RESOLVED

The mod is called Docking Cams. It adds a single camera, "Onboard Camera" and is the exact camera I was looking for.

So there was this one mod that added a camera for KSP which brought up a UI, had CRT, NV, IR vision and stuff and was on gimbal. It wasn't from Hullcam VDS, and it also had a science experiment with it. The UI it brought up looked like the UI of the BDA targeting pods, and it also had zoom options, in addition to an additional digital zoom of x48. It had 4 yellow balls on the base of it and when right clicked to interact with it, the menu had a place that said "Shots Left: 4". I never figured out what that meant, however that's beside the point. Now after a new modpack, after I lost the old one, I just can not find the mod that added it. I had pictures I've taken using it but I also can't find those anymore, however I remember what it looked like so here is an illustration on what it looked like and a similar UI to the UI it had..
