Camera Label
The camera label indicates which camera is currently being viewed, along with other important system
information.
Camera Label Elements:
1 Camera - This part of the camera label tells the user that we are looking at camera one. "2 Camera"
would signify camera two.
C3 - This part of the camera label tells us that configuration three is the current active configuration.
"C1" would indicate configuration one, "C2" would indicate configuration two.
Algorithm Data Buffers
The buffers collect specific information about the intersection and allow the Vantage system to operate in a
more intelligent manner. Typically, an even greater level of system operational stability is achieved after both
buffers have been filled. If power is disrupted to the VersiCam Camera Processor module all the buffers will
be reset.
• DS – Day Short, processor in Day time mode and powered up for 0 to 2 days.
• NS – Night Short, processor in Night time mode and powered up for 0 to 2 days.
• D – Day, processor in Day time mode and powered up for more than 2 days.
• N – Night, processor in Night time mode and powered up for more than 2 days.
5.2 Three Stage System Operation
The following information is a high level look at the Vantage Three Stage System. This section is designed to
give the user further insight into their Vantage Edge2 processor operation.
The following system was being used in VersiCam firmware version 08.01.17, the current
VersiCam
firmware version at the time of this manual's publication. The following section is
somewhat firmware dependent and may change in future firmware versions. Always refer to the
current Vantage firmware release notes for the latest information on Vantage firmware features and
operation.
System operation is broken down into three stages. Each stage is by zone, different zones can be in different
stages depending on the road conditions for the zone. For example, some zones may be experiencing glare or
shadows when others are not.
Stage 1 (S1) - This stage indicates that the system is in normal operation. Detection should be occurring
normally, contrast and field of view image quality is good.
Stage 2 (S2) - This stage indicates a degradation of contrast and or field of view image quality. These
conditions usually accompany a decrease in detection strength (weak detections). These conditions trigger
the algorithm for increased sensitivity to ensure good detection. This increased sensitivity mode is known
as "Hypersensitive" mode.
