Webcam time lapse

Hi, i want to put a second webcam outside & have it make time lapse videos the same as WD does or similar , this is nothing to do with the weather station. I’m thinking of using a logitech C920 webcam, I do have a olympus sp 500uz & I was going to use “sebec tec” software but I cannot get into the camera software to make it work ( anyone know how to do this ), so what I’m after is some free/cheap software that does the same as the software in WD, can help me please.

many thanks.
