Welcome To
ESLI's DVR
Storage Calculator
One
of the most overlooked upgrades
when purchasing a digital video recorder (DVR) is the size of the hard drive.
Fortunately,
our DVR Storage Calculator will help you determine what HD size is right for your
specific
situation.
Try several scenarios that best
fit your particular situation.
Bytes are measured through the
power of two's!
-
One gigabyte is two to the 30th power in bytes, equaling
1,073,741,824 bytes, or 1,048,576 kilobytes or 1,024 megabytes.
-
One half of 1,024
megabytes is 512, therefore, 512 megabytes is equal to one half of a gigabyte
and half of a terabyte is 512 gigabytes.
Let's Get Started!
FPS = Frames Per Second - DVR = Digital Video Recorder -
HD = Hard Drive
*If
the total FPS recording speed is
160 on your DVR
and, you have 16 cameras connected to
your system, you divide 160
÷ 16. Therefore Ten is
the response to the question "Frames per second on one camera"
**If your DVR is
set to record on motion, do not include days and/or hours when the
recording area is clear of traffic.
***Other factors may influence the DVR's hard drives storage capacity
as well as the number of days your DVR will store video. Most common are HD
compression and resolution. As with all advice listed on
eyespyli.com or other publications, we try to give you a starting point.
All CCTV jobs are different and individual needs have to be taken into
consideration. Please check with one of our trained representatives with your specific requirements before starting any job.
