Oil seals work by creating a tight seal around the rotating shaft. This prevents oil and other fluids from escaping while allowing the shaft to rotate smoothly. The seal is usually made up of a lip that fits snugly against the shaft, preventing any leaks from occurring. Some oil seals also have additional features, such as springs or gaskets, to provide extra support and ensure a secure fit.

In addition to surveillance, access control has become increasingly sophisticated. Traditional key management is being replaced by electronic access control systems, which use key cards, biometric scanners, or mobile devices to grant entry. These systems not only provide a higher level of security but also offer the ability to track and manage access in real-time. This is particularly important in corporate settings where sensitive information must be protected from unauthorized individuals.
