Off-angle illumination for better enforcement

The TNL-25 is designed to complement on-axis ring lighting used to illuminate number plates in dark conditions. Its bright, yet diffuse illumination makes sure that the entire vehicle and surrounding details are also properly exposed for a more complete and indisputable enforcement package.

Small size perfect for side-fire applications

At only 4-1/4 inches wide and less than 6 inches high, this compact unit mounts easily on poles, walls, or other structures to provide side-fire lighting for stationary, slow-speed, or other close-in geometries.

Multiple spectral options

With wavelength options including NIR (850nm), blue (470nm), and white (visible spectrum), the TNL-25 can be configured to support the highest possible automated read rates regardless of time-of-day or number plate color schemes.

Features

  • High powered, compact size, and lightweight LED flash unit.

  • Provides off-angle illumination of vehicles and scene details.

  • Designed for side-fire and slow-speed applications.

  • Up to 75 Hz for traffic bursts & image sequences.

  • Near infrared (invisible), white, or blue spectral combinations.

  • Field proven IP66 and IK07 enclosure for long-life operation.

  • Can be used with JAI or third-party vehicle imaging systems.

Here are a few applications where TNL-25 systems are especially suitable

TNL-25 LED flash systems can be configured for a variety of ITS applications.

Toll collection and violation enforcement

At traditional toll booths, TNL-25 complements LED ring lighting to provide the off-axis illumination needed to ensure proper exposure of vehicles in all lighting conditions.

Border and access control

TNL-25 provides reliable 24/7 operation for monitoring border crossings or for vehicle identification prior to granting access to restricted facilities.

Weigh-in-motion systems

For integrators implementing weigh-in-motion systems, TNL-25 ensures that reliable plate and vehicle images of large vehicles can be captured day or night at normal traffic speeds to maximize the efficiency of transport.

Congestion charging

TNL-25 can help capture plate and vehicle images of road users who congest specific areas and/or times to support initiatives that encourage smarter driving habits and the use of public transportation.

Parking Lots

Low power, lower cost configuration makes the TNL-25 well-suited to parking lot scenarios or other applications involving stopped vehicles and/or shorter lighting distances.
