Revolution of Traffic Monitoring: How Did ANPR Cameras Evolve Through Time?

Automatic Number Reading has Evolved Significantly in Recent Years

The automatic number plate reading system was introduced at the end of the 90s’. They were in fact some of the first applications of artificial intelligence in the field of Intelligent Transportation Systems. The first of such camera systems could read the license plate of moving vehicles. Their computation capabilities were modest as the hardware and software at the time were basic yet expensive. Though there were cheaper options available, they were not all compatible to be used for access control.

Evolution of ANPR 

Over time as more and more development was done in this sector, both the hardware and software technologies rapidly evolved. Since then the possibility to use commercial processing systems with a normal or good quality video surveillance camera became a norm in many countries. As the cost of installing and acquiring them also reduced substantially, these cameras were used in a number of industries and fields. 

Since then these cameras have only seen a growth in demand. With good ANPR cameras, traffic monitoring has been revolutionized. These can provide access control, parking management, border control, toll payments, speed control, and law violation control. The law enforcers can currently benefit from this application as it provides a spread of geolocation technologies as well as a centralized database option. 

Vehicles can be monitored easily in the traffic through a web page as well as from mobile devices. This helps the traffic police officers to get immediate notification if there has been any violation of law by a vehicle driver like crossing the red light, exceeding the speed limit, or bigger crimes like theft of vehicles or hit and run incidents. 

How Does it Work?

The architecture of these surveillance cameras has pretty much remained the same but the software has been updated continuously. The plate recognition takes place with the help of the use of software that is being run on powerful computers. These back-end computers analyze the video streams and distribute them to the front end for monitoring. These systems are limited only due to the high bandwidth demand as well as an increase in the power needed to process the frames. This is because the frames consist of millions of pixels. The company’s that make these cameras then started to miniaturize and increase the power of the processing unit in order to find a solution. 

In some commercial properties, the ANPR is usually placed at the entrance and exit of car parks. They are used for capturing and processing the details of all the vehicles that enter or exit the building. If there is an unauthorized vehicle entering the building, then the license number of that car is identified and stored. The same goes for if anyone exceeds the speed limit on parking lots or parks their vehicle for a very long time in the parking lot and breeches the stay period. In these cases, the license plate number is recognized and the driver gets a fine via post or on this mobile. For commercial properties, these give them an ideal solution to solve the problem of everyone who is trying to use their parking lot as a free facility. These cameras can not only capture the details of all the vehicles in the daylight but also in the dark at night. 

Furthermore, when you use these cameras for your business property, then you can decrease the cost of installing a manual parking system as well as labor costs. By providing all the employees with a touch screen pay option as well as display machines, their vehicles will easily be identified by the camera and allow them to enter. As the system is fully automated you will eliminate the need for every driver to display a ticket to enter. 

Future of ANPR

As more and more industries make sure of these surveillance cameras to maintain safety and security on their property, the future of ANPR seems to be bright. There is an ever-growing demand for these as businesses and law enforcement try to maintain control over car park control and management, airport security, journey time management, transport and logistics, and traffic surveys.

While these cameras continuously upgrade the use of their technology to be able to make it more smarted, there are still some challenges that need to be overcome. These cameras have given rise to a new kind of criminal activity called car cloning. In such crimes, the number plates are copied so that when they are read by such systems, they will identify fake license plate numbers. However, with the innovation and technology galloping at the fastest pace than it ever hard, it won’t be long before these challenges are overcome as well. 

Tips for Creating and Video Editing Slow Motion Content for iPhone

Bloggers and content makers need creative options to attract the audience with stunning solutions. If you are searching for an interesting way to enrich your content, try slow motion videos. They help to highlight a specific video fragment and match slow music flawlessly. This editing feature can evoke different emotions depending on what you want to achieve: surprise, amazement, calm, sadness, etc. With slow motion, you have unlimited possibilities, but how to bring them to life? There is no need for professional equipment, and your smartphone can help you with the task of creating a slow motion video. In this article, you will learn how to make a video slow motion on an iPhone. Let’s discover more useful information for stunning results! 

Slow Motion Work Principles

Let’s consider this notion from a technical viewpoint. We know that a video consists of a sequence of photos, and their fast representation provides an image of movement. It may seem weird, but to create a slow motion video, you need to have a high-speed camera. The reason behind this contradiction is that most video cameras record about 30 frames per second. However, this speed is considered to be slow for a slow motion video, and many details will be omitted. The slow motion video provides unusual images, and viewers do not expect to see a detailed presentation of a usual video. Sometimes it may seem that the video is freezing, smoothly changing one frame to another. 

With a high-speed camera, you can benefit from over 2,000 frames per second. These numbers are impressive, and you should try them on your own. It will be possible to take a closer look at details that are usually invisible at a normal video speed. The slow motion effect will surprise the audience and give them an unforgettable viewing experience! 

How Does Slow Motion Work on Your iPhone? 

iPhone users benefit from a plethora of great features, but there are cases when its storage capacity is full, or you don’t know how to get rid of annoying advertising. The slo-mo feature on your iPhone allows you to shoot different scenes and make them more fascinating. When you shoot a slow motion video on your iPhone, you are playing back the video at a slower frame rate.  It creates the illusion of a slow video. This feature is standard and is accessible in the Camera app. It is located in the menu above the shutter button. There is also a possibility to change a slo-mo video to a normal speed. Open the Edit icon and choose a slider at the bottom of your screen that will make the video speed regular. You can change the speed of a part of your video, making it more versatile and astonishing. 

Let’s consider the iPhone X’s camera for diving into this issue. This model is one of the most popular on the market, therefore, it will be useful to explore its camera characteristics.
