e. NVR throughput:
1) Server throughput shall be the capacity of the server to process
incoming and recorded video. This shall be a function of the processing
power of the NVR/server.
2) It shall provide for processing, remote viewing and recording capacity
to record on all cameras at:
i. Interior Cameras
a) Assume recording on movement rates of 50%.
b) Compression shall be no higher than 30%
c) 15 frames per second on all cameras during motion
ii. Exterior Cameras
a) Assume recording on movement rates of 50%.
b) Compression shall be no higher than 30%
c) Additionally, each exterior camera shall record 1 frame
per second when there is no motion.
d) 15 frames per second on all cameras during motion
iii. 5 users viewing 16 cameras each
iv. 5 user viewing up to 8 cameras mobile.
v. 5 users viewing cameras through a wireless smartphone or
tablet device
3) Thoughput shall be calculated at maximum camera resolution of the
specified cameras. Any spare throughput required shall be calculated
for cameras at 1280x960.
4) Throughput shall include processing of the cameras shown plus future
additional cameras as noted on the detailed drawings.
5) Assume that the owner will be viewing live video on 10% of the
installed cameras. This shall be taken into account if the server does
any processing of the live images.
6) Assume the owner will be viewing recorded video on 5% of the
cameras. This shall be taken into account if the server does any
processing of the recorded images during playback.
f. Video image storage: This shall include the amount of disk storage space
required to store all the images from the cameras. Storage space shall be
calculated based on:
i. Interior Cameras
e) Assume recording on movement rates of 50%.
f) Compression shall be no higher than 30%
g) 15 frames per second on all cameras during motion
ii. Exterior Cameras
h) Assume recording on movement rates of 50%.
i) Compression shall be no higher than 30%
j) Additionally, each exterior camera shall record 1 frame
per second when there is no motion.
k) 15 frames per second on all cameras during motion
2) Storage for 30 days.
3) Storing images at maximum camera resolution of the specified
cameras. Any spare storage required shall be calculated for cameras at
1280x960.
4) Include processing of the cameras shown plus future additional
cameras noted on the drawings.
g. Total Capacity shall be calculated by Contractor. Provide calculations if you
are asked to present your solution or if you are the chosen bidder.
h. Hard drives shall be internal or part of an external storage array. All discs shall
be configured in a RAID 5 redundant style array such that losing any single
drive will not mean a loss of recorded images.
