For those who use a desktop what is your average CPU usage per camera? I just came onboard with a HIKvision DS-2CD2T42WD-I3 4MM cam. Its on a BlueIris package and the CPU usage is up and down from low teens to low 20s depending on what I have no idea. I am set to record only images and clips at what I think is the highest quality. Running a i5 3g processor I don't do a lot else with this machine other than surf and download movies etc per normal homeowners. Opening the Hikvision SAD package does double more or less what the cam is using on BI. I hope to add 2 more outdoor cams and an occasional indoor wireless for when we are gone.
