New to security camera systems? Confused by Analog vs IP? When use different method for record, the strogage time will be different. Motion detection recording means only record when video camera detect movement, then it will start to record, no motion, then no record. Record image quality means the video file size, low quality image will occupy less space, and extend more record time. High resolution quality images means big file size, it will occupy more storage space and with less record time.
When record video, DVR can select the record size or image size , record size changes the amount of data place in the harddrive. The big size of image, the less time DVR can record. For Harddrive, the bigger storage size of the drive, the longer of record time.

As mentioned the most common thing to go on them are the hard drives, which can be changed. Most have the power supply as a separate part so if that goes that can also be changed. Most stand alone DVRs are just really basic boards, nothing much on them to go bad.
Actually only had to change the hard drive once as it is on a voltage regulator, seems the hard drive just failed after several years. So if anyone has a DVR that you think that has went Kaput, try changing the hard-drive and see what that does. I have gotten some great deals on some brand name DVR's off of ebay that were listed as "for parts or not working" in which the user mistakenly thought that the DVR went bad, and all it was was a bad hard-drive.
Changed out the hard-drive and it was as good as new. I would also agree that the hard drive can often be an issue, even when the symptoms might not lead you to thinking the fault is a hard drive related one. Most people expect a hard drive fault to manifest it's self as the DVR switching on, displaying the cameras but not recording. What often happens is the DVR won't fire up at all because as it goes through it's check list when booting up it sees a problem with the hard drive and freezes or remains in a constant loop.
I pulled it out of storage about a year later to test it, found that it would lock up as soon as anything tried to access its search database I could make it lock consistently by going into the database settings.
