The rapid development of intelligent buildings has put forward higher requirements for security systems. On the one hand, in order to improve management efficiency, the security system needs to be deeply integrated with building automation, fire protection, information equipment and other systems to form a unified IBMS platform; On the other hand, as energy costs rise and environmental awareness increases, the energy-saving of security systems has become an inevitable trend. At present, the solutions in the industry are mainly reflected in two aspects: one is to use low-power hardware devices, such as low-power cameras, intelligent sensors, etc; The second is to optimize system algorithms and achieve intelligent energy management, such as automatically adjusting the brightness of monitoring equipment based on ambient light, or reducing system operating load during low-risk periods. This integrated and energy-saving strategy not only improves the overall safety and management efficiency of buildings, but also effectively reduces operating costs, which is in line with the long-term goal of intelligent building development.
