Never Miss Another Vehicle

In|Sync:Thermal brings mission-critical military technology to adaptive traffic signal camera solutions. Even in poor visibility conditions — including low light, fog, glare, rain, shadows and low vehicle-to-pavement contrast — In|Sync:Thermal’s traffic detector camera provides accurate and reliable imaging to help In|Sync improve traffic flow. By using a thermal signature, the system brings a higher level of accuracy to adaptive operations in environments that pose challenges to traditional video detection.

Poor Visibility Can Cause Detection Issues

Environmental Conditions Lead to False Data

Severe weather conditions, such as rain, snow, hail and even shadows, can fool a traditional traffic signal camera into thinking that vehicles are present when they’re not. Phenomena such as fog, sun glare and changing light hamper a standard video camera’s ability to detect vehicle presence. Even headlights can prove confusing to video cameras, leading to many real-life vehicles not being counted.

Video Cameras Are Inherently Unreliable

Standard video detection systems use a method called “background subtraction,” which is based on the comparison of a static background image with real-time images captured by a live camera feed. The processing software then tries to determine whether detected pixels are substantial enough to constitute vehicles — a highly approximate and unreliable method.

Not All Thermal Cameras Are Created Equal

Older thermal camera systems have experienced issues when the traffic camera is aimed directly at the sun (for example, when the sun moves through the field of view of a fixed camera pointed at the horizon). This has led to “fried” sensors and serious functionality problems.

How In|Sync:Thermal Works

Receive Higher Accuracy Through Heat Signature

Heat signature detection and thermal imaging eliminate errors that arise from the inability to reliably detect objects in low-light and severe weather conditions. In|Sync:Thermal’s traffic detectors convert the heat signatures of objects at an intersection into visible images which can be analyzed by the In|Sync Processor — detecting vehicle presence, real-time vehicle queue and delay information. In|Sync:Thermal sensors use millions of temperature probes — called Vanadium Oxide uncooled microbolometers — to detect heat signatures, resulting in extremely accurate vehicle detection.

Be Prepared for the Harshest Environments

In|Sync:Thermal’s cameras meet all NEMA temperature specifications, as well as protect against dust and water. The sensors are designed for long-term exposure to the sun and other harsh elements; using shortpass filters, the camera blocks wavelengths shorter than 7 micrometers, preventing damage from direct exposure to the sun. Each detector has an anti-reflective coating on its surface and comes with an optional sunshield.

Easy Installation and Minimal Maintenance Required

In|Sync:Thermal cameras use the same mechanical hardware, mounting arms and cabling as other Rhythm Engineering cameras. Power and network connectivity is easily established using PoE. Cleaning the detector’s lens is typically unnecessary. Even if dirt, salt or water droplets do accumulate on the detector’s lens, the particles will be out of focus and will not obscure the thermal image.

Use High-End Lenses to Match Each Intersection’s Needs

Several lens options are available for In|Sync:Thermal’s traffic detectors, from 7.5 mm to 35 mm, depending on the needs at each intersection and approach — such as longer lenses that offer a narrower field of view for better long-distance detection. Rhythm staff work with industry partners to ensure the proper lenses are selected.
