Axis adds the Artpec-7 chip to its new P39-range on-board cameras

These devices represent the fifth generation of cameras on board the manufacturer, incorporating invisible infrared LEDs and advanced features to capture sharp images with low illumination.

The new models of on-board cameras Axis, the fifth generation developed by this manufacturer, try to respond to the challenges posed by the capture of video and audio of this type of devices.

The Axis P3935-LR model incorporates invisible infrared LEDs and offers sharp images in conditions of absolute darkness, which makes it ideal for installation in vehicles that move through rural locations, with poor night lighting, or where lighting inside the vehicle could be annoying for passengers.

The infrared LEDs of this new camera work on the upper wavelength of 940 Nm, so they will not appear as the red dots that are observed in traditional Led; this change means an improvement in the safety and comfort of both the driver and passengers.

The integration of other technologies from this manufacturer, such as Lightfinder and Forensic WDR, provides the camera with optimal performance in low light and intense backlight conditions, For example, when it receives strong direct sunlight.

For the first time, these on-board cameras include an accelerometer that, together with the integrated gyroscope, allow the use of electronic image stabilization (Electronic image stabilization, Eis) to capture sharp images of the vehicle's exterior in all environmental conditions.

In addition, for forward-facing cameras in fast-moving vehicles, the variable frame rate of the camera, up to 45 Fps, is a very valuable element to capture details, For example, if a train hits an obstacle on the track.

The use of the Artpec-7 chip has driven the transformation of analytics options. One of its main improvements, as they point out from the company, "it's their ability to use analytics in the camera itself and not on a server hosted in the data center.. This doesn't just mean that analytics-driven actions can be applied much faster., but it opens up endless opportunities for these applications.".

Other possibilities offered by analytics are people counting and passenger demographic analysis, that can provide valuable business information to transport authorities to optimise routes and services.

At this time they can also be used to reduce public health risks., For example, measuring the occupancy of the squares and controlling compliance with physical distancing measures. Appropriate analytics could also be used to monitor the top floor of a double-decker bus and alert the driver if a problem occurs or play an automatic ad..

The microphone built into one of the new cameras can also generate alerts that can be triggered by detecting verbal aggressions or voices with a stressful or distressing tone and, in this way, improve passenger safety.
