We are trying to track the behavior of the fish Chromis virdis during the night.
since the fish are hiding inside corals (Acropora) I might need to place several cameras around the coral. Therefore I'm looking for recommendation for cheep IR camera that still have good enough quality (sew some drop fishing cameras that might be suitable, does anyone have experience using something like that?) or maybe other ideas for recording systems?
Normally, the cameras with the highest dynamic range are usually the most expensive on the market, which can make you believe that you have to spend many thousands of euros to make good HDR photos, something that is not true at all. Without a doubt, a camera of that price will make very good pictures if you know how to get the most out of it, but it is not necessary to spend so much money to take HDR photos. But what you are looking for is to record so a camera with good HDR is not so necessary. We can assess offers: 1.

Now if you ask me which I choose taking into account a minimum installation of 4 cameras option 2 is very good, but if I take into account that the longest activity time on a reef is at night because the best I think would be option 3. All It depends on how much money you can spend
In my experience I have used the GoPro are small easy to manipulate and install, very easy to mask, I used to evaluate the daily cycle in Chitones.
From my experience having more than 20,000 underwater in research, i believed the Canon WPDC36 40m; IXUS 105 IS, it can work for your particular task. (please inspect the specs)
Asiel Cabrera Guerrero I don't see an infrared option in any of them. Did you add external light for using them at night?
Yes, you must add external light that is as white as possible, no yellow, and if it can be led better, remember that light can attract them to a behavior that is not the general one, therefore, it should be as white as possible. the light that reflects the moon!
As per my previous reply you can obtain an underwater case whereas you can add the infrared.
