VISCAM 1000 Systems
2 Introduction
1.2.1 VISCAM 1000 System
The VISCAM 1000 uses a state-of-the-art camera system that freezes the motion of a rapidly moving vehicle
at high resolution, a zoom-lens or fixed focal length lens, and an on-axis illuminator, a weatherproof
housing with sun shield, heater resistors, I/O board, and a pan-tilt-roll mounting bracket. See Figure 2.
The VISCAM 1000 (All-In-One) features an optional embedded JAI trigger/light sensor for image triggering
and image contrast control. It also features an optional embedded LED-1000 illuminator (infrared, white or
blue) for independent 24/7 operation and excellent license plate contrast.
1.2.2 External Traffic Light Sensor – TLS-301 (optional)
The JAI Traffic Light Sensor TLS-301 provides an option to using VISCAM 1000’s built-in light sensing
capabilities described in Section 4.10.3. The TLS-301 estimates vehicles’ license plate lighting conditions
and controls the exposure and gain parameters of each camera to ensure high contrast images of vehicles
traveling through the field of view and their license plates, regardless of vehicle speed, weather or
ambient light conditions. For more information about the TLS-301, see Appendix B at the end of this
document.
1.2.3 External Light Sources
JAI offers a full lineup of lighting solutions optimized for a large number of applications.
The TNF-35 Traffic Night Flash unit is a 17W, long-life flash with an effective life span of up to 4 million
flashes. It comes in various application specific configurations for emission spectrum. With the standard
filter it generates light in wavelengths that are invisible to the human eye, but visible to the camera. For
more information about the TNF-35, see Appendix C at the end of this document.
The TNL-50 is a newer, high-performance LED Flash intended for traffic applications, including automated
number plate reading systems. The TNL-50 is field proven to produce high-contrast images of passing
vehicles and their number plates. With its very high light output, versatility, ease of installation and its
compact size, it makes it easy to see why it is an industry leading illumination solution. It also comes in
three configurations, broadband white, NIR, and blue to support various applications. Additional
information about installing and configuring the TNL-50 can be found in Sections 3.3 and 4.7 of this
document.
Both the TNL-50 and TNF-35 are automatically enabled whenever the camera or the optional TLS-301 Light
Sensor determines that ambient light is insufficient to produce a picture of usable quality.
1.2.4 Embedded Light Sources (LED-1000 IR, white or blue)
Various applications require the use of an embedded illuminator. JAI offers the LED-1000 illuminator with
infrared, white, or blue LEDs. See Figure 2.
1.2.5 VJP-300 Junction Panel
The J-Panel is the central connection point for the VIS components. The J-Panel is a DIN-Rail mounted PCB
(printed circuit board) equipped with various interface terminals for interconnection. Each J-panel can
support up to two VISCAM systems.
1.2.6 Optional 24V DC Power Supply
JAI provides a robust industrial rated power supply.
1.2.7 Optional gigabit Ethernet switch
JAI recommends using a field-proven industrial rated gigabit Ethernet switch.
1.2.8 System interconnection cables
JAI supplies a cabling solution that has proven its reliability on a large number of installation sites.
