Technical Specifications: GPRS (CDMA) + RFID + call technical components Material: alloy & Duplicating glue bile storage mode: FLASH transmission: GPRS real-time transmission reading distance: 10 cm in size: 155mm * 47mm * 28mm Weight: 225 g Environmental Temperature: -40 ℃ to +70 ℃ Advancement: without geographical, time difference, national boundaries affect the real-time transmission, with emergency alarm call feature. Real-time: a breakthrough for nearly 20 years to pass the traditional inspection system lag, real-time feedback on-site inspection data, completed the wireless backhaul data in real-time inspection of the technical requirements of qualitative change. Combined with the distribution range of the mobile network and the extensive construction of base stations, mobile platforms can be achieved by means of real-time field data to upload, reduce the number of human factor, especially for management and requirements more stringent statistical regions and areas: the implementation of comprehensive statistics on inspection records analysis, service analysis, "a clear understanding of the table, a chart glance." Reliability: equipment using modern industrial design and manufacturing technology, strict quality control and environmental testing. Ease of use: easy installation, rain, dust, tamper, without wiring, easy to use. Authoritative: the use of multiple transmission technology, the acceptable band requires a number of countries, unified view inspection results on the Internet. Economy: Real-time, you can place a call patrol areas in technology, market, price, demand has a very strong competitive edge. Applicable industries: Emergency call handling features can be completely achieved a state of emergency alarm function, such as forestry, railway, power grids, and any areas of field operations, transport, chain operations, medical enterprises, large-scale civilian living, active environment, etc. There are strict requirements for inspections IDM.
