BTD4212-DX-25 module-LTE technology+wide-temperature design, with no downtime in extreme environment. The core requirement of patrol scene for communication equipment is "lasting stability", and the module BTD4212-DX-25 of Yanuoxun is perfectly adapted by virtue of the advantages of LTE technology. As a key model of BTD Series, it’s a leading choice for patrol scenarios. As a leading provider of image Transmission solutions in China, Yanuoxun takes the domestic SOC chip as the core, which makes this module find a balance between low power consumption and signal stability-4W ultra-low power consumption supports solar power supply, especially suitable for remote patrol areas without power grid coverage. Aiming at the dual requirements of "fixed+mobile" patrol, the module, as part of Wireless Video Transmission Modules, has designed a flexible networking mode: 50KM star network can cover a wide range of patrol areas, and 10KM mesh ad hoc network can make mobile patrol cars and fixed monitoring points linked in real time. The design of single transmission and double reception ensures stable signal reception, and the code rate of 30Mbps meets the clear transmission of patrol pictures. In terms of hardware, IP65 waterproof rating is the "just-needed protection" for outdoor patrol, which can resist rain, snow and dust. The wide temperature design of -40℃~+70℃ is suitable for the whole climatic zone from severe cold in the northeast to intense heat in the south. Unlike BTF Series that focuses on ultra-long-distance transmission, it emphasizes stability in fixed and mobile patrols. The simple interface of 1 network port+1 power port is convenient for rapid installation on patrol towers and moving vehicles without complicated debugging. From the practical application, the module has become the "invisible sentry" of the patrol scene: when patrolling the border, it sends the picture of no man's land back to the command center in real time; During the night patrol in the park, the infrared camera can be linked to capture abnormal dynamics. The combination of low power consumption and high reliability makes it an ideal choice for long-term patrol monitoring. FAQ： 1.Can the module start normally in the cold environment of-40℃? It supports wide temperature operation from-40℃ to+70℃, and can normally start and transmit signals even in extremely cold weather in the north, which is suitable for border patrol in winter. 2.What are the advantages of single Engine and double receiver design? Single transmission ensures stable signal transmission, and double reception improves the fault tolerance rate of signal reception, which can reduce the picture jam or interruption even in the patrol area with weak signal. 3.Is it suitable for fixed installation or mobile patrol? Give consideration to both-fixed installation in the patrol tower can realize long-term monitoring, and mounted in the patrol car can realize mobile duty, adapting to the dual patrol demand of "fixed+mobile". 4.Is triple encryption (ZUC, SNOW3G, AES128) necessary? It is necessary that patrol data (such as border defense location and personnel flow in the park) are related to security, and triple encryption can meet the needs of different security levels to ensure data security.
