I have three cameras. They are on continuous video and each snap a photo a second. All is set to store on my terabyte drive with plenty of space. I have the folder settings for over 1000 gb. For some reason, all recording stops after working properly for hours. How do I fix this? I have no schedule so no reason for them to stop. Maybe I don't have the settings right - how do you direct all clips and recordings to record on an external drive? They work for about6 hours and quit.
