I have been using blue iris for the last few months and have 20+ cams recording 24hrs a day. there are 5 of them covering a area that leads to a side door. the other day i got an email for a cam alert when i viewed it i only seen a second or two and barely long enough for the brightness for the motion went away. so when i got home went to that alert and viewed all the cams at that time. the person never showed up anywhere just instantly at the door. the driveway is 150ft long and the only other way to the area is around the house which they would have passed several other cams. i have all the cams set at 1080p 15fps and a pre-buffer of 150 fps. anybody have ideas why nothing was captured until they were directly at the door? I don't understand being recording 24/7
Thanks
