Technical Field

[0002] Surveillance cameras are ubiquitous, and smart lighting is commonplace, but most offer relatively limited functionality. With technological advancements, smart home devices are becoming increasingly integrated, and people are increasingly drawn to multifunctional, integrated products to simplify their home environments, aiming to reduce installation complexity and maintenance costs. For example, some modern smart lighting fixtures offer more than just illumination; they integrate other features, such as built-in cameras. Such integrated devices can achieve multiple functions, enabling their application in a wider range of situations. For instance, many warehouse management systems require additional surveillance to assist personnel management, especially large warehouses that necessitate multiple sets of cameras and lighting fixtures to meet their needs.
[0003] However, when choosing such multi-functional integrated devices, adding extra equipment (cameras) requires additional drilling, cabling (network cables and power supplies), and installation. This not only increases the equipment investment but also creates a messy appearance due to the cabling, increasing installation difficulty and potentially damaging lighting fixtures. Furthermore, cabling issues can detract from the aesthetics. Additionally, in areas with poor network coverage, additional network connections are needed for real-time monitoring. In all these scenarios, this represents a waste of resources and energy, hindering widespread adoption. Utility Model Content
