Can you move the camera to the edge of the table or elevate it somehow? What’s happening is that the camera is trying to expose the whole picture based in the IR hotspot on the table top immediately in front of the camera, therefore underexposing the background. Once you re-aim the camera and everything in the room is equal distant to the camera it should expose it better.
Very normal - until you follow @Omgitstony 's excellent advice.
I well remember running into this quite a bit until I learned to hang cameras over the edges of things, and then always double check them in the dark before leaving town.
Pretty soon you’ll be filming “flying centipedes” with the best of 'em!
