How to use relay cameras to improve security and training

These devices offer a solution, at this very moment especially necessary, by providing an objective method of viewing and recording events remotely. Axis manufacturer looks at different forms and applications of use.

Technology has always intervened to 'shorten the distances' between people; either through the use of electronic communications, such as email or video message. The pandemic has been a unique challenge that has resulted in a decrease in the ability to care for people and situations in person, which has had a chain effect in different sectors, including, of course, health, education, sports, Etc.

The broadcast cameras have offered a much-needed solution, by providing an objective method of viewing and recording events remotely. This article describes the different ways these devices can help fulfill this feature in a number of apps.

Teaching teachers

Distance learning has become a fixed resource for education systems due to current restrictions arising from the pandemic and social estating.

However, before even the health crisis, educational authorities were looking for ways to improve teacher training. The observation of the classes has been a fundamental element of this process, but the presence of an evaluator in the classroom could condition the behaviors, so the result would not be representative.

Solutions capable of monitoring classrooms remotely are more effective, especially if they offer the option to play back the images.

An example of this is the University of Regensburg, in the German city of the same name, whose leaders faced this challenge around the observation of the classes and opted for a system based on broadcast cameras to broadcast the images live or to record them in order to reproduce them later.

In this way, observers could view the images remotely in real time and share their knowledge directly with the teacher to help improve their training.

Remote patient supervision and health training

In addition to teacher training, medical schools have had to adapt the way they teach their curriculum to incorporate students' distance learning.

Before, students used to follow doctors in the 'rounds' around the different areas of the hospital to analyze the condition of patients, treatments and possible clinical outcomes. This was an essential part of his upbringing, as it demonstrated the practical and real applications of the theory taught to them.

However, social est estinement and hygiene restrictions have greatly reduced this possibility. In this case cameras could be used to live stream the rounds of doctors, without posing an increased risk to the patient or students.

At the health center, patient supervision is a key element in providing high standards of care and treatment. Patient status can change rapidly and this control allows professionals to intervene, with the possibility of improving the results.

In situations where the preservation of personal protective equipment and the minimum reduction of the spread of the virus are a key priority, relay cameras can be used to remotely monitor patients' vital signs.

The broadcast cameras Axis provide extreme PTZ and resolution capabilities that are critical to patient monitoring situations. They also report an associated economic benefit, because the investment required for the equipment is minimal compared to other medical supplies or resources.

Raising athletic performance

As demonstrated in the two applications for previous use in different sectors, observation is a key part of the performance assessment.

In any sporting discipline, either individual or group, performance improvement goes through the possibility of carefully analyzing matches and training sessions. With this information you can make decisions to adjust and update the methods used, based on solid feedback.

This becomes particularly relevant for track and ground athletes, because they constantly analyze their movements to get results. They traditionally recorded their movements with handheld cameras, but this method had limitations, like filming angles, the start and stop of recordings and the change of memory cards.

Working with Spiideo, an Axis partner who provides sports analytics software, teams use broadcast cameras installed in the stadium to record training sessions and then analyze them on a mobile device.

Stadium security and entertainment

Stadium safety is a top priority. In fact, it is a legal requirement that they have an effective solution in this regard, and network cameras play a decisive role in this, continuously monitoring areas of the compound to detect intruders, inappropriate and illegal conduct, Etc. so that professional teams can intervene quickly if needed.

In Slovakia, all First Division League stadiums are required to use a permanent system of specific cameras, continuously monitoring individual sections of visitors, the gates and entrances to the stadium, so all the public areas inside the enclosure.

Stadium managers Spartak Myjava they were looking for a solution that complied with legal regulations and protected the facilities. In addition to providing high-quality video surveillance, operators of the venue also discovered that they could use the images to play views of the match.

Decision-making from the pitch

Pointing out a fault may be one of the most controversial decisions in a sporting and, sometimes, affects the final score. Players and fans often discuss the referee's decisions.

In addition, the arguments of the people witnessing the move may be incorrect due to the speed at which they occur or depending on the position of the person watching. An independent account of the incident helps decide whether the arbitrator's decision was justified.

This can be especially difficult in sports that are played at a breakneck pace, like hockey. An example of this is the Ontario Hockey League (Ontario Hockey League), in the United States, who was already using cameras to confirm goals and penalties, but it was found that they lacked the necessary resolution.

Axis relay cameras were installed to fix this, one oriented towards the nets and one towards the clock, allowing board officials to expand the video, frame by frame, improving their confidence in referees' decisions and allowing them to decide quickly on the results.

With a view in the future

The ability to broadcast, recording and reproducing events will remain important in many sectors, social estating guidelines and hygiene concerns prevent close contact and the gathering of groups of people.

Technology will play an increasingly important role in virtually shortening this distance and there is an opportunity for more applications to emerge in other sectors, such as transport and critical infrastructure.

Relay cameras will prove to be an essential part of this process due to their ability to produce high-resolution images in real time, which will be crucial to maintaining and enabling processes now and in the future.
