VIS-CAM Systems

The TLS-300 light sensor is an essential component that ensures the VIS cameras will be ready to capture high
quality images of any vehicle and its license plate in virtually all weather and light conditions.
It is very important to ensure that sensor positioning closely resembles real road conditions where the vehicle
image is most likely to be captured.
The light sensor is connected by means of the J-Panel VJP-300 and an RS485-to-Ethernet converter to the
Ethernet switch.
1.3.2 VISCAM
The VISCAM uses a state-of-the-art progressive interline transfer CCD that captures all of the vertical resolution
at once, thereby eliminating field-to-field imaging delays. The use of progressive scanning allows the camera to
freeze the motion of a rapidly moving vehicle at high resolution.
The VISCAM 300 houses a JAI TS-9720EN, the VISCAM 350 houses a JAI TS-1327EN, the VISCAM 400 houses the
TS-2030EN, and the VISCAM 500 houses a TS-4032EN Ethernet camera with a built in IBM Power PC using an
embedded Linux O/S for various operations, such as frame store, JPEG compression, vehicle fingerprint
extraction, license plate find, running applications, and so on.
When the TLS-300 Traffic Light Sensor is used to control the VISCAM exposure settings, no moving parts (such as
an auto-iris lens) are included in the VIS system. This helps ensure high reliability for the system.
A 12.5 mm to 75 mm manual zoom lens is provided as a standard with the VISCAM 300. This allows the VISCAM
to be mounted in a wide range of positions while ensuring sufficient resolution on the vehicle license plates. A
35 mm fixed focal length lens is provided standard with the VISCAM 400. A zoom lens is also available as an
option. An anti-glare polarizing filter is mounted in front of the lens to reduce smear in the picture caused by
sun glints. A 50 mm fixed focal lens is provided standard with the VISCAM 500.
