The Solar ANPR trailers are starting to be used in Australia. The first company to adopt the technology, Aero Ranger, deployed its trailers from Bunbury up to Exmouth where it will monitor roads for traffic volumes, demographics, and origin/destination surveys as well as enforcement research. This is an excellent example of how solar power can help keep your CCTV camera running without having any wiring required!
This type of technology is perfect for places like highways where it would be very difficult to set up poles or other equipment without disrupting traffic flow. Solar panels on the ANPR trailer allow these cameras to run 24 hours a day without interruption and have been shown to last over 10 years!
