ABOUT THE CALCULATOR:


The Incident Capacity Calculator helps you determine how much data can be effectively moved from an Intellex to an Intellex Client. It does this on the basis of "incidents.”  An incident of given duration, camera rate, and settings quality will have a characteristic size, based on the motion descriptor.

ABOUT THE MOTION DESCRIPTORS:

  1. Minimum a quiet room or hallway with an occasional occupant(s) or traffic .  Virtually no motion or change due to wind, camera motion, or camera noise.
  2. Casual A room or hallway with couple of occupants or fairly frequent traffic.  A sidewalk or street with some traffic and little motion due to wind, light or camera noise.
  3. Moderate a busy room with several moving occupants or a busy hallway.  Several people moving at a time. A street or sidewalk with moderate traffic and/or moderate motion of trees and bushes due to wind.
  4. Severe Extreme motion caused by camera motion, or severe camera noise. A panning dome camera or severe wind motion in most of the image.

WHAT IS THE INCIDENT RECORD RATE?

It is the rate at which the camera was recording during an incident. For most alarm situations, you will be recording real time, which for a single camera alarm is 30/25 IPS. If you are doing time lapse, or have multiple cameras in alarm, you must take this into account. However for most real time incidents 30/25 IPS should do.

WHAT IS BANDWIDTH?

Many system administrators don't want you to consume the entire bandwidth of a link, and may even restrict a segment's performance. This field allows you to "degrade" the performance of the link accordingly.

WHY DON'T THE NUMBERS CHANGE ON LAN SETTINGS?

A LAN is typically a very high speed connection. An Intellex generally can deliver up to about 450 KBytes (3.6 Mbits) per second maximum. This is because it is doing LOTS of other stuff at the same time.  3.6 Mbits is only about 36% of a 10 base T network (smaller on others). So unless you degrade the link performance below 36% in 10 Base T settings, the LAN numbers won't change.

WHAT DO THE NUMBERS MEAN?

There are three basic numbers for each motion level:

  1. # Incidents: the number of incidents per hour you could theoretically download. This does not take into account operator interaction time, etc. It's more a theoretical maximum.
  2. Minutes of Video: the total number of minutes of video you can store, for an hour of download time On a low bandwidth link this number is low, unless you recorded at a low image rate. On a high bandwidth link, this number will be quite large.
  3. Storage: the number of Megabytes per hour you would consume on the client side uploading the incidents.
