who could do that for a project in their tech class. I had a funding opportunity so got a random webcam that had good Amazon reviews. We'll see how it is in January. Thanks @Ranjib Dey
