The legendary Wave Pool in the Valley of Waves is the main attraction in Sun City’s famous water park. Here, visitors find their place in the sun, with two-metre-high waves shooting into the air every 90 seconds. But where there is a lot of light, there is also plenty of shadow, which comes in the form of pickpocketing and, occasionally, swimming accidents.
With a video technology solution from Regensburg-based German manufacturer Dallmeier, the Sun City Resort has been able to significantly improve its customer experience.
Due to the size of the resort, it’s a daunting task to monitor the movements of all residents and day visitors in the Valley of Waves and therefore, as in any amusement park, it’s unfortunately unavoidable to be accountable for the actions of Valley users. By using Dallmeier’s patented Panomera multifocal sensor cameras and SeMSy video management software, the operators have succeeded in effectively managing their liability for the safety of all visitors to the Valley. In the event of an accident, the company also has access to easy-to-use video documentation. This makes it possible to accurately reconstruct the causes of accidents and take appropriate action.
No sunbathing under cameras
The challenge was to reconcile the security interests of the visitors and the desire to improve customer service with the expectation of a carefree stay at the beach. Of course, there are signs pointing out the video security technology in place, but it is unlikely that guests want to be constantly confronted with the sight of cameras.
“This was also the classic paradox of many security solutions: How can you secure an entire beach area in such a way that visitors are protected in the best possible way, but do not feel harassed?” says Hendrik Strauss, Resort Security Manager at Sun City. “It quickly became clear to us that the right choice of technology would play a central role in this initial situation.”
Only three systems for over 16 000 m2
In these conditions, and after extensive testing, conventional camera technology was ruled out. The images were simply not accurate enough, or the operator would have had to ‘spike’ the site with many cameras. In the end, the surveillance department opted for the patented Panomera multifocal sensor technology from Dallmeier.
“These cameras solve the optical dilemma of decreasing resolution in depth or distance by combining multiple sensors with lenses of different focal lengths,” says Johnathan Rieder, CCTV Technician at Sun International, explaining the technology. “In this way, the systems provide a consistently high-resolution image of the entire object space, including the rear image areas – and for the entire area of just over 16 000 m2, the operator only needs three Panomera S8 Ultraline camera systems. At the end of the day, the operators are looking at a single overall image; with standard 4K cameras, this would quickly be 20 – 24 individual images.”
Maximum overview with all the details
The images from these lenses are then stitched together by software to form an overall image – eight individual images are combined to form one overall image. This means that the operator always has a complete overview during live observation, as the entire terrain is displayed on just three monitors. If required, any section of the overall image can be selected with the mouse and opened in a separate window. Operators can zoom into these detailed views as required, enabling them to identify and track details with precision.
Any number of these detailed views can be opened at the same time and this function is available in live operation, but also in the recording. This provides Sun City’s security experts with a powerful tool for investigating crimes or determining the exact cause of an accident.
Bright beach, dark forest
Another advantage of the technology is that, with eight individual sensors available for each image, the problem of large differences in brightness can be solved. After all, each of the sensors must only adjust to the differences in brightness in exactly the image area for which it is responsible. And in the Valley of Waves, the contrasts could not be greater: The terrain includes both bright sandy beaches and the adjacent tropical rainforest – a huge challenge for any imaging system.
Customer experience improved
“We have been using Dallmeier’s standard camera technology and the company’s SeMSy video and alarm management system, indoors, in the casino for years. We have a total of around 1200 cameras and are still convinced of the quality of the systems,” says Strauss. “So, it made sense for us to also use Dallmeier in the outdoor area as well. Especially as there is simply no camera technology on the market that meets our key requirements. Maximum improvement of the customer experience with minimum visibility.”
Panomera S8 Ultraline
The combination of the high-resolution sensors of the Panomera S8 Ultraline offers a dynamic range of 130 dB UWDR effectively, and results in an extreme ‘Panomera’ effect. It offers a resolution of more than 125 px/m up to a distance of 160, 104 or 82 metres, which enables the recognition of persons over the entire distance. The identification of persons (250 px/m) is supported up to a distance of 46 metres depending on the model.
The sensors of the Panomera are equipped with the hardened Linux operating system DOMERA OS. In addition to a kernel with long-term support, it offers extensive security functions, such as the deactivation of unused ports, or the enforcement of strict passwords. In addition, DOMERA OS supports secure network authentication (IEEE 802.1X) and encrypted data transmission (TLS 1.2/AES-256). All software components are subject to permanent monitoring, maintenance and updating, while the effectiveness of all measures is ensured by regular external penetration tests.
The Panomera is equipped with an intensively trained neural network that analyses the captured images in high resolution and is independent of movements in the background (green spaces, water areas, etc.). It reliably classifies defined objects (persons, vehicles, etc.) in real time. The captured data is sent, with the video stream, to the Dallmeier recording system for evaluation and storage, and is available for further processing with the integrated EdgeAnalytics apps.
The embedded EdgeAnalytics AI apps use the raw data of the Deep AI Object Classification to assess the captured operations according to the specific criteria of various use cases. The Line Crossing App, for example, detects the crossing of a defined line by a relevant object (person, vehicle, etc.) and generates a corresponding message with time and direction of movement. The generated event messages and values complete the raw data already contained in the video stream and can be displayed and evaluated with a Dallmeier client software.
