Camera Speed (throughput)
NOTE: The Adept SmartVision EX can support a total of four cameras.
GigE
A standalone Adept SmartVision EX (not connected to a SmartController or network) can
have up to four Ethernet ports: two are built-in, and two are possible with two GigE
expansion cards. The Adept SmartVision EX unit makes no distinction between the
different Ethernet ports. Four ports will support up to four cameras at the full GigE speed
of 1000 Mbit/s each.
An Adept SmartVision EX that is connected to a SmartController or network will have
one built-in Ethernet port available, and one more for each GigE expansion card in the
unit.
If a switch is used to add more cameras, the 1000 Mbit/s will be shared between all
cameras being serviced by each port. Two cameras on one port can run at a maximum
speed of 500 Mbit/s each, and so on.
1394b
Each 1394b expansion card has three ports. The total capacity of each card is 800 Mbit/s,
which is divided between the number of cameras using that card. The fastest throughput
per camera is obtained with one camera per card, yielding the full 800 Mbit/s for each
camera. Two cameras on one card can operate at 400 Mbit/s each, and so on.
Adding a second 1394b card adds another 800 Mbit/s of bandwidth, which can be
divided between the cameras connected to that card.
1394a
Each 1394a expansion card has two ports. The total capacity of each card is 400 Mbit/s,
which is divided between the number of cameras using that card. The fastest throughput
is obtained with one camera per card, yielding the full 400 Mbit/s for each camera. Two
cameras on one card can operate at a maximum speed of 200 Mbit/s each.
Adding a second 1394a card adds another 400 Mbit/s of bandwidth, which can be divided
between the cameras connected to that card.
