General Description
One MigmaIntersection™ unit comprises of one Single
Board Computer (SBC) and two stereo cameras. Each SBC
needs to be placed inside a cabinet. The two stereo
cameras should be mounted to the existing signal poles or
pedestals at a desired height above the ground, typically 15
- 20 ft.
Camera Wiring
Unscrew the waterproof Ethernet connector at the back of
the stereo camera, carefully push the Cat5e cable through
the connector, and then crimp the RJ45 connector to the
Cat5e cable. Now screw back the connector and tighten it.
Please note that the wiring scheme of RJ45 connector
follows T-568B.
Mount the cameras on the signal poles. Mark the Cat5e
cable connected to each camera as “System 1” or “System
2”. At the back of SBC, there are two RJ45 connectors.
Connect Cat5e cable marked as “System 1” to RJ45
connector labeled as “Sys 1”. Similarly connect Cat5e
cable marked as “System 2” to the connector labeled as
