Configuration

Overview

The TrafficVisionTMC software must have access to one or more cameras for processing.

The term Camera actually refers to a digital input from a traffic-monitoring camera.

This video input may be live or previously recorded:

A live camera, connected over a network or directly attached to the system (some TMC Remote models only), provides a real-time video stream.
A recorded camera is a digital video file for playback. Digital video file formats supported by the TMC include MPEG, MPEG-2, MPEG-4, M-JPEG and H.264.

Camera Configuration is the process of:

Connecting a camera and its video input to the TMC system
Calibrating the video input with visual overlays that define distance, scale and boundaries for traffic and incident monitoring
Activating data collection by the camera

With TrafficVision’s AutoLearn feature, it is not necessary to calibrate a camera to obtain traffic data from that camera. However, more data retrieval is possible when a camera is manually calibrated.

Required Information

To add and configure a camera, you enter profile information unique to that camera. You should be able to get this information from the TMC Web Application (or TMC system) administrator. Here is a list of the kind of information you will need:

Task	Subject	Required Information
Adding a Camera	Input method	Specify whether a camera provides live video feed via network connection or is recorded to a digital file. You need the network address for each networked camera. You need the file name for a recorded file, and the TMC system owner or administrator must make the file available.
Adding a TMC Turnkey Appliance or Virtual Machine	TMC system network address	When adding one or more TMC systems (to view more cameras in one Web Application), you need the network address for each system.
Administrator user name and password	You must have an admin account type to add a TMC system to the Web Application. Your user name and password are required to verify this.
Calibrating a Camera	Lane width	A known distance according to local roadway standards.
Known length	A known distance that you can manually plot on the camera view.
You can independently measure exact length in the camera view. Example: Set up two traffic cones in a camera’s view separated by a known distance.
