Portable speed camera


 Speed cameras are used for speed measurement: they are used by police as an anti-speeding camera to catch offending vehicles. S1 works differently: it records each passing vehicle, registers its speed and license plate, takes a full-color image, detects violation events, adds a time stamp and a location stamp and creates a data package which it stores and forwards to a central database. Unlike a handheld speed gun or a typical police speed control device which needs operating personnel, S1 is fully self-operated. Once set up on location, it uses automatic number plate recognition technology to identify vehicles, takes still images or video, deploys event recognition to record their behaviour in traffic, uses its integral GPS to add location data and does all this without human intervention. Recorded data can be used real-time or later by authorities or electronic toll collection staff. Besides fighting speeding, S1 is ideal as an enforcement camera to detect violations like driving in a bus lane or emergency lane and ignoring a no entry sign. S1 also functions as a traffic monitoring tool counting traffic and spotting congestion or traffic jams. S1 can even recognize ADR (Hazmat) codes. Since it is a laser speed camera, S1 makes radar detectors obsolete. Besides improving traffic safety, it can be used for monitoring by road traffic control or can be part of smart traffic management known as Intelligent Transportation System (ITS). In short, S1 is so much more than a speed measurement camera or even a mobile speed camera to stop drivers for speeding. Why? See benefits below.
  • highly reliable real-time identification of each passing vehicle
  • data package of each passing event available online or offline, including full-color vehicle image and license plate
  • works on a tripod or from inside vehicle
  • laser beam trigger unseen by radar detectors
  • registers traffic violation events like speeding, illegal lane use or ignoring a no entry or one-way sign
  • anti-fraud / anti-corruption / no tamper design

ARH S1 is ideal for:
  • traffic enforcement
  • speed enforcement

ARH S1 combines license plate recognition, a 30× optical zoom camera, IR and LED illumination, communication, GPS, data processing and certified laser speed detection capabilities in a single portable unit. Its built-in motion detection, JPEG image/MJPEG stream output, internal image buffer and H.264 compression can provide up to ten times smaller video stream, which leads to less network traffic and smaller storage space.
