Dear Reviewer,

Thank you for your thoughtful review and positive feedback on our manuscript. We sincerely appreciate your recognition of the key contributions of our work, including:

1. The innovative use of ​infrared surface measurement​ to replace traditional contact-point temperature monitoring, expanding parameter coverage and adaptability in MCSEM system configurations.
2. The ​multi-stage anti-electromagnetic interference design​ at the circuit level, which enhances system safety beyond conventional approaches.
3. The integration of ​technologies​ (e.g., optical fiber Gigabit Ethernet and user-friendly software) to ensure real-time performance and operational safety.

Your insightful comments reinforce the value of this research, and we are grateful for your time and expertise.

Best regards,

Chentao Wang

Currently, we have revised the manuscript according to your comments, primarily focusing on the following two aspects:

(1) Carefully addressed all the issues you marked.

(2) Thoroughly investigated your query regarding Figure 16. Since we manufactured multiple infrared thermometers, each with unique calibration parameters pre-programmed in the software, it's crucial to select the correct device number during operation. The deviation shown in Figure 16 resulted from an incorrect device number selection, which affected not just the second set of measurements. We've consequently repeated the experiments with strict adherence to calibration numbers, reacquired all data, and replotted Figure 16. We sincerely appreciate your meticulous review that helped us perfect the manuscript.

Thank you very much for your detailed feedback. In the early stages of the design, we did consider Power over Ethernet (PoE) as an option. From a technical perspective, PoE technology has evolved over many years and is now at a very mature stage. However, our device was not designed for low power consumption, as its total power requirement reaches several tens of watts, which exceeds the capacity of standard PoE solutions. Typically, a PoE switch supplies power to multiple front-end IP cameras simultaneously. Any failure in the switch's PoE power module would render all connected cameras inoperable, creating an overly concentrated risk. Compared to other power supply methods, PoE technology would increase post-sales maintenance efforts. In terms of safety and stability, a dedicated power supply offers the highest reliability and security.

You are absolutely right to point this out. In our comparison, we were actually referring to the STM32F4 series of MCUs, which were commonly used in previous MCSEM systems. The A40i, on the other hand, is primarily designed for vision-based interactive industrial control products. The A40i meets industrial-grade standards, including compliance with the AEC-Q100 temperature rating. This processor is well-suited for applications requiring 3D graphics and advanced video processing. It offers rich user interfaces, high quality, low power consumption, and a high level of system integration. For our specific application scenario—which involves large-capacity storage and high-volume video data transmission—the A40i is undoubtedly a superior choice over the STM32.

Compared to FATFS (commonly used in embedded systems), Linux offers significant advantages in file management: Advanced File Systems: Supports modern file systems (e.g., ext4, Btrfs) with journaling, crash recovery, and better reliability, while FATFS lacks these features and is prone to corruption. Optimized for large files and high throughput with caching and read-ahead mechanisms, whereas FATFS suffers from fragmentation and slower I/O.

• Functionality: Includes permissions (user/group/ACL), symbolic/hard links, and network file system support (NFS/Samba), while FATFS has no security controls or advanced features.
• Scalability: Handles larger files (up to 16TB+) and partitions (1EB+), unlike FAT32’s 4GB file limit.
• Development Tools:Provides robust debugging (e.g., fsck, strace), while FATFS offers minimal troubleshooting support.

FATFS remains suitable for low-resource MCUs (e.g., STM32) or cross-platform compatibility (e.g., USB drives). However, for high-performance, reliability, or complex storage needs, Linux is the superior choice.

Thank you very much for your thorough review. This was indeed an oversight on our part. Between PLUG617 and the Baseboard, there is actually a very small adapter board that converts the Type-C interface to an FPC ribbon cable before connecting to the Baseboard. We will update the images in our subsequent submissions.

Thank you for pointing out this issue—it helps us further refine the article. In both diagrams, we have included common-mode and differential-mode capacitors to filter out corresponding interference. We will elaborate on this design in our subsequent revisions.

Regarding Questions 6 and 7, we will carefully refine the language and standardize the expression of formulas in our subsequent revisions. Thank you once again for raising these issues.
