Our standard DVR systems are capable of recording about 4 weeks on motion, by adding additional hard drives the capacity can be extended to several months. The general rule of thumb is that each camera will use about 2 to 3 gigabytes (gigs) of hard drive space a day. If you are using motion detection the hard drive usage will likely be less (especially if there is little movement on each camera). The actual amount of hard drive space used varies widely and depends to a large extent on how much movement there is on the cameras. For example, a PC-Based 4 camera 60fps system with 120 gigs of hard drive space will use about 8 to 12 gig total per day, giving you from 10 to 15 days of recordings before it needs to start writing over the old video.
