Re: store system w 4-8 cameras ?

["Doug L" <vssdoug@xxxxxxx>]

I think the gaps he is referring to are caused by  motion recording, not a
lower recording rate. IE if someone stands still for 30 seconds and there is
no other motion in the view, when playing back the video it will appear that
there is a 30 second gap in the recording regardless if recording at 5pps or
30pps. .

IMNSHO anything over  three pps is adequate for general use, too many people
get hung up on high frame rates instead of the image quality, its probably
better to have a high quality image at 4 or 5pps per camera than 30pps of
low quality footage.  I normally set my systems to record continuously at
1pps increasing the rate when motion is detected

Quoting 30, 60 or 120pps without also mentioning the number of channels or
cameras is meaningless, since a 120pps 16channel machine will produce in
theory 7.5pps per camera, in a 4 channel machine it would be 30pps per
camera.

Generally speaking PC based machines are able to handle higher pps than
stand alones

As far as reliability is concerned, the hard drives can be the Achilles heel
of any system, in the old days a trashed tape would wipe out a days
recording, a hard drive crash in a DVR,( PC or standalone ), can take out a
month of video
