Specifications: Brand: Smart butler device name: Smart Wireless Gateway Standard: IRF Technology Voltage: DC5V 1A Power consumption: static power consumption 0.5W Operating environment: -40 ℃ ~ + 55 ℃ Material: Metal + glass RF radio frequency: 315MHz / 433MHz encrypted radio signal open environment 4000m distance wireless RF protocol: 2262 coding, coding IR 1227: support for infrared codes to send and receive instructions Carrier: infrared wireless carrier, to better ensure the stability and signal through walls advantages and features of IRF, Shenzhen City Even the United Intelligent Technology Co., based on the development of a radio frequency, infrared, Zigbee advantages of a wireless infrared technology carrier through the wall, the host sets the RF, infrared, Zigbee triple, security and stability is much higher than Zigbee, motherboard uses Independent research and development of power management chip, when the host CPU is powered off hibernation, the whole no fever increases the life of the host network Powerful Network using honeycomb structure each device can communicate with the gateway via multiple directions, break in one direction without causing equipment dropped, high network stability; for wireless LANs, broadband, 3G-4G wireless networks and other systems; and automatic intelligent networking, no configuration, really convenient 2. Powerful data ability synchronization with two-way communication, not only can send commands to the device, the device will also fed back to the execution state, which is essential for the terminal to use experience. Software uses cloud server work, can the LAN, remote login host and fast real-time control all functions 3. Wireless RF control a wide range of network encryption huge capacity, the theoretical node 65300, not only can cover family needs, to cope with the Intelligent Community, intelligent buildings, smart hotels, intelligent plant, also more than enough; 4. MANET technology, theory can cover the range of powerful encryption 50KM RF wireless control: high security, encryption using AES (Advanced Encryption System), the equivalent of a bank card encryption rigor 12 times and technology, can better protect the family of intelligent system is not being invaded interference; 5. energy saving easy to get rid of the power supply restrictions on electronic equipment, can fully battery-powered, fully realized in the future even passivity. Without the underlying communication protocol terminal equipment, automatic search after power equipment matching protocol code control and to achieve a more than one function.
