- Calculate
network traffic generated by digital (IP) cameras and video
encoders for the proper design of network CCTV systems.
- Calculate
disk space required for storing video archives during a specified
time.
- Calculation
can be carried out for cameras that generate up to 3 simultaneous
video streams (Viewing, Recording, Alarm recording)
with different resolution, compression, frame rate and recording
time.
- Calculation
can be carried out for a single camera, all cameras in the project,
as well as for isolated groups of cameras, that is useful to
estimate the load of separate network segments or equipment.
Filtering and sorting are possible in the Table.
- It
is possible to correct intermediate results
of calculations (frame size, traffic) if you know more accurate
experimental data.
- Calculations
are based on practical results of measuring traffic.
The results are combined in the Calculation Patterns, which
are editable text files. Special patterns can be created by
skilled users or manufacturers (distributors) of CCTV equipment
by practical measurements of traffic for certain equipment,
scenes and compression algorithms. Different cameras in one
project can be assigned different patterns. The patterns can
include a list of supported camera models. If any model from
the list is assigned to a camera in the table, then calculation
for the camera performs according to the pattern. Thus the maximum
possible calculation accuracy can be achieved. The patterns
can contain results of traffic measurements for some averaged
scene with correction factors for its complexity and activity,
and the results of traffic measurement for real scenes.
- CCTVCAD
Calculator can work with different sets of input data,
depending on their availability and required accuracy. Default
values will be assigned to unused fields. Unused columns in
the table can be hidden and excluded from the calculation. Created
Table Views can be saved and restored when needed. Thus CCTVCAD
Calculator can be a simple calculator for simplified calculation
only one stream from cameras, and a complex calculator, which
takes into account three independent streams, color, sound,
scene features, compression algorithm and hardware in use.
- Source
list of cameras can be entered manually or imported
from VideoCAD project file, from VideoCAD, installed
on the same computer or copied from MS Excel
table.
- Table
of results or its fragments can be printed
or exported to the formats: *. txt, *. csv, *. htm,
*. rtf, *. xls.
