port number of a connection request coming in on its WAN port and forwards the
connection request to the appropriate IP address through its LAN port.
When you connect to iCVRs through the internet or across a WAN, your IT man-
ager must configure the routers connected to the iCVRs for port forwarding. The
following ports are used for each iCVR:
Aiming the Camera for Best Performance
Selecting the right field of view will make a significant difference in performance.
The key factors to consider when positioning an iCVR are:
Object Size:
In order for an object to be accurately classified, its height
should be greater than 20 pixels (about 1/20th the height of the image)
and less than 320 pixels (about 2/3rd the height of the image).
Expected Object Velocity:
The iCVR needs to be able to observe a
moving object for approximately 2 seconds before classifying it. Fast
moving vehicles might require a wider field of view so that the iCVR is
able to observe them for more than a few frames.
Blockages:
An object needs to appear unblocked for several frames in
order for its classification to be accurate. When the iCVR is used
outdoors, it is acceptable for an object to be blocked during some part of
the time that it’s in the field of view, but a full view of the object is
necessary for a good fraction of that time. When the iCVR is configured
for indoor analytics, it can detect the head and shoulders of a person.
Angle and Perspective:
The iCVR expects the ground plane to be
roughly horizontal, i.e., people walking in the field of view are mostly
upright and don’t appear to be tilted due to perspective distortion. The
