Using 2 IPC-HDW2231R-ZS starlight outdoor cam's recording continuous. I have the clips set to 4 hrs before creating a new clip. With little to no activity the 4 hr clip is usually around 6 gb each. My indoor cameras average around 3-5 gb w/ a lot of activity. All cameras are 1080p, is this normal? Indoor cameras are amcrest and foscam. Maybe just a picture quality difference?
