The YM04 intelligent access control system has expanded its operating temperature range to -30°C to 60°C, which not only enables it to withstand the severe cold in the north but also adapts to the high temperatures in regions such as Xinjiang and Hainan during the summer. This solves the common problem with traditional access control systems, which are vulnerable to freezing in winter and overheating in summer. As a result, the YM04 can operate reliably in all parts of the country, outperforming similar products in terms of geographical compatibility. The durability of the outdoor unit is truly designed for outdoor use. The casing is made of a composite material of aluminum alloy and ABS, which retains the aluminum alloy’s resistance to impact and aging while also achieving lightweightness through the ABS material. The overall dimensions of the device are 130×90×40mm, making it easy to install without being conspicuous. It also boasts professional waterproof and dustproof capabilities, effectively protecting the internal components from harsh weather conditions such as heavy rain, sandstorms, and snow, thus preventing short circuits and damage, and significantly reducing maintenance costs. The practicality of the night vision function has also been enhanced. The YM04 outdoor unit is equipped with a night vision illumination system with a sensitivity as low as 0.1Lux, allowing it to activate night vision mode even in low-light environments. It can produce clear black-and-white images within a core monitoring range of 0.2 to 1.5 meters, ensuring that visitors can be identified at night. This design meets the essential security needs of residential unit doors and shops at night, avoiding identification issues caused by poor lighting. The energy consumption control continues the series’ strengths: the standby power consumption of the outdoor unit is ≤2W, and the power consumption during operation is ≤5W; the indoor unit consumes <10W during operation and <1W in standby mode. With a 15V 1.2A power adapter, the long-term electrical costs are very low. For scenarios such as residential complexes and factories that require 24-hour operation, the low energy consumption is a significant advantage.
