Each camera placement serves a specific purpose, whether it's providing a broader view of the race, capturing the raw intensity, focusing on the driver's experience, or showcasing the mechanical intricacies of the vehicle. These different perspectives come together to provide a comprehensive view of the race, engaging viewers and offering them a unique and immersive experience.

Camera control: manned vs unmanned

The use of manned vs unmanned cameras is a key consideration for race car teams and broadcasters. Both options have their own advantages and disadvantages, and the choice depends on the specific requirements and constraints of the project.

Manned Camera Control

Manned camera control refers to the use of a camera operator who is physically present in the vehicle to control the camera and capture footage. This option offers several benefits. Firstly, manned camera control ensures safer operations compared to unmanned systems, as proven by their extensive use in NASCAR races. Manned systems are also more versatile, as they can be used for both small and large projects, and are capable of carrying multiple high-end mapping sensors and heavy payloads. Additionally, manned aircraft are more airspace-friendly, as they have fewer restrictions when flying over people and can be authorised by the Federal Aviation Administration (FAA) to fly over almost any project.

However, there are also drawbacks to manned camera control. One of the main disadvantages is the high cost of operation. Manned aircraft are expensive to own, maintain, and fuel, which increases the overall cost of the project. Manned operations also typically require a sensor operator in addition to the pilot, further adding to the expense. Manned systems may not be suitable for very small projects due to their high operational costs, and they generally provide lower-resolution imagery compared to unmanned systems.

Unmanned Camera Control

Unmanned camera control, on the other hand, involves the use of remote-controlled or autonomous cameras without the physical presence of a camera operator. This option has gained popularity due to its low cost and high-resolution imagery. Unmanned systems, such as small unmanned aircraft systems (sUAS or UAS), are ideal for projects that are too small for manned aircraft, as they are more affordable and easier to mobilise. They can be shipped as cargo or checked in as luggage, and they do not require an additional sensor operator. Unmanned systems can capture high-resolution imagery due to their low flying altitude, typically under 400 feet AGL.

However, unmanned camera control also has its limitations. Unmanned systems are not suitable for large projects due to their low speed and endurance. They have limited payload capacity and cannot carry heavy, high-end mapping sensors. Additionally, they are subject to FAA regulations that restrict their flying altitude and prohibit them from flying over people, limiting their use in certain projects.

In conclusion, both manned and unmanned camera control have their strengths and weaknesses. Manned camera control is more versatile, safer, and has fewer restrictions, but it is more expensive and may not be suitable for very small projects. On the other hand, unmanned camera control is more affordable, ideal for small projects, and provides high-resolution imagery, but it is limited by speed, endurance, payload capacity, and regulatory constraints. The choice between manned and unmanned camera control ultimately depends on the specific requirements and budget of the race car team and broadcasters.

Camera impact: on car weight, aerodynamics, and performance

Motor racing organisations have been using in-car camera systems, such as RaceCam, since the 1970s. These systems involve a network of car-mounted cameras, microwave radio transmitters, and relays from helicopters to broadcast live images from inside a race car to both pit crews and television audiences.

Camera Impact on Car Weight

Cameras and their associated equipment add weight to a race car. This can affect the car's performance, handling, and fuel efficiency. However, in races like IndyCar, rules ensure that cars without cameras carry equivalent ballast to ensure all vehicles have similar weight characteristics. This rule helps maintain a level playing field for all competitors, regardless of whether they are carrying cameras or not.

Camera Impact on Aerodynamics

The positioning of cameras and their housings on a race car can impact its aerodynamics. In Formula One, for example, streamlined "camera pods" are mounted above each car's airbox, affecting the airflow around the vehicle. To minimise aerodynamic disruptions, Formula One regulations mandate the placement of cameras in specific predetermined positions. This ensures that all cars have similar aerodynamic profiles, whether they are carrying cameras or not.

Camera Impact on Performance

The presence of cameras in a race car can have a direct impact on its performance. The additional weight of the cameras and equipment can influence the car's acceleration, top speed, and handling characteristics. Additionally, the positioning of the cameras and their housings can affect the car's aerodynamics, drag, and overall performance. However, advancements in camera technology have led to the development of miniature cameras, such as the "Driver's Eye" camera, which can be integrated into a driver's helmet without significantly impacting their field of view or the car's performance.

In conclusion, while cameras can have an impact on a race car's weight, aerodynamics, and performance, motor racing organisations and regulations have adapted to minimise these effects. The use of lightweight camera equipment, specific mounting positions, and ballast rules help ensure that all competitors have a fair chance, regardless of whether they are carrying cameras or not.
